❓ What is the complete history of the USAT Liberty Wreck from construction to present?

The vessel’s 104-year journey from New Jersey shipyard to Bali seabed represents one of maritime history’s most unusual wreck trajectories. Understanding this narrative enhances guide training, marketing content, and guest experience value.

Construction and Early Service (1918-1941) : Built by Federal Shipbuilding Company in Kearny, New Jersey, and launched June 19, 1918, the 4,809-ton vessel measured 411.5 feet length with 55-foot beam . Commissioned as USS Liberty (ID 3461) on October 7, 1918, it transported horses and cargo to France during World War I, completing three Atlantic crossings before decommissioning in May 1919 .

Interwar Period: Returned to merchant service, the ship collided with French tug Dogue at Le Havre in 1929, sinking the tug with two crew lost. Another collision with Ohioan in 1933 forced beaching near Ambrose Channel .

World War II Service: Requisitioned by U.S. Army in November 1940, USAT Liberty transported war materials in the Pacific. On January 11, 1942, en route from Australia to the Philippines with railway parts and rubber cargo, Japanese submarine I-166 torpedoed the vessel approximately 10 miles southwest of Lombok Strait .

Beaching and Volcanic Displacement: USS Paul Jones and HNLMS Van Ghent attempted to tow the damaged ship to Singaraja port, but flooding necessitated intentional beaching at Tulamben . For 21 years, the wreck sat partially exposed on the beach. The 1963 eruption of Mount Gunung Agung generated tremors that slid the vessel into its current submerged position, breaking it into sections during descent .
