HII’s Ingalls Shipbuilding division, Pascagoula, Miss., completed builder’s sea trials Oct. 31 for the future USS Harrisburg (LPD 30), the first Flight II amphibious transport dock in the U.S. Navy’s San Antonio class.
Over several days at sea, Ingalls crews tested the ship’s propulsion, steering, ship control, communications and mission systems. They also evaluated how the ship’s combat systems worked together.
HII said in its Nov. 3 announcement that the ship returned to the yard after meeting its major test objectives. Ingalls will prepare the ship for Navy acceptance trials and expects to deliver it by the end of 2026.
Ingalls is the sole builder of San Antonio-class ships and has delivered 13 vessels in the class, LPDs 17 through 29. Two other Flight II ships, the future USS Pittsburgh (LPD 31) and USS Philadelphia (LPD 32), are under construction at the Pascagoula yard.
Early procurement and planning are underway for three more ships in the class, the future USS Travis Manion (LPD 33), LPD 34 and LPD 35.
