No. 1452 (Fighter) Flight was formed at RAF West Malling on 22 May 1941, equipped with Turbinlite Douglas Boston and Douglas Havoc aircraft. On operations they co-operated at first with the Boulton Paul Defiants of 264 Squadron and later with the Hawker Hurricanes of 32 Squadron. The flight was replaced with 531 Squadron on 8 September 1942 (not on 2 September due to administrative reasons) but officially disbanded as late as 22 January 1943.
