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 design, which included features like a supercharger and a high power-to-weight ratio, making it suitable for high-performance applications. Despite its innovative design, the Junkers Jumo 222 faced production challenges and was never mass-produced. Only a limited number of prototypes were built, and it ultimately did not see widespread use in the war, overshadowed by other more successful engines of the time.
