PASCAGOULA, Miss. --- The Navy's newest America-class amphibious assault ship, the future USS Tripoli (LHA 7), successfully completed Builder's Trials July 19. The ship returned to the Huntington Ingalls Industries (HII)-Ingalls Shipbuilding Division's shipyard following four days underway in the Gulf of Mexico.

Builder's Trials is the Navy's first opportunity to assess the operational readiness of the ship. During the trials, the multipurpose amphibious assault ship underwent dock trials followed by more than 200 at-sea test events.

"The Navy and industry team did a commendable job this week," said Tom Rivers, amphibious warfare program manager for Program Executive Office (PEO) Ships. "America class ships bring tremendous capability to our Sailors and Marines and Tripoli will be the first large deck amphib to reach the fleet fully ready to integrate the Marine Corps air combat element to include Joint Strike Fighters."

Tripoli is the second ship of the America (LHA 6) class, built to facilitate forward presence and power projection. LHA 7 is the last Flight 0 ship planned for construction and features an enlarged hangar deck, realignment and expansion of the aviation maintenance facilities, an increase in available stowage for parts and support equipment, and increased aviation fuel capacity. LHA 8 will be the first Flight I ship, reincorporating a well deck to enhance expeditionary warfighting capabilities while maintaining the principal aviation characteristics of the Flight 0 ships.

LHA 7 incorporates gas turbine propulsion plant, zonal electrical distribution, and fuel-efficient electric auxiliary propulsion systems first installed on USS Makin Island (LHD 8). LHA 7 will be 844 feet in length, will have a displacement of approximately 45,000 long tons and will be capable of operating at speeds of over 20 knots.

HII's Pascagoula shipyard is also currently in production on Bougainville (LHA 8), the guided missile destroyers Delbert D. Black (DDG 119), Lenah H. Sutcliffe Higbee (DDG 123), Jack H. Lucas (DDG 125), and amphibious transport dock ships, Fort Lauderdale (LPD 28) and Richard M. McCool Jr. (LPD 29).

As one of the Defense Department's largest acquisition organizations, PEO Ships is responsible for executing the development and procurement of all destroyers, amphibious ships, special mission and support ships, boats and craft.

PASCAGOULA, Miss. --- Huntington Ingalls Industries announced today the successful completion of builder’s trials on the amphibious assault ship Tripoli (LHA 7). The second ship in the America class spent four days at sea in the Gulf of Mexico, testing the ship’s main propulsion, combat and other systems before returning to HII’s Ingalls Shipbuilding division.

“Congratulations to the Navy and Ingalls team for a solid LHA 7 builder’s trials,” said Ingalls Shipbuilding President Brian Cuccias. “We have an excellent leadership team, and they will now be focusing on getting the ship ready for acceptance trials and delivery to the Navy. The flight deck modifications to support the F-35 Joint Strike Fighter aircraft provide an increased aviation capacity and demonstrate how an experienced team can evolve the platform to meet the current threats across the globe.”

Ingalls is currently the sole builder of large-deck amphibious warships for the U.S. Navy. The shipyard delivered its first amphibious assault ship, the Iwo Jima-class USS Tripoli (LPH 10), in 1966. Ingalls has since built five Tarawa-class ships, eight Wasp-class ships and the first in a new class of ships, USS America (LHA 6). The third ship in the America class, Bougainville (LHA 8), is currently under construction at the shipyard and will be the 16th large-deck amphibious ship built at Ingalls.

“We work with an amazing team of individuals who are committed to making each LHA better than the last,” said George S. Jones, Ingalls’ vice president of operations. “From our shipbuilders, test and trials crew, and our Navy Supervisor of Shipbuilding partners, there is never a doubt that when these warships go to sea for trials they go out with the confidence and dedication of our team behind them. We build these state-of-the-art warships for the men and women of the U.S. Navy and Marine Corps, and that is a responsibility our shipbuilders take great pride in, and that pride really showed during this trial.”

Like the lead ship in the class, Tripoli is designed for survivability with increased aviation capacity, including an enlarged hangar deck, realignment and expansion of the aviation maintenance facilities, a significant increase in available stowage for parts and support equipment, and increased aviation fuel capacity. Similar to its predecessors, the ship will be able to operate as the flagship for an expeditionary strike group.

Tripoli will be the third ship to bear the name that commemorates the capture of Derna in 1805 by a small force of Marines and approximately 370 soldiers from 11 other nations. The battle, memorialized in the Marines’ Hymn with the line “to the shores of Tripoli,” brought about a successful conclusion to the combined operations of the First Barbary War.


Huntington Ingalls Industries is America’s largest military shipbuilding company and a provider of professional services to partners in government and industry. For more than a century, HII’s Newport News and Ingalls shipbuilding divisions in Virginia and Mississippi have built more ships in more ship classes than any other U.S. naval shipbuilder. Headquartered in Newport News, Virginia, HII employs more than 40,000 people operating both domestically and internationally.
