USS Tripoli (LHA 7):


WASHINGTON (NNS) -- Secretary of the Navy Ray Mabus announced May 4, 2012 the selection of USS Tripoli as the name for the Navy's next large-deck amphibious assault ship (LHA 7).

The USS Tripoli will be the third ship to bear the name Tripoli. The name commemorates the capture of Derna in 1805 by a small force of U.S. Marines and approximately 370 soldiers from 11 other nationalities. The battle, later 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. The first USS Tripoli, an escort carrier, fought in the battle of the Atlantic during World War II. The second, an amphibious assault ship, earned nine battle stars, a Meritorious Unit Commendation, and a Navy Unit Commendation for service in Vietnam.

"USS Tripoli and the proud heritage the name represents will be an inspiration for generations of sailors and Marines who serve aboard and those who come in contact with her, reminding all the freedoms our Navy protects are as vital today as they were centuries ago," Mabus said.

Like the future USS America (LHA 6), LHA 7 has an increased aviation capacity to include 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.

The LHA 7 will use the same gas turbine propulsion plant, zonal electrical distribution and electric auxiliary systems designed and built for the USS Makin Island, replacing the maintenance intensive steam plants of earlier ships. This unique auxiliary propulsion system is designed for fuel efficiency.

The LHA 7 will provide a flexible, multi-mission platform with capabilities that span the range of military operations -- from forward deployed crisis response to forcible entry operations. The ship also will provide forward presence and power projection as an integral part of joint, interagency and multinational maritime expeditionary forces. The ship will operate for sustained periods in transit to and operations in an amphibious objective area to include: embarking, transporting, controlling, inserting, sustaining and extracting elements of a marine air-ground task force, and supporting forces by helicopters and tilt rotors supported by Joint Strike Fighters F-35B.





WASHINGTON (NNS) -- The Navy awarded a $2,381,448,356 contract to Huntington Ingalls Industries Inc. (HII) May 31, 2012 for the detail design and construction of the future USS Tripoli (LHA 7), the Navy's next large-deck amphibious assault ship.

"I'm very proud of our Navy-Industry shipbuilding team and the tremendous effort that has culminated in the award of this critical shipbuilding program," said Secretary of the Navy Ray Mabus. "This ship will ensure that the amphibious fleet remains capable of expeditionary warfare well into the 21st century."

The ship will be constructed at HII's Ingalls Operations in Pascagoula, Miss. Ship delivery is expected in fiscal year 2018.





PASCAGOULA, Miss. (NNS) -- The keel laying and authentication ceremony for the amphibious assault ship, the future USS Tripoli (LHA 7) was held at the Huntington Ingalls Industries Pascagoula shipyard June 20, 2014.

Ship Sponsor Mrs. Lynne Mabus and retired Lt. Cmdr. Steve Senk, the chief engineer of the previous Tripoli (ex-USS Tripoli, LPH 10) served as the keel authenticators. The laying of the keel traditionally marked the first step in ship construction. With today's advanced modular shipbuilding, the keel laying ceremony now recognizes the joining together of a ship's components and is a major milestone in the ship's construction. Fabrication of Tripoli started in July 2013.

"We're honored to have Mrs. Mabus with us today to confirm the ship's keel is truly and fairly laid. Mrs. Mabus is a part of this ship's history and together we can look forward to many more ship milestones," said Capt. Christopher Mercer, Amphibious Warfare Program Manager within Program Executive Office, Ships. "This keel laying ceremony marks a significant first step in bringing shape to the Navy's next amphibious assault ship."

Like the recently delivered America (LHA 6), LHA 7 incorporates key components to provide the fleet with a more aviation centric platform. The design of the future Tripoli features 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. The ship will also be the first LHA replacement ship to deliver fully ready to integrate the entire future air combat element of the Marine Corps to include the Joint Strike Fighter.

"Like America, Tripoli boasts a very credible and capable aviation centric design that replaces the Tarawa class of amphibious assault ships," said Mercer. "The design brings with it increased capabilities and will maximize the Navy's investment in future aircraft."

Along with its pioneering aviation element, LHA 7 incorporates the fuel efficient gas turbine propulsion plant, zonal electrical distribution, and electric auxiliary systems first installed on USS Makin Island (LHD 8). LHA 7 will be 844 feet in length, will have a displacement of approximately 44,971 long tons, and will be capable of operating at speeds of over 20 knots.

"We look forward to working with the professional shipbuilders of Huntington Ingalls Industries as LHA 7 takes shape here in Pascagoula," said Capt. Joe Tuite, commanding officer of Supervisor of Shipbuilding Gulf Coast.

LHA 7 is the third Navy ship to be named Tripoli. The name honors and commemorates the force of U.S. Marines and approximately 370 soldiers from 11 other nationalities who captured the city of Derna, Libya during the 1805 Battle of Derna. The battle resulted in a subsequent peace treaty and the successful conclusion of the combined operations of the First Barbary War.
