So far, very little is known about the aircraft that Russia wants to build, the MiG-41.

If realized, it will have a ramjet or turboramjet engine and will be able to develop a speed of up to Mach 5.

It will be able to fly at a very high altitude and will carry rockets for satellites. It will still be able to hit hypersonic missiles (speed between 5 and 25 Mach).

But the future will prove whether Russia will be able to make it a reality.
