The NS Savannah is a historically significant nuclear-powered merchant ship, notable as the first of its kind to be built for peacetime use. Launched on July 21, 1959, she measures approximately 596.5 feet (181.81 meters) in length with a beam of 78 feet (24 meters). Her design was innovative, featuring a sleek, futuristic appearance with a raked, teardrop-shaped superstructure decorated with stylized atom graphics, reflecting her atomic propulsion system. The ship's superstructure is positioned aft to accommodate the centrally located nuclear reactor, which is housed within a cylindrical containment vessel measuring 14 feet in diameter and 50 feet in length, designed to civilian standards emphasizing safety and reliability. Constructed by New York Shipbuilding Corporation in Camden, New Jersey, Savannah's design was developed by George G. Sharp, Inc., with her reactor built by Babcock & Wilcox. She boasts a displacement of around 21,800 short tons (19,800 tonnes) and features nine watertight compartments, including seven cargo holds, a reactor compartment, and machinery spaces. Her cargo capacity was modest—about 8,500 short tons—compared to conventional ships, but she was equipped with modern cargo handling gear and passenger amenities, including a lounge, swimming pool, and dining facilities, making her resemble a luxury vessel. Her nuclear reactor, a 74 MW pressurized-water reactor, was a focal point of her design, utilizing low-enriched uranium and emphasizing safety with extensive shielding—composed of lead, polyethylene, and concrete—and specialized containment measures. The reactor was operational from her commissioning in 1962 until de-fueling in 1975, with the fuel and radioactive components later disposed of in Utah, and residual radioactivity declining over the decades. Savannah's service included demonstration voyages, international ports, and a notable 1969 visit to New York City, where she became a symbol of atomic peace initiatives. She operated actively until 1971, traveling over 450,000 nautical miles and carrying nearly 1.4 million visitors during her public exhibitions. After deactivation, she was moored in Baltimore and later became a museum ship at Patriots Point, although she was eventually moved for decommissioning preparations. Designated a National Historic Landmark in 1991, Savannah remains an emblem of technological innovation and the Atoms for Peace program, with ongoing efforts for preservation and decommissioning, expected to conclude by 2031.
