RAF Steeple Morden

USAAF use

When the airfield was turned over for American use, Steeple Morden was assigned USAAF designation Station 122. Hard-surface runways were laid down, along with concrete hardstands and a permanent T-2 hangar

3rd Photographic Reconnaissance Group
Although not planned for use until 1943 Steeple Morden was first used by the United States Army Air Forces Eighth Air Force 3d Photographic Reconnaissance Group, arriving from RAF Membury on 16 October 1942.
The 3d consisted of the 5th, 12th, 13th, 14th, 15th and 23d squadrons and only stayed at the airfield until 10 December, departing for La Senia Algeria as part of Operation Torch.

During the stay of the 3d PRG, Lieutenant-Colonel Elliott Roosevelt, son of Franklin D. Roosevelt served as commander and also flew an F-4 Lightning.

Between January 1943 and May 1943 the airfield was used by No. 17 OTU which used Bristol Blenheims.

355th Fighter Group
 With the departure of the photo-recon squadrons, the 355th Fighter Group, arrived from Philadelphia Municipal Airport on 9 July 1943. The group was under the command of the 65th Fighter Wing of the VIII Fighter Command. Aircraft of the group were identified by white around their cowling and tail. The group consisted of the following squadrons:
 354th Fighter Squadron (WR)
 357th Fighter Squadron (OS)
 358th Fighter Squadron (YF)

The 355th FG flew its first combat mission, a fighter sweep over Belgium, on 14 September 1943 and afterwards served primarily as escort for Boeing B-17 Flying Fortress Consolidated B-24 Liberator bombers that attacked industrial areas of Berlin, marshalling yards at Karlsruhe, an airfield at Neuberg, oil refineries at Misburg, synthetic oil plants at Gelsenkirchen, locks at Minden, and other objectives. The group also flew fighter sweeps, area patrols, and bombing missions, striking such targets as air parks, locomotives, bridges, radio stations, and armoured cars.

On 5 April 1944, shortly after converting from Republic P-47 Thunderbolts to North American P-51 Mustangs, the group successfully bombed and strafed German airfields during a snow squall, a mission for which the group was awarded a Distinguished Unit Citation.

The group provided fighter cover for Allied forces landing in Normandy on 6 June 1944, and afterwards hit transportation facilities to cut enemy supply lines. Hit fuel dumps, locomotives, and other targets in support of ground forces during the breakthrough at Saint-Lô in July. The 355th Fighter Group flew its last combat mission on 25 April 1945. On 3 July the group transferred to Gablingen, Germany for duty with United States Air Forces in Europe as part of the army of occupation. Transferred, without personnel and equipment, to Mitchel Field New York on 1 August 1946, and was inactivated on 20 November.
