History: Formed at Kirton-in-Lindsey on 5 September 1940 as a night fighter unit equipped with Defiants, becoming operational on 8 December. In January 1941 it began defensive operations over Merseyside before moving south in March. In August 1941 the Squadron converted to Beaufighters which it flew until re-equipping with Mosquitos at the end of 1942. In May 1943 it began flying intruder missions over Europe until its role was changed to bomber support accompanying Bomber Command’s heavy bombers countering night fighter opposition to their raids in January 1945. It remained as part of Fighter Command until its disbandment on 2 January 1947.
