Portland completes builder’s trials
The US Navy’s upcoming San Antonio class amphibious transport dock, the future USS Portland (LPD 27), has successfully completed builder’s trials following four days of operations in the Gulf of Mexico, Huntington Ingalls Industries announced on 3 July.
The builder’s trials included a series of tests and at-sea demonstrations to prepare the ship for final inspection by the US Navy’s Board of Inspection and Survey. Tests included anchor-handling, ballast/de-ballast of the ship’s well deck, detect-to-engage, full power ahead and astern and steering demonstrations.
The ship will now undergo acceptance trials in August before it is delivered to the US Navy.
The 684ft San Antonio class ships are used to embark land marines, their equipment and supplies ashore via 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.
