USAT Liberty

USAT Liberty is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand USAT Liberty rather than just read about it. In short: 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).

Key takeaways

  • USAT Liberty belongs to engineering; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect USAT Liberty to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of USAT Liberty from memory before moving on to harder problems.

Reference excerpt

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.

World War I Liberty was launched on 19 June 1918 by the Federal Shipbuilding Company in Kearny, New Jersey, and acquired by the United States Navy on 7 October 1918 and commissioned the same day. Assigned to the Naval Overseas Transportation Service, Liberty departed the New York Navy Yard on 24 October 1918, arriving at Brest, France, with her cargo of horses on 8 November. Over the next 6 months, Liberty made two additional cruises from New York to France discharging both animal and general cargo at French ports. Loaded with 436 tons of U.S. Army cargo and 2,072 tons of steel rails, Liberty arrived at Newport News, Virginia, on 30 April 1919 from her final cruise. She was decommissioned there on 7 May and was returned to the United States Shipping Board the same day.

Between the wars On 20 October 1929, Liberty collided with the French tug Dogue at Le Havre, Seine Maritime, France. Dogue sank with the loss of two crew members. On 23 November 1933, Liberty collided with the American cargo ship Ohioan in the Ambrose Channel. Ohioan was consequently beached near the West Bank Light.

World War II By 1939, Liberty—although owned by the United States Maritime Commission (a successor to the USSB)—was employed by the Southgate-Nelson Corporation of Norfolk, Virginia. Southgate-Nelson was the operator of several packet lines, including the American Hampton Roads Line, the Yankee Line, and the Oriole Lines, but secondary sources do not indicate for which of these services Liberty sailed. In November 1940, Liberty was one of ten ships taken up by the United States Army for defense service. At the time of the United States' entry into World War II in December 1941, USAT Liberty was in the Pacific. In January 1942, she was en route from Australia to the Philippines with a cargo of railway parts and rubber. On 11 January, Liberty was torpedoed by I-66 about 10 nautical miles (19 km) southwest of the Lombok Strait, near position 08°54′S 115°28′E. US destroyer Paul Jones and Dutch destroyer Van Ghent took the damaged ship in tow attempting to reach Celukan bawang harbour at Singaraja, the Dutch port and administrative centre for the Lesser Sunda Islands, on the north coast of Bali. However she was taking too much water and so was beached on the eastern shore of Bali at Tulamben so that the cargo and fittings could be salvaged. In 1963 the tremors associated with the eruption of Mount Agung caused the vessel to slip off the beach, and she now lies on a sand slope in 25 to 100 feet (7.6 to 30.5 m) of water, providing one of the most popular dive sites off Bali. The wreck of USAT Liberty is often misidentified as USAT Liberty Glo or identified by its former name, USS Liberty. The wreck is sometimes incorrectly referred to as a Liberty ship, through confusion of the ship's name with the class of World War II-built standard design cargo ships.

Dive site Liberty′s wreck rests about 40 metres (130 ft) from the beach in Tulamben, Bali, Indonesia. The highest point of the wreck is the stern at a depth of about 5 metres (16 ft) and the lowest point sits at about 30 metres (100 ft). Coral formations can be observed on the wreck's guns. It is also beside a species-rich zone called "Coral Garden" (depth 4-25 m).

Worked examples

Example 1 — a first encounter with USAT Liberty

Start with the simplest possible case. Write down what USAT Liberty claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to USAT Liberty before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about USAT Liberty ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of USAT Liberty

In research
USAT Liberty appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses USAT Liberty in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
USAT Liberty is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1918 ships, Buildings and structures in Bali, Design 1037 ships, so understanding it makes those chapters shorter.
In everyday life
Look for USAT Liberty outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
