Putin Hails Poseidon Nuclear Underwater Drone Test as Trump Orders U.S. Nuclear Testing to Resume

Overview

• Vladimir Putin said Russia activated the Poseidon’s onboard nuclear propulsion during a submarine-launched test and claimed the system cannot be intercepted.
• Russia earlier reported a successful test of the nuclear-powered Burevestnik cruise missile, framing both demonstrations as strengthening deterrence.
• President Donald Trump announced on Truth Social that he directed an immediate restart of U.S. nuclear weapons testing, citing other countries’ programs; the last U.S. test was in 1992, according to Reuters.
• China urged Washington to honor the Comprehensive Nuclear-Test-Ban Treaty, while the Kremlin protested it was not notified, denied conducting nuclear tests, and warned Russia would abandon a moratorium if others do.
• Analysts say Poseidon is a large nuclear-powered undersea vehicle potentially capable of causing severe coastal contamination, though many technical claims remain unverified by independent sources.
