Long March 6A | TJSW-27A & B
Provider: China Aerospace Science and Technology Corporation
Vehicle: Long March 6A
Launch Date:
Launch Site: Launch Complex 9A
Target Orbit: N/A
Orbital Compute Tier: Minimal
The Long March 6A provides China with a domestically sourced medium‑lift launch capability that underpins rapid deployment of large satellite constellations such as Qianfan and SatNet, supporting national broadband and remote‑sensing strategies. By offering a versatile launch configuration (solid strap‑on boosters plus dual kerosene/LOX engines), the vehicle enhances China’s competitive position against foreign providers like Antares and Soyuz‑2. The continued success of this launcher reinforces China’s geopolitical influence in low‑Earth orbit commercial and strategic services.
Orbital Compute Analysis
No information has been released indicating that the payload carries onboard AI/ML, edge‑compute, or advanced data‑relay capabilities; the mission’s compute relevance is therefore unknown.
Vehicle Analysis
The Long March 6A is a two‑stage, medium‑lift launch vehicle with four solid strap‑on boosters, a first stage powered by two YF‑100 kerolox engines, and a second stage using a YF‑115 engine; it can lift at least 6 500 kg to a 500 km sun‑synchronous orbit. It is manufactured by the Shanghai Academy of Spaceflight Technology (SAST) under the China Aerospace Science and Technology Corporation (CASC). Since its inaugural flight in March 2022, the vehicle has completed 25 launches with a 100 % success record.
Strategic Context
Long March 6A serves as a key launch option for Chinese commercial broadband constellations (e.g., Qianfan and SatNet) and for domestic Earth‑observation missions, helping China reduce reliance on foreign launch services. Its competitive payload capacity places it alongside other medium‑lift vehicles such as Antares and Soyuz‑2, expanding market options for regional satellite operators. Successful operation of this launch will sustain the growth trajectory of China’s LEO constellations and associated revenue streams.
