SIGINT - Signals Intelligence

The Technical Department provides the PRC with a wide range of SIGINT capabilities. The Chinese maintain, by far, the most extensive SIGINT capability of any nation in the Asia/Pacific region. The Chinese operate several dozen SIGINT ground stations deployed throughout China. They monitor signals from Russia, Taiwan, Japan, South Korea, India, and Southeast Asia. Signals from U.S. military units located in the region are of significant interest to these monitoring stations. A large SIGINT facility at Hainan Island is principally concerned with monitoring U.S. naval activities in the South China Sea. The Chinese appear to be developing a spaceborne ELINT system that is mounted on their photoreconnaissance and communications satellites. There is no indication at this point that this capability presents a significant threat to U.S. forces in the region. The Chinese actively monitor international communications satellites from SATCOM intercept facilities on Hainan Island, and outside Beijing. Additionally, the Chinese have developed a series of SIGINT collection vessels that monitor U.S. military operations and exercises in the Asia/Pacific region.
