Kuaizhou

China (PR)

History:

The rocket series is based on CASIC's Anti-satellite weapon (ASAT) and BMD mid-course interceptor rockets, in particular the DF-21 Intermediate-range ballistic missile (IRBM) (another Chinese rocket that was based on DF-21 was the Kaituozhe-1). Development on the KZ launch vehicles started in 2009. The Kuaizhou launch vehicles were to provide an integrated launch vehicle system with the rapid ability to replace Chinese satellites that might be damaged or destroyed in an act of aggression in orbit. The vehicle uses mobile launch platform. The launch vehicle is operated by the PLA Rocket Force.
The maiden flight of Kuaizhou 1 launch vehicle, orbiting the Kuaizhou 1 natural disaster monitoring satellite, occurred on 25 September 2013, launched from Jiuquan Satellite Launch Center.
The first commercial launch inaugurated the Kuaizhou 1A version on 9 January 2017, from Jiuquan Satellite Launch Center. It placed three small satellites into a polar orbit.
The maiden launch of Kuaizhou 11 was on 10 July 2020. The launch was a failure, and the rocket was initially declared retired in April 2022, but later that year it was revealed that a second launch was planned for December.The successful launch of Kuaizhou 11 on 7 December 2022 marked the rocket's return to service.
