Chinese all-solid orbital launch vehicle. China's first solid propellant orbital launch vehicle was derived from the first and second stages of the DF-31 ICBM with a new solid third stage. The vehicle was named Kaituozhe-1 (Explorer-1) and was capable of putting 100 kg into polar orbits.

First flight was scheduled to occur before the end of 2002. The third stage completed its first ground test firing on February 25, 2001. The Space Solid Fuel Rocket Carrier Co., Ltd. was responsible for the development of the vehicle with the 6th Academy in Inner Mongolia responsible for the solid motors. By April 2001 overall design of the vehicle and 12 subsystems had passed critical design reviews. The company also had an ambitious long-term plan to develop seven other solid engines, three additional launch vehicles, and make up to 10 launches per year by 2007.
