Founded on 7 January 1917 at Montrose, the squadron trained at RAF Spitalgate and RAF Wyton, where it equipped with Royal Aircraft Factory F.E.2bs and F.E.2ds for its role as a night bomber squadron. The squadron moved to France in March 1918 and attacked German troop concentrations to try and disrupt the German Spring Offensive, before operating for the remainder of the war on night bombing and reconnaissance operations. The squadron was disbanded on 31 December 1919.
The squadron re-formed at RAF Turnhouse in Scotland on 4 August 1936, equipped with Hawker Hinds for day bombing as part of 2 Group. On 14 March 1938, the squadron joined No 5 Group at Scampton and re-equipped with Handley Page Hampdens in October 1938. Unlike many Bomber Command squadrons, No. 83 Squadron went into action on the first day of the Second World War, carrying out a sweep over the North Sea looking for German warships. The squadron continued with 'precision' raids against German naval and coastal targets but as the daylight operations became more costly, Bomber Command switched to night operations. The squadron flew against concentrations of invasion shipping in the Channel Ports in the late summer and autumn of 1940, with a raid on Antwerpon the night of 15 September resulting in the award of a Victoria Cross to Flight Sergeant John Hannah, a wireless operator/gunner for extinguishing a serious fire while receiving severe burns. In December 1941, the squadron was re-equipped with Avro Manchesters but due to their underpowered and unreliable engines these were quickly replaced by Avro Lancasters. In August 1942, the squadron was transferred to the No 8 GroupPathfinder Force at RAF Wyton, operating as a marker unit for the main force of Bomber Command. In April 1944, 83 Squadron was returned to No 5 Group at RAF Coningsby, where it became the Pathfinder unit for independent operations by the Group. , Germany In May 1946, the squadron re-equipped with Avro Lincolns, relocating in October to RAF Hemswell. It deployed to Singapore in September 1953, flying bombing missions against the supposed hiding places of Communist insurgents during the Malayan Emergency, returning to Hemswell in January, where it remained until disbanding again in December 1955.
Post-Second World War and disbandment
In May 1957, the squadron re-formed at RAF Waddington as the RAF's first Avro Vulcan squadron. In August 1960, it handed over its Mk1 aircraft to 44 Squadron and moved to RAF Scampton where it became the first squadron to receive the Vulcan Mk2. Initially these were armed with Yellow Sunnuclear weapons, later to be replaced by Blue Steel stand-off bombs. The squadron remained at Scampton in this role until finally disbanded in August 1969.
