US Navy's New Nuclear Submarine Shocked the World - There are three major types of submarines in the United States Navy: ballistic missile submarines, attack submarines, and cruise missile submarines. All submarines in the U.S. Navy are nuclear-powered. Ballistic missile submarines have a single strategic mission of carrying nuclear submarine-launched ballistic missiles. Attack submarines have several tactical missions, including sinking ships and subs, launching cruise missiles, and gathering intelligence.
The submarine has a long history in the United States, beginning with the Turtle, the world's first submersible with a documented record of use in combat.
Montana is the fourth largest state in size, but the eighth least populous in the country. It is also quite a way from the sea, but now the future Virginia-class submarine USS Montana (SSN 794) will honor the Treasure State. This past weekend the U.S. Navy christened the fast-attack submarine at Huntington Ingalls Industries (HII) Newport News Shipbuilding Division. Construction of the boat began in 2015, and the submarine will be delivered to the U.S. Navy late next year.
