The Typhoon class submarine (NATO name) is a nuclear-powered ballistic missle submarine deployed by the Soviet Navy in the 1980s. With a maximum displacement of 26,000 tonnes, Typhoons are the largest class of submarines ever built. The Typhoon class was developed under Project 941 as the Russian Akula (shark) class. Typhoon submarines are among the quietest sea vessels in operation, being quieter and yet more maneuverable than their predecessors. This is partly due to the vessels‘ large size, which allows them to minimize noise caused by water. It is 175 meters long which makes it longer than a soccer field, it’s 8 stories high, has nuclear reactors a size of a bus and needs 163 crew members to run it… Here is a picture of one caught on Severodvinsk beach, as well as Russian news report about it
