Planned as an RAF bomber OTU and then for other purposes, Mullaghmore was built during 1941-42 with only two runways, but with 30 pan type hardstandings and four T2 hangars. 25 more 'Y’ type hardstandings were added in late 1943. The station was handed over to the Eighth Air Force Composite Command in December 1943, as the home of the 6th Replacement and Training Squadron (Bombardment), plus the HQ and HQ Squadron of the 6th Combat Crew Replacement Centre. They moved to RAF Cheddington in February 1944, after which the station was used primarily as an aircraft store until handed back to the RAF in May 1944. It went under Care & Maintenance in May 1945 and the site then quickly returned to private ownership. Although largely returned to agriculture, part of the airfield remains in use for microlight flying and another part is a stock car racing circuit. A few wartime buildings survive, mostly in derelict condition, but the Control Tower has been preserved and converted as a private home.
