Operational history

Five production aircraft were built at Shoreham, differing chiefly in the choice of engine. Three of them had 80 hp Armstrong Siddeley Genet II and one a 100 hp Armstrong Siddeley Genet Major. These were five-cylinder uncowled radials. One aircraft had, at different times, a de Havilland Gipsy I or II (100 hp and 120 hp respectively), upright in-line air-cooled engines. The Martlets were not very successful as racers but served a succession of private owners as aerobatic mounts. Martlet ground

Only one Martlet, the Genet Major engined ''G-AAYX'' survived the war. This aircraft was owned for a number of years by F G Miles who used it as a personal mount while based at Woodley near Reading. The aircraft is now part of The Shuttleworth Collection based at Old Warden Aerodrome and underwent an extensive restoration, with return to flight in September 2000. The aircraft is now on permanent display as part of The Collection and is flown at home air displays during the summer months.The Shuttleworth Collection - Southern Martlet
