RAF Warboys opened as a training airfield in 1941. In August 1942 the newly-formed 156 Squadron moved in with Vickers Wellingtons. There they remained until March 1944. They became part of No.8 Group’s Pathfinder Force and remained in this role for the rest of the European war, flying first Wellingtons and then the four-engined Lancasters. Their role was to mark targets with incendiary bombs and flares. The squadron played a major part in Bomber Command’s offensive. During operations the squadron lost 45 Wellingtons and 117 Lancaster Bombers.
The DF(Directional Finding)Station was used to triangulate the position of planes using radio signals or radar. There was a preimeter blast proof wall surrounding the DF Station roughly 4 feet thick with a walkway inbetween. This site has seen better days but with the nice light that shines through there are some good photos to be taken.
