Sufficient aircraft continued in use after the war for them to be given the NATO reporting name of Fred. By 9 May 1945, operational units had still 1,148 Kingcobras on strength. On 8 October 1950, two USAF F-80Cs from the 49th Fighter Group breached the USSR's border and attacked Sukhaya Rechka airfield south-west of Vladivostok and from the Soviet-Korean border, making two strafing runs before returning to their home base. Although Soviet sources claim the attack was intentional, the pilots claimed it was a result of a navigational error. The airfield belonged to the Air Forces of the Pacific Fleet (VVS TOF), but it was occupied by the 821st Fighter Aviation Regiment (821 IAP) of the 190th Fighter Aviation Division (190 IAD). Mostly aircraft of the 1st Squadron of 821 IAP were hit with 12 P-63s damaged, one P-63 burned to the ground while the other damaged aircraft were able to be repaired. No human losses were suffered.
