No. 117 Squadron RAF was a Royal Air Force Squadron formed to be a bomber unit in World War I and reformed as a transport and communications unit in World War II.
No. 117 Squadron was formed as a bomber squadron in the Royal Flying Corps on 31 January 1918 and was based at Wyton where it was equipped with the Airco DH.9. The squadron became part of the Royal Air Force and was stationed in Ireland for a time before it was merged with No. 141 Squadron on 6 October 1919.
No. 117 Squadron was reformed on 30 April 1941 at Khartoum, Sudan and incorporated the Khartoum Communications Flight which already had a captured Italian Caproni Ca.148 aircraft that had been impressed into service in 1940.[2] Needing a long range aircraft, four Bristol Bombays were borrowed from No. 216 Squadron and in May a flight of ex-Yugoslav Savoia-Marchetti S.79Ks were taken on charge.[2] When the squadron moved to Egypt in November 1941 to provide transport services, the communications aircraft were left in Khartoum and the Bombays were returned. The whole squadron was reequipped with the Lockheed Hudson. In July–August 1943 it was involved in Operation Husky as part of No. 216 Group and switched to Douglas Dakotas DC-3s based at Castel Benito, Libya. In October the squadron moved to India and in 1944 it transported supplies for the Chindits who operated behind the Japanese lines. The squadron was disbanded on 17 December 1945 shortly after the war with Japan ended.
