China has completed the first phase of construction on a 1,500-acre artificial island at Antelope Reef in the South China Sea, satellite imagery reveals. The transformation from a submerged reef a year ago underscores Beijing’s accelerating militarization of disputed waters.
The new island, located 160 nautical miles south of Hainan, features a 2,000-foot quay capable of berthing warships and the foundations for a 10,000-foot military runway. Three construction zones are active around a central lagoon, with concrete plants supporting ongoing work. A China Coast Guard vessel was recently spotted docked at the quay, signaling operational use.
Strategically positioned south of Sanya Port and Yulin Naval Base, the outpost extends China’s radar coverage and anti-access/area denial capabilities. Analysts note it will enable persistent aerial patrols and intelligence, surveillance, and reconnaissance operations, though China claims the site will serve civilian purposes.
The project marks the latest in a decades-long campaign to assert control over the South China Sea, despite international legal challenges.
