The San Antonio class was designed to provide the Navy and U.S. Marine Corps with modern, sea-based platforms that are networked, survivable, and built to operate with 21st century transformational platforms, such as the MV-22 Osprey, the (since canceled) Expeditionary Fighting Vehicle (EFV), air-cushioned landing craft (LCACs), and future means by which Marines are delivered ashore.[2] The ship is more than 45 percent larger than the Austin class, displacing more than 25,000 tons at full load. It carries fewer troops, but has twice as much space for vehicles, landing craft, and aircraft.[5]
