MOSCOW, October 30, 2025: Russian President Vladimir Putin announced on Wednesday that Russia had successfully tested its nuclear-powered underwater drone, the Poseidon, marking a significant step in the country’s strategic weapons development program. The Kremlin confirmed that the test took place on Tuesday and involved the activation of Poseidon’s nuclear propulsion system during a trial launch from a Russian Navy submarine.

Speaking at a defense briefing in Moscow, President Putin said the Poseidon is unmatched globally in both operational depth and underwater speed. He stated that the system possesses no equivalent in terms of design or performance, describing it as capable of traveling at extraordinary depths and speeds without the possibility of interception. The Russian leader added that the weapon’s capabilities represent a major advancement in the country’s deterrence arsenal.
The Poseidon, also known by its designation 2M39, is a nuclear-powered unmanned underwater vehicle developed to carry either conventional or nuclear warheads. According to the Russian Ministry of Defense, the system is designed to operate autonomously and can travel intercontinental distances underwater. It was first unveiled publicly in 2018 as part of a new generation of “strategic superweapons,” alongside the Avangard hypersonic glide vehicle and the Burevestnik nuclear-powered cruise missile.
Russian defense officials stated that the recent test involved verifying the performance of the submarine-launched vehicle’s propulsion system and control mechanisms. The ministry said the results confirmed the stable operation of Poseidon’s nuclear reactor, which powers the drone and enables it to travel at speeds and ranges far beyond those of conventional torpedoes. The test was reportedly conducted in the Arctic waters, where Russia has expanded military testing and infrastructure over the past decade.

President Putin emphasized that the successful trial demonstrates Russia’s ability to advance complex military technologies despite international sanctions and geopolitical pressures. The development of Poseidon is part of a long-term modernization program aimed at enhancing the capabilities of Russia’s strategic deterrent forces. The system is being integrated into the Northern Fleet’s arsenal, with plans to deploy it on specially modified submarines, including the Belgorod and Khabarovsk.
According to publicly available information from the Russian military, the Poseidon measures approximately 20 meters in length and has an estimated operational range exceeding 10,000 kilometers. Its nuclear propulsion system allows for extended underwater endurance, while its depth capabilities make detection and interception difficult using existing anti-submarine warfare systems. Military analysts have noted that the drone’s design enables it to carry a warhead powerful enough to destroy coastal infrastructure or naval bases if deployed in a combat scenario.
The announcement follows another recent weapons test reported by Russian authorities involving the Burevestnik, a nuclear-powered cruise missile that also uses a reactor-based propulsion system. Together, the tests underline Moscow’s continued focus on developing advanced strategic systems amid ongoing tensions with Western countries. The Kremlin has described these technologies as vital to maintaining the balance of power and ensuring national security.
NATO response pending after Moscow confirms weapons test
The United States Department of Defense said it was aware of Russia’s announcement but declined to comment on operational assessments. NATO officials have not yet issued a formal statement regarding the test. The development of nuclear-powered underwater and missile systems has been closely monitored by international security organizations due to their potential impact on arms control agreements and global stability.
The Poseidon program remains one of the most closely guarded elements of Russia’s military modernization efforts. Wednesday’s announcement marks the first confirmed activation of the system’s nuclear propulsion unit during a full-scale test, signifying a milestone in its technical progress. Russian authorities said additional testing will continue under the supervision of the Ministry of Defense before the weapon enters operational readiness. – By Eurasian Newswire News Desk.
