The Long March 6A was developed by the Shanghai Academy of Spaceflight Technology and uses a two-and-a-half-stage design.
Each of the four solid rocket boosters on the Long March 6A produces 124 tons of thrust from an unspecified solid propellant, resulting in a combined booster thrust of 492 tons.
Launch teams supporting Long March 6A missions have enhanced weather protection measures to address frequent thunderstorms at Taiyuan during this part of the year.
The Long March 6A payload capacity is 4,500 kilograms to a 700-kilometer sun-synchronous orbit.
The fairing on the September 7, 2025 Long March 6A mission was split into three segments with the uppermost half segment deploying during ascent and the remaining segments detached during the payload deployment sequence.
Launch teams supporting Long March 6A missions have improved documentation and processes for personnel handovers.
A previous Long March 6A launched from Launch Complex 9A at Taiyuan on August 17, 2025 at 22:15 China Standard Time (14:15 Coordinated Universal Time) headed for a near-polar orbit with another group of internet satellites.
The Long March 6A is the first new-generation Chinese launch vehicle to utilize a combination of solid and liquid propellants and was developed by the Shanghai Academy of Spaceflight Technology.
The September 7, 2025 Long March 6A liftoff time corresponded to 16:34 Coordinated Universal Time on September 6, 2025.
The Long March 6A conducted its seventh flight of 2025 on the Yaogan-40 Group-03 mission and had last flown twenty days earlier.
All Long March 6A launches to date have launched from the Taiyuan Satellite Launch Center in northern Shanxi province.
The Long March 6A first stage is powered by two YF-100 engines generating a combined thrust of approximately 244 tons using rocket-grade kerosene and liquid oxygen.
The Long March 6A second stage is powered by a single YF-115 engine producing 18 tons of thrust using rocket-grade kerosene and liquid oxygen.
A Long March 6A lifted off from Launch Complex 9A at the Taiyuan Satellite Launch Center at 00:34 China Standard Time on September 7, 2025 (16:34 UTC on September 6, 2025) heading for a polar orbit.
The Long March 6A used a special payload fairing and adapter to deploy the three Yaogan-40 satellites, similar to Arianespace’s Système de Lancement Double Ariane.
A previous Long March 6A launch from Taiyuan lifted off from Launch Complex 9A at 22:15 China Standard Time (14:15 UTC) on August 17, 2025 headed for a near-polar orbit carrying another group of internet satellites.
Three satellites atop the Long March 6A on September 7, 2025 were part of Yaogan-40 Group-03 developed by the China Academy of Space Technology.
The September 7, 2025 Long March 6A mission was the vehicle’s seventh flight of 2025 and it had last flown twenty days earlier.
The Long March 6A for the Yaogan-40 Group-03 mission used a special payload fairing and adapter similar to Arianespace’s Système de Lancement Double Ariane.
The payload on the Long March 6A launch consisted of three satellites forming Yaogan-40 Group-03 developed by the China Academy of Space Technology.
