Japan admitted Wednesday that its navy lost a US$5 million unmanned submarine during a survey last year, with a nine-day search of the ocean floor yielding nothing.
The Maritime Self-Defence Force was using the remote-controlled submersible in the Tsugaru strait between Japan’s main island of Honshu and its northern landmass, Hokkaido, in November, a defence ministry official.
“The vehicle was being used to survey the underwater terrain as well as water currents and temperatures,” he told AFP.
