Hypersonic weapon

Typical Low Earth Orbit atmospheric re-entry speed is Mach 25.

[2] At such speed, the molecules of the atmosphere disassociate into a plasma which makes control and communication difficult.

The Silbervogel was the first design for a hypersonic weapon and was developed by German scientists in the 1930s, but was never constructed.

The Kremlin presents new hypersonic weapons as supposedly capable of overcoming "any" foreign missile defense systems, with the "pre-nuclear deterrence" concept contained in its 2014 iteration of the official Russian Military Doctrine.
