In this episode of Shipwreck Tales, Graeme Hill is joined by John McCrystal to revisit the devastating story of the Russian submarine Kursk, which sank in the Barents Sea in August 2000 with all 118 crew lost. Together, they trace the chain of technical failure, Cold War-era secrecy and delayed rescue efforts that turned a naval exercise into one of the most haunting submarine disasters of the modern age.
