CVA-01
CVA-01 was a proposed United Kingdom aircraft carrier, designed during the 1960s. The ship was intended to be the first of a class that would replace all then-existing Royal Navy carriers, most of which had been designed before or during the Second World War. CVA-01 and CVA-02 were intended to replace and , while CVA-03 and CVA-04 would have replaced and respectively. The planned four carrier class was soon reduced to three before further being reduced to two and finally, following a government review, in the form of the 1966 Defence White Paper, the project was cancelled, along with  the proposed Type 82 destroyer class, which were intended primarily as escorts for carrier groups. Factors contributing to the cancellation of CVA-01 included inter-service rivalries, the huge costs of the proposed carrier, and the technical complexity and difficulties it would have presented in construction, operation, and maintenance. Had CVA-01 class been built, it is likely they would have been named HMS "Queen Elizabeth", HMS "Duke of Edinburgh", HMS "Prince of Wales" and HMS "Princess Royal" respectively. Origin. In the 1960s, the Royal Navy was still one of the premier carrier fleets in the world, second only to the US  Navy, which was in the process of building the 80,000-ton s. The British fleet included the fleet carriers and , and two smaller carriers, the completely reconstructed , and the somewhat newer light carrier , both with 3D Type 984 radar and C3, but limited to air groups of 25 aircraft: at the most 20 fighters and strike aircraft and five helicopters, or alternately 16 fighters and strike aircraft, four turboprop Fairey Gannet AEW, and five helicopters. A fifth carrier, , was modernised to the minimum standard to operate second-generation Scimitars and Vixens in 1959, but was never satisfactory or safe for  operating nuclear strike aircraft and was a purely interim capability while "Eagle" was refitting. While all four of the Navy's large carriers were capable of operating the S.2 version of the Blackburn Buccaneer strike aircraft, only "Ark Royal" and "Eagle" were realistically big enough to accommodate both a squadron of Buccaneers (up to 14 aircraft) and a squadron of F-4 Phantoms, which the Royal Navy intended to procure as its new fleet air defence aircraft. With the remainder of the air group this would give a total of approximately 40 aircraft, which compared poorly to the 90 available to  a "Kitty Hawk"-class ship. The increasing weight and size of modern jet fighters meant that a larger deck area was required for takeoffs and landings. Although the Royal Navy had come up with increasingly innovative ways to allow ever-larger aircraft to operate from the small flight decks of their carriers, the limited physical life left in the existing ships (only "Hermes" was considered capable of reliable and efficient extension past 1975), and the inability of both "Victorious" and "Hermes", the most effectively and expensively modernised of the carriers, to operate the F-4 or an effective and useful number of  Buccaneers, made the order of at least two new large fleet carriers essential by the mid-1960s. Design. Considerations. Once the Chiefs of Staff had given their approval to the idea of new carriers being necessary, in January 1962 in the strategic paper COS(621)1 "British Strategy in the Sixties", the Admiralty Board had to sift through six possible designs. These ranged from 42,000 to 68,000 tons at full load. The largest design, based on the American , had space for four full-sized steam catapults, but was rejected early on as being significantly too costly, particularly in terms of the dockyard upgrades  that would be needed to service them. The advantages of size were immediately apparent; a 42,000-ton carrier could only hold 27 aircraft, while a 55,000-ton carrier could carry 49. This was an 80% increase in the size of the airgroup for a 30% increase in displacement. Even with these smaller designs, cost was a serious issue. The Treasury and the Air Ministry were pushing for a new set of long-range strike aircraft operating from a string of bases around the globe. For the former this appeared a cost-effective solution for the East of Suez issue, and  for the latter it meant that the Royal Navy would not get a majority of the defence budget. As a result, by July 1963 it was announced that only one carrier would be built. Details. The CVA-01 would have displaced no more than 54,500 tons, with a flight deck length (including the bridle arrester boom) of . The size of the flight deck, combined with steam catapults and arrester gear, would have enabled the carriers to operate the latest jets. The aircraft complement would have been a mix of 36 F-4 Phantom II fleet defence fighter (with secondary strike role) and  Blackburn Buccaneer low-level strike aircraft, four early-warning aircraft, five anti-submarine helicopters and two search-and-rescue helicopters. The steam plant was a novel design as was the electrical distribution system. The large 'Broomstick' radar dome above the central island on the carrier was planned to be a Type 988 Anglo-Dutch 3D radar, which would subsequently be fitted on the Royal Netherlands Navy s, although this would not have been fitted to the final carrier as Britain pulled out of the project. Cancellation. By early 1963 the Minister of Defence Peter Thorneycroft announced in Parliament that one  new aircraft carrier would be built, at an estimated cost of £56 million, although the Treasury thought that the final cost was likely to be nearer £100 million. This was based on the carrier using the same aircraft as the Royal Air Force, the Hawker Siddeley P.1154 supersonic V/STOL aircraft (a larger version of what would become the Hawker Siddeley Harrier). After the General Election of October 1964, however, the new Labour Government wanted to cut back defence spending, and the RAF attacked the Royal Navy's carrier in an attempt to safeguard first its BAC TSR-2  strike/reconnaissance aircraft and then its proposed replacement, the General Dynamics F-111, from the cuts. The new government, and by extension the Treasury, were particularly concerned about the size issues involved, as these were fluctuating quite frequently. They therefore demanded that the Admiralty keep to 53,000 tons. With the navy unwilling to alter the size of the carrier and its airgroup accordingly the difficulties spiralled, and the final tonnage was much more likely to be nearer 55,000 tons. The design issues also increased, including dramatically reduced top speed, deck space, armour and radar equipment. When the Cabinet met in February  1966, the new Secretary of State for Defence, Denis Healey, strongly supported the RAF and their plan for long-range strike aircraft, by now the F-111, partially due to the cost issues of running fleet carriers, and partially due to opposition to a strong British military. This meeting resulted in the 1966 Defence White Paper. In this paper the CVA-01 was finally cancelled, along with the remainder of the Type 82 destroyers that would have been built as escorts, of which only was eventually completed. Instead plans were made for the modernisation of "Eagle" and "Ark Royal". The final chief  designer of CVA-01 said that by the time project was cancelled, so many design compromises had been made because of size and budget restrictions, that the whole project had become risky. The following year, a supplement to the review marked the ending of a global presence with the withdrawal of British presence "East of Suez". The year after, the purchase of F-111s was cancelled. One argument about the cancellation of CVA-01 states that the RAF moved Australia by 500 miles in its documents to support the air force's preferred strategy of land-based aircraft. Regardless of the story's  veracity, the principal reason for the cancellation was that the Defence Review board believed adequate cover could be better provided East of Suez by RAF strike aircraft flying from bases in Australia and uninhabited islands in the Indian Ocean, rather than by a small carrier fleet in the 1970s which would have still included "Hermes". The Review asserted the carrier's only effective use was to project British power East of Suez, and that the RN carriers were too 'vulnerable' for the RN's other major theatre in the North Atlantic. When the British government later decided in 1967 that  it would withdraw from east of Suez, the case for carriers weakened further. The 1966 Review stated that the ability of RAF to cover 300 miles offshore was enough for the 1970s, regardless of the RAF's contested claim to be able to provide air cover out to 700 miles. The cancellation of 150 TSR2 aircraft by Labour in mid-1965 was the basis of the RAF's argument for the 'island hopping strategy'. Subsequent Royal Navy carriers. Section::::"Eagle" and "Ark Royal". The cancellation of CVA-01 was planned to be compensated for by the minimum updating of both "Eagle" and "Ark  Royal" to enable them to operate the 52 Phantoms ordered. However, a decision was taken later to completely phase out fixed-wing flying in the Royal Navy by 1972 in line with withdrawal from "East of Suez". "Victorious" was withdrawn in 1969 and "Hermes" was converted to a "commando carrier" to replace her sister "Albion", in 1971-73. At the time of the announcement, "Ark Royal" was beginning a reconstruction with an austere refit of radar systems, communications, partial electrical rewiring and fittings needed to allow operation of the Phantom (despite the fact that it was a worse base for  such a conversion than "Eagle"), and it was deemed unacceptable either to cancel the much needed work, or to spend such a large amount of money (approx. £32m) for less than three years continued use. A change of government led, as a consequence, to retain "Ark Royal" following her 1967–1970 refit, but not to proceed with a refit of "Eagle". "Eagle" was decommissioned in 1972, partly due to damage inflicted in a partial grounding a year before; repairs would have probably required a minimum 18-month refit in 1972–1973 at a cost of around £40 million to  operate till 1977. Many of the second squadron of F-4 Phantoms intended for "Eagle" were immediately transferred to the RAF. "Eagle" remained officially in reserve as a source of spares to maintain "Ark Royal" until 1978, but could never have been brought back into service. Section::::"Through Deck Cruiser". The Royal Navy did not however completely surrender aircraft carrier capability, despite the eventual withdrawal of "Ark Royal" in 1978. The concept of the "through-deck command cruiser" was first raised in the late 1960s, when it became clear that there was a good chance of the Fleet Air Arm losing fixed -wing capability. The "through-deck cruiser" name was chosen to avoid the stigma of great expense attached to full-size aircraft carriers, with these 20,000 ton ships having significantly less fixed-wing aviation capability than the planned CVA-01 carriers. However, they were to function as part of combined NATO fleets, with a primary mission of providing Cold War anti-submarine patrols in the north-east Atlantic Ocean, in support of the American carrier battle groups. In order to ensure the safety of the battle group around the "cruiser", the facility to carry the Sea Harrier was added at a late  stage of development, the intention being that it could give the battle group the capability to intercept Soviet aircraft without having to rely either on land based or US Navy interceptors. The ultimate result of this was the Royal Navy being able to deploy carrier-based aircraft during the Falklands War. One officer who worked on the CVA-01 believed, however, that had the United Kingdom "built two or three ships to this design, they would now [in 1999] be seen to have been the bargain of the century and they would have made the Falklands War a much less risky  operation" due to greater functionality. CVF. The United Kingdom returned to the fleet carrier idea with the construction of the Queen Elizabeth-class aircraft carriers, which are larger than the cancelled CVA-01s. The two new carriers, initially dubbed CVF (F for 'Future'), are named and . The contract for these vessels was announced on 25 July 2007 by the Secretary of State for Defence Des Browne. Following "Queen Elizabeth"'s commissioning on 7 December 2017, "Prince of Wales" was commissioned on 10 December 2019.
