The LPD-17 San Antonio Class Amphibious Transport Dock Ship

About the LPD 17:





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 on July 20, 2005 and commissioned on January 14, 2006. LPDs 18-25 have also been delivered. USS Somerset (LPD 25) was delivered on October 18, 2013 and commisioned March 1, 2014. LPD 26 PCU John P. Murtha and LPD 27 PCU Portland are under construction at Ingalls Shipbuilding. Advance procurement contracts have been awarded for both ships. The future USS Portand (LPD 27), the final ship in the class, will be delivered in June 2017.

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.



Armament/Ship Self-Defense:

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.



Price/Unit Cost:

The unit cost of an LPD 17 San Antonio Class ship is $2.03 billion (end cost in FY 2012).



Total Cost - Life of Program (LoP):

The total procurement cost of the LHA Replacement program is $19.01 billion (official DoD estimate) + $0.12 billion in research and development (RDT&E) funds, which means the total estimated program cost is $19.13 billion (numbers are aggregated annual funds spent over the life of the program and no price/inflation adjustment was made).



Mission/Role:

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.
