China’s Long March 12B Maiden Flight Sends Qianfan Satellites to Orbit Without Advance Notice
6/3/2026, 12:58:37 PM
Surprise Launch and Mission Overview
On 1 June 2026 at 4:40 a.m. EDT (0840 UTC), Long March 12B lifted off from the Dongfeng Commercial Aerospace Innovation Test Zone at Jiuquan Satellite Launch Center in the Gobi Desert. No air-space or maritime notices were issued. The rocket placed Qianfan satellites into low-Earth orbit; CASC declared the launch a success. No first-stage recovery attempt was made.
Reusable Launch Development and Qianfan Context
Long March 12B follows the December 2025 debut of Long March 12A and earlier, unsuccessful booster-recovery attempts by CASC and LandSpace. The two-stage vehicle uses nine YF-102R kerosene-LOX engines on the first stage and a vacuum-optimized YF-102RV on the second, engines also used on Space Pioneer’s Tianlong-2 and CAS Space’s Kinetica-2. The rocket supports China’s push for Falcon 9-class reusable launchers that can serve megaconstellations such as Qianfan, a Shanghai-led broadband network intended to rival SpaceX’s Starlink.
Launch Vehicle Specifications and Mission Data
Launch time: 4:40 a.m. EDT (0840 UTC) from Dongfeng test zone, Jiuquan. The 4.37-m-diameter, 72-m-long rocket can deliver ? 20 000 kg to low-Earth orbit (expended stage). A typical batch of 18 Qianfan satellites would raise the constellation to about 180. This was China’s 35th orbital launch of 2026; Long March 5 can lift up to 25 000 kg to LEO.
Official Statements from CASC
CASC announced success within an hour, calling Long March 12B a vehicle designed to cut launch costs and support China’s growing constellations, and noting its multi-orbit capability. The agency also said the launch pad is its first self-built research, test and launch facility.
International Safety Concerns
Analysts note that the absence of standard air-space and maritime alerts contravenes ICAO and IMO safety protocols, raising concerns about compliance with international norms for debris mitigation and the protection of civilian aircraft and vessels.
Conflicting Reports & Information Gaps
CASC did not disclose the exact number of Qianfan satellites carried, and the launch did not include a first-stage recovery test, leaving the reusability claim unverified for this flight.
Strategic Impact on China’s Space Ambitions
The Long March 12B offers a reusable launch option comparable to SpaceX’s Falcon 9. By delivering payloads near the capacity of the Long March 5, it can lower per-satellite launch costs, making the Qianfan network more economically viable and enhancing China’s position in the global satellite-Internet market. The vehicle also supports long-term goals such as crewed lunar landings by 2030 and large-scale space-infrastructure projects.
Upcoming Tests and Program Outlook
CASC plans further Long March 12B flights in the coming weeks, including recovery tests and trials of multi-orbit capability, while continuing Qianfan deployments. Development of reusable Long March rockets for crewed missions and lunar infrastructure proceeds.

> "Well, this was wild. The first Long March 12B rocket lifted off at 0840 UTC today from Dongfeng test zone at Jiuquan. No warning, and carrying Qianfan constellation satellites straight off the bat. Successfully reached orbit, but no recovery test today." — CASC, China Aerospace Science and Technology Corporation
