The Fairey Swordfish was a torpedo bomber built by the Fairey Aviation Company and used by the Fleet Air Arm of the Royal Navy during World War II. Affectionately known as the Stringbag by its crews, it was outdated by 1939, but achieved some spectacular successes during the war, notably the destruction of the Regia Marina (the Italian Navy) in the Battle of Taranto and the famous crippling of the Bismarck. It was operated primarily as a fleet attack aircraft, however, during its later years it was also used as an anti-submarine and training craft. Designed in the 1930s, the Swordfish remained in frontline service through to the end of the war in Europe in 1945
