# List of Fleet Air Arm groups

This is a list of Fleet Air Arm groups of the Royal Navy, that were either formed or planned. There were two types of groups: there were Carrier Air Groups that administered squadrons which operated on aircraft carriers, and there were Training Air Groups which administered squadrons that operated from airbases.

## Carrier air groups

The squadrons and aircraft wings of the Fleet Air Arm, stationed on Fleet and Light Fleet aircraft carriers, were organized into Air Groups in accordance with United States Navy policy following the conclusion of World War II in Europe. This reorganisation aimed to facilitate operations in the Pacific Theater against Japan in 1945. The structure included complete spare groups for Fleet carriers and half spare groups for Light Fleet carriers.
The carrier air groups were organised according to the classification of aircraft carriers and a standardised strength model that considered the squadrons of the Fleet Air Arm and the types of aircraft. By 30 June 1945, nine out of the planned twenty-two groups had been established based on the squadrons that were available. Additionally, one group was created as a reserve in August 1945, while several others were either formed after World War II or reactivated at a subsequent time.
Carrier Air Groups one to six were designated for the three carriers of the Illustrious-class, with each group comprising two squadrons of Vought Corsair and one squadron of Grumman Avenger, with each squadron containing fifteen aircraft. The two ships belonging to the Implacable-class were assigned Carrier Air Groups seven to ten, with each ship featuring two squadrons of twenty-four Supermarine Seafire, one squadron of fifteen Grumman Avenger, and one squadron of fifteen Fairey Firefly. HMS Indomitable, the sole representative of her class, was allocated Carrier Air Groups eleven and twelve, each consisting of two squadrons of twenty-four Grumman Hellcat, one squadron of fifteen Grumman Avenger, and one squadron of twelve Fairey Firefly.
The first four carriers of the Colossus-class were planned to have Carrier Air Groups numbered thirteen to eighteen, with each group including a Vought Corsair squadron of twenty-one aircraft and a squadron of twelve Fairey Barracuda. The subsequent ships in the Colossus-class were assigned Carrier Air Groups nineteen to twenty-two, with number nineteen to be crewed by the Royal Canadian Navy; each of these groups would comprise one squadron of twenty-one Supermarine Seafire and one squadron of twelve Fairey Barracuda.

After operating in the Mediterranean, the group disbanded upon returning to RNAS Lee-on Solent, in July 1948. It reformed the same year as a Royal Australian Navy Air Group for HMAS Sydney. | |
