"We are very pleased to deliver this ship to our Navy customer," said Mike Duthu, director of Ingalls' LPD 17 program. "With each successive LPD, we apply lessons learned that result in ship-over-ship improvements in quality, efficiency and affordability. With Somerset, the Navy is getting another very capable and adaptable amphibious warship designed and built to enable sailors and Marines to accomplish their missions." The ship successfully completed builder's trials in August and U.S. Navy acceptance trials in September. Ingalls has two more under construction at its Pascagoula, Miss., shipyard. John P. Murtha (LPD 26) is slated for completion in 2016, and Portland (LPD 27) will complete in 2017. Somerset is named to honor the courage of the passengers and crew members of United Airlines Flight 93, which crashed on Sept. 11, 2001, near Shanksville in Somerset County, Pa. LPD 25 is scheduled to be commissioned in the Navy fleet on March 1, 2014, in Philadelphia. The ship will join the two other Ingalls-built LPDs named in honor of the victims of Sept. 11, USS New York (LPD 21) and USS Arlington (LPD 24). In addition to more than 10,000 Ingalls shipbuilders, there are 650 suppliers from 38 states that support the LPD 17 program. Ingalls spends approximately $175 million a year with this vital industrial base.
