GDEB Wins Contract to Continue Columbia-Class Submarine Development


The U.S Navy has awarded General Dynamics Electric Boat a $126.1 million contract modification to continue development of the Common Missile Compartment for the U.S. Navy’s Columbia-class submarine and the Royal Navy’s Successor-class ballistic-missile submarine. Electric Boat is a wholly owned subsidiary of General Dynamics.

The contract modification includes funding for procurement of long-lead time material for missile tubes which will be integrated into both the Navy’s new SSBN and the Royal Navy’s Dreadnought-class strategic missile submarine.

Initially awarded in September 2017, the fourteen-year, $5.1 billion contract calls for Electric Boat to perform design and development work for the Navy’s next-generation ballistic-missile submarine, which is scheduled to begin construction in fall of 2020. The potential value of the overall contract is $6.1 billion.

Ballistic missile submarines are critical, stabilizing and efficient elements of the U.S. nuclear deterrence and assurance policy, carrying the majority of deployed U.S. nuclear warheads. Columbia-class SSBNs incorporate advanced technology and will provide the most survivable leg of the Nation's strategic triad.

According to the US Navy, the mission of the Ohio Replacement will be Sea Based Strategic Deterrence:
Replacing Ohio SSBN class, rehosting TRIDENT II D5 (LE) missile system, providing the most survivable leg of the Nation's strategic triad.
