Airfield Bombing Decoy Q45a

Hob Uid: 1416051
Location :
Buckinghamshire
Grendon Underwood
Grid Ref : SP6703019620
Summary : A Second World War bombing decoy at Grendon Underwood that was built to deflect enemy bombing from Royal Air Force Bicester. This site was operational from early 1940 and functioned as both a 'K-type' day decoy and a 'Q-type' night decoy. The 'K-type' decoy consisted of a replica airfield equipped with dummy Battle aircraft, while the 'Q-type' decoy displayed a sequence of lights to simulate an active airfield. The 'K-type' decoy ceased operating on 27th June 1941 as it had become an unconvincing decoy, however the 'Q-type' decoy is referenced as still being active in 1942. By the 1970s the site had been given over to agricultural use and no features of the decoy survive.
