MiG15bis

The MiG-15bis is a late variant of the Soviet MiG-15 fighter, developed by Mikoyan-Gurevich and introduced in the early 1950s as an improved follow-on to the original MiG-15. It was designed to provide better performance, range, and one of the more capable air-interceptor platforms of its era.

The aircraft features a more powerful Klimov VK-1A jet engine, an upgraded compressor, and refinements to the airframe and aerodynamics. These changes produced improved takeoff and climb performance and better high‑altitude handling. Increased fuel capacity and optimized systems also extended range and mission endurance.

Armament on the MiG-15bis typically comprised a heavy cannon assortment, commonly two 23 mm cannons and a single 37 mm cannon, delivering substantial firepower for engaging enemy aircraft and light ground targets.

Operational history of the MiG-15bis spans the Soviet Air Forces and numerous allied air forces during the early Cold War. It saw service in various regional conflicts and in encounters with Western aircraft in different theaters. Some air forces continued to operate the type into the late 1950s and into the 1960s, depending on national procurement cycles and replacements by more modern jets.

Production and legacy: The MiG-15bis remained part of the MiG-15 family’s export and service footprint, contributing to the widespread adoption of swept‑wing jet technology in the postwar period. It is remembered as a transitional, yet influential, design that helped shape early jet combat aviation.
