Sopwith Admiralty Type 860

The Sopwith Admiralty Type 860 was a British biplane seaplane torpedo bomber designed and built for the Admiralty by the Sopwith Aviation Company in 1914. It first flew in December 1914 as an unswept biplane with strut-braced extensions on the upper wings and ailerons on all four wings. It rode on twin strut-mounted floats under the fuselage with a float under the tail and at each wingtip, and its two tandem open cockpits sat above a single 810 lb torpedo slung beneath the fuselage. Some were powered by a nose-mounted 200 hp fourteen-cylinder engine and others by a 225 hp Sunbeam Mohawk. It was built in two versions, with equal-span wings or a shorter lower wing, both with folding wings, and it stayed in service with the Royal Naval Air Service until at least 1916.
