It was to have initially formed in 1939 at HMS Daedalus, RNAS Lee-on-Solent, as a Seaplane School, however, it formed at HMS Landrail, RNAS Machrihannish, as a Night ALT Course, in 1942. It moved to HMS Nightjar, RNAS Inskip, in 1943, to become part of No. 1 Naval Operational Training Unit. By 1944, it was operating over 30 Swordfish aircraft, but, during the year, also acquired Firefly aircraft from 1772 NAS, and Sea Hurricane aircraft from 760 NAS. It moved to HMS Merganser, RNAS Rattray, early in 1946, but later that year, moved to HMS Fulmar, RNAS Lossiemouth, where it received Seafire aircraft, along with being Part 1 of the Operational Flying School. By late 1951, Sea Fury trainer aircraft were also added to its varied list of types operated. In 1953, the squadron moved to HMS Seahawk, RNAS Culdrose, where it disbanded in 1954.
