San Antonio class (LPD 17) amphibious transport dock
As the San Antonio-class LPDs have entered service in recent years, Austin-class LPDs have been decommissioned. Collectively, these ships functionally replace over 41 ships providing the U.S. Navy and Marine Corps with modern, seabased platforms that are networked, survivable, and built to operate with 21st century transformational platforms, such as the MV-22 Osprey, the Expeditionary Fighting Vehicle (EFV), and future means by which Marines are delivered ashore.
