S/P500 не упадёт а грохнется.

Сергей Юрьевич, Russia has successfully tested the S-550 air defense system, Russian military sources reported on December 28. The new system is derived from the S-500 Prometheus but will be capable of hitting ICBMs and satellites. It is another step toward building a Russian offensive space capacity that is dangerous to U.S. items orbiting around the Earth. 
Also in Sochi, a decision must have been made to conduct a test of a Russian anti-satellite system, known as Nudol. Two weeks later, it destroyed Cosmos-1408, a defunct Soviet satellite, in orbit, leaving behind a cloud of debris that Western nations, including the United States, said would pose a threat to the International Space Station (ISS).
