Yaogan Military Reconnaissance Satellite Constellation
Geography: Asia Pacific · East Asia · China
The Yaogan (遥感) series is China's primary military intelligence, surveillance, and reconnaissance (ISR) satellite constellation, comprising over 178 active spacecraft as of 2025. The constellation includes multiple satellite classes: Jianbing-5 (electro-optical), Jianbing-6 (ELINT/signals intelligence), Jianbing-7 (SAR radar imaging), Jianbing-8 (multi-spectral), and Jianbing-9/10 (technology demonstration). New launches continue at a pace of 10-20 per year, with Yaogan-45 launched in September 2025.
The Yaogan constellation provides the PLA with persistent, all-weather surveillance capability globally. SAR satellites (Jianbing-7 class) operate with side-looking radar enabling imaging through clouds and at night. Multi-satellite formations enable rapid revisit times over areas of interest including the Taiwan Strait, South China Sea, and the Indian Ocean. This capability is critical for China's anti-access/area-denial (A2/AD) strategy, providing targeting data for anti-ship ballistic missiles.
At 178+ satellites, Yaogan represents arguably the most significant military space buildup since the Cold War. The constellation's scale — approaching the size of the US military satellite fleet — transforms China from a regional to a global ISR power. Combined with BeiDou navigation and Tianlian data relay satellites, China has built a complete sovereign space-based C4ISR architecture independent of any foreign systems.
