Russia’s Huge, Nuclear Armed Typhoon-Class Sub -The Most “Feared” Weapon of the Cold War

Russia’s Typhoon class nuclear-armed submarines may not serve anymore, but they are referred to as one of the most “feared” weapons during the Cold War. Although the submarines are no longer actively patrolling the Northern Seas, they remain the world’s largest submarine ever to exist.

Sizeable Adversary

Not only were the Typhoon class submarines nearly two football fields long at 574 ft, but the weapons they threatened the West with were extremely substantial and lethal. The Typhoon submarines could carry up to twenty long-range ballistic missiles with, as an interesting article from the Federation of American Scientists describes it, “200 nuclear warheads that were once aimed at the United States.”

“The submarine (Typhoon) is equipped with the D-19 launch system with 20 solid-fuel propellant R-39 missiles which have a range of up to 10,000 km. They are arranged in silos in two rows in front of the sail between the main hulls. The Typhoon has an automated torpedo and missile loading system including 6 torpedo tubes with calibres of 650 and 533 mm,” the FAS essay states.

Ballistic Threat

R-39 RiF nuclear weapons presented a significant threat to the U.S. and NATO given that they could fire from ranges up to 8,200 miles and hold U.S. targets at risk from more than 5,000 miles away. Depending upon which dark corners of the undersea Typhoon submarines were lurking in, they certainly could hold vital U.S. targets at risk. Specifics listed in say the R-39s operate with as many as 10 Multiple-Reentry Vehicles capable of delivering a 200 Kiloton warhead.


However, despite the significance of the threat they present, the R-39 armed Typhoon-class submarines were not as threatening as the U.S. Navy’s Ohio-class ballistic missile submarines, which could fire as many as 24 Trident II D5 submarine-launched nuclear missiles out to ranges beyond 6,500 miles.

This slight disparity did not make a huge difference in many respects, given that the Typhoon class submarines were specifically built to operate as part of Russia’s Northern fleet, meaning they would patrol the Northern Sea Route bordering the Arctic and operate in the Baltic Sea. As part of this strategic focus, the Typhoons were engineered for ice-breaking and traveling beneath the ice. The FAS report explains that the Typhoons operated with floating antenna buoys in order to network satellite navigation details and targeting designations from beneath the ice.

“The Typhoons are equipped with the ‘Slope’ hydroacoustic system that consists of four hydroacoustic stations. The ‘Slope’ system allows to track 10-12 vessels simultaneously. It also employs two floating antenna buoys to receive radio messages, target designation data and satellite navigation signals at great depth and under an ice cover,” FAS states.

A surprising element of the Typhoon-class boat is that, despite its massive size, it was actually somewhat quiet and stealthier than many smaller submarines. Coating materials and shock-absorption can reduce the acoustic signature of the boat.

“To reduce the acoustic signature a two-spool system of rubber-cord pneumatic shock-absorption is employed as well as a block layout of gears and equipment, a new sound isolation and andrihydroacoustic coating,” FAS writes.

Despite presenting this kind of threat, Russia’s Typhoon-class modernization program was canceled in 2012 due to cost reasons, as the Borei-class was reportedly cheaper.
