Unmanned Undersea Vehicles and Guided Missile Submarines

Book excerpt: During the Cold War the United States developed the Trident class ballistic missile submarine (SSBN) to replace the aging fleet of forty-one Poseidon ballistic missile submarines. Each of the eighteen Trident class submarines built to carry the mantle of strategic nuclear deterrence was extremely large and quiet with tubes for twenty-four ballistic missiles. Following the breakup of the Soviet Union and the end of the Cold War, the United States conducted a review of its nuclear posture, which determined that only fourteen of these submarines were necessary to meet the needs of U.S. national security. Since these submarines are due for nuclear core refueling and overhaul and thus are no longer required to support U.S. nuclear policy, these submarines will be deactivated or refueled and converted to other purposes. These submarines are only halfway through their design life of forty-two years, and once refueled could be used for other missions. Furthermore, their large size makes these ships a prime candidate for conversion to a large variety of missions that require space, stealth, and endurance, This excess capability has convinced the U.S. Navy that it should develop a concept for converting the first four Trident class ballistic missile submarines into guided missile submarines (SSGN). This program would equip these submarines both for cruise missile operations and as special operations force insertion platforms. Each submarine could carry more than 100 Tomahawk cruise missiles and up to sixty-six special operations personnel with dual Dry Deck Shelter or two Advanced SEAL Delivery System mini-submarines for SEAL deployment.
