USAT Liberty a Ship Full of History

The USAT Liberty Shipwreck, located in Tulamben, Bali, is a renowned dive site with a century-long history tied to global wars and natural events. Its transformation from a 1918 cargo ship to a dive attraction involves World War I, World War II, and a significant volcanic eruption. Below is a detailed account of why this 120-meter wreck rests 40 meters from Tulamben’s shore, a key destination for shipwreck diving.

In 1918, World War I prompted rapid shipbuilding in the United States. Federal Shipbuilding Company in Kearny, New Jersey, constructed the SS Liberty Glo, launching it on June 19 for the Emergency Fleet Corporation. The vessel, 125 meters long and 17 meters wide, had a 7,000-ton capacity for cargo such as horses, food, and munitions. A steam engine, fueled by coal or oil, powered a single propeller, operated by a crew of approximately 40. It served the Naval Overseas Transportation Service, delivering supplies until the war ended in November 1918.

Post-war, the Liberty Glo entered commercial service under operators like American Hampton Roads Line and Yankee Line, transporting grains and machinery across the Atlantic. It encountered incidents: in 1929, near Brest, France, it collided with a small boat in fog, sinking it and causing two fatalities. In 1933, it struck the SS Ohioan off New York, grounding the other ship. Its durable hull sustained it, and by 1939, the US Maritime Commission oversaw its commercial routes.

World War II altered its purpose. In November 1940, the US Army requisitioned it as USAT Liberty to carry supplies including rubber, railway parts, canned goods, and bullets to Pacific allies. Painted gray for camouflage, it sailed from San Francisco. In early 1942, it departed Australia for the Philippines, loaded with rubber and railway components, navigating the Dutch East Indies, now Indonesia.

On January 11, 1942, a critical event occurred. While passing through the Lombok Strait between Bali and Lombok, Japanese submarine I-166 fired a torpedo at approximately 4:30 AM. The torpedo hit the starboard engine room, causing severe flooding. No crew members were lost, but the ship was heavily damaged. Allied destroyers, USS Paul Jones and Dutch Hr.Ms. Van Ghent, attempted to tow it to Singaraja, a northern Bali port, to salvage its cargo. Excessive water intake forced the crew to beach it at Tulamben on January 14, 1942, with the bow on sand and stern in shallow water.

For 21 years, the Liberty remained on Tulamben’s black-pebble beach, becoming a local landmark. Villagers salvaged metal for tools and homes, removing guns, anchor chains, and fittings. Rust spread, paint peeled, and exposure to Bali’s sun weathered it, integrating it into the coastal landscape, often visited by fishermen and children.

In 1963, Mount Agung, Bali’s 3,142 meters volcano, erupted after decades of dormancy. Seismic activity began in February, escalating to a March 17 eruption that killed over 1,500 people and devastated villages. Lava flows and tremors altered Tulamben’s coastline. Between March and May, the Liberty slid into the sea, fracturing into sections. It settled on its starboard side, parallel to the shore, at depths ranging from 3 to 30 meters, establishing it as a dive site.

Coral growth accelerated post-1963, facilitated by the hull’s rusted state, stripped of marine paint during its beach years. By the 1980s, divers observed extensive hard and soft corals, with fish like snappers and eels inhabiting the structure. Today, over 400 species, including barracudas and nudibranchs, populate the wreck, cementing its status as a premier Bali dive site. Its historical significance attracts divers globally.

Underwater Features of the Liberty Wreck

The USAT Liberty Shipwreck, located 40 meters from Tulamben’s shore, spans 120 meters and depths of 3 to 30 meters, offering multiple features for divers. Below are the primary areas to explore during a Tulamben diving trip, a highlight among Bali dive sites.

  • Stern (4-18 meters): Shallow section, accessible for beginners and snorkelers. Contains a gun covered in hard corals like table and branching types, with schools of small fish such as damselfish and anthias present.
  • Bow (13-29 meters): Deeper area for experienced divers. Includes an anchor chain encrusted with coral growth, frequently visited by barracudas and occasional jackfish schools.
  • Engine Room (13-20 meters): Houses machinery remnants, including boiler fragments, hosting moray eels and octopuses. A dive light is required for clear visibility of interior spaces.
  • Cargo Holds (8-20 meters): Open compartments with soft corals and schools of snappers and sweetlips, previously used for storing wartime cargo like rubber and munitions.
  • Break (12-22 meters): Midsection where the ship split, creating passages with fusiliers, sergeant majors, and other fish moving through coral-covered gaps.
  • Artillery Section (20-25 meters): Deeper area with additional guns, encrusted in plate and soft corals, attracting groupers and rare reef shark sightings.
  • Bank (8-12 meters): Flat coral platform hosting macro life, ghost pipefish, and juvenile batfish, suitable for detailed observation.
  • Surrounding Reef (3-14 meters): Adjacent natural corals with clownfish, anemones, and small wrasses, connecting the wreck to Tulamben’s broader reef system.

The wreck’s steel framework supports extensive coral coverage, including hard corals like brain and mushroom types, soft corals, yellow and red sponges, and sea fans. Additional structures include scattered deck plates near the stern, rusted railings along the break, and partial hull panels in the cargo holds, all colonized by marine growth. These features make the Liberty a central destination for shipwreck diving, with varied depths and points of interest for all diver levels.

Day Dives on the Liberty Wreck

Fusiliers and snappers school in groups of dozens around cargo holds and the break, feeding on plankton. Parrotfish consume corals in the stern and bank, butterflyfish swim in pairs near sea fans, and gobies hide in crevices throughout the wreck. Moray eels, including green and spotted varieties, occupy the engine room and artillery section. Turtles, mainly hawksbill, are seen near the bow, grazing on sponges.

Macro species include seahorses, frogfish, and nudibranchs in colors like blue and orange, located on the bank and surrounding reef. Barracudas patrol the bow in small groups, while trevally schools move through deeper areas like the artillery section. Sweetlips congregate in cargo holds, often in clusters of 10 or more. Angelfish and triggerfish swim near the stern, and juvenile batfish hover around the bank. These species are active during daylight, providing varied sightings.

Night Dives on the Tulamben wreck

Bioluminescent plankton is visible with water movement across the wreck. Spanish dancers, a red sea slug species, appear in cargo holds and near the break. Flashlight fish, small and glowing, swim in the engine room and darker passages. Shrimps and crabs, including cleaner and hermit varieties, emerge from corals at the stern and bank.

Parrotfish rest in mucus cocoons in the cargo holds, lionfish hunt around the bank with spread fins, and basket stars extend across corals to feed, mainly near the stern. Moray eels remain active, hunting in the artillery section. Pufferfish and boxfish settle near the surrounding reef, and nocturnal cardinalfish school under ledges in the break. Night dives reveal species less common during the day.

How The Dive Begin on the Liberty Wreck

Divers begin on Tulamben’s black-pebble beach, where local staff assist with gear setup and transport tanks to the water’s edge. Entry involves walking over pebbles into shallow water, followed by a 40-meter swim to reach the wreck. Beginners focus on the stern at 3-12 meters, where corals and small fish are abundant.

Advanced divers explore the bow or artillery section at 25-30 meters for larger species. A thin wetsuit or rash guard is adequate for warmth. Guides provide pre-dive briefings, covering safety protocols and wreck layout, and lead groups to specific features like the engine room, cargo holds, or bank. Dives typically last 45-60 minutes, depending on air consumption and depth. Surface intervals occur on the beach, with shade and water available from nearby vendors, restaurant or cold box from your dive center.
