The Hawker Horsley first flew in March 1925. Designed by Roy Fedden and the team at Hawker Aircraft, this large single-engine, two-bay biplane hold the distinction of being the last all-wooden Hawker model. Maiden Flight was in March 1925, by Flt Lt P.W.S. Bulman. It was powered by a single Rolls-Royce Condor III engine. Tested in May 1925, it showed it could lift up to 1,390 lbs. From the Mk.II they were composite made, later all-metal (Mark III), used as medium day torpedo bomber. However it never entered the Fleet Air Arm nor was designed for carrier service. Instead all these torpedo bombers operated from RAF bases along the coast, long before the coastal command was created. The Horsley entered service in 1926, and was notably deployed from Singapore until 1935. Greece and Denmark (with the Dantorp floatplane) operated them still in 1940.
