The 357th Fighter Group, arrived at Leiston from RAF Raydon on 31 January 1944, replacing the P-47-equipped 358th Fighter Group in the 66th Fighter Wing, VIII Fighter Command.
After March 1944 aircraft of the group were identified by red-yellow-red rings on the propeller spinner and a 12" red and yellow band around the forward part of the nose in the checkerboard pattern of the 66th Fighter Wing groups.

The group consisted of the following squadrons:
362d Fighter Squadron (fuselage code G4), dispersals along the 18/36 runway (357th technical site)
363d Fighter Squadron (code B6), dispersals along the 06/24 runway (Buckles Wood)
364th Fighter Squadron (code C5), dispersals along the 13/31 runway (Moat Farm)
The 357th FG served as an escort group, providing penetration, target, and withdrawal support for bombers that attacked strategic objectives on the Continent and began operations in the assault against the German Air Force and aircraft industry during Big Week, 20–25 February 1944.

The group received a Distinguished Unit Citation for two escort missions in which heavy opposition was encountered from enemy fighters: on 6 March 1944 provided target and withdrawal support during the first attack that heavy bombers of Eighth AF made on Berlin.
On 29 June 1944 the group protected bombers that struck targets at Leipzig.
The unit received second DUC for operations on 14 January 1945 when the group, covering 3rd Division B-17's on a raid to synthetic oil plants at Derben broke up an attack by a large force of interceptors and in the ensuing aerial battle destroyed 56.5 German fighters (later credited as 55.5), the largest number of claims by any Eighth Air Force group on a single mission.

In addition to escort the 357th conducted counter-air patrols, made fighter sweeps, and flew strafing and dive-bombing missions in which it attacked airfields, marshalling yards, locomotives, bridges, barges, tugboats, highways, vehicles, fuel dumps, and other targets.
Participated in the invasion of Normandy in June 1944, the breakthrough at Saint-Lô in July, the Battle of the Bulge, December 1944-January 1945; and the airborne assault across the Rhine in March 1945.

The group flew its last mission, an escort operation, on 25 April 1945 and moved to Neubiberg, Germany on 21 July and was assigned to United States Air Forces in Europe for duty with the army of occupation.

357th FG aces Chuck Yeager (the man who broke the sound barrier) and Bud Anderson were stationed in Leiston.

Cpt.
James Browning, an ace assigned to the 363rd FS, was also stationed here until his death over the Fulda Gap in 1945.
