In 1989, the Soviet nuclear-powered attack submarine Komsomolets sank to the bottom of the Norwegian Sea, along with its nuclear reactor and two nuclear warheads onboard. Komsomolets was constructed with a titanium alloy exterior that allowed it to reach far greater depths than any other submarine at the time. Now, it has stayed at these depths for over 30 years, slowly leaking radioactive materials and creating ongoing concerns about radioactive contamination.
