The station had never been officially transferred from the RAF and the anti-aircraft support units were quick to return. Several Squadrons were based at Westonzoyland, but the longest stay was by No. 16 Squadron RAF with Westland Lysanders, and later with the North American Mustang. Later Supermarine Spitfires became a common sight being flown by No. 19 Squadron RAF and others. Nos. 286 and 587 Squadrons with their mixture of Miles Martinets, Hawker Hurricanes, Airspeed Oxfords, Vultee A-31 Vengeances and North American Harvards remained in residence until near the end of hostilities. 587 Squadron was formed at RAF Westonzoyland, on 1 December 1943, from 1600 Flight, 1601 Flight and 1625 Flight for anti-aircraft co-operation duties over Wales and the south east of England. It operated a variety of aircraft in this role. Due to the ongoing training requirement the squadron was not disbanded at the end of the war and it moved to RAF Tangmere on 1 June 1946 to cover the south coast, but was disbanded shortly afterwards on 15 June 1946.
