Chang Zheng 11 (Long March 11)

The Chang Zheng 11 (CZ-11, or Long March 11) is a four-stage, solid-propellant, small-load launch vehicle developed by China Academy of Launch Vehicle Technology (CALT). The launch vehicle is believed to have developed from the three-stage DF-31 (NATO designation: CSS-9) intercontinental ballistic missile (ICBM), added with a solid propellant fourth-stage.

The launch vehicle made its maiden flight from a mobile pad at the Jiuquan Satellite Launch Centre on 25 September 2015, placing four small satellites into orbit. Chinese state television showed that the launch vehicle was fired from canister carried on a transporter-erector-launcher (TEL) vehicle. Development of the CZ-11 began in October 2010, initially as a commercial project funded by the China Aerospace Science and Technology Corporation (CASC). In December 2012, it became a state-funded project.

The CZ-11 is 20.8 m in length and 2.0 m in diameter, with a gross mass of 58 t and a lift-off thrust of 120 t. The launch vehicle is capable of lofting 350 kg payload to a 700 km Sun Synchronous Orbit (SSO), or 700 kg to Low Earth Orbit (LEO). The launch vehicle is fitted with a standard adopter for the launch of foreign satellites.
