The Typhoon Class SSBN

The largest submarine ever deployed was the Russian Typhoon class ballistic missile submarine during the late period of the Cold War. It had luxurious facilities for the crew so they could remain happy and satisfied during long deterrence patrols or nuclear war. The Russians decommissioned the Typhoon class in the late 2000's and replaced it with the smaller Borie class SSBN.

Good information on the Typhoon class submarine. This diagram does a great job of showing it's armament of ballistic missiles and tactical torpedoes, however it would be nice if it showed a cross section of what the submarine looked like in side.

This is a picture of the indoor swimming pool aboard the Typhoon class submarine. It is one of the luxurious facilities available for the crew.
