Russia’s Khabarovsk nuclear submarine has reportedly entered the water for testing in the White Sea, near Finland — according to The Barents Observer and Russian military bloggers.

This is no ordinary submarine: it is believed to be designed to carry Poseidon nuclear‑powered torpedoes, one of Russia’s most controversial strategic weapons.
Why Khabarovsk matters

Poseidon torpedoes are described as:
nuclear‑powered
long‑range

autonomous
intended for use after initial nuclear strikes
capable of generating a radioactive tsunami to devastate coastal cities

Hence the nickname: “doomsday weapons.”

What we know

First launched in November.
Now undergoing tests in the White Sea.
Intended for the Pacific Fleet.

Estimated to carry six Poseidon torpedoes.
Under construction since 2014.
Originally planned for completion in 2020.
Russia s defense minister called the launch “significant,” saying the submarine is designed to carry “missile weapons for various purposes.”

More submarines coming

Orenburg, a sister ship, began construction last year for the Northern Fleet.
A third vessel is planned, with no timeline disclosed.

The strategic impact

Khabarovsk represents Russia’s push to field a new class of underwater strategic deterrent — difficult to intercept, difficult to detect, and designed to create maximum psychological and military presure.

As analyst H.I. Sutton notedIts unique capabilities could change the nature of underwater warfare.”
