Columbia-Class Submarines
THE U.S. NAVY'S NEXT GENERATION BALLISTIC MISSILE SUBMARINE
The U.S. Navy's Columbia-class Ballistic Missile Submarines (SSBN) are currently under development. General Dynamics Mission Systems is responsible for the Columbia-class submarines' strategic weapons systems and subsystems.
The Columbia-class is the U.S. Navy's next generation ballistic missile submarine program. Once completed, the lead ship District of Columbia (SSBN 826) will be the quietest and most capable submarine ever built. General Dynamics Mission Systems is responsible for developing the Columbia-class' Trident II Fire Control System.
Currently Under Construction
At 560 feet long with a displacement of nearly 21,000 tons, the submarines of the Columbia-class will be the largest ever built by the United States.
General Dynamics Electric Boat is the prime contractor on the Columbia program, which will replace the aging Ohio-class ballistic missile submarines. Ships of the Columbia-class will have a fuel core that will power the submarine for its entire service life, eliminating the need for a mid-service refueling. In addition to its complement of missiles, the submarine will be armed with MK 48 torpedoes and will feature superior acoustic performance and state-of-the-art sensors.
The District of Columbia (SSBN 826) and Wisconsin (SSBN 827) are currently under construction.
Developing Columbia's Fire Control System
General Dynamics Mission Systems is responsible for the development, production and installation support of the Columbia-class' Trident II Fire Control System.
The Trident II is a Submarine Launched Ballistic Missile (SLBM) with a range of 4,000 miles. General Dynamics has designed, produced, installed, and sustained every version of the Fire Control System and guidance systems for Polaris, Poseidon, Trident I and Trident II missiles for more than 65 years.
General Dynamics will also deliver fire control systems for the U.K's new Dreadnought-class of ballistic missile submarines. In addition, General Dynamics will deliver fire control systems for the first U.S. Columbia-class training facility, installation support and pre-deployment planning for both U.S. and U.K. sites.
Design activities for the first planned refresh of the Columbia and Dreadnought fire control system are already underway.
Build A Better Future
Do you have what it takes to help us build the world's most advanced submarine systems?
We're looking for software engineers, systems engineers, technicians and others to make submarines even smarter.
