Discovery Channel’s new season of Expedition Unknown premieres with an episode focused on the Hōfuku Maru. The two-part season premiere, “Hunt for the Hellships,” will air on Wednesday, June 24, 2026 at 9pm ET/PT.

“The story of the Hellships is a chapter in the history of WWII that demands to be brought to light,” said host and explorer Josh Gates. “The research and dives that led to this groundbreaking discovery can hopefully offer closure to the families of more than a thousand servicemen who made the ultimate sacrifice. It’s a privilege to work alongside the Hellships Memorial Foundation to honor their memories; they are lost no more.”

Gates and The Hellships Memorial Foundation worked together to locate the Hōfuku Maru, which sank in September 1944 with more than 1,000+ Allied prisoners on board. The season premiere also features the US Military’s DPAA (Defense POW/MIA Accounting Agency), a group working to recover POW remains from the Ōryoku Maru, which sank in Subic Bay, Philippines.

Discovery released this description of the two-part season premiere:

“POWs called these floating concentration camps ‘Hellships,’ yet their shocking legacy remains one of the lesser-reported atrocities of the Second World War. More than 130 requisitioned cargo ships and passenger liners were repurposed by Imperial Japan to transport prisoners between forced labor sites across South Asia. Notorious for their brutally inhumane conditions, of the more than 125,000 Allied prisoners transported in ‘Hellships,’ an estimated 20,000 died onboard. And, because the Japanese would hide the ships within their military convoys, the vessels became targets for the Allies, who were unaware of their true purpose.

On September 21, 1944, the freighter Hōfuku Maru was sunk by an Allied torpedo, breaking in half and going under in less than three minutes, with up to 1,000 British and Dutch prisoners still in her holds. Tragically, the identity and location of the sunken Hellship was lost in the fog of war, and the story of the Hōfuku Maru largely forgotten…until now.

More than 80 years later, the Hellships Memorial Foundation – founded by retired U.S. Naval Officer Randy Anderson and later joined by researchers Tim Beckensall and John Duresky – uncovered long-buried documents in both the American and Japanese military archives that place the sinking of the Hōfuku Maru more than 30 miles away from where it was assumed to have been lost.

Explorer Josh Gates partnered with The Hellships Memorial Foundation, as well as underwater imaging specialist Evan Kovacs and maritime archaeologist Dr. Calvin Mires of Marine Imaging Technologies, LLC, on a heroic mission to locate the Hōfuku Maru. The team used sonar to confirm an uncharted wreck in their search zone, then conducted a series of deepwater dives to identify the wreck, culminating in the sobering discovery of human remains among the debris.

The size of the vessel along with the position of the ship’s masts, cargo holds, and detailed photogrammetry of the wreckage was compared against blueprints of the Hōfuku Maru, which matched to a tee. The wreck is also violently split into two pieces, matching both American and Japanese descriptions of her fate by torpedo hit.”
