The T-45 Goshawk is a highly modified version of the BAE 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 is a fully carrier-capable version of the Hawk Mk.60. It was developed for the United States Navy (USN) for use in training. The Goshawk's origins began in the mid-1970s, when the US Navy began looking for replacement for its T-2 and TA-4 trainers. The US Navy started the VTXTS advanced trainer program in 1978. British Aerospace and McDonnell Douglas proposed a version of the Hawk and were awarded the T-45 contract in 1981.
