However, the Soviet Union, and then Russia, did not complete the program to create the improved MiG-31M. The reason for this was the powerful economic crisis that was observed in Russia in the 90s, writes Rossiyskaya Gazeta with reference to Military Watch.

The authors of the material noted that the original MiG-31 was the first fourth-generation combat aircraft in the USSR. And now it can be called one of the best among those put into service. The MiG-31M also expanded the capabilities of the original version. He meant an increased maximum take-off weight. That is, the plane could take on board more fuel and weapons. The fighter would also have a new Zaslon-M radar. The MiG-31M could intercept hypersonic missiles. In addition, the airplane’s airframe would be more streamlined.

The program, however, was curtailed in 1995.
