USS Harder Expedition
a 501(c)3 Ocean Outreach Project
Veteran Ocean Explorer and Tiburon Subsea CEO Tim Taylor along with his “Lost 52 Project” team are thrilled to announce the discovery of WWII Submarine USS Harder (SS-257) and her entombed crew of 80 servicemen. This is one of the most famous submarines of World War II, awarded the Presidential Unit Citation for her successful six war patrols. Commanded by Medal of Honor recipient, Commander Samuel D. Dealey (1906–1944), the valent crew of the USS Harder sank five destroyers and rescued an embedded special forces team working behind enemy lines, receiving the Presidential Unit Citation. In addition to the Medal of Honor they were awarded four Navy Crosses.

This is a very personal and historic find for Taylor, it marks his 9th WWII Submarine discovery. He holds the distinction of being the only Ocean Explorer and Civilian to locate, document and share his historic findings with the US Navy and bring closure to families of 452 servicemen and heroes lost in battle. 

Tim Taylor is internationally recognized as an underwater robotics expert and states “working with pioneering underwater robotic technology has allowed me and my team to document each gravesite with advanced 4D modeling photogrammetry, resulting in the most comprehensive historical archeological records available today.” 

“For the USS Harder was a peer among peers, a fighter among fighters, and, above all, a submarine among submarines.” From the book “Hell and Deep Water” by Navy Vice Admiral Charles A. Lockwood 

HARDER was lost in the course of victory, and victory has a price, as does freedom - and we must not forget. We are grateful that Tim Taylor and his Lost 52 Team have given us the opportunity to once again honor the valor of the crew of “Hit ‘em HARDER,” the submarine that sank the most Japanese warships, in particularly audacious attacks under her legendary skipper, Commander Sam Dealey. Samuel J. Cox, SES RADM, USN (Ret.) Director Naval History and Heritage Command

The US Navy officially verified Lost 52 Project’s discovery of the USS Harder made at a depth of 1140 meters (3750 feet) in South China Sea.

Tim Taylor’s "Lost 52 Project" is internationally recognized by JAMSTEC (Japan Agency for Marine-Earth Science and Technology), Philippines National Museum as the first and most comprehensive offshore underwater archaeological expedition in the Pacific waters.
