Canadian-built technology was recently used to locate and record images of a lost World War II submarine.
In early August 2015, a team of experts and Japanese TV crew members discovered a missing World War II icon. Off the coast of Nagasaki, the 120 meter long submarine "I-402" was located using a SEAMOR Remotely Operated Vehicle (ROV).
TOYO Corporation, SEAMOR's Japanese dealer, used their built-in-Nanaimo (British Columbia) 300 F 2/4 ROV system with high definition video to seek out and then document the sunken vessel. Found at 190 meters below the surface, the bright LEDs on the SEAMOR ROV were able to illuminate key features of this submarine. A pair of rails along the front of the ship were key identifiers as the I-402 as they provided a track upon which the three on-deck Seiran seaplane dive bombers were able to be launched (the I-400 and I-401, the only two other vessels of this kind, also had this capability).The crane/hoist system to retrieve the planes and the exhaust stack were also spotted and help confirm the identity of this ship.
