How a Submarine Sank a Fishing Boat – The Antares Disaster (Real Events)

In 1990, the Scottish fishing trawler Antares vanished beneath the calm waters of the Firth of Clyde. What appeared to be a sudden and tragic accident soon revealed a chilling truth — the vessel had been pulled under by a Royal Navy submarine during a midnight training exercise. This documentary retraces the final voyage of Antares, the moment of collision, and the investigation that followed — uncovering how a routine naval drill became one of the most haunting maritime disasters in British waters. Through real accounts and historical records, Deep SOS explores what really happened that night — when the sea turned silent, and four men were lost to the deep.
