The Ye-155, the prototype of the MiG-25, a Mach 3 capable interceptor and reconnaissance platform, makes its first flight. Later given the NATO reporting name “Foxbat,” the MiG-25 is developed in response to the US development of the B-70 bomber. The B-70 project is limited to research prototypes, but development of the MiG-25 continues. About 700 MiG-25s are eventually built.
