NANJING, Oct. 12 (Xinhua) -- China's two rocket-carrying ships departed Saturday from a port in east China's Jiangsu Province on a transportation mission.

The two Yuanwang ships are China's first ships made exclusively to carry rockets. With a length of 130 meters, a width of 19 meters and a height of 37 meters, the ships have a displacement of 9,000 tonnes.

Each ship is equipped with two 120-tonne cranes that can hoist large rockets. The ship is also installed with a marine environment protection system and anti-vibration equipment.

The two ships have conducted missions including the maritime transport of the Long March-7 and the Long March-5 carrier rockets. Each ship has sailed more than 40,000 nautical miles and has successfully completed more than 10 maritime transport missions.
