The US Navy’s 12th San Antonio-class amphibious transport dock ship, LPD 28, has completed builder’s trials.

The trials included a series of in-port and at-sea demonstrations that will enable the US Navy and Huntington Ingalls Industries’ (HII) Ingalls Shipbuilding Division to evaluate the vessel’s readiness before it begins acceptance trials.

LPD 28 was christened as USS Fort Lauderdale in August this year.

US Navy Program Executive Office (PEO) Ships programme manager captain Scot Searles said: “The completion of Builder’s trials is a great first step in ensuring operational readiness of the vessel and the capabilities it will soon bring to the fleet.

“The collaboration between the navy and our industry partners ensures that we’ll have a capable and ready ship for our sailors.”

The San Antonio-class vessels are capable of conducting a variety of missions, including amphibious assault, special operations, expeditionary warfare, or disaster relief. They can also be used for transporting marines and their equipment.

The ships also feature a flight deck and hangar to operate different Marine Corps helicopters and the Osprey tilt-rotor aircraft (MV-22).

Two other vessels, the future USS Richard S. McCool (LPD 29) and the future USS Harrisburg (LPD 30), are currently under construction.

Last month, the US Navy announced that Zumwalt-class (DDG 1000) guided missile destroyer, USS Lyndon B Johnson (DDG 1002), completed builder’s trials.

DDG 1002 is the third and final ship of the Zumwalt-class vessels. These ships are designed to provide multi-mission offensive and defensive capabilities to the fleet.
