Supermarine traces its ancestry to the Pemberton-Billing seaplane company of 1913. It was acquired in 1928 by Vickers-Armstrong, but retained an independent identity until it was absorbed in the merger that formed British Aircraft Corp. in 1960. Supermarine was known almost exclusively for flying-boat designs and racing seaplanes until the 1930s, when it designed the Spitfire fighter. Supermarine continued to produce fighters, most notably the Attacker and Scimitar for the Royal Navy and the Swift for the Royal Air Force, until it disappeared into BAC.
Supermarine’s birthplace, headquarters and seaplane producing operations were in Woolston, Southampton. Its most important facility for the production of land-based fighters was at Castle Bromwich.
