US and Japan join forces for China spy sub

12 August 2014

The Japanese and American militaries are to collaborate on an unmanned submarine to monitor China's undersea fleet. The Defense Ministry and the US Navy are to design an unarmed, 10-metre-long vessel capable of carrying out surveillance activities for up to 30 days, reported Japanese paper the Yomiuri Shimbun in August.

Initial research will concern high-performance, hydrogen-based fuel cells capable of operating quietly for extended period without using air.

The ministry plans to spend about ¥2.6 billion on the project over the next four years and intends to select a contractor for a fuel cell prototype by the end of 2014.
