Columbia-class ballistic missile submarines (SSBNs) are being constructed by General Dynamic subsidiary Electric Boat for the US Navy in collaboration with Newport News Shipbuilding. Newport News Shipbuilding cut the first steel plate for the lead submarine in class, Columbia (SSBN 826), in May 2019. The boat is scheduled to be delivered in 2027 . The subs are 560 feet in length with a beam of 43 feet. The class is being constructed with a life-of-ship reactor, which will result in a shorter mid-life maintenance period. Each of the boats is designed to serve a forty-two-year service life

Columbia-class submarine The Columbia-class submarine, formerly known as the Ohio Replacement Submarine and SSBN-X Future Follow-on Submarine, is a future United States Navy nuclear submarine class designed to replace the Trident missile -armed Ohio -class ballistic missile submarines The Navy today awarded a $9.47 billion contract modification to General Dynamics Electric Boat to officially start construction on the first ballistic-missile submarine in the Columbia class of SSBNs The Columbia-class submarine will be powered by electric-drive propulsion. It will use a nuclear reactor to generate energy, which will be converted into electrical power to fuel the electric propulsion motor. The submarine will be able to sail at a speed of more than 20 knots (37 km) and operate at a depth of 800 feet (250 m). The Columbia-class design includes 16 SLBM (Submarine-Launched.

WASHINGTON ― The Pentagon is asking Congress for authority to buy two of its new Columbia-class ballistic missile submarines, a potential mega-deal worth as much as $17.7 billion with far-reaching implications for the ailing submarine industrial base.. If approved, the proposal would potentially lower the price by promising General Dynamics a steady stream of work at its shipyard as the. The detailed design of the Columbia-class started in 2011, and lead-ship delivery is planned for 2027, a whopping 16 years. Here are some issues from the GAO on cost estimating: The Navy anticipates that it will need 12 million labor hours to directly construct the lead submarine—referred to as touch labor. This represents 17 percent fewer.
