Origin
Sir Frederick Pile, GOCinC, AA Command, during World War II

The formation of a Command-level body of anti-aircraft defences had been announced in 1938, but Anti-Aircraft Command was not formed until 1 April 1939 under General Sir Alan Brooke, who had been commander of Anti-Aircraft Corps. He then passed control to Sir Frederick Pile, who would remain in command until the end of the war.[1][2][3]

AA Command was under the operational direction of RAF Fighter Command as part of Air Defence of Great Britain, and occupied a headquarters known as Glenthorn in the grounds of Bentley Priory, home of Fighter Command.[1][4]

The majority of AA Command's guns and searchlights were operated by Territorial Army units. Some Regular Army units joined after they returned from the Dunkirk evacuation. Later, as the war progressed, Regulars and TA were freed up for overseas service by the use of men of the Home Guard (loading and firing the guns) and women of the Auxiliary Territorial Service (handling ammunition and operating gun directors).[1][5]

Organisation

Divisions under the command were:[2][5][6][7][8]

AA Command was also responsible for the Orkney and Shetland Defences (OSDEF).

Corps

At the end of 1940, the Command created three Corps to supervise this expanding organisation:[2][5][7][9]

Groups

In October 1942, the corps and divisions were abolished and replaced by seven flexible AA Groups more closely aligned with the operational structure of Fighter Command:[2][5][13]

(1st and 2nd AA Groups coincided with No. 11 Group RAF)

  • 3rd Anti-Aircraft Group covering South-West England and South Wales (coinciding with No. 10 Group RAF)
  • 4th Anti-Aircraft Group covering North Wales and North-West England (coinciding with No. 9 Group RAF)
  • 5th Anti-Aircraft Group covering northern East Anglia and the East Coast as far as Scarborough, North Yorkshire (coinciding with No. 12 Group RAF)
  • 6th Anti-Aircraft Group covering North-East England and Scotland (coinciding with No. 13 Group RAF (except Northern Ireland) and No. 14 Group RAF)
  • 7th Anti-Aircraft Group covering Northern Ireland
  • OSDEF remained separate

Later events

Later, the 6th AA Group took over the Solent area to cover the preparations for Operation Overlord and was replaced in NE England by a new 8th Anti-Aircraft Group.[2][14]

A new 9th Anti-Aircraft Group was formed to cover southern East Anglia during the flying bomb offensive (Operation Diver).[2][15]

On 1 April 1943, AA Command took over control of smoke screens from the Ministry of Home Security. These installations were manned by the Pioneer Corps.

Postwar

When the TA was reformed after World War II in 1947, AA Command was generously provided for, with a large number of units, some of them including members of the Women's Royal Army Corps (successors of the ATS). It was structured in five regional AA Groups, each commanding a number of TA and Regular AA Brigades:[16][17][18]

On 1 December 1954, it was announced that AA Command would be disbanded with effect from 10 March 1955.[19][20]
