Huntington Ingalls Industries’ (HII) Ingalls Shipbuilding division has delivered the San Antonio-class amphibious transport dock ship, USS Portland (LPD 27), to the US Navy.
The navy vessel was delivered after the signing of the DD 250 document that officially transfers custody of the ship from HII to the navy.
Ingalls shipbuilding programme management vice-president Kari Wilkinson said: “For many of the shipbuilders, Supervisor of Shipbuilding representatives and members of the navy programme office, this is the 11th ship they have built and delivered together.”
The vessel has been named after the largest city in the state of Oregon, US, and was successfully launched at the HII shipyard in February this year.
To date, the company has delivered 11 San Antonio-class vessels to the US Navy.
USS Fort Lauderdale (LPD 28), the 12th ship of the same class, is currently being constructed by the company.
In June this year, Ingalls Shipbuilding secured an advance procurement contract from the US Navy for the supply of long-lead-time material and advance construction activities for LPD 29, the 13th vessel of the class.
The 684ft-long, 105ft-wide ships are the latest addition to the navy’s 21st-century amphibious assault force.
The vessels are deployed to embark and land marines, their equipment and supplies ashore by using air cushion or conventional landing craft and amphibious assault vehicles, augmented by helicopters or vertical take-off and landing aircraft such as the MV-22 Osprey.
The San Antonio-class ships are used to support a Marine Air Ground Task Force across a wide range of operations and to carry out amphibious and expeditionary missions of sea control and power projection to humanitarian assistance and disaster relief missions throughout the first half of the 21st century.
