What is the truth about the “Skyfall” or “Burevestnik” missile?

Technically, Burevestnik is one of the most interesting missile systems in the world. But otherwise, that missile is less advanced or less powerful than the Russians claim. The only thing that makes this kind of missile a hard target for defenders is its nuclear reactor. If a nuclear reactor is damaged, that system will deliver nuclear fuel, which can be highly enriched plutonium, into the falling area. This missile is otherwise one of the subsonic missiles. 

The nuclear reactor of Buresvestnik. 

The speed of that missile is maybe 800-1350 km/h, which makes it much slower than the 1950s Ling-Temco-Vought Supersonic Low Altitude Missile (SLAM), or “Project Pluto”. The SLAM missile speed was Mach 3+, and its range was also unlimited. The problem was the pollution line that followed that missile. The SLAM used an open reactor, which allowed air to flow through it. This caused a situation in the nuclear reactor. The radioactive core impacted with air. That caused a situation. That radioactive cloud followed that missile.

That means Burvetnik is maybe a little bit worse than the “Project Pluto” from the 1950s. The Burvestnik should also pull the radioactive particle line behind it. The only difficult thing. With the defense against the Burevestnik missile. This is how to deny radioactive material. Spread around the area if that kind of missile is shot down. But anyway, those kinds of systems are similar to other subsonic cruise missiles.
