China's first domestically-built 100-tonne-class unmanned ship completed its first trial in open water on Tuesday in the eastern Zhejiang Province, marking a new breakthrough in the country's autonomous navigation and intelligent cabin technologies of unmanned vessels. The ship, with a length of more than 40 meters and a displacement of about 200 tonnes, has a maximum speed of more than 20 knots, and can operate normally in sea-state-code Level Ⅴ (wave height reaching 2.5 to four meters) and sail safely in sea-state code Level Ⅵ (wave height reaching four to six meters). #!language=1 Welcome to subscribe us on: Facebook: Twitter: LinkedIn:
