Russia: Russia on Saturday launched the nuclear-powered submarine Khabarovsk, a vessel Moscow says is built to carry advanced underwater weapons and robotic systems, including the much-discussed Poseidon nuclear drone. The ceremony took place at the Sevmash shipyards in Severodvinsk and was attended by Defence Minister Andrei Belousov and Navy Chief Admiral Alexander Moiseyev.
Officials described the Khabarovsk as a heavy, long-range platform intended to bolster Russia’s maritime security and project power across distant waters. The submarine was developed by the Rubin Central Design Bureau of Marine Engineering and incorporates provisions to deploy new-generation underwater systems, the defence ministry said.
State and business media noted that Khabarovsk-class boats are expected to be primary carriers for the Poseidon, an autonomous nuclear-capable underwater drone. Russian authorities this week announced a test of a nuclear-powered Poseidon, and President Vladimir Putin hailed the trial as a success, saying the system’s miniature reactor functioned as intended during a limited run.
Domestic outlets have highlighted the Poseidon’s claimed attributes: high speed relative to conventional submarines and torpedoes, the ability to operate at great depths, and the capacity to travel long distances. Western and independent analysts, however, have repeatedly raised technical and legal questions about the weapon’s practicality and destabilising effects.
The launch ceremony at Sevmash also recalled the yard’s recent work for foreign customers, including previous retrofits of major carriers. Russian officials framed the event as a milestone in modernising their undersea arsenal and integrating robotic systems into naval doctrine.
International reaction to Moscow’s announcements has been mixed. Some Russian officials and commentators described the Poseidon as a strategic deterrent. Others abroad warned that deploying such systems would heighten maritime tensions and complicate arms control efforts. Investigations into the Poseidon’s technical feasibility and its implications for coastal security and international law continue among analysts.
Sevmash, the country’s largest shipbuilding complex, will now move the Khabarovsk into final outfitting and sea trials. The submarine’s full operational status and its timeline for Poseidon integration have not been publicly confirmed. Russian authorities say more details will follow as the vessel advances through testing and certification.
