Cold as Ice?
Russia’s Typhoon-class submarines were true Cold War leviathans.
The missile-firing submarines were designed to operate in the Arctic under pack ice.
A typical Typhoon was more than 1.5 times longer than a football field and three times as tall as the average American house.
In the 1970s, the Soviet Union embarked upon a new nuclear weapons program (code name: Typhoon) to develop a new missile-firing submarine and nuclear missiles. The subs (code name: Akula) were designed to be 566 feet long, ( a football field in the USA is 360ft long & 160ft wide) 76 feet wide, and nearly 38 feet tall.
The Typhoon-class submarines displaced 23,200 tons in order to accommodate a payload of 20 RSM-52 ballistic missiles. Although most subs are relatively spartan in amenities, the sheer size of the Typhoons made it possible for engineers at St. Petersburg’s Rubin Design Bureau to squeeze in such unprecedented perks as a solarium, swimming pool, and sauna.
Today, a newer generation of Russian missile submarines, the Borei class, are replacing the Russian Navy’s aging Typhoon- and Delta-class subs. The Borei-class subs carry 16 Bulava missiles for a total explosive yield of 7,200 kilotons, though the Bulava missiles are likely much more accurate than their predecessors.

Despite some delays in the program, it now appears that the Russian Navy will operate a total of eight Borei/-A-class ballistic missile submarines by 2022. These boats will form a core of the Russian nuclear triad until 2040. These boats are equipped with either one or two towed sonar arrays stored in tubes inside the vertical rudders that retract inwards. Additionally, there is also a noticeable bulge running alongside the hull for much of its length, which is likely a 'flank' sonar array. This array could allow the Borei-A-class to 'see' into the ocean with sonar in both the port and starboard directions.
The submarines are armed with sixteen Bulava ballistic missiles, a three-stage solid-propellant sea-launched variant of the Topol-M, which has a range of over 8,300 kilometers. (5,157 miles) It can reportedly be fitted with six to ten nuclear multiple warheads yielding 100 to 150 kilotons apiece, according to The Diplomat. In addition, the Bulava can be fitted with 10 to 40 decoy warheads. The Project 995A submarines are also furnished with 533mm torpedo tubes.
"According to NetEase publication, Russian nuclear submarine of the Borey project (according to other sources, it was an Akula project submarine), approached the US coast unnoticed. It was possible to establish the whereabouts of the nuclear submarine with up to 160 nuclear warheads on boards after the sub started going back to the base. A submarine of this class is capable of destroying most of the territory of the United States of America in minutes."
