How much does a submarine weigh?

The Typhoon class submarine is a type of nuclear-powered ballistic missile submarine deployed by the Soviet Navy in the 1980s. With a maximum displacement of about 26,000 tonnes surfaced (about 48,000 submerged), Typhoons are the largest class of submarine ever built. Compare that to the small, manned submarines used for ocean exploration. Some of these submersibles weigh under a ton. There's a fairly wide range of sizes and weights between the smallest and largest boats.
