The ships of the LPD 17 class are a key element of the Navy’s seabase transformation. Collectively, these ships functionally replace over 41 ships (LPD 4, LSD 36, LKA 113, and LST 1179 classes of amphibious ships) providing the 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.
