Overview
- The Long March 12B launched on June 1, 2026 and successfully placed two Qianfan (Thousand Sails) internet satellites into low Earth orbit.
- China did not issue prior public airspace or maritime notices before the flight and outlets disagree on whether the rocket lifted from Dongfeng in Inner Mongolia or Jiuquan in the Gobi.
- CASC said the maiden flight did not attempt first-stage recovery and that booster landing demonstrations will be carried out on future missions.
- The 12B is a medium-class, partially reusable kerosene‑LOX rocket designed to lower launch costs and to support large commercial megaconstellations, making it comparable in role to SpaceX’s Falcon 9.
- Analysts say the surprise launch raises aviation-safety and transparency concerns and that faster Qianfan deployments could increase orbital traffic and pressure on China’s launch cadence and safety practices.
