China successfully launched six military remote sensing satellites aboard a Long March 4B rocket on September 10, 2026, from the Jiuquan Satellite Launch Center. Designated as Yaogan 53-01 to 03 and Yaogan 56-01 to 03, the satellites are classified as government payloads with undisclosed purposes. The Yaogan series typically conducts reconnaissance and Earth observation missions for China's military and intelligence agencies, though specific technical details and operational objectives remain classified.

The Long March 4B, a medium-lift launch vehicle produced by China Aerospace Science and Technology Corporation, lifted off at 09:00 UTC carrying the six-satellite constellation into orbit. Jiuquan Satellite Launch Center in the Gobi Desert has served as one of China's primary launch facilities for government and military space missions since its establishment in 1958.

The mission achieved a successful outcome, with all six satellites reaching their designated orbital deployment. This launch exemplifies China's continued expansion of its space infrastructure and remote sensing capabilities, adding to its growing constellation of military observation satellites used for intelligence gathering and strategic reconnaissance purposes.
