Description:
The LPD 17 San Antonio class ships will be a highly reliable, warfare capable amphibious transport docks designed to replaced current LPD 4, LSD 36, LST 1139 and LKA 113 ships. They incorporate state-of-the-art self-defense capabilities, C4ISR, and reduced radar cross section signatures, as well as reduced operational costs and capability to incorporate technological advances. In addition, San Antonio class ships also incorporate the latest quality of life standards for the embarked Marines and Sailors.
The LPD 17 ships will be able to accommodate EFV, formerly AAAV, vehicles, LCAC or LCU landing crafts, and MV-22 tilt-rotor aircraft. They will perform as amphibious transports, amphibious cargo ships and landing docks. A flight deck and a well deck have been provided to these ships to support landing craft. Overall, LPD 17 class ships are operated with a 360-man crew comprising officers and enlisted personnel. Its landing force may include 800 Marines and their equipment such as fighting vehicles, landing crafts and rotary-wing aircraft.
San Antonio design features the latest in command, control, communications, computers, intelligence, surveillance and reconnaissance capabilities (C4ISR). As an expeditionary warship will be the most survivable amphibious vessel ever put to sea. Survival is based on a combination of sensors and weapons for self-defense and reduced radar cross section (RCS) signature. Stealthy was achieved streamlining its topside design and introducing advanced technologies.
The advanced enclosed mast/sensor system (AEM/S) replaces conventional masts, protecting radar and communications antennae from weather and reducing the ship's vulnerability to detection by hostile radar. As of early 2006, the AEM/S is the largest composite material structure ever installed on a US Navy steel ship.
Originally, the US Navy plans were to procure up to 12 LPD 17 San Antonio ships. As of early 2006, the US Navy plans call for procurement of 9 ships.
LPD 17 sailed from Northrop Grumman Corporation's Pascagoula shipyard for the first time on April 29, 2005, for her initial at-sea testing in the Gulf of Mexico. The LPD 17 named USS San Antonio was expected to achieve initial operational capability and commissioning in February 2007. Finally, USS San Antonio was commissioned by the US Navy on January 14, 2006, at Naval Station Ingleside, Texas.
On 1st June, 2006, Northrop-Grumman announced that the US Navy awarded a $2.49 billion contract for the construction and further development of LPD 17 San Antonio-class ships. The contract called for construction of two ships, LPD 22 and LPD 23, and the purchase of long-lead material and equipment in support of LPD 24.
The US Navy christened the USS Green Bay (LPD 20) Landing Platform Dock ship on July 15, 2006 at Northrop Grumman Ship Systems � Avondale Operations, Avondale, Louisiana. USS New York (LPD 21) has the unique characteristic that the bow stem was formed using steel from the World Trade Center (WTC) destroyed on 11S.
On 6 November 2006 the US Navy awarded Northrop-Grumman Ship Systems a $1.45 billion contract for the construction of LPD 24 and long lead materiel procurement for LPD 25 amphibious assault ship.
