RAF Annan

Royal Air Force Annan, or more simply RAF Annan, is a former Royal Air Force station located about 2 mi north-east of the town of Annan, Dumfries and Galloway, Scotland, which was operational during the Second World War.

Station history
Initially serving as a sub-site of No. 18 Maintenance Unit in 1940–1941, RAF Annan was opened as an air station in April 1942 as the base for No. 55 Operational Training Unit RAF (OTU), to train fighter pilots. As part of No. 81 Group 55 OTU pilots flew at low level over the Solway Firth training to fly "Rhubarb" missions, crossing the English Channel to attack targets of opportunity in France and the Low Countries. Initially they flew Hawker Hurricanes; and later, Miles Master trainers and Hawker Typhoon fighter-bombers. In June 1943 55 OTU was transferred to No. 9 Group; and on 26 January 1944 was redesignated No. 4 Tactical Exercise Unit (TEU), then No. 3 TEU on 28 March 1944. No. 3 TEU moved to RAF Aston Down in July 1944, and Annan then served as a sub-site of No. 14 Maintenance Unit from August 1944 until August 1952.

The main technical area was in the north-eastern sector, and there were at least seven blister hangars around the perimeter. There was a camp about 600 m north-east of the airfield near the village of Creca which contained various accommodation buildings, huts, and air raid shelters. Another camp existed about 500 m south of the airfield.
