Flying since 2013, Kuaizhou 1 and 1A consist of three solid-fueled rocket stages, with a liquid-fueled fourth stage as part of the satellite system. Kuaizhou 11, which flew an unsuccessful maiden flight in July 2020 (and successful second flight in 2022), is a larger model able to launch a payload into low Earth orbit. Heavy-lift models KZ-21 and KZ-31 are in development.
