The first satellite in China's Yunhai-1 ('Cloud Sea') series, launched November 2016 into a 485-mile sun-synchronous orbit. Chinese state media describes Yunhai-1 satellites as providing atmospheric, marine, and space environment detection alongside disaster prevention services — but Western analysts assess the series as military meteorological satellites, given the program's PLA sponsorship and its close resemblance to defense weather satellite designs elsewhere. Weather data has always had dual-use military value: an accurate forecast determines whether a missile launch window, an amphibious landing, or a reconnaissance flight proceeds.
