The fixed-price, incentive-fee contract to build the Coast Guard's sixth National Security Cutter, the USCGC Munro, is worth $487 million.
"Our Coast Guard customer continues to be extremely pleased with the performance of the NSC, and this contract proves that," said Jim French, Ingalls' NSC program manager. "Our shipbuilders continue to execute well on this contract, and the design/build plan is at a mature stage.
"We currently have two more ships under construction and expect to start NSC 6 in October."
NSCs were designed to replace the 378-foot Hamilton class high-endurance cutters.
National Security Cutters are 418 feet long, 54 feet in the beam and displace 4,500 tons with a full load. They have a maximum speed of 28 knots and a range of 12,000 miles.
Ingalls said a long-lead materials contract for the Munro was awarded last year and all equipment for the cutter has been ordered.
Ingalls builds, integrates and tests the NSC hull, mechanical and electrical systems. Lockheed Martin provides the cutter's command, control, communications, computers, intelligence, surveillance and reconnaissance capabilities.
