RAF Defford
Air to Surface Vessel (ASV) radar enabled the German U-boat menace to be effectively countered in 1943, and thus was critical to the success of the Battle of the Atlantic.By 1944, H2S radar was enabling accurate navigation and target identification to be achieved by Bomber Command crews, taking part in the strategic bombing offensive.[7][8] Most of the technical and domestic sites at Defford have been dismantled, but the central part of the now disused airfield still houses the Satellite Communications facility operated by QinetiQ.A few are contained within the National Trust property of Croome, including part of the station’s medical facilities, which now house the RAF Defford museum.[11] The worst accident in the history of the unit happened on 7 June 1942, when Handley Page Halifax V9977 crashed, with the loss of all eleven crew and scientists on board, including Alan Blumlein.
