USS Harrisburg (LPD 30), the first Flight II ship of the San Antonio-class, has finished its builder’s sea trials, HII said.

The ship spent several days at sea, with the trials ending on Saturday, October 31. Tests covered propulsion and steering, along with ship control, communications, mission systems, and the integration of combat systems.

After meeting the major test objectives, the ship sailed back to the Ingalls Shipbuilding yard in Pascagoula. Acceptance trials come next, and the company expects to hand the ship to the Navy later this year.

A senior Ingalls manager for amphibious ship programs said that the trials are a key step on the way to delivering the ship to the fleet.
