PASACAGOULA — The amphibious transport dock Arlington (LPD 24), the eighth built at Huntington Ingalls Industries, recently returned from successful builder’s sea trials in the Gulf of Mexico.
Dock trials started last week, and the ship left HII’s Ingalls Shipbuilding division Aug. 21 for three days of at-sea testing.
More than 200 test events took place during the sea trials, including anchor handling, flight operations, ballasting and de-ballasting the well deck, and compartment air balancing.
The ship will now prepare for acceptance sea trials to demonstrate the same tests and operational success to the U.S. Navy’s Board of Inspection and Survey (INSURV).
The ship is scheduled to be delivered to the Navy this year.
The 11 ships of the LPD 17 class functionally replace more than 41 ships (the LPD 4, LSD 36, LKA 113 and LST 1179 classes of amphibious ships). Ingalls has delivered six ships in the class and has five more in various stages of construction, including LPD 24.
The LPD 17-class ships are 684 feet long and 105 feet wide and displace approximately 25,000 tons. Their principal mission is to deploy the combat and support elements of Marine Expeditionary Units and Brigades. The ships can carry up to 800 troops and have the capability of transporting and debarking air cushion (LCAC) or conventional landing crafts, augmented by helicopters or vertical take-off and landing aircraft such as the MV-22. The ships will support amphibious assault, special operations or expeditionary warfare missions through the first half of the 21st century.
