The Joint Combat Aircraft (JCA) is the official designation of the United Kingdom Ministry of Defence used for the F-35 Lightning II, formerly the Joint Strike Fighter, and the result of the Joint Strike Fighter Program.

Programme historyEdit

The JCA programme began in 1996 as the Future Carrier Borne Aircraft (FCBA), a replacement for the Royal Navy's Sea Harrier intended for operation from the RN's CVFs. The requirement for the FCBA was set out in Staff Target 6464 which specified a carrier-borne aircraft capable of air defence of naval and ground forces and self-escorting ground attack.

As the Royal Navy version of the JCA (and potentially Royal Air Force versions) would operate from the two newly ordered Queen Elizabeth Class aircraft carriers, the selection of the aircraft was closely linked to the design of the carrier. Candidates for the JCA were thus listed by carrier type:

Following the 1998 Strategic Defence Review the Navy's Harrier FA.2s and RAF Harrier GR.7s were merged to form Joint Force 2000 (later Joint Force Harrier. As such the requirement was revised to include the replacement of the RAF Harrier force; this led to the renaming of the project as the Future Joint Combat Aircraft (FJCA) in 2001. Later, in the third and final name change of the project, the word "future" was removed.

Aircraft selectionEdit

On 17 January 2001 the UK signed a Memorandum of Understanding (MoU) with the U.S. Department of Defense for full participation in the Joint Strike Fighter project, confirming the JSF as the JCA. This gave the UK significant input into aircraft design and the choice between the Lockheed X-35 and Boeing X-32. On 26 October 2001 the DoD announced that Lockheed Martin had won the JSF contract.

On 30 September 2002 the MoD announced that the Royal Navy and RAF will operate the STOVL F-35B variant. At the same time it was announced that the carriers would take the form of large, conventional carriers, which will be adapted for STOVL operations. The carriers, expected to remain in service for 50 years, will be convertible to CATOBAR operations for the generation of aircraft after the F-35 JCA.

In 2007, the Ministry of Defence confirmed its order for two Queen Elizabeth class aircraft carriers, to enter Royal Navy service in 2015-2018.

Technology transferEdit

The UK has invested US$2 billion (GBP £1.08 billion) in development funding for the JSF. Britain has also worked for five years for an ITAR waiver to allow greater technology transfer associated with the project. The effort, backed by the Bush administration, has been repeatedly blocked by U.S. Congressman Henry Hyde because of his concern about potential technology transfer to third countries.[1] On Friday 27 May 2006 President Bush and Prime Minister Tony Blair issued a joint statement which announced:

"Both governments agree that the UK will have the ability to successfully operate, upgrade, employ, and maintain the Joint Strike Fighter such that the UK retains operational sovereignty over the aircraft."[2]

The CEO of BAE Systems Mike Turner, the British contractor on the plane, had complained that the U.S. has not given the UK (and his company) access to the crucial source code of the plane's software, thus making it impossible for the UK to maintain and modify the JSF independently. On 21 December 2005 an article was published in the The Herald saying that MPs viewed as "unacceptable" the U.S. refusal to grant access to the source code. The article quoted the chairman of the Commons Defence Select Committee as saying that unless the UK receives assurances of access to the software information, "the UK might have to consider whether to continue in the programme".[3]

Following on from this Lord Drayson, Minister for Defence Procurement, while on a government visit to Washington to speak to members of Congress, took a firmer stance. He was quoted as saying, "We do expect [the software] technology transfer to take place. But if it does not take place we will not be able to purchase these aircraft", and has mentioned that there is a 'plan B' if the deal falls through.[4] A suggested likely option was the development of a navalised Typhoon. Mike Turner has said it was not what he recommend, but:

"as Lord Drayson has made clear, there needs to be a fall-back in case something goes wrong.[5]

A navalised Typhoon may have required the RN's Queen Elizabeth class aircraft carriers to be built with catapults, adding to their cost and capability.

BasingEdit

In November 2005 it was announced that the F-35 main base will be RAF Lossiemouth, Scotland. Seven other sites were considered; RAF Marham, RAF St. Mawgan, RAF Cottesmore, RAF Wittering, RNAS Yeovilton, RAF Leeming and RAF Kinloss. Lossiemouth was selected due its existing facilities and access to training areas.[6]
