China's Long March 7A rocket exploded approximately 1 minute and 20 seconds after liftoff from Wenchang Space Launch Site, likely destroying a classified military communications satellite. The failure occurred during the first stage's flight, possibly around maximum dynamic pressure, and may have been triggered by the vehicle's flight termination system. If the cause traces to the YF-100 main engine, it could have broader implications for China's space program given the engine's widespread use.
Background
China has become one of the world's most active space launch nations, conducting 50+ launches annually with a strong reliability record over the past half-decade. The Long March 7A is a key medium-lift vehicle in China's launch fleet, and the YF-100 engine powers multiple rocket variants.
