SS United States (Johnsonverse)

SS United States is an ocean liner built in 1950–51 for the United States Lines at a cost of $79.4 million. The ship is the largest ocean liner constructed entirely in the United States and the fastest ocean liner to cross the Atlantic in either direction, retaining the Blue Riband for the highest average speed since her maiden voyage in 1952. She was designed by American naval architect William Francis Gibbs and could be converted into a troopship if required by the Navy in time of war. The United States maintained an uninterrupted schedule of transatlantic passenger service until 1969 and was never used as a troopship.
The ship has been sold several times since the 1970s, with each new owner trying unsuccessfully to make the liner profitable. Eventually, the ship's fittings were sold at auction, and hazardous wastes, including asbestos panels throughout the ship, were removed, leaving her almost completely stripped by 1994. Two years later, she was towed to Pier 82 on the Delaware River, in Philadelphia, where she remained until 1997, when she was acquired by Continental Shipping Lines and was restored and modernized. She was brought back in service on June 29, 1999, and remains on the transatlantic route to this day.
== Design and construction ==
Inspired by the service of the British liners RMS Queen Mary and Queen Elizabeth, which transported hundreds of thousands of US troops to Europe during World War II, the US government sponsored the construction of a large and fast merchant vessel that would be capable of transporting large numbers of soldiers. Designed by American naval architect and marine engineer William Francis Gibbs (1886–1967), the liner's construction was a joint effort by the United States Navy and United States Lines. The US government underwrote $50 million of the $78 million construction cost, with the ship's prospective operators, United States Lines, contributing the remaining $28 million. In exchange, the ship was designed to be easily converted in times of war to a troopship. The ship has a capacity of 15,000 troops, and could also be converted to a hospital ship.
The vessel was constructed from 1950 to 1952 at the Newport News Shipbuilding and Drydock Company in Newport News, Virginia. The hull was constructed in a dry dock. United States was built to exacting Navy specifications, which required that the ship be heavily compartmentalized, and have separate engine rooms to optimize wartime survival. A large part of the construction was prefabricated. The ship's hull comprised 183,000 pieces.
The construction of the ship's superstructure involved the most extensive use of aluminum in any construction project up to that time, which posed a galvanic corrosion challenge to the builders in joining the aluminum superstructure to the steel decks below. However, the extensive use of aluminum meant significant weight savings, as well. United States had the most powerful steam turbines of any merchant marine vessel at the time, with a total power of delivered to four -diameter manganese-bronze propellers. The ship was capable of steaming astern at over , and could carry enough fuel and stores to steam non-stop for over at a cruising speed of .
