The Historic Journey of USS Lagarto (SS-371): A Legacy Beneath the Waves

The USS Lagarto (SS-371), a Balao-class submarine, holds a unique place in naval history. From its construction to its valiant service during World War II, culminating in its tragic sinking and remarkable rediscovery, the Lagarto’s story is one of heroism, sacrifice, and rediscovery. This blog post delves into the significant milestones of the USS Lagarto, highlighting its construction, tour of duty, exploits in the Gulf of Thailand, its untimely sinking, the poignant rediscovery in 2005 by Jamie McLeod, and its current status as a revered dive site.

1. Construction and Commissioning of USS Lagarto (SS-371)

Constructed at the Manitowoc Shipbuilding Company in Wisconsin, the USS Lagarto was laid down on January 12, 1944. As a Balao-class submarine, it was designed for longer range and deeper dives, boasting state-of-the-art technology for its time. The submarine was launched on May 28, 1944, and commissioned on October 14, 1944, under the command of Lieutenant Commander Frank D. Latta. The Balao-class submarines were the workhorses of the U.S. Navy during World War II, known for their robust construction and advanced sonar systems. The USS Lagarto was equipped with ten torpedo tubes, a 5-inch deck gun, and numerous anti-aircraft guns, making it a formidable adversary in naval combat.

The construction of the Lagarto was part of the United States’ rapid naval expansion during World War II, a response to the increasing threats posed by the Axis powers. Manitowoc Shipbuilding Company, located far from the coasts, was chosen for submarine construction due to its inland location, which was deemed less vulnerable to enemy attacks. The shipyard’s innovative construction techniques and skilled workforce were critical in delivering the Lagarto and other submarines on schedule.

2. The Tour of Duty: USS Lagarto's Operations

The USS Lagarto embarked on its maiden war patrol in early 1945, operating in the Pacific Theater. Its missions included aggressive patrolling, reconnaissance, and enemy engagement. The submarine’s first notable success came during its operations in the South China Sea, where it successfully sank multiple Japanese vessels, showcasing the bravery and skill of its crew. The crew of the Lagarto was well-trained and motivated, ready to undertake perilous missions to disrupt Japanese maritime operations.

During its patrols, the Lagarto played a crucial role in the broader Allied strategy to cut off Japan’s supply lines. The submarine’s ability to operate stealthily and strike without warning made it a significant threat to Japanese shipping. In addition to sinking enemy vessels, the Lagarto also gathered valuable intelligence on Japanese naval movements, which was vital for planning future Allied operations.

3. Exploits in the Gulf of Thailand

In May 1945, the USS Lagarto, in conjunction with the submarine USS Baya, was tasked with intercepting Japanese convoys in the Gulf of Thailand. The Lagarto’s mission was to disrupt enemy supply lines, a crucial component in the Allied strategy to weaken Japanese forces. During these operations, the Lagarto and Baya worked in tandem, demonstrating tactical brilliance and coordination.

The Gulf of Thailand was a strategic area for Japanese shipping, and the presence of the Lagarto and Baya posed a significant threat to enemy vessels. The submarines employed coordinated attack patterns to maximize their effectiveness, often launching torpedoes from multiple angles to overwhelm enemy defenses. The success of these operations underscored the importance of submarine warfare in the Pacific Theater and highlighted the bravery of the submariners who faced significant risks in their missions.

4.The Sinking: A Tragic End

Tragically, on May 3, 1945, the USS Lagarto met its fate. Engaging a Japanese minelayer, the Hatsutaka, the Lagarto was lost with all hands on board. The exact circumstances of its sinking remained a mystery for decades, leaving a poignant void in the annals of naval history. The loss of the Lagarto and its crew was a somber reminder of the perils faced by submariners during World War II. The submarine’s final engagement with the Hatsutaka was a testament to the bravery and determination of its crew, who continued to fight despite overwhelming odds.

The sinking of the Lagarto was part of a broader pattern of submarine losses during the war. Submariners faced extreme dangers, including depth charges, mines, and enemy attacks, often operating in isolation with limited support. The bravery and sacrifice of these sailors were crucial in achieving Allied victory, and the loss of the Lagarto was a significant blow to the U.S. Navy.

5. Rediscovery in 2005: The Efforts of Jamie McLeod

The mystery of the USS Lagarto’s final resting place was solved in 2005 by British diver Jamie McLeod. While exploring the Gulf of Thailand, McLeod discovered the wreck of the Lagarto at a depth of approximately 230 feet. This discovery provided closure to the families of the 86 brave souls who perished and offered a tangible connection to a heroic chapter of World War II history.

McLeod’s discovery was a significant achievement, made possible through meticulous research and advanced diving techniques. The wreck of the Lagarto was found largely intact, a silent testament to the bravery of its crew. The discovery of the submarine allowed for a detailed examination of its final moments, shedding light on the circumstances of its sinking and honoring the memory of those who served aboard.

The rediscovery of the Lagarto also highlighted the enduring interest in World War II history and the importance of preserving these underwater relics. The efforts of divers like McLeod ensure that the sacrifices of the past are not forgotten and provide valuable insights into the technological and tactical aspects of submarine warfare.
