Eighty years after being sunk in combat during World War II, the final resting place of one of the Navy’s most distinguished submarines and her crew has been located.

The Naval History and Heritage Command (NHHC) last month confirmed the wreck site of the USS Harder (SS 257) at a depth of more than 3,000 feet in the South China Sea off Luzon of the Philippines. Using data collected and provided by Tim Taylor, CEO of Tiburon Subsea and the Lost 52 Project, NHHC’s Underwater Archaeology Branch identified the sunken vessel as the USS Harder.

Harder is one of 52 U.S. submarines and 3,500 submariners lost in combat during World War II and are now on “Eternal Patrol.” She was commissioned on Dec. 2, 1942, with Cmdr. Samuel D. Dealey in command; and lost at sea with 79 souls aboard on Aug. 24, 1944.

Dubbed “Hit ‘Em Harder,” the submarine had wreaked havoc among Japanese shipping and was credited with sinking 20.5 enemy ships and damaging seven more. Commanded by Medal of Honor recipient Samuel D. Dealey, her record of aggressive daring exploits became almost legendary. Harder received six battle stars and the Presidential Unit Citation for World War II service, with all six of her patrols designated successful.

Harder’s fifth war patrol in June 1944 was the submarine’s most successful. Assigned the area around the Japanese fleet anchorage at Tawi-Tawi, an island province in the Philippines, Harder depleted the critical supply of Japanese destroyers by sinking three of them and heavily damaging or destroying two others in a four-day span. The attacks disrupted the Japanese battle plans and delayed their carrier force into the Philippine Sea, which contributed to the Japanese being defeated in the ensuing battle.

During the Harder’s sixth and final war patrol, Harder had sunk two frigates off Luzon when she and another submarine, USS Hake, were attacked by a minesweeper during the early morning of August 24, 1944. Hake dived to escape the attack, but the vigorous Japanese depth charge attack sunk Harder with all hands. The Japanese ship’s crew after the attack reported “oil, wood chips, and cork floated in the vicinity.”

When the Harder failed to return to base, U.S. military officials eventually declared her lost on January 2, 1945. The entire Navy mourned the loss of the Harder crew, with Cmdr. Dealey posthumously awarded the Medal of Honor based on Harder’s fifth patrol. Dealey would be forever known in Navy lore as “a submariner’s submariner.”

Descendants of the USS Harder crew were notified about the recent discovery of the vessel. The confirmed wreck of USS Harder (SS 257) will be designated as a war grave and the final resting place of sailors that gave their life in defense of the nation.

“Harder was lost in the course of victory. We must not forget that victory has a price, as does freedom,” said NHHC Director and retired U.S. Navy Rear Admiral Samuel J. Cox in a news release. “We are grateful that Lost 52 has given us the opportunity to once again honor the valor of the crew of the ‘Hit ‘em Harder submarine that sank the most Japanese warships – in particularly audacious attacks – under her legendary skipper, Cmdr. Sam Dealey.”

U.S. Navy Commander Samuel Dealey, who commanded the Harder submarine, was posthumously awarded the Medal of Honor for his bravery and actions during World War II. He is included as part of the submarine museum’s Medal of Honor gallery.

As we celebrate Women’s History Month, we honor the courageous and trailblazing women who have shaped the U.S. Navy. From the first female enlistees to today’s top-ranking admirals, women have demonstrated resilience, leadership, and dedication to their country.

Women’s official involvement in the Navy began on May 13, 1908, with the establishment of the Navy Nurse Corps. These women provided critical medical care, setting a precedent for future generations. During World War I, the Navy faced a clerical shortage and turned to women to fill vital roles ashore.

Recognizing the need for women in service, Secretary of the Navy Josephus Daniels discovered a loophole in the U.S. Naval Reserve Act of 1916, which allowed the enlistment of qualified “persons” without specifying gender. On March 21, 1917, Loretta Perfectus Walsh made history as the first enlisted woman in the Navy, sworn in as a Chief Yeoman (F).

The latter half of the 20th century saw groundbreaking advancements for women in the Navy. In 1978, women were permitted to serve on non-combat ships, and in 1994, the restriction on female sailors serving aboard combat vessels was lifted. A pivotal milestone came in 2010 when women were granted the opportunity to serve on submarines, an area previously limited to men. 

Women have also ascended to the highest ranks of naval leadership. Admiral Michelle Howard made history in 2014 as the first woman to achieve the rank of four-star admiral. Her remarkable career continued as she became the first woman to lead Naval Forces in Europe and Africa and served as commander of Allied Joint Force Command in Naples.

Today, women serve in every facet of the Navy. Their dedication and sacrifice continue to shape the Navy’s future, ensuring that it remains a force of excellence and inclusion. As we commemorate this month, we celebrate the legacy of women in the U.S. Navy—past, present, and future.
