Best Answer

During the occupation of Japan, following WWII, US Military intelligence officers discovered several Japanese "Cyclotrons" (used during atomic research); photographs were taken (which were later published), and the devices along with all other nuclear research material were quickly dumped into the ocean. Note-Some of the photographs were taken, as the devices were being thrown into the ocean.
