High Quality Content by WIKIPEDIA articles! The Mikoyan-Gurevich I-270 was a response to a Soviet Air Force requirement in 1945 for a rocket-powered interceptor aircraft for the point-defence role. In concept and basic configuration, it was strongly reminiscent of the German Messerschmitt Me 263, and is generally regarded as a further development of that design. Only two prototypes were built, both of which were destroyed in crashes, leading to the cancellation of the project.
