This is a List of Fleet Air Arm aircraft squadrons, squadrons in Bold Type are currently active in the Royal Navy Fleet Air Arm. Squadrons in underline subsequently commissioned into Royal Australian Navy Fleet Air Arm. Squadrons in italics subsequently commissioned into Netherlands Naval Aviation Service.

With the formation of the Fleet Air Arm in 1924, as a part of the Royal Air Force, blocks of squadron numbers were used. Nos. 401-439 were Fleet Fighter / Spotter Flights, assigned to Royal Navy battleships and cruisers.^[1] Nos. 440-459 were Fleet Reconnaissance Flights, many later becoming Fleet Spotter Reconnaissance Flights, and No. 460 onwards, as Fleet Torpedo Flights, later becoming Torpedo Bomber Flights.^[2]

In 1936 some of these were renumbered in the 700 series and this was retained when the Admiralty regained full control of the Fleet Air Arm in 1939. Nos. 700-749 were for catapult flights and squadrons, but eventually these all merged into 700 Naval Air Squadron, leaving nos. 701-710 for amphibian and floatplane squadrons from 1943 onwards. Nos. 750-799, were assigned for training and ancillary squadrons (in contrast to the RAF practice of not assigning squadron numbers to training units).^[1]

Front line combat squadrons were nos. 800-899 and broken down into categories:^[2] nos. 800-809 for fighter squadrons, nos. 810-819 for torpedo bomber squadrons, later torpedo spotter reconnaissance (TSR), and torpedo bomber reconnaissance (TBR), squadrons, nos. 820-859 were initially spotter reconnaissance squadrons, later becoming TSR and, finally, TBR squadrons. Originally, TBR squadrons included 860-869, but these were assigned to Dutch-manned and then Royal Netherlands Navy squadrons. Nos. 870-899 were initially for single-seat fighter squadrons, but 870-879 were later assigned to Royal Canadian Navy squadrons. As these numbers ran out, new series prefixed by '1' were allocated. Leaving aside unused blocks, nos. 1700-1749 became torpedo bomber reconnaissance squadrons and two-seat fighter squadrons were nos. 1770-1799. Dive bomber squadrons were nos. 1810-1829 and nos. 1830-1899 were for single-seat fighter squadrons.^[3]
