Design and development

First flown in December 1914 the Type 860 was an unswept biplane. The upper wings had a strut braced extension and ailerons were fitted on all four wings. It had twin strut-mounted floats under the fuselage and a float mounted under the tail and each wingtip. Some models were powered by a nose-mounted 200 hp 14-cylinder engine; others used a 225 hp (168 kW) Sunbeam Mohawk engine. Both models utilised a two-bladed propeller. It had two tandem open cockpits and could carry one 810 lb (367 kg) torpedo under the fuselage. The Sopwith Admiralty Seaplane Type 860 was built in two versions. The standard version had wings of equal span; the second version had a lower wing of shorter span. In both versions, the wings were designed to fold. The type remained in service with RNAS until at least 1916.[1]
