The U.S. Coast Guard is executing various infrastructure modernization projects across its bases to support new major cutters.

In September 2026, a $173.7 million contract was awarded for Phase 1B of the Base Seattle modernization. This project focuses on developing shore infrastructure, including a new pier, dredging, and utility upgrades, to accommodate future Polar Security Cutters for Arctic and Pacific missions. While the first three phases are expected to conclude by 2030, reports indicate potential delays for the first cutter until at least 2033.

By October 2026, the Coast Guard completed a $132.5 million rebuild of Pier November at Base Charleston in South Carolina. Finished ahead of schedule, the new pier is designed to accommodate up to five major cutters. This project, partially funded by the One Big Beautiful Bill Act, is part of a larger $440 million modernization effort at Base Charleston.
