Russia Launches Nuclear Submarine to Carry ‘Doomsday’ Poseidon Drone

• Russia has unveiled its newest nuclear-powered submarine, “Khabarovsk,” designed to deploy the Poseidon nuclear-capable underwater drone , often described as a “doomsday missile.” The launch marks a significant milestone in Moscow’s efforts to strengthen its underwater nuclear deterrence and expand its strategic capabilities amid rising global military tensions.

Launch Ceremony at Sevmash Shipyards

• The “Khabarovsk” was launched at the Sevmash shipyards in Severodvinsk , one of Russia’s key naval production facilities. The ceremony was attended by Defence Minister Andrei Belousov , Naval Chief Admiral Alexander Moiseyev , and senior defence officials. Belousov hailed the launch as “a defining moment” for Russia’s navy, emphasizing its role in safeguarding the country’s maritime interests. Sevmash is also known for having retrofitted India’s INS Vikramaditya aircraft carrier, underscoring its global defence significance.

Strategic Role and Technical Features

• Developed by the Rubin Central Design Bureau of Marine Engineering , the “Khabarovsk” is a heavy nuclear-powered missile cruiser built to operate advanced underwater systems, including robotic and nuclear-armed platforms. The submarine is engineered to carry and launch Poseidon drones , giving Russia a unique second-strike capability that can operate autonomously at intercontinental ranges. According to the Russian Defence Ministry, the vessel will help “secure Russia’s maritime borders and national interests across global waters.”

Poseidon Drone: Russia’s Underwater Superweapon

• The Poseidon drone , successfully tested in October 2025 , represents one of the most advanced weapons in Russia’s arsenal. Powered by a miniaturised nuclear reactor , it can travel thousands of kilometres underwater at high speeds and great depths, making it nearly impossible to intercept. Russian officials, including President Vladimir Putin and Deputy Security Council Chairman Dmitry Medvedev , have highlighted its potential to cause catastrophic underwater explosions, capable of devastating coastal infrastructure.

Geopolitical and Defence Implications

• Military analysts view the Khabarovsk–Poseidon system as a part of Russia’s strategy to enhance second-strike nuclear capability and deter maritime threats from NATO and other adversaries. The introduction of autonomous nuclear drones signals a new phase in global deterrence and underwater warfare technology. It reinforces Moscow’s intention to maintain technological and strategic dominance beneath the world’s oceans.
