The USA’s America Class NAAS: Carrier Air + Amphibious Assault
September 17/17: The US Navy’s newest America-class amphibious assault ship has been christened the USS Tripoli (LHA7). During a ceremony in Pascagoula, Miss., on Saturday, acting Undersecretary of the Navy Thomas Dee said the vessel “will be a force multiplier, and her crew will proudly serve our country for decades to come. I am grateful to the men and women of Ingalls Shipbuilding for their dedication and to the citizens of Pascagoula for their unwavering support as we continue to make our Navy stronger.” The Tripoli is an enlarged version of the America-class of amphibious assault ships. It is 844 feet long, displaces 45,000 tons and has larger hangars and storage capacity for aircraft and helicopters. Once operational, the US Marine Corps is expected to to deploy their vertical take-off and landing version of the F-35 Lightning II on the ship.
Modern U.S. Navy Amphibious Assault Ships project power and maintain presence by serving as the cornerstone of the Amphibious Readiness Group (ARG) / Expeditionary Strike Group (ESG). LHA/LHD are a key element of the Seapower 21 doctrine pillars of Sea Strike and Sea Basing, transporting, launching, and landing elements of the Marine Expeditionary Brigade (MEB) via a combination of LCAC hovercraft, amphibious transports and vehicles, helicopters, and aircraft.
Designed to project power and maintain presence, LHA-Replacement (LHA-R, aka. LH-X, and now the New Amphibious Assault Ship or NAAS) large deck amphibious assault ships were slated to replace the US Navy’s 6 LHA-1 Tarawa Class vessels. They are based on the more modern LHD Wasp Class design, with the LHD’s landing craft and well deck removed in favor of more planes and hangar space. While its LHA/LHD predecessors were amphibious assault ships with a secondary aviation element, it’s fair to describe the America Class as escort carriers with a secondary amphibious assault role.
