How does Russia's nuclear missile work? KHA-555

This is the Kha-555 Light Precision Strategic Cruise Missile and it is designed to stealthily destroy strategically important targets.
Kha-555 - has several modifications, one of them: it is a 200 kt nuclear warhead missile.

Its range is up to 2,500 kilometers (about 1,550 miles) Being launched from frontier cities like Pskov, the missile is capable of attacking almost all of western Europe.

The Kha-555 has a reduced effective scattering surface, making it less visible to radar. The Kha-555 missile flies at speeds of 447-516 mph at extremely low altitudes with terrain envelopment.

Kha-555 has a streamlined stealth shape, The principle of stealth technology is that radio waves are reflected away from the transmitter. Part of the signal is absorbed by special coatings, and the rest is reflected so that the radio echo does not return to the airspace scanner.
As a result, for a radar, a missile is comparable to a small bird in terms of the number of reflected waves.

Since the missile is launched from Tu-95MS Tu-160 aircraft, this could allow the missile to be launched on the approaches to the United States and attack U.S. border areas.
