Wenchang Space Launch Site, People's Republic of China

The Wenchang Space Launch Site is a rocket launch site located in Wenchang on the island of Hainan, in China. Formally a suborbital test center, it currently serves as China's southernmost spaceport. The site was selected for its low latitude, 19° north of the equator, allowing for larger payloads to be launched. It is capable of launching the Long March 5, the heaviest Chinese rocket. Unlike launch facilities on the mainland, Wenchang uses its seaport for deliveries.

Frequently asked questions

Long March 5 Specs

Long March 5 is a Chinese heavy lift launch system developed by China Academy of Launch Vehicle Technology (CALT). CZ-5 is the first Chinese vehicle designed from the ground up to focus on non-hypergolic liquid rocket propellants. Currently, two CZ-5 vehicle configurations are planned, with maximum payload capacities of ~25,000 kilograms (55,000 lb) to LEO and ~14,000 kilograms (31,000 lb) to GTO. The Long March 5 roughly matches the capabilities of American EELV heavy-class vehicles such as the Delta IV Heavy.
