The Junkers Jumo 222 was a German aircraft engine developed during World War II. It was a liquid-cooled, V-12 engine designed for use in various military aircraft. The engine was notable for its advanced features, including a supercharger and a high power-to-weight ratio, which made it suitable for high-performance applications. Despite its innovative design, the Jumo 222 faced production challenges and was not widely used in combat. Only a limited number of prototypes were built, and it ultimately did not achieve the operational success that was initially anticipated.
