Ingalls Shipbuilding Starts Fabrication on USS San Antonio-Class Ship

Ingalls Shipbuilding, a division of Huntington Ingalls Industries, announced today that it has begun construction on the U.S. Navy’s newest amphibious assault ship, John P. Murtha (LPD 26). The company was recently awarded a $1.5 billion contract to build the USS San Antonio-class ship at the Pascagoula facility.

“This is a significant milestone for Ingalls Shipbuilding and for the U.S. Navy,” said Doug Lounsberry, vice president, LPD program. “It is the first ship we’ve started with the Ingalls name, and it will become the 10^th ship in the class. Our shipbuilders are highly motivated to begin construction on this ship, and we look forward to delivering the most efficiently built LPD to date. These versatile ships provide unique capabilities to our sailors and Marines and allow them to perform several different missions in defense of our freedom.”

The start of fabrication shipbuilding milestone signifies that 100 tons of steel have been cut and fabricated. The steel is cut by a robotic plasma arc cutting machine at Ingalls’ steel fabrication complex. The next milestone for LPD 26 will be the ship’s keel laying, scheduled for the first quarter of 2012. LPD 26 is scheduled to be launched in the third quarter of 2014 and delivered to the Navy in the fourth quarter of 2015.

The 11 planned ships of the San Antonio class are a key element of the Navy’s ability to project power ashore. Collectively, these ships functionally replace more than 41 ships (the LPD 4, LSD 36, LKA 113 and LST 1179 classes of amphibious ships), providing the Navy and Marine Corps with modern, sea-based platforms that are networked and survivable and built to operate with 21st century platforms, such as the MV-22 Osprey.

Ingalls Shipbuilding has delivered the first five ships of the LPD 17 class, LPDs 17-21. San Diego (LPD 22) will undergo sea trials later this year; Anchorage is currently 82 percent complete and is expected to be delivered in the second quarter of 2012; Arlington (LPD 24) was christened on March 26, and Somerset (LPD 25) is more than 50 percent complete and will be launched in 2012.

The San Antonio-class ships are 684 feet long and 105 feet wide and displace approximately 25,000 tons. Their principal mission is to deploy the combat and support elements of Marine Expeditionary Units and Brigades. The ships can carry up to 800 troops and have the capability of transporting and debarking air cushion (LCAC) or conventional landing crafts, augmented by helicopters or vertical take-off and landing aircraft such as the MV-22. These ships will support amphibious assault, special operations or expeditionary warfare missions through the first half of the 21st century.

Huntington Ingalls Industries (HII) designs, builds and maintains nuclear and non-nuclear ships for the U.S. Navy and Coast Guard and provides after-market services for military ships around the globe. For more than a century, HII has built more ships in more ship classes than any other U.S. naval shipbuilder. Employing nearly 38,000 in Virginia, Mississippi, Louisiana and California, its primary business divisions are Newport News Shipbuilding and Ingalls Shipbuilding.
