The Sopwith Admiralty Type C was an early Britishfloatplane designed and built by Sopwith Aviation to drop torpedoes. A single engined tractorbiplane floatplane, three were delivered to the Royal Navy in November 1914 but proved unable to lift a torpedo.[1]
Design and development
The Admiralty had ordered a special torpedo carrying biplane (the Sopwith Special torpedo seaplane Type C, serial number170) in February 1914 and followed it with an order in July 1914 for three similar Type C floatplanes (serial numbers 157, 158 and 159).[1] The specification called for folding wings, bomb gear, a gun and radio.[2] Work started at the Sopwith factory at Kingston-upon-Thames on 5 April 1914 and the three Type Cs, powered by a 200 hp (150 kW) Salmson (Canton-Uneé) piston engine, were completed by October.[2] They went to RNAS Calshot for evaluation in November 1914.[1] The Special, tested that July, had failed to lift a torpedo and the new Type Cs were little better, failing to take off under load:[2] 157 could not get airborne with a 14 in (360 mm) Whitehead torpedo and the other two had similar poor performance.[1] 158 was accepted by the service on 4 February 1915 but it sank following a forced landing a few days later on 8 February.[1] The two survivors, 157 and 159, were withdrawn from service at the end of 1915.[1]
