Summary: In the Fall of 2003, the aged Russian nuclear-powered submarine K-159 sank in the Barents Sea, resulting in the deaths of nine sailors and leaving a potential environmental hazard due to its onboard nuclear reactor.
-Originally commissioned in 1963 and decommissioned in 1989 without being defueled, the K-159 sank while being towed for scrapping, highlighting its deteriorated condition.
-The wreckage, lying 781 feet underwater, poses a significant threat due to its corroded hull and the presence of spent nuclear fuel.
