First Flight II San Antonio Warship Completes Sea Trials
HII’s Ingalls Shipbuilding has completed builder’s sea trials for USS Harrisburg (LPD 30), the first San Antonio-class amphibious ship built to the Flight II standard. The multi-day trials tested propulsion, steering, ship controls, communications, mission systems and combat-system integration, and the ship returned to the Pascagoula yard after meeting its major test objectives. Flight II incorporates more than 200 changes, including the AN/SPY-6(V)2 radar and a steel mast, and is designed to support updated aircraft and landing craft while replacing aging amphibious ships. Harrisburg will undergo Navy acceptance trials before its expected delivery in late 2026; commissioning is planned for 2027.
