Commissioned in 1943, the USS Harder saw extensive action in the Pacific Theater. She completed ten war patrols, earning a reputation as one of the most successful submarines of World War II. Her final patrol, however, would end in tragedy.
The Final Patrol: USS Harder's Last Mission
On February 24, 1945, the USS Harder set out on her tenth war patrol. Her target was the Japanese-held island of Formosa. Despite intense enemy countermeasures, the submarine managed to sink several enemy ships. However, on March 21, the USS Harder was herself struck by a Japanese depth charge and sank with all hands.

The Discovery of the USS Harder Wreck Site
In 1998, a team of divers led by Microsoft co-founder Paul Allen discovered the wreck of the USS Harder. The site lies at a depth of approximately 240 feet (73 meters) in the Taiwan Strait. The discovery was a significant historical find, providing valuable insights into the submarine's final moments.

Today, the USS Harder wreck site is a popular destination for experienced technical divers. The site is well-preserved, with the submarine's hull largely intact. Divers can explore the exterior of the wreck, admiring the distinctive "shark mouth" bow and the four torpedo tubes that once struck fear into the hearts of enemy sailors.
Inside the wreck, divers can find personal effects left behind by the crew, including shoes, clothing, and even a copy of the New York Times dated March 18, 1945. These artifacts serve as poignant reminders of the human cost of war.
