Liberty ships were a class of cargo ship built in the United States during World War II under the Emergency Shipbuilding Program. Though British in concept, the design was adopted by the United States for its simple, low-cost construction. Mass-produced on an unprecedented scale, the Liberty ship came to symbolize U.S. wartime industrial output.
North Carolina Shipbuilding Company was a shipyard in Wilmington, North Carolina, created as part of the U.S. Government's Emergency Shipbuilding Program in the early days of World War II. From 1941 through 1946, the company built 243 ships in all, beginning with the Liberty ship SS Zebulon B. Vance, and including 54 ships of the US Navy. Most of the latter were attack cargo ships (AKA), amphibious force flagships (AGC) and ammunition ships (AE). A list of all 54 Navy ships appears at the end of this article, as does a link to a detailed record of all ships built by the company.

Atlantic Reserve Fleet, New London opened in 1946 at the Naval Submarine Base New London in Groton, Connecticut on the Thames River. The New London Reserve Fleet was 3 miles north of the city New London, Connecticut. Naval Submarine Base New London opened in 1868. The freshwater port became a good site to store both submarines and ships after World War II as part of the United States Navy reserve fleets. Three submarine tender ships were given the task of mothballing the submarines. The three ships: USS Apollo, USS Anthedon, USS Proteus (AS-19) cleaned the ship and sealed the subs with preservatives. It took a few years to process the over 50 submarines in the New London Reserve fleet. Some submarines there were reactivated for Korean War. By 1965 the fleet of World War II submarine were obsolete and the fleet had been scrapped.
