No. 531 Squadron RAF

No. 531 Squadron RAF was one of the ten Turbinlite nightfighter squadrons of the Royal Air Force during the Second World War.

History
No. 531 Squadron was formed at RAF West Malling, Kent on 8 September 1942, from No. 1452 (Turbinlite) Flight, as part of No. 11 Group RAF in Fighter Command. Instead of operating only Turbinlite and -rudimentary- Airborne Intercept (AI) radar equipped aircraft (Havocs and Bostons) and working together with a normal nightfighter unit, such as in their case with the Boulton Paul Defiants of No. 264 Squadron RAF or later the Hawker Hurricanes of No. 32 Squadron RAF in the Flight, the unit now also flew with their own Hawker Hurricanes. The squadron moved to RAF Debden, Essex on 2 October 1942, but returned to West Malling a week later. It was disbanded at West Malling on 25 January 1943, when Turbinlite squadrons were, due to lack of success on their part and the rapid development of AI radar, thought to be superfluous.
