The Kuaizhou-11

  • Kuaizhou, meaning “fast ship” in Chinese, was operated by the commercial launch firm Expace and was originally scheduled for 2018 after being developed three years earlier.
  • Also known as KZ-11, it had a lift-off mass of 70.8 tonnes, and was designed to launch low-Earth and Sun-synchronous orbit satellites.
  • It was carrying two satellites — the first being a remote sensing satellite that would provide data to clients on a commercial basis for forecasting and managing geological disasters.
  • It would also provide the information required for natural resource exploration. The second was part of a series of satellites for low-Earth orbit navigation.
  • Both satellites were built by Changguang Satellite Co. Ltd., a commercial entity born out of the state-owned firms.
