that's the MiG-25. MiG-31 is the refined version of the MiG-25, which was built in a rush because the Soviets thought we (America) were gonna have a mach 3 capable nuclear bomber soon and they didn't have anything that could compete with that, so they slapped engines meant for a cruise missile onto an interceptor that didn't have a tough enough airframe to handle the high speeds. MiG-31 isn't plagued by the problems that plagued the MiG-25.
