The RAF was replacing their Gnat and two-seater Hawker Hunters with the Hawker Siddeley model 1182 that the RAF named the Hawk. The first Hawk T1 was delivered in 1976 just prior to Hawker Siddeley and other companies merging to form British Aerospace in 1977. In a later merger with Marconi Electronic Systems, BA would become BAE Systems. A total of 176 Hawk T1s were produced for the RAF. Hawk T1 XX289 was received in October 1979 and converted to a T1A in 1984 and transferred to 100 Squadron 1995.
