NANJING, July 12 (Xinhua) -- China's new generation of space tracking ship, the Yuanwang-7, which will perform maritime tracking of manned spaceflight Shenzhou-11 and other space missions later this year, was formally launched on Tuesday after a 60-day trial period.
The vessel, designed by China, marks a new high for China's space tracking technology, said a statement.
The construction of the ship started on Oct. 10, 2014 in Jiangnan Shipyard (Group) Co., Ltd. The 220 meter-long, 40 meter-high ship has a displacement of 25,000 tons. Capable of resisting strong typhoons, the ship can carry supplies to last for 100 days, the statement said.
China boasts a fleet of seven Yuanwang space tracking ships, which have carried out some 70 expeditions and traveled more than 1.5 million nautical miles in the Pacific, Atlantic and Indian oceans.
Shenzhou-11 will carry two astronauts to dock with Tiangong-2, China's second orbiting space lab to be launched in the fall. The docking is expected to allow two astronauts to live in space for up to 30 days.
The Yuanwang-1 and Yuanwang-2 ships, China's first-generation space tracking vessels, were launched in 1979, making China the fourth country to master space tracking technology after the United States, Russia and France.
