Typhoon class
Typhoon class is a nuclear-powered submarine operated by Soviet Navy, powered by 2 OK-650, twin of about 190 MWt each. Retired.
The largest submarines ever built, at 48,000 tonnes submerged, more than double an Ohio-class boat, with twin reactors and a design that let the crew live in genuine comfort by submarine standards on the theory that patrols would run for months. All are now retired or scrapped except one kept for missile testing.
