In 1939 it was gained full control for the all matters relating to administration, control, policy and organisation of the Fleet Air Arm,[3] it underwent various name changes until it was absorbed as part of the merger of the Admiralty into the new Ministry of Defence in April 1964 as part of the Navy Department where it continued until May 1966 when its remit was changed and when became the Directorate of Naval Warfare.

[4] In June 1920 the Air Department was abolished and a new Air Section was established in July 1920,[5] mainly in response to the fact that there was not a single unified authority responsible for co-coordinating all of the other specialist air agencies that included for example aircraft product, this was particularly the case during the interwar years as the problem was further exacerbated because operational command control of aircraft from warships was the responsibility of the Admiralty and the Royal Air Force was responsible for administration and training under the Air Ministry, this situation would not be rectified until two years before second world war.

[7] The administration of the Fleet Air Arm and all its functions on land still remained in the hands Air Ministry despite on-going Admiralty opposition till July 1937 [8] when both departments of state settled the dispute by returning the Fleet Air Arm to the Admiralty.

At first only carrier-aircraft were involved, by May 1939 full administrative and operational control in regard to naval air warfare was passed to the Admiralty [9] In April 1941 operational control of the land-based Coastal Command finally passed to the Admiralty.

[10] The staff division underwent a number of name changes following Naval Staff re-structuring and new functions were assigned to it, including the Air Warfare and Training Division, (1941–1943), the Naval Air Warfare & Flying Training Division,[11] (1943–1950 ) and the Naval Air Warfare Division, (1951–1962), the Naval Air Division, (1963–1964) Post the merger of the Admiralty into the new Ministry of Defence in April 1964 this division it continued in its own name until May 1966 when its remit was amended and it became the Directorate of Naval Air Warfare.
