The P-63C-5 Kingcobra was an American single-engine fighter used during World War II. It was supplied to the Soviet Union in large numbers through the Lend-Lease program between 1943 and 1945. Developed from the P-39 Airacobra, the P-63 featured a redesigned wing with reduced aerodynamic drag, a forward-shifted fuselage, and a four-bladed propeller. The P-63C series differed from the P-63A-5 by having a more powerful Allison V-1710-117 engine and a wingspan that was reduced by 10 inches. The C-5 variant also had two additional wing hardpoints for 500-pound bombs and a ventral fin beneath the tail to improve directional stability. A total of 3,273 P-63s were built between 1943 and 1945, including 1,227 P-63Cs. Approximately 2,400 of these aircraft were delivered to the Soviet Union. These fighters saw active service with the Soviet Air Forces during the Great Patriotic War.

The Soviet P-63C-5 was introduced as one of the rewards for the 2016 "War Thunder Fulfills Your Wishes!" event. With an excellent rate of climb, good maneuverability, and powerful armament, the P-63C-5 is well suited for air combat, especially at higher altitudes. However, its effectiveness in combat is negatively affected by vulnerable fuel tanks located in the wings and rapid speed loss during hard turns.
