No. 513 Squadron RAF was a non-operational bomber squadron of the Royal Air Force in 1943.
No. 513 squadron was formed from a flight of No. 218 Squadron on 15 September 1943 at RAF Witchford, Cambridgeshire. It worked up for the Short Stirling bomber, but did not obtain operational status, as its aircraft were more needed at the Stirling conversion units and was disbanded on 21 November 1943.
