Vickers Type 123

The Vickers Type 123 was a 1920s British single-seat biplane fighter designed and built by Vickers Limited as a private venture. The only Type 123 was later modified into the Type 141 but, not winning any orders, it was scrapped in 1930.

Design and development
The Type 123 was a conventional biplane powered by a 400 hp (298 kW) Hispano-Suiza T52 (Hispano 12 Jb) engine, built at Weybridge Aerodrome in 1926. It was registered as G-EBNQ in February 1926 and first flew on 11 September 1926. In 1927 it had a 480 hp (358 kW) Rolls-Royce F.XI engine fitted and was redesignated Type 141. It competed unsuccessfully in an Air Ministry fighter procurement competition in January 1928. It was then modified as a fleet fighter to meet Specification 21/26 and carried out trials on HMS Furious (47) in June 1929. Without winning any orders the aircraft was scrapped in 1930.
