Josh Gates Unveils Groundbreaking WWII Discovery in Historic ‘Expedition Unknown’ Season Debut

Josh Gates has spent his career venturing off the beaten path to deliver history’s greatest mysteries directly into the living rooms of millions. From the dense, choked jungles of the Mayan settlement of El Mirador to the unforgiving, frozen slopes of Siberia’s infamous Dyatlov Pass, the Discovery Channel explorer extraordinaire has continually challenged our assumptions about a planet we believe we know well. Yet, the upcoming two-part season premiere of his global hit series Expedition Unknown is poised to deliver a breakthrough that is downright historic.
The highly anticipated two-part Season 17 premiere, titled “Hunt for the Hellships,” shifts the franchise away from ancient antiquities to document a profound, waterlogged battlefield of the Second World War. The investigative broadcast showcases Gates’s high-stakes collaboration with The Hellships Memorial Foundation to locate, analyze, and document the recently discovered underwater wreckage of the Hōfuku Maru.
Floating Concentration Camps of the 1940s
During the height of World War II, the Hōfuku Maru was one of more than 130 requisitioned merchant cargo ships and passenger liners converted by the Imperial Japanese military into specialized prison transports. These vessels earned the terrifying moniker of “Hellships” from the captive Allied soldiers trapped inside their subterranean hulls. Operating essentially as floating concentration camps, the vessels subjected prisoners of war (POWs) to brutal, inhumane conditions, starvation, and rampant disease.

Historical records indicate that over 125,000 Allied prisoners were forcibly transferred between remote labor camps aboard these converted freighters throughout the 1940s, with more than 20,000 men perishing along the grueling maritime journeys.
Aside from the horrific treatment below deck, what made the Hellships uniquely notorious was a tactical decision by Japanese commanders. The military routinely deployed these unmarked prison ships directly within standard, active naval convoys. This rendered them indistinguishable targets for Allied aircraft and submarines, who routinely attacked the fleets, entirely unaware that their own captured comrades were locked in the cargo holds below.
The Tragic Fate of the Hōfuku Maru
Such was the catastrophic fate of the Hōfuku Maru. On September 21, 1944, the heavily laden freighter was targeted by Allied forces and sunk after being struck by a devastating torpedo blast. The maritime strike instantly doomed up to 1,000 British and Dutch prisoners who remained hopelessly trapped inside the dark, rapidly flooding compartments. For more than eight decades, the faces, names, and stories of these lost soldiers were mostly forgotten by the public, and the final resting place of the vessel itself remained completely lost to time.
The historical silence was finally broken by The Hellships Memorial Foundation. Founded by U.S. Naval Officer Randy Anderson, alongside dedicated researchers Tim Beckensall and John Duresky, the organization has worked tirelessly to bring international awareness to this lesser-known reality of the Pacific Theater. Utilizing recently uncovered wartime documents, the foundation successfully pinpointed the precise, high-probability coordinates where the ill-fated vessel foundered.

Shedding Light on a Forgotten Relic
To turn these archival data points into an active archaeological recovery, the foundation partnered with Gates and an elite marine team. Equipped with cutting-edge deep-sea technology, Gates embedded with underwater imaging specialist Evan Kovacs and celebrated maritime archaeologist Dr. Calvin Mires of Marine Imaging Technologies, LLC.
The joint expedition successfully braved the hazardous underwater environments to locate the wartime relic, utilizing advanced imaging arrays to map the structural debris field. By capturing the first definitive look at the Hōfuku Maru, Expedition Unknown transitions from a standard adventure program into a vital act of historical preservation. When Season 17 officially broadcasts, viewers will witness these long-buried wartime secrets finally brought to light, honoring a generation of forgotten heroes who vanished into the deep.
