In the 1980s lists of United States Army Air Force Station Numbers appeared in various issues of Airfield Review, the journal of the Airfield Research Group.  Unfortunately these were incomplete and followed no logical order.  I put together this article to right this and it was published in Airfield Review No. 68 in April 1995.  It should hopefully explain how the numbering systems worked. Based on information available. it is believed that the later (September 1942 onwards) lists are comprehensive. Due to limitations of space no attempt has been made to describe the use or users of the individual stations. For example, a bomber airfield would have had in addition to its main group, numerous other separate units and detachments also on site such as Air Service Command technicians, Military Police, etc. and it would be impractical to include all this additional information. The original system of identifying USAAC/USAAF stations and bases in the European Theatre of Operations (ETO) during World War Two used a letter and number combination. The prefix letters were:

     B = Bomber Airfields

     D = Rear Supply Depots

     O = Observation (Reconnaissance) Airfields

     P = Pursuit (Fighter) Airfields

     R = Repair and Rectification Depots

Station numbers

for 4 June 1942

of bases allocated

to the USAAF.

Fighter Bases

P- 1











P- 7









High Ercall

Eglinton, Maydown, St.Angelo and Kirkiston were other airfields in the 4 June 1942 allocations. It is possible that P-4 could be identified as Hibaldstow.

Bomber Bases




Grafton Underwood 









B- 7



Little Staughton 






East Wretham
















Horsham St. Faith 








Earls Colne




Thorpe Abbotts




Market Harborough



Repair Depots






Langford Lodge

Rear Supply Depots











Observation Bases






Other bases were identified on I September 1942, as were further prefix letters.                                                                                   

Q = Quartermaster Depots.

T = Transport

Also OA and M which apparently stood for Observation and Maintenance respectively. OA in particular is odd as O was already the designated letter for Observation bases.

Fighter Bases

P-14 Bushey Hall (HQ)                    P-15 Westhampnett

Quartermaster Depots.

Q-101 Kettering                              Q-I02 Wellingborough

Bomber Bases

B-32 Alconbury                               B-33 Brampton Grange (HQ)

Repair Depot

R- 7 Melchbourne Park


T -I Ramsbury               T -2 Aldermaston               T-3 Greenham Common

Maintenance (?)

M-I Rushden                M-4 Thrapston

Observation (?)

OA-2 Membury

As the American build up continued many more airfields and bases would be required by the Army Air Forces and later on in September 1942 the familiar numerical system was introduced. The numerical blocks were to be allocated to Commands thus:

From 101 = Vlllth AF Bomber Command

From 231 = Vlllth AF Composite Command

From 341 = Vlllth AF Fighter Command

From 466 = Vlllth AF Ground Air Support Command                                                                                                     

From 571 onwards = Vlllth AF Service Command

Once a number had been allocated, whether to an airfield or non-flying establishment, it was rarely changed, therefore any change of unit or use on a particular site (such as a bombardment group replacing fighter group), meant that the system was soon in disarray with special regard to airfields. This was further complicated in the autumn of 1943 when the Ninth AAF was reconstituted in the UK and elements of the Eighth AAF, such as the four medium bomb groups, were transferred to this tactical air ann. The Ninth's maintenance and supply also meant that homes had to be found for the IX Service Command.

At first glance the method used in the allocation of the numbers may seem to rather haphazard. Many do not seem to follow in any logical order of either planning, construction, opening dates or dates of occupancy. Some planned airfields were never constructed but were nevertheless given a number (some reallocated later; see the 170 series range), while others never actually occupied by the USAAF still retained their numbers. And finally, some sites known to have been occupied by the US do not seem to have been numbered

An attempt was made to keep within the set parameters of the system and for the VIII GASC and VIII AFSC these worked both ways from the start points. Initially the earlier sites were renumbered. In the years that followed numbers were allocated from anywhere they were available within the particular ranges. Frequently batches of airfield names would be received from the British and these often show up as blocks in alphabetical order, e.g., 148 to 159 or 355 to 361. Note also the block 410 to 419 which are all ALGs. However, from 379 many of the numbers went to any type of station. In most instances depots on or adjacent to airfields were given different names and numbers. It is also interesting that a depot would take its name from a village on the opposite side of the airfield. For example, Hitcham - Wattisham.  The Hitcham depot was in Nedging.

The following numerical listing gives all known allocations of AAF Station numbers given to both flying and non-flying sites in the United Kingdom. Numbers marked with an X denote an airfield or other flying establishment and those marked * after the number denote an airfield that was not constructed. Only the "official" name is given for the sake of brevity. Counties are given as they were in World War Two.

Listed separately are non-UK sites allocated numbers. UK sites known to have had USAAF occupancy or were allocated but never taken up and to which no number is recorded have not been included in this article. Most of these were Military Police stations frequently located in private houses.

(b) Winfarthing 140 became Fersfield 554

(c) Butley 151 became Bentwaters

(d) Records do not specify which of the airfields in Iceland used by the USAAF is 354. The US constructed Meeks and Patterson Fields at Reykjavik and also Kassos Field on the north side of the island. The main tactical airfield of Reykjavik was under the jurisdiction of the RAF and only used occasionally by the USAAF.
