Russia flexes nuclear muscle with 8,700-mile cruise missile test

Russia has announced a significant test of its experimental nuclear-powered cruise missile, the 9M730 Burevestnik (NATO codename SSC-X-9 “Skyfall”), claiming it flew nonstop for 15 hours over approximately 8,700 miles (14,000 kilometers) powered by a compact onboard nuclear reactor. This test, disclosed on October 21, 2025, was publicized alongside large-scale Russian nuclear drills and touted by state media as evidence of advanced development. However, no independent verification—such as satellite imagery or international monitoring—has confirmed the flight, and Western defense officials remain skeptical, viewing the announcement more as a demonstration of resolve than a confirmed technical breakthrough. Past Burevestnik tests have been inconsistent, including a 2019 accident at the Nyonoksa test range that caused fatalities and a radiation spike, linked to the missile’s development. The Burevestnik revives Cold War-era concepts, drawing inspiration from the U.S. Project Pluto of
