RAF 681 Squadron
Motto: Nulla Rosa Sine Spina (No rose without a thorn)
Role: photo-reconnaissance
Formed from No 3 PRU at Dum Dum in India on 25 January 1943, its main task was photo reconnaissance over Burma and Siam. To carry out this work, it was equipped with Hurricanes, Spitfires and Mitchells. Although some Mosquitoes were received, these were found unsuitable for operation in the highly humid conditions of SEAC and by December 1943 the squadron was solely a Spitfire unit.
The first Spitfire XIX arrived on 28 June 1945 and by VJ-Day had 11 on strength with a further five arriving after that date. In September 1945, No 681 moved to Hong Kong sending detachments to Java and Indo-China. It moved to Seletar in January 1946 with a detachment in Siam but in April the whole squadron moved to India and on 1 August 1946 it was disbanded by being re-numbered No 34 Squadron.
In November 1943 the twin-engined elements were used to form No. 684 Squadron RAF. 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, 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.
