US Navy Promotes Energy-Saving Programs

The USS America (LHA 6), the Navy’s newest amphibious assault ship, was commissioned during a formal ceremony at Pier 30/32 during San Francisco Fleet Week, on October 11.

Secretary of the Navy (SECNAV), the Honorable Ray Mabus, highlighted the ship’s advanced technology, including energy efficiencies that enhance the ship’s warfighting and humanitarian assistance capabilities.

“From the fuel-saving hybrid drive to a host of other systems, American technological innovation and manufacturing skill have always been powerful advantages,” said SECNAV.

In addition to its gas turbine engines, USS America is equipped with an electric auxiliary propulsion system (APS) that saves fuel at speeds under 12 knots. Because LHA ships spend the majority of their time traveling at low speeds, this hybrid system can allow the ship to stay on station longer and/or travel farther between refueling.

During the ceremony, Adm. Harry B. Harris, Commander, U.S. Pacific Fleet, stressed the importance of the Navy’s use of biofuels, fuel-saving electric auxiliary propulsion systems afloat, and solar and wind power ashore.

The Chief of Naval Operations Energy and Environmental Readiness (N45) exhibits on board the USS America (LHA 6), USS Kidd (DDG 100), and at Pier 39 highlight the Navy’s efforts to become more energy efficient and combat capable through technology and workforce training, and to explore domestically-produced sources of alternative fuel.
