The USS Seawolf Class submarine Jimmy Carter has a 12,150 ton displacement, can dive incredibly deep, reaching speeds approaching 40 knots, and is armed with 50 weapons and wide 660mm torpedo tubes.
USS Jimmy Carter is roughly 100 feet (30 m) longer than the other two boats of her class due to the insertion of a section known as the Multi-Mission Platform (MMP), which allows launch and recovery of ROVs and United States Navy SEALs forces. The MMP may also be used as an underwater splicing chamber for tapping of undersea fiber optic cables. This role was formerly filled by the decommissioned USS Parche (SSN-683). Jimmy Carter was modified for this role by General Dynamics Electric Boat at the cost of $887 million.
