No. 684 Squadron RAF

No. 684 Squadron RAF was a photo-reconnaissance squadron of the Royal Air Force from 1943 to 1946.

History
The squadron was formed on 29 September 1943 at RAF Dum Dum near Calcutta, (then) British India, from the twin-engined elements of No. 681 Squadron RAF. It operated in the photo-reconnaissance role, first with the de Havilland Mosquito and the North American Mitchell, and later also with the Bristol Beaufighter and the Supermarine Spitfire. The squadron performed long-range photo-reconnaissance in support of the Burma Campaign. Near the end of the war, the squadron also performed high-speed courier flights. It was disbanded on 1 September 1946 at RAF Seletar, Singapore, by being renumbered to No. 81 Squadron RAF.
