BEIJING, May 1 (Xinhua) -- China plans to launch a Long March-11 carrier rocket at sea this year, which is expected to lower the cost of entering space.

The rocket has been named "CZ-11 WEY" under an agreement between the China Academy of Launch Vehicle Technology, China Space Foundation and a Chinese automobile producer.

The seaborne launch technology will help China provide launch services for countries participating in the Belt and Road Initiative.

The Long March-11, with a length of 20.8 meters and a takeoff weight of about 57.6 tonnes, is the only rocket using solid propellants among China's new generation carrier rockets. It has a relatively simple structure and can be launched in a short time.

The rocket can carry a payload of up to 350 kg to a sun-synchronous orbit at an altitude of 700 km and 700 kg to a low-Earth orbit at 200 km. It is mainly used to carry small satellites, and can take multiple satellites into orbit at the same time.
