Supermarine Sea King

The Supermarine Sea King was a British amphibious biplane fighter designed and built by the Supermarine Aviation Works in 1920.
Design and development.
In 1919, Supermarine commenced design of a single seat flying boat fighter resembling the Baby of the First World War and the contemporary Sea Lion racing aircraft. The resulting aircraft, known as the Sea King, was a single seater biplane powered by a pusher Beardmore 160 hp engine, first flying in early 1920, and later refitted with a Siddeley Puma.
In 1921, Reginald Mitchell, by now chief designer of Supermarine, produced a revised design, possibly to meet the requirements of Specification N6/22 for a fighter capable of operating both from the deck of an aircraft carrier and from water. The resulting Sea King II was a single seat biplane, with a wooden hull, a retractable main landing gear and a fixed tail skid. The tail was of monoplane type mounted halfway up the single fin with a single rudder. The Sea King II was powered by a single Hispano-Suiza 8 engine.
The Sea King II first flew in December 1921. While it demonstrated excellent manoeuvrability, the Sea King was not selected for production. The Fairey Flycatcher and Parnall Plover, both biplanes that could be converted between having conventional tailwheel undercarriage and floats were ordered in small numbers for further evaluation, the Flycatcher finally being successful in equipping the Royal Navy's carriers.
This was not the end for the Sea King, however, as the Sea King II was rebuilt to become the Sea Lion II racer, winner of the 1922 Schneider Trophy.
