Sopwith B.1

The Sopwith B.1 was an experimental British bomber aircraft of the First World War. A single-seat, single-engined biplane, the B.1 was built by the Sopwith Aviation Company for the Royal Navy. Although only two were built, one was used for bombing raids over France.

Development and design

In late 1916, Sopwith, whose earlier 1½ Strutter had proved successful as a light bomber, (particularly when operated as a single seater), designed a new, single-engined bomber aircraft. The new bomber was developed in parallel with the Cuckoo carrier based torpedo bomber and closely resembled the Cuckoo. It, like the Cuckoo, was a compact tractor biplane, powered by a 200 hp (149 kW) Hispano-Suiza water-cooled engine. Unlike the Cuckoo, the bomber's two-bay wings did not fold. It was designed as a single-seat aircraft, with the pilot sitting in a cockpit under the wing centre section to give a good view forwards and downwards for bombing. The aircraft bombload of up to 560 lb (255 kg) was carried vertically within the fuselage, in cells behind the pilot.
