1452 (Fighter) Flight was formed at RAF West Malling on 22 May 1941, equipped with Turbinlite Douglas Boston and Douglas Havoc aircraft.

[2] 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[3] (not on 2 September due to administrative reasons)[4] but officially disbanded as late as 22 January 1943.

[3] 531 Sqn, which had taken over men and machines, carried on flying the Turbinlite Bostons and Havocs till the system was abandoned on 25 January 1943,[5] when Turbinlite squadrons were, due to lack of success on their part and the rapid development of AI radar, thought to be superfluous.
