The Lighter Frigate Debate: A Look "Under the Hood"


"Was I to die this moment, 'Want of Frigates' would be found stamped on my heart. No words of mine can express what I have, and am suffering for want of them."
-Horatio Nelson, August 1798

As those who have read my musings on the "lighter frigate" in the past may already know my views on the British government's plan, laid down in the 2015 strategic defence and security review, have been mixed. To some extent I continue to blow hot and cold on the issue. It is now apparent, to me at least, that there is risk inherent in all courses of action when it comes to replacing the Royal Navy's thirteen aging Type 23 frigates. The earlier plan, to build thirteen Type 26 frigates, appears to have fallen afoul of cost and potentially timescale issues. We can criticise the decision to cap the Type 26 build run at the eight anti-submarine configured hulls all we like, but the reality appears to be that BAE's construction yards on the Clyde could not deliver Type 26 at the required tempo without very significant investment (the "frigate factory"). One shipbuild per year was needed to replace the Type 23s as they leave service, without a significant decline in RN escort numbers, whereas the yard currently appears to be scaled for one Type 26 scale shipbuild per 1.5 years.

Presuming that BAE could have delivered at the specified rate of one Type 26 build every 1.5 years it would have resulted in a dramatic decline in the RN's number of escorts, with no realistic chance of recovery until the early 2040s. It would also have likely resulted in a concurrent construction programme, using the same yards, with the Type 45's replacement in the mid-late 2030s. This would have required the Clyde yards to at least double their output of complex warships, a hard ask indeed.


The 13 Type 26 option clearly had some significant problems of its own. It was by no means an "easy" option, requiring a 33% higher build rate than BAE were required to provide under their Terms of Business Agreement with the government, significant investment in new facilities to achieve that higher build rate. Coupled with a higher rate of orders than the MoD was likely capable of funding, without compromising other programmes and we've probably explained the majority of the "witches' brew" that produced the 2015 decision to cap Type 26 at eight hulls and build five or more "lighter frigates".

It's fair to say that this decision has caused more than its fair share of controversy amongst defence commentators. During these early stages hard facts have been very thin on the ground. Most of what we have to go on is based on a few "powerpoint" design concepts put out by BAE, BMT Defence Services and Stellar Systems and Sir John Parker's recommendations for reforming the UK military shipbuilding sector. Bluntly, it isn't a lot and until the government releases its "National Shipbuilding Strategy" at some point soon(ish) we will continue to speculate about the "Lighter Frigate/General Purpose Frigate/Type 31/Type 31e", mostly in the dark. 

It's been suggested that the Lighter Frigate essentially amounts to the "anyone but BAE" option and is a means of undermining their near-monopolistic position in UK military shipbuilding. For some commentators this prospect is deeply worrying, having the potential to fatally undermine the two remaining complex military shipbuilding sites in the country by starving them of orders. For others BAE's monopoly is painted as "the problem" and one of the key reasons why UK-built warships are more expensive than their overseas equivalents. I'm, personally, more inclined to agree with the former position. However, I also see the need for the Lighter Frigate and recognise that it isn't an entirely bad idea from several standpoints.


Firstly, even with a 25% slower build tempo, one Lighter Frigate every two years, escort numbers remain relatively stable; dipping to lows of only 18. 

Secondly, 8 Type 26 at 1.5 year intervals dovetail neatly with the projected start of the Type 45 replacement programme without the need for concurrency. This indicates to me that the "Lighter Frigate undermines BAE" argument may be too harsh. There is a steady stream of the sort of high-end complex warship building work that BAE provides on the Clyde available for those yards well into the future. 

Thirdly, one of the most astute criticisms is that bringing the Lighter Frigate from the concept stage, where we are at present, to a full-fledged design able to be built is going to take time and cost money. This is absolutely the case and where much of the risk lies. However, it is not impossible to design and develop a surface escort to a constrained timescale. Doing so may actually help avoid the problems which emerge when a steady stream of additions and amendemnts are made to a design specification the longer it takes to bring it to fruition. A process that, as Type 26 demonstrates, can add significantly to development costs. It may also limit the scope for bespoke or "revolutionary" components, with designers forced to turn to off the shelf equipment and machinery. A more constrained timescale for designing the Lighter Frigate may actually prove beneficial if it produces a well-executed, but conservative, design.

An earlier and much more modest iteration of Type 26

Fourth, there is justified concern about the viability of the proposed "block build" approach that is intended to spread work to other, smaller, yards around the UK. There are evidently issues with this approach related to the shortage of yards with the necessary skilled workforce, equipment and facilities to efficiently build blocks for a complex surface combatant. While work on blocks for the carriers appears to be a positive indication of their skills and capacity to deliver, it remains to be seen if a similar model can be made to work for the Lighter Frigate. The other issue with this approach is the apparent lack of a suitable "integration yard" (where the blocks are assembled into a functioning warship).

"The vessel should be assembled in a shipyard, backed by a company or alliance with sufficient financial and industrial capacity and capability to construct and commission and enter into the key sub-contracts."
-Parker Report, 2016

There are a very limited set of options on this front. While Sir John Parker's report suggests that BAE should concentrate their efforts on Type 26 their yards on the Clyde would be an obvious option, provided that the risk of concurrently building Type 26 and integrating blocks for the Lighter Frigate could be mitigated. Unfortunately viable alternatives are very thin on the ground. Babcock international's Appledore yard is too small and their Rosyth yard, where the carriers have been constructed, is soon to become the hub for UK nuclear submarine decommissioning. Cammel Laird on Merseyside have the facilities but likely lack the skilled workforce necessary to integrate a complex warship. Their performance constructing the UK polar research ship RRS David Attenborough may give some indication of just how capable they are in this regard. Harland and Wolff's yard in Belfast is large enough, but the company hasn't built ships (let alone anything as complex as a warship) for years, having diversified heavily into the offshore wind sector. Other "options", such as re-opening the Portsmouth construction yard, are little more than fantasy.

The options for the integration yard are extremely limited, realistically boiling down to BAE on the Clyde and Cammel Laird. The latter being a much more risky option that would almost certainly require a consortium that included BAE, to bring their skills and experience to bear, in order to make it work. It would also likely require an expansion and upskilling of Cammel Laird's modestly-sized workforce. Ultimately it might be better to focus efforts on a single complex builder, BAE on the Clyde. However, this could introduce risks to the Type 26 programme. The optimal means of mitigating those risks might be to use BAE as an assembly yard only for the Lighter Frigate, keeping all fabrication activities seperate by farming them out to the smaller yards.

Cammel Laird's yard in Merseyside
If the UK government is serious about building up a second complex military shipbuilder, it needs to consider the implications on continued investment in the Royal Navy and Fleet Auxiliary that will be necessary to sustain two yards. In shipbuilding consistent investment and orders are critical. It will be no different in this case than it is with BAE.

Overall, the Lighter Frigate is simultaneously necessary and difficult to realise. Contrary to some commentators' views, I'm firm in my belief that 13 Type 26 isn't the "magic wand" answer to this problem. A long-term failure to invest in military shipbuilding has led us to a place where there are no easy options. Blaming all of our woes on BAE's monopoly is unhelpful and disguises systematic failures in the government's military industrial strategy. "Competition" isn't a magic wand either, undermining BAE with no real alternative would be the height of irresponsibility. The only way to make a semi-competitive military shipbuilding system work would be to build a significantly larger Royal Navy, able to naturally support more than one major yard. In the author's opinion, the optimum solution would be to use BAE's Clyde yards as the integrator for the Lighter Frigate. Accepting the risk to Type 26 by giving BAE the confidence to invest seriously in their yards and expand the workforce to cope with concurrent builds. The alternative, Cammel Laird, is probably just too much of a leap in the dark at this stage. 

In the end this is about providing the navy with the number of ships it needs to carry out its duties while maintaining a sustainable military shipbuilding sector. 

Oh, and the idea that the UK will export loads of these things is probably bollocks.

Size Matters: Britain's Aircraft Carriers



"The aircraft carrier is truly amazing. I am amazed at the concept of the carrier, and the fact that it works. And it doesn't just work, it kicks butt.

-Lt. Barry W. Hull, VFA-81 Squadron, USS Saratoga, 1991

Why build big? It's a simple question asked frequently about the UK's two new Queen Elizabeth class aircraft carriers. Weighing in at just over 70,000 tonnes they are, by quite a long way, "the largest ships ever built for the Royal Navy". Many have leveled criticisms against them because of their size, claiming they are little more than a vast vanity project, that their size makes them unsuitable for a "medium power" such as Britain and that they reflect a yearning for a status on the world stage that is undeserved. What these criticisms ignore is that there are serious practical reasons why larger carriers are, in most circumstances, a significantly better investment when compared with smaller "pocket carriers" such as the Invincible class ships the UK operated from the late 70s through to 2014; when HMS Illustrious was decommissioned.

Efficiency:
Probably the key reason why larger carriers are significantly better than their smaller cousins is that they are a more efficient way of sustaining air operations from the sea. Generating the same effect with numerous smaller carriers, as some have suggested as a better course for the UK to follow, simply costs much more. The obvious consequence of this is that you get a force of smaller carriers that cannot deliver the same effect as fewer, larger, ships. The reason why this is the case can be neatly summed up with a single word: duplication. This is especially true of the manpower required to run two equivalent carrier forces, equal in "striking power", where the only difference is the size of the ships.  While the individual light carrier will undoubtedly have a smaller crew than an individual large carrier, you might need two or three smaller carriers to achieve the same number of sorties as a single, larger, ship and each still requires a range of highly trained crew members. To draw upon a real-world example: HMS Queen Elizabeth has a core crew of ~679, will carry and operate a tailored air group of 40 aircraft and can surge 110+ sorties a day. In comparison the 25,000t ITS Cavour has a core crew of ~451, an air group of around 20 aircraft and can surge approximately ~40 sorties a day. This means that, broadly speaking, in order to achieve the same effect as a single Queen Elizabeth you need approximately three Cavour-style light carriers on station, with manpower equivalent to double that of the larger ship. When considering the force structure necessary to ensure there are three small carriers available at all times for operations, taking the Royal Navy's current ratio of around 2 ships in maintenance for every 3 ships operationally available, you're looking at a fleet of five light carriers to achieve the same notional operational effect as a pair of Queen Elizabeths. Overall the model of smaller, more numerous, ships would require between 20 and 35% more manpower across the entire carrier force. At a time when the Royal Navy is hard-pressed to man its existing fleet a solution that involves adding up to a third more ship-side manpower to the carrier force is simply impractical and would add substantially to the force's through-life running cost.

As the ships get smaller their efficiency decreases markedly. Concepts for extremely small VTOL carriers, such as the one illustrated below, essentially amount to a reductio ad absurdum but nevertheless prove the point that greater numbers of smaller carriers become exponentially more expensive to produce the same effect in terms of available aircraft and sortie generation. Furthermore, there is also needless duplication in terms of aircraft maintainers with small carriers. It takes a similar number of trained engineers to maintain a small number of aircraft operated from a small carrier as it does to maintain a larger number on a larger carrier, once again duplication of functions across multiple platforms leads to greater manpower needs, reduced efficiency and increased costs across the entire fleet. The cost of the ship per aircraft carried also increases significantly as the platform becomes smaller. Taking into account that the RN, when presented with the opportunity to replace their old carriers, was instructed by the government that no more than two new ships would be procured it then becomes clear that two larger ships were the clear and preferable choice.

Sustained Operations:
The next major limitation on many smaller carrier designs is their capacity to conduct sustained air operations. This is due to a number of factors, but principally comes down to aircrew endurance, aircraft maintenance and supply limitations. As you can well imagine it is easier for a carrier with a larger air wing to conduct more sorties in a short-term high-intensity surge effort, however, their advantage becomes even more obvious when looking at sustaining a more modest number of sorties over a longer period of time. Facilities for planning and briefing multiple air operations are also more limited aboard smaller ships. Light carriers with smaller air groups place greater demands on a smaller pool of pilots and other air crew when sustaining operations over time, or compromise by reducing the number of sorties flown. Similarly, working a smaller number of aircraft harder to sustain operations leads to greater wear on individual aircraft, increasing the risk that they end up out of action without an available replacement. For example, during NATO bombing operations in 1995 Britain's "pocket carrier" HMS Invincible was struggling to sustain eight sorties a day with her eight embarked Sea Harrier FA.2s (and both Sea Harrier models had a reputation for being robust and reliable aircraft). A larger carrier with more aircraft embarked can better afford technical problems which prevent some aircraft from operating, because each individual aircraft's availability is less important when a large pool is available to draw from.

Logistics are also another crucial advantage of larger carriers, as greater space for fuel and stores makes them less reliant on frequent resupply operations which take time and prevent flying operations. The Invincible class were (despite some mid-life improvements to the quantity of ammunition they could store in their magazines) always tied very closely to their attendant fuel and stores ships. By comparison the Queen Elizabeth design can hold fuel and stores for around ~400 "strike" sorties, sufficient for five days of very high-intensity operations (defined as a first-day Surge of 110 sorties, followed by 72 sorties a day for four days) before needing to come "off station" in order to resupply fuel and ammunition. Alternatively, a more relaxed tempo could obviously be sustained over a longer period of time. Considering that the Libya air policing mission only required 36 sorties per day to enforce, after the first 11 days spent degrading Libya's air defences, QE could sustain a similar lower tempo operation without resupply for 11 days.

The Invincible class light carriers struggled to sustain air operations for an extended duration without reduced sortie rates and heavy dependence on attendant logistics ships.


Eggs and Baskets:
There is a superficially appealing argument that reliance on a smaller number of larger ships amounts to "placing all of one's eggs into a few very expensive baskets". While this may sound like an enlightened nugget of wisdom on the surface, dig a little deeper and you find that it's a flawed argument. Firstly, "hardening" a carrier force by using a greater number of smaller platforms only works if you have the escort warships to form multiple carrier groups. Without a sufficient number of these ships, which form a vital part of the carrier's layered defences, the available escorts will either be too thinly spread to be effective, or the carriers will have to be concentrated within the protected zone afforded by the available escorts. The first approach risks spreading available forces too thinly, dispersing them into vulnerable "penny packets", while the second only provides marginal benefits over having a single larger ship at the centre of the carrier group. Effective dispersal of the carrier force would multiply the number of effective escort groups required, something that is beyond the current capabilities of the Royal Navy. Secondly, a more dispersed carrier force would also require the dispersal of logistics support ships. As presently planned the UK carrier group will be supported by a large fleet tanker and solid stores ship, in comparison multiple smaller carriers would each require a roughly equivalent number of support ships (and would be more dependent on them, as their own fuel and magazine space would be more limited). If, broadly speaking, three smaller carriers are necessary to replicate the capability of a single larger carrier then the overall force will require something like triple the number of logistics ships and escorts; if the carriers are operated separately in order to take advantage of the dispersed approach. Even then, each group centered on a light carrier will have fewer aircraft available to contribute to the outer ring of its layered defense. This means that Combat Air Patrol (CAP) operations, designed to keep hostile aircraft away from the carrier group, would require a greater portion of the air group's effort and leave fewer aircraft available for offensive operations. What this means in practice is that the smaller carrier would be expending so much effort protecting itself and its escort group that its "punch" would end up being anemic.



The alternative approach to effective dispersal is concentrating multiple smaller carriers within the same group. This does have the clear benefits of not requiring nearly as many additional escorts and also limits the need to duplicate replenishment ships. The group's "punch" is also greater, due to the larger number of available aircraft for all duties, albeit spread between a number of ships rather than concentrated on one. Indeed, the concentrated approach was taken by the commander of the British naval task force that fought the 1982 Falklands War; with HMS Hermes and HMS Invincible operating together throughout most of the conflict. However, it is important to note that this means of employing smaller carriers sacrifices the key benefits of effective dispersal: the increased difficulty of locating the entire carrier force for the enemy, the ability to deploy the dispersed groups to different areas and the increased "coverage" this can provide (especially for anti-submarine operations). It is a fundamental principle of military operations that force be concentrated in order to achieve decisive effects, while a dispersed force may allow individual platforms to survive it is far less useful for striking hard blows against an adversary.
Operating a dispersed force of smaller carriers requires significantly more escorts and logistics ships and must still be concentrated in order to achieve decisive military effects in most circumstances.
Conclusions:
I began this piece with a simple question: "why build big?" and the answer is now clear. When discussing aircraft carriers, from a purely functional perspective, size matters. Setting aside the soft power and symbolic implications of operating large carriers entirely, they're simply better from a pragmatic position. Smaller numbers of larger carriers are more efficient in terms of manpower, cost per aircraft carried and supporting ships than larger numbers of smaller carriers. For the Royal Navy, told that they would only get two ships to replace the remaining Invincible class carriers, the decision was clear and they chose to build two large, efficient and effective ships. This was, for all of the reasons discussed, absolutely the right decision for the UK. The new Queen Elizabeth class, once fully worked up, will be capable of conducting extremely intensive "short and sharp" air operations before exhausting her own supplies of fuel and ammunition or sustaining a lower tempo of operation for a significant time. They will be able to bring a decisive level of force to most engagements, instead of the small "penny packets" of aircraft aboard light carriers. Along with a properly constituted escort group the larger carrier is also capable of simultaneously defending itself and conducting meaningful strike operations when necessary. For those who claim that the UK's large carriers are simple a vanity project I would respond by stating that deliberately pursuing a more expensive and less effective solution, in the form of smaller carriers, because of a perception that they "better suit Britain's position in the world" is not only vain but unnecessarily introspective and downright foolish. When it comes to carriers, the UK has absolutely made the right choice. Bigger is better.

A Nation in Retreat: Britain's Continental Century


"Whereas any European power has to support a vast army first of all, we in this fortunate, happy island, relieved by our insular position of a double burden, may turn our undivided efforts and attention to the fleet. Why should we sacrifice a game in which we are sure to win to play a game in which we are bound to lose?"
-Winston Churchill

Britain's twentieth century was defined, for the first time in over five hundred years, by a monumental shift in national strategy. The maritime approach, upon which the country had built its wealth and power, was founded on the principle of limited coercive action delivered by mobile naval forces. In the twentieth century this was abandoned in favour of a less than limited continental military strategy that, with hindsight, proved to be disastrous. The forces created to fight two World Wars, deal with the increasing burdens from imperial defence and later the Cold War, managed decolonisation and the 'Global War on Terror' have severely limited the country's ability to project power in defence of its interests.

It's difficult to pinpoint exactly where the change began, but it was likely after the Second Boer War. Britain has just emerged from a bloody three year long conflict against the Dutch Boer settlers of the Orange Free State and South African Republic. For the first time in many years Britain faced a colonial opponent that they did not technologically over match. While their near-absolute naval dominance meant that no great power dared to seriously intervene in the conflict, although a number flirted with the idea, it could not provide a solution to the challenge posed by the Boers. Instead an enormous, by British standards, Imperial land army of 500,000 troops was raised and used to effectively bludgeon the ~80,000 Boer fighters into submission. The cost was enormous: £210 million at the time, which equates to over £200 billion in today's money. More important than the financial cost though were the lessons drawn from the war by the British establishment, and applied in the Haldane reforms of 1906-1912.

The changes to the British army that were effected could not have come at a worse time. They stipulated the need for a large six division strong regular intervention force, to be deployed to the continent in the event of a major war. This would be backed up by the even larger fourteen division strong Territorial force, who would provide follow on forces and replace losses amongst the regular formations. While the reforms also included welcome changes, such as the professionalisation of the Officer Corps and the development of an Imperial General Staff, they effectively committed Britain to the deployment of a large land army in the event of a major European war. Just two years later Britain was plunged into just such a war. The structure worked exactly as planned in 1914, the 100,000 strong British Expeditionary Force (BEF) mobilised swiftly and deployed to the continent without loss, protected by a Royal Navy that was still overwhelmingly superior to its opposition. Once ashore, however, events did not unfold as some had expected. The intense fire of a modern industrial war burned through the original BEF, the "old contemptibles", in the opening campaign of 1914. 1915 swallowed the fourteen Territorial divisions, and the regular BEF built by Haldane had effectively ceased to exist by the end of the Second Battle of Ypres.

What made the First World War different though wasn't that Britain's small army was chewed up by its larger continental foes, but what came next. The Secretary of State for War, Lord Kitchiner, in 1914 implemented a plan to build an enormous volunteer "New Army" of sixty divisions: some two million men strong. When the volunteers dried up the government turned, for the first time, to mass conscription to fill the ranks of the army. The First World War was the moment when the UK went from flirting with the idea of continental land power, as a solution to certain tactical problems, to actually basing it's national strategy around it. Nobody will know if the First World War could have been won with a radically different British strategy, using it's peerless strength at sea to greater effect. The French Revolutionary and Napoleonic wars seem to suggest that an expansionist militaristic European power, trapped in Europe and blockaded by a naval power, would sooner or later overreach and collapse in the face of its enemies. Such a war would not have been quick or easy, but might have avoided much of the sacrifice of the Western Front, and the many hundreds of thousands of British and Empire lives lost there. It is also debatable that had Britain's political leaders been clearer in their diplomacy, and more willing to actively deter Imperial Germany with the Royal Navy, the war may have been avoided altogether.

It is needless to say that the war proved a profound shock to a country whose last real experience of continental power ended with the conclusion of the Hundred Years War in 1453, and the steady loss thereafter of the last major pieces of the continental empire built by the Plantagenet dynasty. The sheer trauma of the First World War embedded itself into Britain's society, comprehensively destroying the pervasive national confidence of the nineteenth century. The Britain of 1919 was a shadow of its former self, while still an impressive Imperial titan, the system was becoming increasingly hollow at the centre. The UK had borrowed enormous sums of money during the war to loan to it's allies: France and Russia. When Tzar Nicholas II, and later the pro-western provisional government of Alexander Kerensky, were overthrown in 1917 by Bolshevik Communists any hope that Britain would see its money back from the loans it had given the Russian government evaporated. Britain's war debts were enormous, standing at ~175% of GDP in 1920. However, it was the interest on that debt that did the real damage. In 1914 the interest on the UK's national debt stood at just over 2% of GDP; by 1920 it was 6%, between 1924 and 1934 it hovered around 9% before steadily declining until 1939. For a full decade a tenth of the UK's GDP was being used up just servicing it's debts from the First World War. Understandably, such ruinous levels of debt imposed severe burdens on the British government, leading them to pursue arms reduction as a means of controlling national expenditure.
What was worse than the war debt though, was the damage inflicted upon the British population. Three quarters of a million men from the British isles were killed in the conflict, around 2% of the 1914 population, with a further 1.7 million wounded. 17% of serving officers were killed during the war, inflicting severe damage to the upper and middle classes they were commonly drawn from. Unlike in the Napoleonic wars Britain sacrificed a generation of its future leaders in the First World War. Many of whom would have contributed to the post-war economic recovery

The Washington Naval Treaties of 1922 and 1936 surely stand as a testament to the decline in Britain's power, forced on them by the long term costs of the First World War. The "two power standard", which stipulated that the Royal Navy be equal in strength to the fleets of the next two great powers combined, was relinquished for simple parity with the second naval power: the United States. Britain likely avoided a costly naval race, and worsening relations with the Americans, but sacrificed a century of supremacy at sea with the stroke of a pen. What's worse, the dearth in naval shipbuilding caused a significant contraction in Britain's naval construction capacity. While civilian yards could still be contracted to mass produce simple designs in wartime, bottlenecks in the fabrication of armour plate, large naval guns and complex equipment severely limited Britain's ability to re-equip the navy in the late inter-war years.

British planners tried to grapple with the problems of imperial defence between the world wars, protecting an Empire knitted together by maritime communications. Underinvestment and the Washington treaties ensured that the navy would go to war on 1939 with an assortment of inadequate equipment, much of which dated back to the First World War. In the meantime the Axis powers systematically ignored and avoided the limits imposed upon them. The failure to modernise the Royal Navy had the clearest consequences for British possessions in the Far East. A vast new naval base was built at Singapore between the wars, but with no fleet to make use of it. It was planned that units would be moved from the Atlantic in the event of a war (with Japan), but when that war came in 1941 the navy was already totally tied down in the West fighting Germany's U-Boats and surface raiders and the Italian navy in the Mediterranean. The token force sent to Singapore, in a futile last minute attempt to deter the Japanese, was sunk in short order by aircraft off the coast of Malaya soon after the outbreak of hostilities. Without an overwhelmingly powerful naval deterrent Britain's overseas possessions were easy targets for its rivals.

While the maritime component, upon which Britain's power rested, was allowed to deteriorate plans for the next war with Germany were developed. Shockingly, the strategy for the second war was an almost direct re-run of the first. A protracted period of static fighting in France and Belgium, by Anglo-French armies, while the allies mobilised the resources to carry the war into Germany. The disastrous French campaign of 1940, and the evacuation at Dunkirk, put paid to British participation on the "central front" against the Wehrmacht in Europe until 1944. The Second World War thus, in reality, played out far less like the first and far more like the long struggle against Napoleon over a century earlier. The Royal Navy systematically seized control of the North Sea and Mediterranean, slowly defeating the Kriegsmarine's commerce raiding strategy, and denying the European Axis powers the ability to reach outside of the continent. Mussolini's ill considered North African adventure played out like Napoleon's. With Britain in control of the sea, Axis forces cut off from their logistics networks and their armies starved of supplies it was only a matter of time before they were forced to surrender.

As with Napoleon in 1812, in 1941 Hitler had nowhere else to go Except East into Russia. There his armies were systematically bled by bitter resistance and a hostile climate, before being smashed to pieces in a series of vast counter-offensives, that took Soviet armies to the gates of Berlin. Just as Russian armies had marched into Paris over a century earlier. Britain's contribution was not at all inconsequential, at a modest cost in lives the German state was denied use of the sea, the Soviets were bolstered in their fight against the Wehrmacht and the Luftwaffe was mauled over Britain, then defeated over Germany. Ironically the abject failure of Britain's continental strategy in 1940 allowed for a shift back to a more successful maritime strategy. Despite chronic under-investment before the war the Royal Navy proved it's fearsome reputation was not undeserved, and fought with all the skill and determination of its Napoleonic ancestor. As for the British army: from North Africa to Italy and France it was situated wherever the 'soft underbelly' of the Wehrmacht happened to be, fighting alongside continental allies it forced the Axis to divert vital resources away from the decisive theatre: the Eastern Front.

If the First World War was a Pyrrhic victory for Britain, the second was a catastrophe. While the country could be counted amongst the victors it was certainly not a winner. A third of its economic assets had been sacrificed  in the first war, and half of what remained in the second. The continental approach failed to bring victory in 1940, the Fall of France forced Britain to undertake an enormously expensive crash rearmament programme which required the large-scale conversion of civilian industry. This, along with other factors, would contribute to the steady decline of Britain as a competitive industrial power in the post-war world. By 1945 the country was enormously overstretched and financially exhausted. All the advantages that Britain had used to build her position in the world: maritime supremacy, strategic mobility and the precise application of force to achieve limited aims, had been sacrificed in pursuit of the continental armed forces presumed necessary to defend the homeland and the Empire. If the Second World War was, in significant part, fought to preserve Britain's position at the centre of an Imperial system, then the continental military strategy proved a spectacular failure.

In the post-war world the commitment to continental power continued unabated, despite its abject failure to advance British interests in two world wars. Britain retained its vast wartime conscript army long after the conclusion of the Second World War, in order to deal with new pressures from the European theatre of the emerging Cold War and decolonisation. By 1945 large land forces had become a permanent fixture in British defence planning, which imposed serious demands on an increasingly squeezed defence budget. Policing and relinquishing the vast land empire Britain had accrued over the course of the nineteenth century has also begun to take it's toll. Managed decolonisation proved to be a far more costly and manpower intensive business than the original conquests that had created the empire. At the height of the Malayan Emergency 40,000 commonwealth troops, the vast majority of whom were British, were tied down fighting the Communist insurgency there. A further 24,000 British soldiers and police tried unsuccessfully to suppress the Jewish insurgency in Palestine, until their withdrawal in 1947. Ten thousand regulars were required to combat the Mao Mao rebellion in Kenya, and thirty thousand were deployed to the colony of Aden at the peak of the conflict there. The list goes on but policing the empire, even when the process of decolonisation was well under way, became a major drain on Britain's military resources.

and move the country towards decolonisation and democratic rule.
Aside from colonial policing, the other continental commitment that stretched Britain's resources in the post-war world was the occupation of Germany and later the commitment to NATO. The British Army of the Rhine, and it's reinforcing forces, had nearly half the 316,000 soldiers in the army of 1960 assigned to it; with around 50,000 continuously forward deployed to Germany. Britain's commitment to the defence of Germany would steadily become an unhealthy fixation, a single narrow role was being conceived for the armed forces. As further economic pressures exerted themselves, the unchanging NATO commitment became a millstone around the country's neck. The needs of the Western alliance were always placed above the creation of mobile and flexible forces well suited to the defence of Britain's national interests outside of Europe. The weaknesses in Britain's maritime forces were already plain to see in the aftermath of the 1956 Suez war. Inadequacies in carrier air power, airbases ashore and sealift available at short notice would ensure that, by the time the preparatory bombing had been completed, the Anglo-French intervention force had lost the political initiative. The belated ground invasion that followed was cut short well before it achieved its objective: presenting the world with the fait accompli of an Anglo-French controlled canal zone. In the years that followed a declining defence budget, inter-service politics and the demands of a Eurocentric continental strategy would ensure that most of these deficiencies would never be properly addressed.

The withdrawal from East of Suez just over a decade later was as much about the prioritisation of the European theatre of operations as it was about the stated aim of cutting the cost of overseas bases. Proposals by the Royal Navy in the late 1950s suggested that the commitment could have been met by naval forces operating from a single large base (likely in Australia). Although this was ruled out on cost grounds, the navy's proposed "double stance" single-base concept would have required six large aircraft carriers, the more modest three carrier "single stance" Joint Services Seaborne Force (JSSF) proposal, operating from bases in Singapore and Bahrain, was both achievable and affordable. The JSSF concept envisaged a mobile and flexible medium-sized maritime intervention force to deliver the East of Suez commitment. Although parts of the idea, like the modernisation of Britain's amphibious shipping, were realised the overarching concept was steadily killed off by attacks by the other services in the second half of the 1960s. Notably the RAF's victory in the 1965-66 battle over the replacement of the conventional carriers, and the temporary success of their alternative "island strategy" before Britain's East of Suez role was officially abandoned altogether in 1968.

Operation Vantage, the UK response to the 1961 Kuwait crisis, proved just how effective flexible seaborne rapid reaction forces could be at nipping crises in the bud, before they could develop. It was a classic maritime response to a threat to British regional interests: a short, sharp, demonstration of force designed to achieve a limited objective, followed by withdrawal and the poising of forces offshore to cement the success of the initial action. However, the decision to withdraw from East of Suez bases, notably in Aden, Bahrain and Singapore, was as much about post-imperial retrenchment (and the idea that Britain's "new place in the world" was as a European power) as it was about the cost of maintaining those expensive facilities in the wake of the 1968 sterling crisis. Once again the choice to focus on a continental structure and role for the armed forces failed to support the UK's position as a global power, capable of projecting force in support of its interests. Instead of smaller but highly mobile maritime forces projected from a single large base East of Suez, the UK ended up with expensive and relatively immobile forces tied to a number of bases scattered across the region. In short: an increasingly unsustainable drain on resources with no European cold war role. Said maritime force could have been withdrawn to Europe in the event of a crisis, whereas comparatively immobile troops and land-based aircraft would have been considerably more difficult to redeploy at short notice.

With the end of National Service (conscription) in 1960 the stream of cheap manpower used to support Britain's array of overseas bases steadily began to dry up. As the process of decolonisation continued apace the army would shrink by half in less than twenty years, as the cost of manpower and equipment steadily rose throughout the 1960s and 70s. Even while spending a substantial proportion of it's national income on defence (between 1960 and 1980 it hovered around 5-6% of GDP) the country could not afford both a robust continental army and a globally deployable power projection navy. Throughout this period the government essentially "fudged" the issue by maintaining existing maritime forces left over from the rearmament programmes for the Second World War and Korea, but not replacing essential equipment like the conventional aircraft carriers (cut in 1966) when they reached the end of their lives. The government, and the new ministry of defence, initially attempted to cut a "middle way" between the continental and maritime spheres, that appeased the interests of all three services, which spectacularly unraveled in the late 1960s; as Britain abandoned its presence East of Suez, and left the defence of its interests there to the United States.

The incoherence of this policy was soon laid bare, after less than a decade away from the region the Royal Navy returned to the Arabian Gulf, to protect Britain's interests there and safeguard civilian shipping. In the long term the main consequences of "withdrawal" were the significant weakening Britain's regional influence, a major loss of military credibility and the abandonment of a handful of mostly useless bases (and two extremely useful ones in Bahrain and Singapore). Commitments to Southeast Asian stability (expressed after 1971 in the UK's membership of the Five Powers Defence Arrangements) could not be easily abandoned, nor could the UK extract itself from the commitments that derived from its dependence on Gulf oil.
Less than ten years after "withdrawal" the Royal Navy was back
East of Suez.
Slightly more than a decade after the last British troops were withdrawn from East of Suez, in which time defence policy had become focused on the continental confrontation with the Soviet Union in the European theater and the worsening situation in Northern Ireland, the unexpected happened. During the 1982 Falklands crisis, and the war that ensued, the fundamental assumptions upon which UK defence planning had rested for a decade came apart at the seams. The infamous 1981 defence white paper, overseen by then defence secretary John Nott, envisioned a severely limited role for the UK's maritime expeditionary forces. While the Royal Marines were to be retained, the two Fearless class amphibious ships were to be retired without replacement in 1982 and 1984. One of the three Invincible class light anti-submarine carriers would also be sold, as would the much older Centaur class carrier HMS Hermes. The review clearly prioritised Britain's continental commitment to NATO, with the Army and RAF both accepting a cut in manpower in exchange for new Challenger tanks, the retention of the F-4 Phantom, the introduction of the Tornado ADV fighter and the purchase of a fleet of new AV8B Harrier IIs. Fortunately for the United Kingdom, the Falklands crisis broke before the white paper's programme of changes could be fully implemented. The resulting conflict saw a British tri-service task force, similar in concept (if not in scale) to the JSSF envisaged in the early 1960s, sail half way around the world and recapture the islands from heavily entrenched Argentine forces. In 1982 maritime forces proved flexible, responsive and mobile enough to "go to the crisis" with sufficient force to decisively impact events on the ground.

It is also necessary to point out that the Falklands crisis, and the subsequent war, did not appear as a bolt from the blue. Argentina's intentions, and the need for a robust maritime force to deter attacks on Britain's scattered overseas territories, had been relatively obvious since their 1976 occupation of Southern Thule. It has been suggested by some that Operation Journeyman, the dispatch of a small naval task force the next year; in response to the occupation, may have deterred an earlier Argentine move to invade the Falklands proper. The position of the ministry of defence, their myopic focus on the European theatre and the Cold War, ensured the maritime power projection would be severely neglected. This happened to such an extent that it almost caused a military defeat, that would have had catastrophic effects on Britain's international standing. Even with the few legacy pieces of equipment like the amphibious ships and HMS Hermes the operation to retake the islands was, in the words of the ground force commander Major General Jeremy Moore, "a damn close run thing". It is a sobering thought that if the war had happened just two years later none of the legacy equipment, that proved critical to Britain's success, would have been available. The likelihood is that the operation probably wouldn't have even been attempted.
The two amphibious landing ships Fearless and Intrepid were vital to
Britain's military expedition to the Falklands. Both were slated for
disposal in 1982 and 1984 respectively.
While it is fair to say that the war in the South Atlantic saved elements of the UK's maritime force projection capability, it didn't initiate a significant change in national strategy. The overriding focus remained on the European continent, NATO and the Cold War. Unfortunately for defence planners all of this came crashing down, along with the Berlin Wall, in 1989. The collapse of the Soviet Union did not bring about "the end of history" as some optimistic commentators suggested at the time. Instead it ushered in a decade of instability in the former Communist bloc and further afield. The 1990s were not the "easy" decade for the West that they are now painted as. While the Cold War had furnished Europe and the United States with large and capable armed forces, they were often used to manage threats they had not been designed for. The decade was defined by ongoing and brutal conflicts in the Gulf and Balkans, both tied to the collapse of the Cold War world order. While the 1990-91 Gulf War would appear, on its face, to be a successful continental-style war that the British played a significant part in, in fact it was anything but. It is not difficult to see that the UK contribution of just under 54,000 soldiers, sailors and airmen pales in comparison to the ~700,000 deployed by the United States. The war was overwhelmingly an American show, with coalition forces mainly there to add legitimacy to UN-backed US action. In light of this Britain's contribution can be seen as militarily useful, but by no means essential, and, more than anything else, politically advantageous for the United States. Worse for the United Kingdom though were the glaring deficiencies in the Cold War continental army that the war exposed. In order to achieve "maximum deterrent value" the BAOR's combat service, support and logistics elements had been neglected in order to generate larger combat arms. What this meant in practice was that much of the British army's heavy combat equipment in Germany was unserviceable and very difficult to deploy. Government investigations into the conduct of the Gulf war revealed that BAOR's Challenger I availability in 1990 was only 23%, with the rest being under repair or out of service. While the British Army could rely on an established logistics system in the NATO area, to support its forward-deployed forces in Germany, no such system existed for long-range expeditionary operations. British forces famously had to ransack almost their entire BAOR stockpile in order to scrounge together the equipment and ammunition to put a single Division in the field in 1990. Even then, without the backing of the US logistics network it is doubtful that they could have been sustained in high intensity combat for very long.

In the years after the Falklands war the army examined and dismissed the Brigade level logistics structure, used by the Royal Marines to great success in 1982. Their contention was that it would impose the burden of providing additional supporting forces upon the BAOR. As the Gulf War showed, even if a direct copy of the Marines' approach was inappropriate, the Army's logistics were inadequate for the large expeditionary operations they found themselves conducting. By the end of the Cold War Britain had the worst of both worlds, a hollow and immobile continental army and a severely neglected power projection navy. The 1990 "options for change" review, instead of charting a new path for Britain's armed forces that would better suit the new geo-strategic environment, simply cut evenly across all three services to produce a "peace dividend". The army and RAF were not withdrawn from Germany, their mission complete, but instead lingered there as the reduced "British Forces Germany".
The logistics system designed to support the BAOR fighting in Germany
proved inadequate when those forces needed to be projected far from
their continental European bases.
The 1994 "front line first" review brought more mixed results. The ongoing conflict in the Balkans highlighted the need for robust intervention forces, and the amphibious sealift to move them. This helped persuade the government at the time to place orders for a dedicated helicopter carrier (which would eventually become HMS Ocean) and two new ships to replace the ageing Fearless class amphibious landing ships. However, at the same time deep cuts fell on the network of logistics and support structures. 17 depots were closed, and all three services suffered further manpower reductions.

Britain's contribution to peacekeeping and peacemaking in the former Yugoslavia throughout the 1990s stands as a good example of how small but mobile forces, capable of achieving limited goals, can effectively secure broad national interests. The Royal Navy spent the five years from 1991-1996 playing a leading role in first monitoring and later maritime interception operations in the Adriatic, enforcing the UN arms embargo on the conflict area. Despite there being around 400,000 people under arms in Bosnia alone between 1992 and 1995 the British contingent of the UN Protection Force (UNPROFOR), numbering only 8,000 troops at it's height in August 1995, was able to achieve significant results using limited coercive force and acting in close concert with diplomatic efforts. By attaining a succession of limited aims the international peacekeeping force was able to improve the situation on the ground with local peace deals, which steadily built momentum for an internationally enforced general ceasefire. At its absolute height, as part of the 80,000 strong international Implementation Force (IFOR) deployed in 1995 to enforce the peace, the UK contingent increased to just under 12,000 troops until IFOR was disbanded and replaced with the smaller Stabilisation Force (SFOR) at the end of 1996. Britain's contribution to the latter was just over 5,000 troops. While the war in Bosnia bore little similarity to Britain's past maritime operations on the TV screens of the public, in reality it carried all the hallmarks of an effective maritime intervention. The use of limited coercive force to achieve limited aims, the use of a naval blockade to starve the warring parties of military equipment, the use of military force as part of a carefully considered political strategy and larger-scale action conducted alongside continental allies.

Many of the lessons of fighting in Bosnia, and expeditionary warfare in general, formed the basis of significant structural changes to the armed forces laid out in the 1998 Strategic Defence Review. The creation of "Joint Rapid Reaction Forces". It specified the need for increased deployability and a focus on expeditionary duties for the army, with the planned addition of the logistic elements necessary to support two medium sized deployments simultaneously. The foundations were also laid for the eventual replacement of the Invincible class carriers with two new larger ships, what later became the CVF programme, and has now resulted in the two 70,000 ton ships of the Queen Elizabeth class. The SDR also laid the groundwork for the excellent Bay class auxiliary amphibious ships. The trade-off for the Royal Navy were small decreases in the number of escorts, submarines and a reduction in the planned fleet of minehunters; from 35, 12 and 25 to 32, 10 and 22 respectively. The number of Merlin anti-submarine helicopters was also curtailed at 44, with upgraded Lynx helicopters making up some of the shortfall.

Amidst all the technical detail of the 1998 review one thing was clear, it was the first sign of an major realignment of British defence strategy. Although a substantial portion of the army still resided in Germany the SDR laid out a shift towards forces tailored for mobility and limited maritime intervention. The army's airborne forces were merged to create a new formation, 16 Air Assault Brigade, that would be held at high readiness along with the Royal Marines of 3 Commando Brigade. The interventions in Kosovo and Sierra Leone in 1999 and 2000 proved that the new structure did indeed offer greater mobility and flexibility for intervention operations conducted at short notice. Maritime force projection, limited aims and operating alongside allies where necessary once again proved to be a winning combination for the UK.

And then 9/11 happened.

While it is easy to write at length on the less than stellar outcomes of the "Global War on Terror", launched by President George W. Bush in the wake of Al Qaeda's attacks on New York and Washington, I shall focus instead on the effects that the wars in Afghanistan and Iraq had on the British armed forces. While the initial interventions in both countries swiftly achieved their aims, the removal of the Taliban and Saddam Hussein from power, the British armed forces were steadily drawn into a pair of open ended "enduring stabilisation operations"/counter-insurgency wars with expansive aims; for which they were poorly prepared and inadequately equipped. Without an increase in the defence budget to fund these wars assets, programmes and capabilities not directly linked to supporting ongoing operations were neglected, cut or reduced. The Royal Navy suffered particularly harsh reductions, with the number of escorts reduced from thirty-two hulls in 2001 to nineteen in 2014 and the number of nuclear attack submarines falling from twelve to six. Important amphibious and utility shipping was also lost in 2010 with the sale of RFA Largs Bay to Australia and the mothballing of one of the Albion class LPDs. There was also the much publicised retirement of the carrier Ark Royal and the Harrier jump jet, effectively "gapping" UK carrier strike capability for a decade. For those that would argue the reductions were a result of the 2007/8 financial crisis, rather than a result of fighting two extremely expensive wars, seven of the thirteen escorts lost from 2001-2014 were retired without replacement before 2007, as were three of the five nuclear attack submarines. The retirement of Ark Royal in 2010 was a logical step, as the Harrier aircraft that made up her air group were heavily committed to the war Afghanistan and had been unavailable for serious carrier deployment for several years.

Sadly, for all the progress towards the more limited, mobile and maritime defence structure outlined in the 1998 review much of Britain's naval capacity was beggared on the altar of attempting to sustain an unsustainable tempo of operations. The army's withdrawal from Iraq in 2008, and subsequent "doubling down" on the Afghan mission, came because they were completely unprepared to conduct two large stabilisation operations simultaneously. Even solely focusing on Afghanistan the army weren't able to deploy enough troops to Helmand province to achieve the objectives they were set. It would eventually require the introduction of thousands of US Marines alongside the British contingent to begin to wrest areas away from the Taliban insurgents. While a culture of optimism, the famous "can-do" attitude of the British armed forces, prevailed at the top; a more sober analysis of the situation showed that these operations were unsustainable, unlikely to achieve the lofty aims set with the resources available and were doing serious damage to the UK's ability to conduct limited power projection operations.
The British Army never had the manpower or resources to sustain two large
enduring stabilisation operations.
Almost without exception the overriding lesson of the last hundred years, from the outbreak of the First World War in 1914 to the withdrawal from Afghanistan in 2014, is that Britain's adoption of a continental strategy failed to support the country's position in the world. Two bloody and ruinously expensive World Wars were followed by decades of colonial policing, retreat from parts of the world vital to UK national interests, an increasingly burdensome Cold War commitment to the defence of West Germany and finally two expensive and damaging counterinsurgency wars in Iraq and Afghanistan. We need to learn the lessons of our history, and of the last century, to see that this is; as Churchill put it "a game in which we are bound to lose". It is not difficult to recognise that the UK has the potential to generate extremely effective armed forces tailored to conduct limited maritime expeditionary warfare. It is plain to see that generating continental forces that are expensive enough to undermine the UK's power projection capabilities, but not large enough to effectively fight continental wars or defend Britain's national interests, is a foolish waste of resources.

The campaigns in Iraq and Afghanistan have been bruising experiences for the United Kingdom, seriously denting the prestige of the army and the confidence politicians have in the military's ability to provide solutions to complex problems. It would appear that now is the perfect time to once again espouse the benefits of a more limited and cautious maritime strategy for Britain. Thankfully the core strength of the Royal navy, while depleted, is far from broken. With new power projection equipment, not least the Queen Elizaebth class aircraft carriers, due to enter service soon; those at the top may begin to see what they've been missing for the last three and a half decades.

Those that advocate the strength of maritime strategy for the UK shouldn't get too carried away, the argument is far from won and there will be those that vehemently disagree. Although the 2015 Strategic Defence and Security Review appears to shift the focus back to a more maritime, limited and expeditionary focus it remains to be seen if it really has heralded a real shift in Britain's national strategy or if, like the 1998 review, it will promise much change but in practice deliver more continental military entanglements. Until we know for sure where this new direction will take us we should always look to our recent history, and ask the question: "Why should we sacrifice a game in which we are sure to win to play a game in which we are bound to lose?"

Queens and Princes: The Road Ahead for UK Carrier Aviation


 "The navy of any great power has the dream to have one or more aircraft carriers. The question is not whether you have an aircraft carrier, but what you do with your aircraft carrier."
- Major General Qian Lihua, director of the Chinese Defense Ministry's Foreign Affairs Office.

As it stands the UK is currently in the middle of a long process, which will culminate in the regeneration of key national capability: the ability to fly fixed wing aircraft from the decks of its carriers. Once this process is complete, some time in the early 2020s, the Royal Navy will return to operating full size carriers for the first time since Ark Royal, the last of the Audacious class, decommissioned in 1979. The new Queen Elizabeth class are true supercarriers, though not cast from the same mold as the US Navy's current Nimitz and Gerald R. Ford classes, they can still employ an impressive array of fixed and rotary wing aircraft. Although the class will be fitted with deck equipment for short take off and vertical landing (STOVL) aircraft like the F-35B, including the famous "ski-jump", they are of a similar size to the US Navy's former Forrestal and Kitty Hawk class carriers. It is easy to see that there is vast scope for modification and upgrade throughout their service lives, a process which every previous class of British carriers since the Second World War has undergone. The only certain thing is that these ships will end their service lives looking very different from the way they began them. Thankfully, unlike their predecessors, significant margins for growth have been built into the two ~70,000 ton ships from the start.

The short term shape of the carriers and their air groups is now mostly known, with the 2015 SDSR clearing up some of the speculation; especially with regards to the number of F-35B to be routinely embarked. The purchase of 42 airframes, with the specified purpose of arming the carriers with a "full air group", indicates that we could see the Tailored Air Group (TAG) routinely including an F-35B squadron; with a total of around 24 fixed-wing aircraft. This leaves a further 16 "slots" in the TAG available for a range of rotary wing assets, including the Army's Apache and the RAF operated Chinook. This is one of the most pioneering parts of the UK carrier concept: operating them as RN-led tri service assets. In theory these ships could simultaneously host RAF, Fleet Air Arm and Army Air Corps aircraft and maintainance crews. Making all this work in practice, in a challenging maritime environment, is likely to be a major test of the viability of the concept. It is encouraging that the tri service concept builds upon years of hard won experience, gained from the RAF/FAA Joint Force Harrier and the RAF/FAA/AAC Joint Helicopter Command. Small numbers of RAF Harriers have, in the past, operated from the decks of RN light carriers. As recently as 2011 the AAC flew some of its Apache gunships from HMS Ocean during the intervention in Libya. However, the scale of the Queen Elizabeth carriers and the sheer number of aircraft operating from her will inevitably complicate matters. Nevertheless, the concept is certainly exciting and will give the UK a truly flexible asset and a first class capability, if they can pull it off.

So, what might the future hold for these ships, the aircraft that fly from them and the people that will make the whole thing work?

"Jointness" and the Joint Strike Fighter:
As it stands the medium-term plan for the UK's fleet of F-35B Joint Strike Fighters has been spelled out. With the initial aircraft divided between the RAF's 617 "Dambusters" Sqdn. and the FAA's 809 "Immortals" Sqdn. Both of which will be based at RAF Marham in Norfolk, the UK hub for F-35. The pilots and maintainers in both squadrons will be a mix of RAF and FAA personnel, with the bulk likely being drawn from the RAF. The entirety of the UK F-35 fleet will also be officially "owned" by the RAF, this means that the RN will have a more limited degree of control over the FAA badged squadrons than in the past. Looking to history for a precedent for this sort of arrangement seems to throw up an eventual outcome that doesn't bode well for the current structure. Between 1924 and 1937 UK naval aviation was given over to a branch of the RAF, over the ensuing thirteen years a clear divide emerged between the naval aviators and their land based counterparts. While "FAA squadrons" will exist in the future structure they will, in effect, function as a naval branch of the RAF in all but name. Squadrons routinely deployed to the carriers, likely the FAA badged ones, will develop a more "naval mentality" and slowly diverge in skills and attitudes from those that do so far less frequently or not at all. While the planned common pool of pilots may seem like a way around this, it may in fact end up militating against the development of the skilled naval aviators necessary to get the most from the carriers.

Allowing some pilots, wearing light or dark blue uniforms, to spend much of their career conducting carrier operations at sea will eventually result in the slow re-emergence of a group of professional naval aviators that will not fit especially comfortably into the planned joint structure. The same could be said of the ground crews and maintainers, with certain people gravitating towards the naval environment and drafts on the carriers while others remain ashore. Whether this will eventually lead to a natural split in the joint force, with the navy taking control of some of the aircraft once the FAA rebuilds the necessary skills and personnel base to do so, remains to be seen. Although the cost of doing so for the RN will likely remain prohibitive. What is very much more likely is that de-facto divisions will emerge within the joint force, with the FAA badged squadrons containing the preponderance of experienced carrier pilots and "navalised" maintainers. The land-based squadrons' pilots will continue to qualify for carrier operations, but will likely spend less time at sea building up to the same levels of practical experience as their counterparts in the naval squadrons.

Future of the air group:
The range of aircraft due to be flown from the decks of the Queen Elizabeth carriers in the medium-term is already clear at this point. The core of any TAG is always likely to be a number of F-35B to cover carrier air defence, strike and combat ISTAR. The number will vary depending on the task at hand, but I would think the ship would routinely deploy with a minimum of 12 on board-maintaining core naval aviation skills, providing CAP for the carrier group and allowing the ship to rapidly re-role for basic strike operations at very short notice. In the "maximum effort" scenario where both decks are in action simultaneously, with one acting as an enlarged LPH and the other a full strike carrier, I would still expect to see F-35B operating from both ships.
Merlin will form the second part of the core TAG, whether carrying the "Crowsnest" Airborne Early Warning (AEW) equipment, Anti Submarine Warfare (ASW) gear or in the HC3/4 cargo and troop transport configuration. What is reasonably certain is that Merlin, especially in the "Crowsnest" configuration, will nearly always be present aboard these ships.
The RN's Wildcats will also likely be a regular feature covering the surveillance, utility and surface strike (with the new Sea Venom lightweight anti-ship missile) roles. However, the limited number of airframes in RN service and high demand for the aircraft from other parts of the fleet, especially the forward-deployed escorts, may stand in the way of a regular presence on the carriers. The same case could be made for the ASW variant of the Merlin, the HM.2, with only 18 front-line airframes available to cover the needs of the escort fleet and the carriers. With regards to Wildcat best use of the tri service operations concept should be made by looking at close co-operation with the AAC, exploiting the possibility of routinely hosting of a number of Army Wildcats to ease the strain on the RN's fleet. This would also have the benefit of building and then sustaining the skills base necessary to rapidly and effectively embark and integrate Army helicopters and AAC crews at short notice if necessary.

Outside the core component aircraft of the TAG the carriers are also likely to see Army Apaches and RAF Chinooks embarked occasionally, on a less frequent basis. In order to operate these aircraft effectively from the carriers, pilots and aircraft will need to be exposed to the demands of operating in the maritime environment on a semi-regular basis. Similarly the ship-side aircraft handlers will need to build and maintain their experience dealing with very large helicopters such as Chinook. While it is helpful that both Apache and Chinook have already been deployed at sea, aboard HMS Ocean, the scale and tempo of deck operations aboard a carrier that will be simultaneously operating large numbers of helicopters and fixed wing aircraft will be very different. The RN is lucky that the basic needs of carrier operations, folding rotor blades and protection from salt corrosion, have already been built into the British Apaches. However, while Chinook does have the necessary corrosion resistance it lacks folding main rotors. Although the carriers' aircraft lifts have been designed to handle Chinook without folding blades these aircraft will take up a great deal of space in the hangar without them. This is acceptable if Chinook is only intermittently embarked for specific tasks. However, if it becomes a regular part of the air group then upgrading some or all of the Chinook fleet with powered folding rotors, or exploiting the unpowered folding mechanism already present, should be a high priority.

Looking slightly ahead into the next decade a single V-22 Osprey squadron should, if the money becomes available, be given serious consideration. The range of F-35B is already the shortest of all three variants, with forced loiter times an inherent part of carrier operations, air to air refueling (AAR) would be a very valuable support capability. The V-22 Aerial Refueling System (VARS) is a palletised probe and drogue tanking kit already in development for the US Marine Corps, for use with their F-35Bs. VARS initial operating capability is expected to be reached in 2017, so the system would be substantially de-risked in the event of a UK buy in the 2020s. While introducing a whole new aircraft and its supply chain into UK service would be costly, V-22 and VARS is the only realistic option open that is compatible with a STOVL carrier. With 16 airframes, for a squadron of 12 and a reserve of four, and eight VARS kits the UK could provide a continuous AAR capability for both carriers in the "maximum effort" scenario. The spare aircraft could also be flown from bases ashore to provide additional refueling capacity alongside the Voyager fleet during routine carrier operations, where only a single ship will be at sea. Of course, because VARS is a palletised kit, some of the aircraft could also be used in the heavy lift and troop transport roles for which they were originally designed; freeing up RAF Chinooks for operations ashore. The Osprey would also be able to cover most of what the US Navy calls the "Carrier Onboard Delivery" (COD) role, moving personnel and stores long distances from ship to shore and vice versa. Although the V-22 lacks the cargo space to carry the Pratt & Whitney F-135 engine for the F-35, it's range and carrying capacity are still impressive. It seems to be the case anyway that in RN service the spare engines will be carried by the accompanying MARS solid support ship: able to transfer them to the carrier via their heavy RAS gear when needed. So the Osprey's lack of capability in that area wouldn't be a severe drawback. Overall the V-22 would be a very useful option to add to the Queen Elizabeth carriers' TAG if, in future, the money becomes available.

Another interesting area for future development will be the operation of short takeoff and landing drones. A number of the current generation of propeller-driven long endurance UAVs operate at low enough speeds to consider carrier operations without catapults a serious proposition. A naval version of the Watchkeeper surveillance drone, or simply using some of the Army's could be one possibility for an initial round of trials to prove the concept. If successful, it could pave the way for trials with larger UAVs such as Predator, possibly using a simple pneumatic catapult for launch. All this is, however, a long way off. Although proving the concept and clearing the carriers to operate larger surveillance drones than the RN's ScanEagle would certainly be something to investigate and develop in the medium term.

Overall, by the time the Queen Elizabeth carriers reach their full operating capability in the mid-2020s the RN will have a pair of very capable ships with robust air groups, able to be tailored to suit specific missions. While the phrase "second only to the United States" is so often repeated by MoD and government officials that it's become a bit of a cliché, the capability offered by the Queen Elizabeths will almost certainly live up to those ambitious words. There are ways that this impressive capability could be further enhanced, with V-22 for AAR, heavy lift and COD, and grown over time by trialing UAVs; with a view to eventually including them in the array of aircraft that can be operated from the carriers' decks. If the TAG concept is properly implemented and a variety of aircraft from the RAF, FAA and AAC are routinely embarked for training in the maritime environment then these ships will deliver on the impressive flexibility they were designed to offer.

Operating both carriers:
SDSR 2015 delivered the pledge that the UK would operate both ships simultaneously to ensure one carrier will always be available for deployment 24/7/365. What this will mean in practice is that most of the time one ship will be alongside in the UK, usually undergoing repairs or a refit, while the other acts as the duty carrier: available to respond to events and deploy at short notice. However, as the RN discovered with its previous carriers, leaving ships alongside with minimal manning for prolonged periods of time leads to steady material deterioration and shortens the lives of the ships. Both Invincible and Ark Royal fell afoul of this, spending significant time unmanned and alongside in 3 Basin badly effected the material state of both ships. With only two Queen Elizabeth carriers available the RN cannot afford to make the same mistake, effectively mothballing one ship at a time for lack of crew will shorten the life of a class that could, given adequate care, serve for half a century. Failure to properly man and service both ships at all times would inevitably impose avoidable maintenance costs further down the line and steadily erode the RN's ability to surge two carriers as a "maximum effort" as a serious war fighting contingency against a near-peer opponent.

It has been said elsewhere but the 2020 SDSR needs to include a substantial increase in RN manpower, to enable the service to adequately crew both ships at all times and surge two carrier decks in an emergency: provided the spare ship isn't in deep refit. Providing adequate crew for both ships would also introduce additional opportunities for training in or near UK waters. The need to provide the RAF and AAC pilots and maintainers with experience of operating in the maritime environment has already been mentioned. With only one carrier deck operating at any time, which may be away on operations, the limited availability of a ship for the component elements of the TAG to train on is concerning. The flexible TAG concept only works if its constituent elements can be called upon at short-notice to form a mission-specific package. While the mock carrier at RNAS Culdrose will be a useful facility for training pilots in deck operations, it is no substitute for realistic training at sea. With a sufficiently manned second ship the RN could, when the ship is available, use the reserve carrier for training around the UK. Employing the Queen Elizabeths in this way ensures that the RN would always have more than enough ship-side crew to keep the duty carrier at full strength, and enough to make the two carrier "maximum effort" a realistic prospect. In order to achieve this though, the RN's total manpower must rise.

CATOBAR:
Finally, the thorny issue of whether these ships will ever be reconfigured and refitted with catapults and arrestor wires needs addressing. In 2012 the Coalition government looked at the costs of converting both ships, briefly committing to the cat & trap configuration, before reverting to the original STOVL configuration once it became clear that the costs of conversion would be prohibitive. The cost of converting the partially built Prince of Wales was stated to be an additional £2bn, while the class was supposed to be relatively easy to change from STOVL to CATOBAR in reality this does not seem to be the case. Some sources stated at the time the decision was reversed that conversion would have required modifications to over 200 compartments. A mid-life conversion may become necessary if there is no available STOVL replacement for F-35B after its 2045 out of service date. With so many unknowns inherent in predicting what could happen thirty years into the future, all that can be done is to restate much of what we already know.

A CATOBAR conversion would be extremely expensive, it would involve very extensive rebuilds of the ships and the generation of a whole new set of training pipelines for pilots, flight controllers and deck crew. It would also mean learning a whole new way of doing things, and it could not be done cheaply or quickly. When all is said and done developing a bespoke UK STOVL aircraft to replace the F-35B might actually end up being the cheaper option, when compared with the cost of the substantial organisational changes that would be necessary. While many long time supporters of the Royal Navy's cause would, no doubt, love to see the UK return to catapult carrier operations the reality is that STOVL currently offers an effective capability at a tolerable cost. In the author's opinion the decision to convert to CATOBAR would only be taken if there was no other alternative, including the development of a bespoke UK STOVL aircraft. The hope at this point should be that the USMC continues to make a convincing case for STOVL aviation within the US armed forces and ultimately gets a like for like F-35B replacement. This would enable the UK to participate in a joint or multilateral programme, with orders large enough to drive down the unit cost. It must be stated again though that predicting the shape of UK naval aviation that far into the future is almost impossible. For all the sentimental and symbolic importance attached to CATOBAR, it is clear at this point that while a mid-life conversion would be possible, it is far from preferable.

Almost from their very inception the Queen Elizabeth class carriers have proved be a subject of controversy. Fierce and sometimes public debates have been held on their relevance in the modern world, usefulness for the UK and the difficulties involved in realising their potential capabilities in practice. The last point was expressed with a clarity that only tabloid journalism could manage in the oft-repeated phrase "carriers with no aircraft". Thankfully, it is now clear that the tabloids were wrong and the public's concern was partly misplaced, the carriers will have a robust TAG with a great deal of potential flexibility and, if necessary, striking power. While there is still a little room for improvement with regards to the air group such as the inclusion of an AAR tanker, Osprey VARS or otherwise, the concept is sound and the aircraft will be available to start realising it by the early-mid 2020s. While the author still has concerns over the long-term durability of the Joint RAF/FAA F-35B arrangement it is certainly a workable plan and may yet prove to be a success. The key to successfully realising the high-minded goal of turning the carriers into tri service aviation ships will be regular joint training for all component parts of the TAG, on the mock carrier deck at RNAS Culdrose but, more importantly: at sea. Without experience and training on a real carrier deck the individual TAG components will likely struggle to adapt to a very different working environment whilst also trying to conduct operations. The old adage train how you fight comes to mind, if we intend to embark RAF Chinooks and F-35s or AAC Apaches and Wildcats then they must spend regular time training aboard one of the carriers. In order to achieve this the RN needs to be given the manpower to operate both carriers simultaneously as often as repair and refit schedules will permit, with the off-duty carrier operating near the UK as a training platform. This would have the added benefit of keeping both ships out of what would effectively be time spent in mothballs: alongside in Portsmouth with a caretaker crew aboard, which shortened the lives of the preceding Invincible class. If the UK intends to make good on it's substantial investment in the Queen Elizabeth carriers they need to be manned sufficiently to maintain them over their 40-50 year lifespan, failure to do so would be yet another example of the MoD being "penny wise and pound foolish".
Finally, while a post-F-35B conversion to the catapult and arrestor wire configuration is theoretically possible, the costs of doing so, and the institutional upheaval it would cause, would be enormous. In the end, despite the emotional pull exerted by the idea of "proper" carriers and the drama of catapult operations, a CATOBAR conversion should only be embarked upon if the only other alternative is scrapping the ships prematurely and wasting the money already sunk into them.

While some commentators have been very dismissive of the UK carrier programme in the author's opinion they could, in time, give the UK a truly first-class capability "second only to the United States". However, in order to achieve that ambitious and, let's not forget, thoroughly attainable goal the UK needs to make good on its current investment in the carriers. This can be achieved by manning and operating both, potentially investing in AAR capability and most importantly ensuring all component parts of the TAG regularly embark and train on the carriers. At the close I will return to the words of Major General Lihua:

 "The question is not whether you have an aircraft carrier, but what you do with your aircraft carrier."
