According to CCTV News, on March 29,Longyin 9, the world's largest and China's first 10,000-ton ocean communications cable laying ship, was launched in Jiujiang, Jiangxi Province.

The ship adopts full electric propulsion and dynamic positioning control system. The ship is classified into China Classification Society, and the research and development, design and manufacture of the whole ship realize complete autonomous control.

Longyin 9 is 155 meters long and 23.2 meters wide. It has a endurance of 60 days, a maximum speed of 15 knots and a one-time cable carrying capacity of 10,000 tons.It can complete the laying of submarine cable across the Pacific Ocean from China in one go.
