Russia's Typhoon-Class Submarine Could Kill Millions and Had a Swimming Pool

Summary: The Russian Navy decommissioned the Dmitry Donskoy, a Typhoon-class nuclear-powered ballistic missile submarine, in February 2023, earlier than initially planned. Originally commissioned in 1981 as TK-208 and later renamed, this submarine was the lead vessel of the Project 941 Akula class. It is the largest ever and something in terms of size the U.S. Navy never chose to match. 

-Known for its significant size and capabilities, it was the last of its class to remain in service, serving primarily as a test platform for advanced submarine classes like the Borei and Yasen. The Dmitry Donskoy played a crucial role in the development and testing of the Bulava ICBM following an extensive upgrade under Project 941UM.

-With the retirement of this iconic submarine, which once boasted amenities such as a sauna and a small swimming pool for its crew, the era of the Typhoon-class submarines, designed as a Soviet counterpart to the U.S. Ohio-class, has effectively ended. A new Borei-class submarine, continuing the legacy, is set to be named after the historic figure Dmitry Donskoy.

Over a year ago, Russia decommissioned the Project 941 Akula (NATO reporting name Typhoon) heavy nuclear-powered missile-carrying submarine cruiser Dmitry Donskoy several years earlier than expected. In fact, it had been only three years ago that the Kremlin announced the boat would remain in service until at least 2026, even as its role was reportedly limited to that of a weapons test platform for the new Borei-, Borei-A-, Yasen-and Yasen-M-class submarines.

In February 2023, it was officially confirmed that Dmitry Donskoy was decommissioned in February due to cost considerations. The submarine had served for more than 40 years in the Northern Fleet.

Initially designated the TK-208, she was the lead vessel of the Soviet third-generation Akula-class (Russian for "Shark"). She entered service in 1981 with the Soviet Navy, and after a 12-year overhaul and refit that began in 1990, she reentered service in 2002 as the Dmitry Donskoy, named after the Grand Duke of Moscow Dmitry Donskoy (1359–1389), the reputed founder of Moscow.

According to Russian media, Dmitry Donskoy initially carried D-19 strategic intercontinental ballistic missiles (ICBMs) as its basic armament. Following its upgrade under Project 941UM, it was involved in the tests of the seaborne Bulava ICBM.

Typhoon-Class: Project 941 Boats

The Sevmash Shipyard built six of a planned seven Project 941 submarines for the Russian Navy, and all were operational with the Northern Fleet. Though the oldest of the submarines, the Dmitriy Donskoy was also the last of the class to remain in service.

The TK-202, TK-12 – later renamed the Simbirsk – and T-13 were withdrawn from active service between 1996 and 2009, and scrapped with the financial support of the United States. Two other boats: the TK-17/Arkhangelsk and TK-20/Severstal remained in service until they were decommissioned circa 2013. A seventh boat, TK-210, was laid down but scrapped before completion.

With a displacement of 48,000 tons, a length of 175 meters (nearly 600 feet), a 23-meter beam, and a 12-meter draught, the Typhoon-class was the largest class of submarines ever built. Developed with multiple pressure hulls, including five inner hulls situated inside a superstructure of two parallel main hulls, the Typhoon-class was also wider than any other submarine ever built. The submarines were powered by OK-650 pressurized-water nuclear reactors, two 50,000 horsepower steam turbines, and four 3,200 KW turbogenerators and this provides the boat with the ability to sail at a speed of up to 22.2 knots on the surface and 27 knots whilst submerged.

Each contained nineteen compartments, including a strengthened module, which housed the main control room as well as an electronic equipment compartment above the main hulls and behind the missile launch tubes. It even was reported that there was a sauna on board as well as a small swimming pool for the crew. The sheer size of the submarines was likely welcomed by the approximately 160 sailors who called the submarine home on voyages lasting 120 days or longer, oftentimes without surfacing for months at a time.

The Typhoon-class subs were designed to counter the United States Navy's Ohio-class subs, which were capable of carrying up to 192 100-kiloton nuclear warheads. By contrast, the Soviet Typhoons could carry a primary cache of 20 RSM-52 SLBMs (submarine-launched ballistic missiles), each of which contained up to 10 MIRV (multiple independently targetable reentry vehicle) warheads.

Though the Dmitriry Donskoiy has been decommissioned, in 2021, a new sub of the Borei-class has already begun construction; and when launched, will bear the name of the legendary founder of Moscow.
