BATTLEFORWORLD.COM | May 13, 2026: This type of defense is referred to by some as an 'oceanic shield', and it's referring to Russia's doomsday torpedo that is now at sea, on active duty. - The Russian Navy has launched its most secretive and strategic submarine yet - RFS Khabarovsk - a nuclear-powered special-purpose vessel built for one mission only: to carry and deploy Poseidon (Status-6) nuclear torpedoes.

This sea weapon is called 'Poseidon' and some of its features are:
▪️It's a nuclear-powered, autonomous underwater torpedo
▪️With an estimated range of up to 6,200 miles - intercontinental distance
▪️The weapon is capable of carrying a 2-megaton nuclear warhead - 100x more destructive than the Hiroshima bomb
▪️Operates at depths and speeds that make interception extremely difficult

President Vladimir Putin himself saw one of this type of torpedo tested successfully in October 2025, and called it "a huge success" and said "there is nothing like this".

The submarine 'Khabarovsk' was built to carry several Poseidon torpedo, and some of its features include:
▪️ A nuclear-powered special-purpose submarine that was quietly launched by the Russian Navy
▪️ Designed to carry up to 6 Poseidon torpedoes in specialized side-mounted launch hangars
▪️ Powered by a single OK-650V nuclear reactor
▪️ Operates from protected bastion zones near Russian coastlines - safely out of enemy reach - while Poseidon autonomously travels to its target
▪️ No countermeasure exists to intercept it

Poseidon is Moscow's direct hedge against the United States missile defense, precision-strike capabilities, and low-yield nuclear systems that Russia views as a threat to its strategic stability. The Russian system is integrated with the Perimeter dead-hand system, allowing Poseidon to guarantee retaliation even if Russia's nuclear command and control is destroyed.

Russia's plan, according to the US Naval Institute, calls for the deployment of 30 Poseidons on 4 submarines - 2 for the Northern Fleet, 2 for the Pacific Fleet - with torpedoes in the Atlantic and Pacific capable of autonomously striking US port cities, far beyond the effective reach of any American torpedo.

As a multipurpose deterrent - the Poseidon is a dual-capable, conventional or nuclear, and is built to strike carrier battle groups, coastal fortifications, and critical infrastructure.

The United States has no standoff weapon system to intercept Poseidon. Its Navy retired Subroc in 1992 - its only long-range anti-submarine missile. Its replacement, Sea Lance, was eventually canceled at the end of the Cold War and never replaced.

Russia's Doomsday Torpedo, the Poseidon, is now at sea on combat duty.
