The Squadron was to see extensive action during Second World War. In its first tour of duty between March and September 1944, No. 7 flew a six aircraft detachment against Japanese targets during the Battle of Imphal, initially against Kenji on Chindwin, and later against Japanese supply lines and army convoys along the Tiddim road. In December 1944, No. 7 Sqn moved to Peshawar and converted to the Hurricane Mk.IIc. By March 1945, the unit was back in the Burma Front, flying from Imphal, and later, from Magwe Airfield. It would later move to Samungli in June 1945. In November 1945, the Squadron moved to Gwalior, where it converted to Spitfire Mk.XIVs, which it flew from December 1945 till July 1947, when the squadron converted to the Tempest Mk.II.
