The worlds largest submarines are the Russian 941 Akula (designated 'Typhoon' by NATO) class. The launch of the first at the secret covered shipyard at Severodvinsk in the White Sea was announced by NATO on 23 Sep 1980. The vessels are believed to have a dived displacement of 26,500 tonnes (58.422 million lb), to measure 171.5 m (562 ft 7 in) overall and to be armed with 20 multiple warhead SS-N-20 missiles with a range of 8300 km (4500 nautical miles).
