fuselage, accommodating a third crew member. The Danes also purchased a licence to build a further ten aircraft at the Danish Naval Workshops (Orlogsvaerftet), but these were not built owing to a shortage of funds. Production aircraft were powered by the Condor IIIA, but the Horsley was also much used as a flying testbed for other engines, including the Napier Lion, Rolls-Royce Buzzard, Rolls-Royce Eagle, the Armstrong Siddeley Leopard radial engine, the Junkers Jumo diesel engine and early versions of the Rolls-Royce Merlin. Operational history The first aircraft were delivered to No 100 (Bomber) Squadron of the Royal Air Force in September 1927, with two more squadrons, No. 15 and No. 11 Squadrons receiving Horsleys by the end of the year, replacing the Fairey Fawn. The Horsleys proved greatly superior to the Fawn, carrying up to three times the bomb load over greater ranges and at higher speeds, while also being agile for their size, and were popular with their pilots. In October 1928, No. 36 Squadron formed at Donibristle, Fife, Scotland as a torpedo-bomber squadron. It was transferred to Singapore in 1930, helping to suppress a rebellion in Burma as well as maintaining its torpedo bombing skills. 100 Squadron converted to the torpedo bombing role in 1930 to fill the gap in home-based defences. The Horsley was chosen to attempt a non-stop flight to India, with a specially modified aircraft, carrying much more fuel and taking off at a weight of over 14,000 lb (6,350 kg) took off from RAF Cranwell on 20 May 1927, flown by Flight Lieutenants Roderick Carr and L.E.M Gillman. It ran out of fuel en route, however, ditching in the Persian Gulf near Bandar Abbas, Iran. Despite this it had covered a distance of , which was sufficient to set a new world distance record, but was beaten in turn within a few hours by Charles Lindbergh, whose solo Atlantic flight between New York and Paris in the Spirit of St. Louis covered ). The Horsleys remained in service in the day-bombing role until 1934, with 504 Squadron's Horsleys being replaced by Westland Wallaces in March 1934. No 36 Squadron at Singapore retained the Horsely in the Torpedo bomber role until July 1935. The last Horsley, a Merlin-powered testbed flew its final flight at RAE Farnborough on 7 March 1938. A total of 124 Horsleys were built, including six aircraft for the Hellenic Naval
