The airfield was located only 3.5 kilometers from the Normandy Gold landing beach, and when it opened the frontline was not much further away.

The group built a 3,600 foot runway and dispersal areas using SMT, while communications facilities were provided by equipment installed in vehicles.

It was used by RAF 144 and 146 Wing and was also used to evacuate injured soldiers, sailors and airmen to England.

In addition a constant stream of other Allied squadrons used the airfield for fuel, ammunition or repair.

On 23 July 1944 Prime Minister Winston Churchill paid a morale boosting visit to B.3 St. Croix-sur-Mer, flown by Air Vice Marshal Harry Broadhurst in his captured Fieseler Storch.
