BAE Systems Begins Overhaul of USS Green Bay to Extend Service Life.
According to a PR published by BAE Systems on January 16, 2025, the US Navy has awarded BAE Systems a $212 million contract for the modernization of the USS Green Bay (LPD 20), a San Antonio-class amphibious transport dock. The project falls under a Docking Selected Restricted Availability (DSRA) contract, which includes extensive maintenance, repair, and upgrades designed to extend the ship's service life and operational capabilities. Work is set to begin in February 2025 at BAE Systems’ San Diego shipyard, with completion expected by October 2026.

The USS Green Bay is part of the San Antonio class. These vessels form a critical component of the Navy’s amphibious readiness groups and expeditionary strike groups, supporting a wide range of operations. The San Antonio class is serving in combat roles, humanitarian missions, and disaster relief efforts.
Each ship in the San Antonio class is designed with a well deck capable of launching and recovering amphibious vehicles, landing craft, and other maritime platforms. Additionally, a flight deck supports rotary-wing aircraft and tilt-rotor MV-22 Ospreys, enabling air mobility and amphibious assault operations. Advanced command-and-control systems allow these vessels to act as operational hubs for complex missions.
The DSRA contract for USS Green Bay includes several critical upgrades. The ship will be dry-docked for maintenance of its underwater hull, addressing wear and ensuring optimal performance. Repairs to the ballast tank system will improve stability, crucial for operations in varying maritime environments. The well deck, used for amphibious vehicle deployment, will undergo preservation to maintain its operational readiness. Additionally, living quarters will be refurbished to enhance habitability for the crew of sailors and Marines.
The San Antonio class, designed with lifecycle extensions in mind, is built to incorporate incremental upgrades, allowing ships like USS Green Bay to stay technologically advanced and mission-capable for decades.
The San Antonio class represents a significant leap forward in amphibious warfare design. Compared to its predecessors, these ships incorporate reduced radar cross-sections for enhanced survivability and are equipped with advanced communication and control systems. They can support various Marine Corps operations, including mechanized and air assault missions.
Each ship features significant capacity for carrying troops, vehicles, and equipment. The USS Green Bay, for example, can house 800 Marines in addition to its standard crew. Its deck space is capable of supporting 12 Expeditionary Fighting Vehicles (EFVs) or comparable amphibious platforms, while its vehicle stowage area and cargo holds provide flexibility for mission-specific loads. Amphibious transport dock ships like USS Green Bay are pivotal in regions such as the Indo-Pacific.
