[edit] Design and development
The prototype M.5 Sparrowhawk was developed from standard Miles Hawk components as an entry into the King's Cup Race of 1935 piloted by F.G. Miles. The standard Hawk fuselage was shortened and accommodation was for only one pilot, sitting as low as possible. The top decking was reduced in height, a special high-compression version of the de Havilland Gipsy Six engine was fitted, and the undercarriage track was widened. Although the Sparrowhawk won the 1935 speed prize at an average of 163.64 mph over 953 miles it only came 9th overall in the race. A further five Sparrowhawks (designated M.5A) were also built as King's Cup Racers and three were delivered to customers but they did not perform spectacularly. The final two M.5A Sparrowhawks were built in 1936 but were not flown until 1940. One was modified and flown to meet a requirement for an experimental aircraft for high-lift flap research with the Royal Aircraft Establishment, it was later de-modified and used as a communications aircraft. The sixth Sparrowhawk was modified with short span wings and wide chord flaps for experimental work. The prototype, registered G-ADNL, was modified in 1950 as a jet-powered racer. The front fuselage and tail unit were modified and it was re-designated the M.77 Sparrowjet. The Sparrowjet was powered by two Turbomeca Palas gas turbine engines fitted in the wing roots and eventually achieved its original purpose and won the King's Cup Race in 1957 at an average speed of 228 mph.

One Sparrowjet was impressed into service with the South African Air Force in 1940.
