The McDonnell Douglas (now Boeing) T-45 Goshawk is a highly modified version of the British BAE Systems Hawk land-based training jet aircraft. Manufactured by McDonnell Douglas (now Boeing) and British Aerospace (now BAE Systems), the T-45 is used by the United States Navy as an aircraft carrier-capable trainer. The T-45 Goshawk has its origins in the mid-1970s, during which time the U.S. Navy formally commenced its search for a new jet trainer aircraft to serve as a single replacement for both its T-2 Buckeye and A-4 Skyhawk trainers. During 1978, the VTXTS advanced trainer program to meet this need was formally launched by the U.S. Navy. An Anglo-American team, comprising British aviation manufacturer British Aerospace (BAe) and American aircraft company McDonnell Douglas (MDC), decided to submit their proposal for a navalised version of BAe's land-based Hawk trainer. Other manufacturers also submitted bids, such as a rival team of French aircraft company Dassault Aviation, German manufacturer Dornier and American aerospace company Lockheed, who offered their Alpha Jet to fulfil the requirement. The VTX-TS competition was not simply for the procurement of an aircraft in isolation; it comprised five core areas: the aircraft itself, capable flight simulators, matured academic training aids, integrated logistic support, and program management. For their proposal, MDC was the prime contractor and systems integrator, BAe functioned as the principal subcontractor and partner for the aircraft element, Rolls-Royce provided the Adour engine to power the aircraft, and Sperry is the principal subcontractor for the simulator system. During November 1981, the U.S. Navy announced that it had selected the Hawk as the winner of the VTX-TS competition. Reportedly, approximately 60 per cent of the work on the T-45 program was undertaken overseas in Britain. During September 1982, a Full Scale Engineering Development contract was awarded to the MDC team to fully develop and produce the proposed aircraft, which had been designated T-45 Goshawk. On 16 April 1988, the first T-45A Goshawk conducted its maiden flight. For more details of the development and design, operational history and variants, click here.
