The LPD 17 San Antonio Class Amphibious Transport Dock Ship embarks and transports expeditionary landing forces
for a variety of U.S. combat missions. It also lands marines, equipment and supplies with the assistance of LCACs; conventional
landing craft and Expeditionary Fighting Vehicles (EFV); or Amphibious Assault Vehicles (AAV); and helicopters.
The lead ship, USS Arleigh Burke was the first U.S. Navy ship designed to incorporate shaping techniques to reduce
the ship's radar cross-section to lower its detectability and likelihood of being targeted by enemy weapons and sensors.
The LPD 17 is powered by four Fairbanks Morse 16-cylinder Colt-Pielstick PC2.5 STC two shaft diesel engines with 10,395 shp each.
As the new San Antonio Class LPDs enter service, the older Austin-class LPDs will be decommissioned.
LPD 17 is a key element of the U.S. Navy's seabase transformation and these ships will replace over 41 ships
of 4 classes of amphibious ships (LPD 4, LSD 36, LKA 113, and LST 1179), thus providing the U.S. Navy and Marine Corps
with modern, sea-based platforms that are networked, survivable, and designed to operate with 21st century weapon systems,
such as the V-22 Osprey.
The LPD-17 design includes systems configurations that reduce operating and support costs, and
other operational performance improvements. System engineering and integration efforts have developed further reductions in life-cycle costs and
integrated performance upgrades in a rapid and affordable manner.
The contract for the design and construction of USS San Antonio (LPD-17), the lead ship of the class,
was awarded in December 1996. Construction commenced in August 2000, and USS San Antonio was
delivered to the Navy in July 2005. LPDs 18-21 have also been delivered. LPDs 22, 23, 24 and 25 are all
under construction at Ingalls Shipbuilding. LPD 22, 23, 24 and 25 are all under construction at Huntington Ingalls Shipbuilding.
Advance procurement contracts have been awarded for LPD-26 and LPD-27. LPD-27, the last ship in the class, will be delivered
in November 2016.
USS New York (LPD-21) is the first of three San Antonio Class ships built in honor of the victims of the September 11 terrorist attacks.
The ship's bow stem was constructed using 7.5 tons of steel recovered from the World Trade Center site.
Furthermore, the 8th and 9th ships of the class were named Arlington and Somerset in honor of the victims of the attacks
on the Pentagon and United Flight 93. Arlington and Somerset also incorporate materials recovered from those sites.
San Antonio Class ships are equipped with two Alliant Techsystems Mk 44 Bushmaster II 30mm chain guns, two Raytheon Mk 49 RAM launching systems with 21 RIM-116 Rolling Airframe Missiles; and 10x .50 caliber (12.7mm) machine guns. For more detail, see specifications below.
The San Antonio Class Amphibious Transport Dock ship embarks, transports, and lands marines in amphibious assaults by helicopters, tilt-rotor aircraft, landing crafts, and amphibious vehicles.
