The Sopwith 8F.1 Snail was designed by Herbert Smith of Sopwith Aviation Company to meet the Air Board Specification A.1A for a light fighter with superior performance to the Sopwith Camel. Herbert Smith designed a small single-bay biplane, powered by the 170 hp (127 kW) ABC Wasp radial engine. An initial order was placed on 31 October 1917 for six prototypes with a conventional wood and fabric framework structure, but this was revised
Sopwith Hippo for the gunner's Lewis guns was replaced by a more conventional Scarff ring mounting a single Lewis gun. The rebuilt prototype flew in April 1918, with a second prototype following in June. No further production followed. Some sources suggest that, rather than a rebuilt first prototype, that the Hippo with reduced stagger was a new aircraft. Sopwith Hippo The Sopwith 3F.2 Hippo was a prototype British two-seat fighter aircraft of the First World War. It was a single-engined biplane with considerable negative stagger. It was not successful, the Bristol F.2 Fighter (already in production) being preferred by the Royal Flying
