The Navy’s newest and last WASP class Amphibious Assault Ship, LHD 8 USS MAKIN ISLAND, is undergoing sea testing for the first time November 2008 before an expected delivery to the US Navy in early 2009. Rather than the two steam propulsion plants used by other ships in the WASP class, LHD 8 utilizes a gas turbine/electric drive hybrid propulsion system developing a combined 70,000 horsepower that will drive the 42,800-ton ship to speeds in excess of 20 knots. The paper will discuss the testing used to prepare the LM2500+ installation on LHD 8, the first of its kind in a military application, for entry into service. This will include details on engine light-off and the testing performed both dockside and at-sea. The paper will discuss the results of the at-sea test data as it compares to the initial predictions used to provide the rationale for funding the ship’s construction project.
