The world's largest design, production and testing base for rockets is being built in north China's Tianjin Municipality, Liang Xiaohong, deputy head of the China Academy of Launch Vehicle Technology, told Xinhua Thursday.

The first phase of the rocket industrial base in Tianjin's Binhai New Area will be completed within the year. Rocket parts will be designed, manufactured, assembled and tested at the base, Liang said.

Twenty of the 22 plants have been completed, and some of them are ready for operation. The base is designed to meet China's growing demand in space technology research and development for the next 30 to 50 years, he added.

By integrating the industrial chain, the base will be able to produce a whole spectrum of rockets of different sizes and types for China's moon probe project, space station and other projects, he said.

China's new rockets, including Long March IV, will be designed and manufactured in the 200-hectare base, he said.
