Kuaizhou-11 Launches from Jiuquan
Summary: On June 17, 2026 at 03：40 UTC, a Kuaizhou-11 rocket lifted off from Jiuquan, China, with HYDROPAC 1725/2026 issuing a corresponding reentry notice.
According to a NASASpaceflight Forum post dated June 17, 2026, a Kuaizhou-11 launch vehicle lifted off from the Jiuquan Satellite Launch Center at 11:40 Beijing time (03:40 UTC). Forum trackers independently confirmed the ascent trajectory and the staging events. Kuaizhou-11 is developed by the China Aerospace Science and Industry Corporation (CASIC), with the Fourth Academy acting as system integrator and primary manufacturer. The vehicle is a four-stage solid-fueled rocket with a payload capacity of roughly 1.5 tonnes to low Earth orbit and about 1 tonne to a 700 km Sun-synchronous orbit; it flies with a 2.2-meter fairing and is intended primarily for small-satellite rapid-response and replenishment launches.
Within hours of liftoff, the U.S. Navy HYDROPAC service issued notice 1725/2026, defining a maritime and aerial hazard area for an upcoming reentry. HYDROPAC notices typically correspond to controlled or uncontrolled reentries of upper stages or final rocket bodies, and the timing of the warning aligns with the flight profile of a Kuaizhou-11 mission.
As of writing, neither CASIC nor the Jiuquan Satellite Launch Center has published an official statement disclosing the payload identity, customer, or final orbital parameters. The forum thread likewise does not provide a definitive answer, so the only externally confirmable details remain the launch time, launch site, and the associated reentry warning.
