General Dynamics Electric Boat (GDEB) received a contract modification by the US Navy for the Columbia-class ballistic missile submarine program (SSBN).

The total value of the new modification contract is approximately $ 313.9 million.

The modification is in the Integrated Product and Process Development Agreement (IPPD), previously awarded by the US Marine Corps Command.

As part of the latest agreement, GDEB will support the development and expansion of the industrial base for the construction of Colombia-class submarines.

The company will also support efforts to acquire, manufacture and supply strategic weapons maintenance kits for the United Kingdom.

In addition, GDEB will continue to work with its subcontractors and suppliers to increase production capacity to meet the increased requirements of the SSBN Class Columbia program.

GDEB President Kevin Graney said: “Ballistic missile submarines are a critical, surviving part of our country’s nuclear arsenal, and Colombia is a top priority for acquiring the Navy.

“We are grateful for the strong trust and support that the Navy and Congress have in Electric Boat as we continue to work, we started 15 years ago to deliver Colombia and the next 60 years of restraint for our nation.

The 560-foot-long Columbia-class submarines will have the ship’s fuel core, which will provide sufficient power for the entire life of the submarine. This will increase the period of deployment of the submarine.

GDEB has a contract with the US Navy to build Columbia-class submarines to replace Ohio-class ballistic submarines.

In 2020, the company received a contract for the construction of the first and second Columbia-class SSBNs.

The company is expected to hand over the first submarine to the US Navy in 2027.
