F.20/27

hawkf20-27


This experimental single-seat interceptor fighter designed by Sydney Camm to meet the requirements of Specification F.20/27, was flown in August 1928 with a 450hp Bristol Jupiter VII radial. Of metal construction with sharply staggered single-bay wings and a twin-Vickers gun armament, the prototype was re-engined with a 520hp Mercury VI in May 1930. It demonstrated a maximum level speed of 325km/h. By this time the F.20/27 specification had prompted Hawker to initiate development of a more advanced fighter as a private venture, and this, owing much to the F20/27, was to emerge as the Hornet in 1929.
