China Launches Qianfan Polar Orbit Satellite Group 15
China successfully launched the 15th group of Qianfan polar orbit satellites on July 5, 2026, deploying the payload from the Hainan Commercial Space Launch Site aboard an upgraded Long March 8A carrier rocket. The mission, which took place at 21:43 Beijing Time (13:43 UTC), marked a significant milestone for both the rocket’s performance and China’s rapidly expanding satellite internet constellation.
According to Xinhua News Agency, the Long March 8A accurately inserted the Qianfan Polar Orbit Group 15 satellites into their predetermined orbit, with the launch mission declared a complete success. The flight was the 656th mission of the Long March carrier rocket series.
Upgraded Rocket Delivers Record Performance
The Long March 8A, developed by the China Aerospace Science and Technology Corporation (CASC) First Academy, is a two-and-a-half-stage liquid propellant carrier rocket designed specifically for medium-to-low Earth orbit constellation deployment. This mission represented the first flight of the rocket following a significant performance upgrade.
Science and Technology Daily reported that during this mission, the rocket completed verification of multiple key technologies, achieving a leap in transport capacity. Both the number of satellites carried in a single launch and the total weight entering orbit set new records.
The China News Service confirmed that the upgrade involved flight profile orbital energy optimization and new engine technologies, resulting in the record-breaking payload capacity. The enhanced performance is expected to provide critical support for the high-density, large-load, batch networking launches required for China’s satellite internet ambitions.
Dual Vertical Test Stand Operations Begin
A notable operational achievement of this mission was the first use of the second vertical test stand at the Hainan Commercial Space Launch Site for final assembly and testing of the Long March 8A. This marks the establishment of a new parallel operations model for the Long March 8 series, with dual vertical test stands enabling simultaneous testing of two rockets.
China News Service reported that this new configuration increases the annual test-launch capacity to 30 launches, significantly improving efficiency over traditional models. The launch area mission cycle now stands at seven days to launch and seven days to recover — over 30% more efficient than conventional approaches.
Qianfan Constellation Accelerates Deployment
The Qianfan constellation, also known as “Thousand Sails” or the G60 Constellation, is China’s large-scale low Earth orbit (LEO) satellite internet network, built and operated by Shanghai Spacecom Satellite Technology Co., Ltd. Analogous to SpaceX’s Starlink, it is designed to provide low-latency, high-speed, high-reliability satellite broadband internet services globally, with the capability to evolve toward future 6G standards.
According to China News Service, the constellation now has over 200 satellites in orbit. The deployment follows a three-phase plan: Phase 1 aims for 648 satellites for regional network coverage, Phase 2 adds another 648 for global coverage, and Phase 3 envisions over 15,000 satellites for diversified business integration services.
The accelerated launch cadence is striking — Groups 12, 13, and 15 were all launched within a single month (June-July 2026). Group 12 launched on June 5 from Hainan, Group 13 launched on July 4 from the Taiyuan Satellite Launch Center, and now Group 15 on July 5 from Hainan.
Strategic Significance
China is rapidly building its indigenous LEO satellite internet infrastructure to compete with global constellations such as Starlink. The dual-pad, high-efficiency launch model at the Hainan Commercial Space Launch Site — China’s first commercial spaceport — is critical for sustaining the high-frequency launches needed for mega-constellation deployment.
The Hainan site, located in Wenchang, features dual vertical test stands with one pad dedicated to Long March 8 series rockets. The 83-meter-tall modular steel-concrete structure enables the 30-launch-per-year capacity that will be essential as China accelerates toward its Phase 1 target of 648 satellites.
What’s Next
With the Qianfan constellation now well past the 200-satellite mark and the Long March 8A demonstrating enhanced capabilities, China appears on track to maintain its rapid deployment tempo. The successful validation of dual-stand operations at Hainan positions the country to sustain the high launch frequency necessary for completing Phase 1 of the constellation. Industry observers will be watching for the next launch window and whether the pace of roughly one Qianfan mission per week can be maintained through the remainder of 2026.
