The award to General Dynamics Advanced Informational Systems is worth $95.9 million. The contract has a maximum value of $225 million if all options are exercised.
The systems covered under the contract -- on U.S. and British Trident II submarines -- are the SSBN fire-control system, the SSGN attack weapon-control system, the U.S. SSBN-replacement and the British SSBN-successor common missile compartment.
"We have a 50-year partnership with the Navy supporting strategic weapons systems and this award is a validation of our team's performance in supporting the modernization and enhancement of the Trident program," said Lou Von Thaer, president of General Dynamics Advanced Information Systems.
"Looking forward, the introduction of the common missile compartment will be instrumental for the next generation of SSBN platforms for the U.S. and U.K. navies. Deploying a common compartment across different platforms will decrease cost and introduce more flexibility for meeting today's mission requirements and those of the next generation of sailors."
The U.S. Navy in 2002 started replacing aging components of the Trident II missile and General Dynamics will continue to oversee elements of that program, known as D5 Life Extension.
