An entry was made by Hawker Aircraft, which was a design by Sydney Camm, the Cygnet.

Two aircraft were built (G-EBMB and G-EBJH) and were entered in the competition, held in 1924 at Lympne Aerodrome, by T. O. M. Sopwith and Fred Sigrist.

In 1925, G-EBMB was entered again in the 100 mi (161 km) International Handicap Race, this time flown by George Bulman, who won at a speed of 75.6 mph (121.7 km/h).

In 1926, both aircraft were entered in the competition piloted by Bulman and Flying Officer Ragg, taking first and second place respectively.

Initially the two aircraft were powered, one by an Anzani, and the other by an ABC Scorpion (both opposed twin-cylinder engines).
