U.S. Navy new amphibious assault ship USS Tripoli LHA 7 joins the fleet


The U.S. Navy commissioned its newest America-class amphibious assault ship USS Tripoli (LHA 7) during a ceremony in Pascagoula, Mississippi on July 15 2020. Due to public health and safety restrictions on large public gatherings, the Navy commissioned the USS Tripoli administratively and the ship transitioned to normal operations.

Although the Navy canceled the traditional public commissioning ceremony due to public health and safety restrictions on large public gatherings, the Navy commissioned the USS Tripoli administratively and the ship transitioned to normal operations. Meanwhile, the Navy is looking at a future opportunity to commemorate the special event with the USS Tripoli’s sponsor, crew and commissioning committee.

LHA 7 incorporates key components to provide the fleet with a more aviation-centric platform. Tripoli’s design 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 is the first LHA replacement ship to depart the shipyard ready to integrate the entire future air combat element of the Marine Corps, to include the Joint Strike Fighter.

Along with its pioneering aviation element, 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 is 844 feet in length, has a displacement of approximately 44,000 long tons, and will be capable of operating at speeds of over 20 knots.

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, and was later memorialized in the Marines' Hymn with the line, “to the shores of Tripoli.”
