Russia is preparing to deploy the Poseidon nuclear torpedo aboard the specialized nuclear-powered submarine Khabarovsk. According to AT, the emergence of such a carrier could seriously alter the balance of power in underwater defense, strengthen Russia’s strategic capabilities and send a tough signal to the United States. The outlet notes that Moscow’s move could push nuclear rivalry into a new stage in the maritime sphere.

According to Naval News, Russia’s Poseidon program has advanced with the construction of the Khabarovsk nuclear submarine. The submarine is currently undergoing technical outfitting in Severodvinsk on the White Sea. Its length is estimated at about 135 meters, and its design is said to combine features typical of Borei-class submarines with elements of Poseidon’s first carrier, the Belgorod nuclear submarine.

It is believed that Khabarovsk will be able to carry up to six Poseidon torpedoes housed in side compartments. The submarine is expected to be equipped with an OK-650V nuclear reactor, while increased stealth and survivability are listed among its key characteristics.

A Western report published in September 2021 described Poseidon as a large autonomous nuclear torpedo capable of reaching speeds of up to 70 knots. Thanks to a miniature nuclear reactor, the weapon is said to have virtually unlimited range and to be able to dive to depths of up to one kilometer. Such depth would make it unreachable for existing crewed submarines.

Russian officials describe Poseidon as a multipurpose system designed to strike carrier groups, coastal fortifications and infrastructure facilities.

Military expert Norman Polmar, in an article for Proceedings in January 2026, suggested that Russia may build 30 Poseidon torpedoes. In his assessment, they could be deployed on four submarines: two with the Northern Fleet and two with the Pacific Fleet.
