In November 1943 the twin-engined elements were used to form No. 684 Squadron RAF.[7] 681 Squadron, which was now entirely equipped with the Spitfire PR.XI, moved to RAF Alipore, Bengal in May 1944, where the squadron was under No. 171 Wing RAF on 1 July 1944 [1], and RAF Mingaladon, Burma in June 1945, receiving Spitfire PR.XIX photo-reconnaissance aircraft in August of that year. The squadron moved to RAF Kai Tak, Hong Kong, in September 1945, when the war formally ended. Detachments from the squadron however were still located and kept busy at a wide range of airfields across the South-East Asian theatre of war. The squadron was disbanded by renumbering it to No. 34 Squadron RAF on 1 August 1946 at RAF Palam, Punjab, (then) British India.[4][8][9]
