No. 1451 (Fighter) Flight was formed at RAF Hunsdon, Hertfordshire on 22 May 1941, equipped with Turbinlite Douglas Boston and Douglas Havoc aircraft.[2] On operations they co-operated at first with Hawker Hurricanes of No. 1422 Flight RAF and later with Hurricanes of 3 Squadron.[3] The flight was replaced with 530 Squadron on 8 September 1942[3] (not on 2 September due to administrative reasons)[4] but officially disbanded as late as 25 January 1943.[3]
530 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.[6]
