It was reformed on 20 July 1936 from 'C' Flight, No. 19 Squadron RAF at RAF Duxford, initially being equipped with Gloster Gauntlets, before a slow conversion to Supermarine Spitfires from August 1938. The squadron was part of No. 12 Group RAF in Fighter Command and was on readiness from the start of the war in September 1939. The first contact with the enemy was an attack on a Heinkel He 111 of the Norfolk coast near Cromer, the German aircraft subsequently crashed in Denmark. The squadron moved to RAF Horsham St. Faith after the Germany invasion of Belgium and the Netherlands, the squadron destroyed its first enemy aircraft on 12 May 1940 over the Hague. At the end of August the squadron moved to the south of England as part of the Battle of Britain, it operated from RAF Kenley, RAF Gravesend, RAF West Malling and by November to RAF Biggin Hill. By the time the Germans had stopped daylight bombing the squadron had destroyed 20 aircraft with another 17 probables and also damaged another fifteen.
In April 1941 the squadron moved to Perranport in Cornwall to operate fighter sweep missions over the Channel, it moved to Portreath in December 1941 and re-equipped with the Spitfire V. In April 1942 the squadron moved to RAF Ibsley and was involved in the support for the combined operations at Dieppe. It moved to the Orkney island to provide fighter cover for the British fleet based at Scapa Flow before returning to Cornwall in October 1943.
In November 1943 the squadron moved to RAF Hornchurch and converted to the Spitfire IX. The squadron became part of the Second Tactical Air Force and provided air cover for the invasion forces in Normandy, being based in France from 22 June. After a break in South Wales the squadron continued to support the advancing allied forces being based at Abbeville in September 1944 and then on to Grimbergen in Belgium.
