Reformation and World War II

The squadron was re-formed at RAF Calshot on 30 March 1937.  It was at initially equipped with Supermarine Scapas and after a year converted to Short Singapores, which were followed a year later by the Saro London, planning to convert later to Saro Lerwicks, but getting Supermarine Stranraers in June 1940 instead.  During March 1941 these were replaced with Consolidated Catalinas, to carry out anti-submarine patrols over the Atlantic Ocean. It then moved to India in March 1942 where it flew anti-shipping and submarine patrols from Red Hills Lake, where it was disbanded on 1 July 1945.  
The squadron reformed that same day, 1 July 1945, from elements of 212 Squadron and 240 Squadron's Special Duties Flight. The squadron was continuing "special duties" into September 1945, evacuating Operation "Lunch" from the Andaman Islands on 7 September 1945. The squadron converted to Short Sunderland Mk.Vs and moved to Ceylon in 1945, where it disbanded on 31 March 1946 at RAF Koggala.

Post war: Shackletons and Missiles
On 1 May 1952 the squadron re-formed again at RAF Aldergrove and was equipped with Avro Shackleton Mk.1a maritime reconnaissance aircraft.  The squadron moved to Northern Ireland in June 1952, where it disbanded on 1 November 1958 at RAF Ballykelly by being renumbered to 203 sqn.

The squadron reformed once again on 1 August 1959, as one of 20 Thor Strategic Missile (SM) Squadrons, associated with Project Emily. The squadron was equipped with three Thor Intermediate range ballistic missiles, and stationed at RAF Breighton.
