1454 (Fighter) Flight was formed at RAF Colerne, Wiltshire on 27 June 1941, equipped with Turbinlite Douglas Boston and Douglas Havoc aircraft.

[2] By 26 January 1942 the flight moved to RAF Charmy Down, Somerset.

[3] On operations they co-operated with the Hawker Hurricanes of 87 Squadron,[4] which also flew from Charmy Down.

The flight was replaced with 533 Squadron[3] on 8 September 1942 (not on 2 September due to administrative reasons)[5] but officially disbanded as late as 31 January 1943.

[3] 533 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,[6] when Turbinlite squadrons were, due to lack of success on their part and the rapid development of AI radar, thought to be superfluous.
