7,636 tons
The weight of an average submarine can vary significantly depending on its type and purpose. A typical military submarine can weigh anywhere from 1,500 tons for smaller, diesel-electric submarines to over 18,000 tons for larger nuclear-powered submarines. For example, the U.S. Navy's Virginia-class submarines weigh around 7,800 tons. In contrast, smaller research or tourist submarines can weigh as little as a few tons.
Sorry, but that information is classified.
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.
Cyclops Nuclear Submarine Captain was created in 1991.
It is indeed.
A nuclear submarine has a reactor . There is no liquid fuel at all.
