1935 to 1945 - SUPERMARINE WALRUS - Reconnaisance Amphibian - 740 Walrus aircraft were built, initially to operate as reconnaisance aircraft from cruisers and later in the air/sea rescue role. Despite it's rather antique appearance, the Walrus could claim a number of firsts: firsr British squadron service aircraft with a fully retractable undercarriage, first with an all-metal fuselage and first with a fully enclosed cockpit. By the middle of World War 2, radar had replaced it in the reconnaisance role and it was used in the air/sea rescue role by both the FAA and RAF. It was flown in total by 10 Air Arms, service with the Argentine Navy until 1958. This picture shows one of the original aircraft, designated Seagull V, in the RAF Museum at Hendon.
