Why did MIG -25 stop production? What's wrong with it?

Because this thing is totally rubbish. The normal flight state that claims to be fast but actually has no afterburner is subsonic. Like other fighters, it has poor maneuverability, zero combat capability and no ability to attack the ground. Only under the guidance of its own ground radar can missiles be launched at predetermined positions for interception. The high speed can only be slowly accelerated to the so-called maximum speed of Mach 2.8 by continuously turning on the scrapped engine, and it can only be achieved instantly because of fuel restrictions. The empty weight of 22.5 tons and the maximum takeoff mass of more than 40 tons are just 20 tons of afterburner thrust, original aerodynamic shape and more primitive electronic equipment, which doomed the tragedy of MIG25. At that time, the Soviet Union YY, the West was very scared. As a result, the myth of MIG-25 became a big joke handed down from generation to generation in the world military field after Captain belenko defected to the Japanese Han Pavilion in 74.
