LPD-17 San Antonio Class: The USA's New Amphibious Ships

LPD-17 San Antonio Class amphibious assault support vessels are a new class of ship which is just entering service with the US Navy. Much like their predecessors, their mission is to embark, transport, land, and support elements of a US Marine Corps Landing Force. What changes are the capabilities and technologies incorporated to perform that mission, including internal technologies as well as accompanying platforms like the V-22 Osprey and Expeditionary Fighting Vehicle.

Navy sources note that the 9 scheduled ships of this class (reduced from 12) are slated to assume the functional duties of up to 41 previous ships. These include the USA's older LSD-36 USS Anchorage Class dock landing ships (all decommissioned as of 2004, LSD-36 and LSD-38 transferred to Taiwan) and its LPD-4 USS Austin Class ships (12 ships of class built and serving). The San Antonio Class ships may also replace two classes of ships currently mothballed and held in reserve status under the Amphibious Lift Enhancement Program (ALEP): the LST-1179 Newport Class tank landing ships, and LKA-113 Charleston Class amphibious cargo ships. The PMS 317 FAQ notes that the LPD-17 San Antonio Class' projected average cost once all ships are built is $1.2 billion.
