A single submarine could destroy a country. First, we have to know that the Typhoon class is nuclear-powered submarines. They are the largest submarine ever built. This submarine is a multi-hold vessel. This means it has five inner hulls, all placed inside a superstructure of two parallel main hulls. Do you know that the surface of the superstructure is coated with sound observant tiles? This submarine has the ability to travel under the ice. Due to its terrific design it can also break down the ice. The maximum diving depth of the submarine is 1,312 feet. It runs at the speed of 12 knots when surfaced in 25 knots when underwater. Typhoon class submarines are also able to stay at sea for up to 120 days. The submarine carries 20 plastic missiles. Each missile consists of 10 independently targeting warheads. Each missile with the capacity of 110 kiloton nuclear warheads. Do you know that the bomb dropped on Hiroshima? Japan in World War II was 14.3 kilotons. Now can you imagine that how much damage this submarine can do? Thanks for watching.
