"This is an absolute breakthrough in both technology and defense," Peskov said.
On Sunday, Russian President Vladimir Putin announced that the Burevestnik missile had cleared the final test, calling it a unique weapon. Russian Chief of the General Staff Valery Gerasimov said it flew 14,000 kilometers (8,700 miles) in an October test flight. A test has demonstrated the missile’s ability to evade enemy missile defense systems, Chief of General Staff Gerasimov told President Putin.
Missile is powered by a miniature nuclear reactor, granting it virtually unlimited range.
Flying at ultra-low altitudes, it stays below radar, making interception nearly impossible.
