The Fairey Albacore was a British single-engine carrier-borne biplane torpedo bomber built by Fairey Aviation between 1939 and 1943 for the Royal Navy Fleet Air Arm and used during the Second World War. It had a three-man crew and was designed for spotting and reconnaissance as well as level bombing, dive bombing and as a torpedo bomber. The Albacore, popularly known as the "Applecore", was conceived as a replacement for the aging Fairey Swordfish, which had entered service in 1936. However, the Albacore served with the Swordfish and was retired before it, being replaced by the Fairey Barracuda and Grumman Avenger monoplane torpedo bombers.
