Chinese Long March 7A Rocket Explodes 85 Seconds After Liftoff Destroying Military Satellite

BLUFShared first-stage architecture between the Long March 7 and 7A means Monday's failure during initial engine burn directly threatens China's Tiangong station resupply schedule.

A Chinese Long March 7A rocket exploded about 85 seconds after liftoff from Wenchang Space Launch Site in Hainan on Monday night, destroying the vehicle and its ChinaSat-4B communications satellite over the South China Sea 12. CASC, the state-owned launch operator, had issued no statement by the time of initial reporting 1, but state news agency Xinhua confirmed the failure roughly three hours later, attributing it to an in-flight anomaly that remains under investigation 2. South China Morning Post reported that space observers suggested the anomaly may have triggered the rocket's flight termination system, based on infrared tracking imagery appearing to show it breaking apart near its upper section 2. The explosion occurred before the three-minute mark when the 7A's boosters and core stage normally separate 1.

Analysis
Chinese launch operators face a review of the entire Long March 7 family, since the standard variant carrying Tiangong resupply missions shares the 7A's first stage and core and cannot be ruled out as sharing Monday's fault until investigators isolate the anomaly. This is the type's second total loss since its 2020 debut, but unlike that failure, which struck after stage separation, Monday's anomaly hit during the initial engine burn common to both variants. Sourcing draws broad, high-reliability convergence: an Aviation Week primary account corroborated within hours by SpaceNews and Space.com, with South China Morning Post's next-day follow-up adding official confirmation rather than echoing the initial wire. Space observers favor a deliberately triggered flight termination system responding to a lesser onboard fault over an uncontained structural or propulsion failure as the likelier cause of the vehicle's destruction.
