In October 1916, Commodore Murray Sueter, the Air Department's Superintendent of Aircraft Construction, solicited Sopwith for a single-seat aircraft capable of carrying a 1,000 lb torpedo and sufficient fuel to provide an endurance of four hours. The resulting aircraft, designated T.1 by Sopwith, was a large, three-bay biplane. Because the T.1 was designed to operate from carrier decks, its wings were hinged to fold backwards. The T.1 could take off from a carrier deck in four seconds, but it was not capable of making a carrier landing and no arresting gear was fitted. A split-axle undercarriage allowed the aircraft to carry a 1,000 lb Mk. IX torpedo beneath the fuselage.
