Sufficient P-63 aircraft continued in use by the Soviet's after the war for them to be given the NATO reporting name of "Fred". At the end of World War Two when the fighting finally ceased in the Kuril Islands, the Eleventh US Army Air Force, sent between August 24th and September 4th, 1945 two B-24s of the 28th Bomb Group who flew reconnaissance over flights over the North Kuril Islands to take photos of the Soviet occupation in the area. P-63 Soviet fighters were scrambled to intercept the American B-24's and forced them away - no doubt a foretaste of the Cold war that lay ahead.
