USAT Liberty was a United States Army cargo ship torpedoed by I-66 in January 1942 and beached on the island of Bali, Indonesia. She had been built as a Design 1037 ship for the United States Shipping Board in World War I and had served in the United States Navy in that war as animal transport USS Liberty (ID-3461). She was also notable as the first ship constructed at Federal Shipbuilding, Kearny, New Jersey. In 1963 a volcanic eruption moved the ship off the beach, and Liberty's wreck is now a popular dive site.

The Federal Shipbuilding and Drydock Company was a United States shipyard in New Jersey active from 1917 to 1948. It was founded during World War I to build ships for the United States Shipping Board. Unlike many shipyards, it remained active during the shipbuilding slump of the 1920s and early 1930s that followed the World War I boom years. During World War II, it built merchant ships as part of the U.S. Government's Emergency Shipbuilding program, at the same time producing more destroyers for the United States Navy than any yard other than the Bath Iron Works. Operated by a subsidiary of the United States Steel Corporation, the shipyard was located at Kearny Point where the mouth of the Hackensack River meets Newark Bay in the Port of New York and New Jersey.
