Mikoyan-Gurevich I-270

The Mikoyan-Gurevich I-270 (Design Ж ("Zh") under Mikoyan-Gurevich's in-house designation sequence, USAF/DoD designation: Type 11) was a response to a Soviet Air Forces requirement in 1945 for a rocket-powered interceptor aircraft for the point-defence role. In concept and basic configuration, it was related to the early Korolyov RP-318 rocket-powered aircraft which was developed in 1936 and first flew February 20, 1940, and the more recent Bereznyak-Isayev BI-1 Soviet design. Only two prototypes were built, both of which were destroyed in crashes, leading to the cancellation of the project.
