803 Naval Air Squadron

803 Naval Air Squadron (803 NAS), sometimes called 803 Squadron, was a Fleet Air Arm (FAA) naval air squadron of the United Kingdom's Royal Navy (RN). It most recently operated the Blackburn Buccaneer, between July 1967 until December 1969.

Initially part of the Royal Air Force (RAF), the squadron was operational on four occasions from 1933 to 1946, subsequently transitioning to a Royal Canadian Navy (RCN) squadron from 1946 to 1951. It had an additional four separate periods of activity within the Royal Navy from 1951 to 1969. Between 1933 and 1938 the squadron flew Hawker Nimrod and Hawker Osprey within the RAF. It was operating with Blackburn Skua and Blackburn Roc by the time it moved over to the Royal Navy in 1939, before re-equipping with Fairey Fulmar and later Hawker Hurricane and Hawker Sea Hurricane. During its time as part of the RCN it initially flew Supermarine Seafire but these were replaced with Hawker Sea Fury. Reformed as part of the Royal Navy it operated with Supermarine Attacker. These were followed by the Hawker Sea Hawk and later the Supermarine Scimitar.
