}}No. 684 Squadron RAF was a photo-reconnaissance squadron of the Royal Air Force from 1943 to 1946. HistoryThe squadron was formed on 29 September 1943 at RAF Dum Dum near Calcutta, (then) British India from the twin-engined[3] elements of No. 681 Squadron RAF.[2] It operated in the photo-reconnaissance role with first 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.[2][6][7] Aircraft operatedAircraft operated by no. 684 Squadron RAF, data from[3][6][8]| From | To | Aircraft | Variant | | September 1943 | September 1945 | North American Mitchell | Mk.II (B-25C) | | September 1943 | December 1943 | de Havilland Mosquito | Mk.II | | September 1943 | February 1944 | de Havilland Mosquito | Mk.VI | | October 1943 | February 1945 | de Havilland Mosquito | Mk.IX | | February 1944 | May 1946 | de Havilland Mosquito | Mk.XVI | | May 1945 | July 1945 | Bristol Beaufighter | Mk.VI | | July 1945 | September 1946 | de Havilland Mosquito | PR.34 | | July 1945 | July 1946 | Bristol Beaufighter | Mk.X | | December 1945 | September 1946 | Supermarine Spitfire | PR.XI, PR.XIX | Squadron bases Air bases and airfields used by no. 684 Squadron RAF, data from[3][6][8]| From | To | Name | Remark | | 29 September 1943 | 9 December 1943 | RAF Dum Dum, Bengal, British India | Formed here | | 9 December 1943 | 31 January 1944 | RAF Comilla, Bengal, British India | | 31 January 1944 | 5 May 1944 | RAF Dum Dum, West Bengal, British India | | 5 May 1944 | 11 October 1945 | RAF Alipore, Bengal, British India | Detachments at RAF Yelahanka, Karnataka, British India;
