The eighth Nimitz-class supercarrier of the United States Navy, named after the 33rd President of the United States, Harry S Truman. HST's callsign is Lone Warrior and is currently homeported at Naval Station Norfolk, Virginia.

Harry S Truman was launched on 14 September 1996 by Newport News Shipbuilding, Newport News, Virginia, and commissioned on 18 July 1998 with Captain Thomas Otterbein in command. President Bill Clinton was the keynote speaker, and other notable attendees and speakers included Missouri Representative Ike Skelton, Missouri Governor Mel Carnahan, Secretary of defence William Cohen and Secretary of the Navy John H. Dalton.

USS Harry S Truman was initially the flagship of Carrier Group Two and, beginning 1 October 2004, of Carrier Strike Group Ten.

Beginning in 2001, the Harry S Truman Carrier Battle Group participated in Operation Joint Endeavor, Operation Deny Flight, Operation Southern Watch, Operation Enduring Freedom – Afghanistan, Operation Iraqi Freedom, Summer Pulse '04, and NATO Operation Medshark/Majestic Eagle '04.

Harry Truman (also known as HST within the Navy) is 1,092 ft (333 m) long, 257 ft (78 m) wide and is as high as a twenty-four-story building, at 244 feet (74 m). The super carrier can accommodate approximately 80 aircraft and has a flight deck 4.5 acres (1.8 ha) in size, using four elevators that are 3,880 ft² (360 m²) each to move planes between the flight deck and the hangar bay. With a combat load, HST displaces almost 97,000 tonnes and can accommodate 6,250 crewmembers. Her four distilling units can make 400,000 U.S. gallons (1,500 m³) of potable water a day; her food service divisions serve 18,000 meals per day. There are over 2,500 compartments on board requiring 2,520 tonnes (2.1 MW) of air conditioning capacity (enough to cool over 2,000 homes). The warship uses two Mark II stockless anchors that came from USS Forrestal and weigh 30 tonnes each, with each link of the anchor chain weighing 360 pounds (160 kg). She is currently equipped with three 20 mm Phalanx CIWS mounts and two Sea Sparrow SAM launchers. The ship cost over $4.5 billion in 2007 dollars to manufacture.

Two Westinghouse A4W nuclear reactors are used for propulsion (the ship is capable of steaming more than three million miles before refueling) turning 4 five-bladed screws that weigh 66,220 pounds (30 t) each driving the ship at speeds over 30 knots (56 km/h).

While underway, the ship has its own daily newspaper, the "Give 'em Hell Herald", and its own weekly television newscast, "The Lookout". In addition, the ship's Morale, Welfare & Recreation (MWR) division collaborates with the public affairs office (PAO) to telecast bingo contests for the crew that award as much as $1,000 and several prizes.
