between the Lockheed Martin 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. In 2007, the Ministry of Defence confirmed its order for two Queen Elizabeth-class aircraft carriers. Technology transfer The UK has invested 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 US Congressman Henry Hyde because of his concern about potential technology transfer to third countries. 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." In February 2006 the chairman of the Commons Defence Select Committee stated that unless the UK got "all the information and technology it requires to maintain and upgrade the aircraft independently.... [it] might have to consider whether to continue in the programme. Lord Drayson, Minister for Defence Procurement, while on a government visit to Washington to speak to members of Congress stated "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. 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." 2010 Strategic Defence and Security Review As part of the 2010 Strategic Defence and Security Review, it was announced that the previous intention to order 138 STOVL F-35Bs had been changed to a smaller number of CATOBAR F-35Cs, with the anticipated entry
