Huntington Ingalls Industries' (HII) Ingalls Shipbuilding division's multipurpose amphibious assault ship America (LHA 6) returned Saturday from successful builder's sea trials in the Gulf of Mexico. Ingalls' test and trials team started with dock trials Monday and then spent five days operating the ship at sea, where it conducted more than 200 test events. "It's an awesome feeling riding this ship, knowing the hard work that took place to get her ready for sea trials," said George Jones, Ingalls' LHA 6 program manager. "The LHA 6 team continued to work diligently during our time underway. The ship performed well, and our team will work to ensure LHA 6 will be prepared for her acceptance trials. We have confidence this will be a great opportunity for America to prove her mettle as she prepares to enter the U.S. Navy fleet." During builder's trials, America performed all required sea trial evolutions, including the operation of the gas turbine/electric-powered propulsion system. Other tests included anchor handling, flight operations, and combat systems' evaluations. "America, designed to take sailors and Marines into harm's way, proved her seaworthiness during builder's trials," said Richard Schenk, Ingalls' vice president of test and trials. "The test and trials team implemented a rigorous schedule of testing, including a day of dock trials, before the ship left. The Ingalls team and the ship performed very well
