Governments fear other unmarked graves are at risk of being desecrated. Hundreds more ships – mostly Japanese vessels that could contain the war graves of tens of thousands of crew killed during the war – remain on the seabed.
The rusted 70-year-old wrecks are usually sold as scrap but the ships also contain valuable metals such as copper cables and phosphor bronze propellors.
Experts said grave diggers might be looking for even more precious treasures – steel plating made before the nuclear testing era, which filled the atmosphere with radiation. These submerged ships are one of the last sources of “low background steel”, virtually radiation-free and vital for some scientific and medical equipment.
