Warmwell's three runways remained grass-surfaced for its entire life even though as the war progressed, and the emphasis became on intruding into German-occupied Europe, many intruder units were based here, using the Supermarine Spitfire, Hawker Hurricane and Tempest, and the Westland Whirlwind, the first twin-engined heavy fighter for the RAF.

The 474th Fighter Group arrived on 12 March 1944 from Oxnard Flight Strip California[4] flying Lockheed P-38 "Lightnings".

After the last RAF squadrons to be based there left and Armament Practice Camps stopped using the ranges by October 1945 the station went onto Care and Maintenance the following month before closing down.

During recent clearance work in preparation for new buildings on the North East side of the old airfield a brick block house and a concrete rifle range were revealed.

Further clearances to build an access road across the south-east corner of the flying field has also resulted in the excavation of a group of the aircraft tie-down points.
