The USS Nassau (LHA-4) was a Tarawa-class amphibious assault ship constructed by Ingalls Shipbuilding in Pascagoula, Mississippi. Laid down on August 13, 1973, she was commissioned on July 28, 1979, and served until her decommissioning on March 31, 2011. Designed to support Marine Corps and Navy operations, Nassau could transport over 3,000 personnel and was equipped with extensive facilities, including 1,400 compartments, nine elevators, and two horizontal conveyors. Her engineering included two large boilers—the largest ever built for the U.S. Navy—capable of generating 400 tons of steam per hour and producing 140,000 horsepower (100 MW). The ship's electrical subsystem supplied 14 MW of power, and she had robust air conditioning rated at 1,500 tons (5.3 MW). She could ballast 12,000 tons of seawater for adjusting trim during landing craft operations from her well deck. Constructed with more than 20,000 tons of steel, 3,000 tons of aluminum, 400 miles of cable, and 80 miles of pipe, Nassau featured a 900-horsepower bow thruster for lateral maneuvering, providing a force of 20,000 pounds. Her medical facilities included a 300-bed hospital, four medical, and three dental operating rooms, supporting her role as a versatile amphibious platform capable of handling tanks, trucks, artillery, and large supplies. Throughout her service, Nassau was notable for her flexibility in operations. In 1981, she operated as an aircraft carrier for ten weeks, reinforcing her capability as a Harrier carrier, a first for the U.S. Navy. She participated in deployments to Beirut in 1984, the Middle East during Operations Desert Shield and Desert Storm, and numerous other missions supporting operations like Uphold Democracy, Deny Flight, and Kosovo-related efforts. Nassau also supported humanitarian missions, notably aiding Galveston after Hurricane Ike in 2008 and assisting Haiti following the 2010 earthquake. Her distinguished service earned her multiple awards, including the Navy Meritorious Unit Commendation and the Battle Effectiveness "E" awards. After over three decades of active service, Nassau was decommissioned in 2011 and eventually moved to the MARAD Reserve Fleet. Plans for her future included potential humanitarian use or transfer to Japan, but she was ultimately sent for disposal via recycling in April 2021.
