783 Naval Air Squadron (783 NAS) was a Naval Air Squadron of the Royal Navy's Fleet Air Arm which last disbanded in November 1949. 783 Naval Air Squadron was formed as an ASV Training Squadron (air-to-surface-vessel radar) at HMS Condor, RNAS Arbroath, Scotland, in January 1941. It operated a number of ‘flying classroom’ aircraft alongside other types. It operated in conjunction with the Naval Air Signals School (NASS) from March 1943. The squadron moved to HMS Daedalus, RNAS Lee-on-Solent, England, when the NASS moved south, also supporting the Flag Officer, Air, Home Communications Officer and from July 1948,it was part of the 51st Miscellaneous Air Group.
783 Naval Air Squadron formed on 9 January 1941 at RNAS Arbroath (HMS Condor) as the air-to-surface-vessel (ASV) radar training squadron. Essentially the squadron formed from an existing ASV training Flight which was based at HMS Condor. It was quipped with Fairey Swordfish, a biplane torpedo bomber, Fairey Albacore, also a biplane torpedo bomber, and Supermarine Walrus, an amphibious maritime patrol aircraft. It also used a de Havilland DH.86 Express which was fitted out as an air-to-surface-vessel radar flying classroom, although the main flying classroom operated was the Avro Anson, a multirole aircraft, used primarily as a trainer aircraft. The de Havilland Express was damaged by ‘friendly fire' from a Royal Navy minesweeper and was replaced with a Vickers Wellington, a long range medium bomber and over time more of these aircraft were received, equipped with ASV radar.
From March 1943, 783 Naval Air Squadron operated in conjunction with the Naval Air Signal School, at RNAS Arbroath. It received Fairey Firefly, a carrier-borne fighter and anti-submarine aircraft, Fairey Barracuda, a carrier-borne torpedo and dive bomber, and Grumman Avenger, an American torpedo bomber. In May 1947 the squadron moved south relocating to RNAS Lee-on-Solent (HMS Daedalus), in Hampshire, with the Naval Air Signal School now based at Seafield Park, Hampshire which was situated next to the airbase. At then at the end of the year it temporarily operated a number of Fairey Barracuda TR.5, before receiving new Avro Anson aircraft. The squadron also operated an Avro Anson for use by the Flag Officer, Air, Home Communications Officer. The following year, in July 1948, the squadron made up part of the 51st Miscellancous Air Group and then in 1949 it ran a radio refresher course for Observers and Aircrew. 783 Naval Air Squadron disbanded on 18 November 1949.
