China Builds Suspected Early Warning Radar Facility on Disputed South China Sea Island

New military installations, potentially including early warning radar, have been detected on Yagong Island in the Paracel Islands, a territory contested in the South China Sea. Latest satellite imagery, captured on August 17, indicates that construction began as early as March or April. Security experts suggest these structures on Yagong Island, a small islet northeast of Antelope Reef, could be the initial phase for supporting a larger military base being developed on Antelope Reef itself. This development comes as China is reportedly completing the first phase of construction on Antelope Reef, creating an artificial island nearly 6 kilometers long with a straight coastline over 3 kilometers long, which some experts believe could serve as a potential aircraft runway. The South China Sea is increasingly becoming a focal point for military confrontation between the United States, China, and their allies, with analysts warning of its potential significance in any future conflict involving Taiwan. Collin Koh, a security affairs expert at Singapore's S. Rajaratnam School of International Studies, noted that given Yagong Island's limited size, the facility might function as an independent observation post, but most likely as a radar station. Damien Symon, an open-source intelligence expert tracking the Paracels, also believes it could be a radar facility, though definitive conclusions are pending. China's Ministry of Defense has not yet responded to requests for comment. Official Chinese media has previously stated that construction in the area serves civilian needs such as meteorological forecasting, fishery protection, and scientific research. However, regional security analysts and military attachés interpret these island developments as efforts to bolster China's control over the northern South China Sea. The Paracel Islands have been under Chinese control since 1974, following a conflict with the former South Vietnamese navy. Vietnam, which claims sovereignty over the archipelago, has also been expanding its network of bases in the Spratly Islands in recent years. Sovereignty over the Spratly Islands and their surrounding waters is claimed in whole or in part by Taiwan, Vietnam, the Philippines, Malaysia, and Brunei.

Given the limited size of Yagong Island, the facility might be some sort of independent observation post, but most likely it's a radar station.
