China Completes 1,500-Acre Antelope Reef Island as 10,000-Foot Runway and 2,200-Foot Quay Take Shape

Summary
Satellite imagery dated Aug. 11 shows China has finished the first phase of a nearly 1,500-acre artificial island at Antelope Reef after about 10 months of nonstop dredging.
The new outpost already includes a deep-water port, a 680-meter quay and the early grading for a 10,000-foot military-grade runway, with a coast guard vessel recently seen docked there.
Antelope Reef lay mostly submerged a year ago; China reclaimed the site by moving more than 1 million tons of sand, creating a 3.7-mile island ringed by seawalls and internal roads.
The reef sits about 160 nautical miles south of Hainan and 200 nautical miles east of Da Nang, giving Beijing another platform to extend surveillance, air operations and maritime presence in the disputed South China Sea.
China says the project is for civilian and commercial use, but the buildout mirrors earlier island bases that Beijing later militarized across contested waters also claimed by Vietnam and Taiwan.

Overview
Between 2025 and 2026, China rapidly transformed Antelope Reef into a massive artificial island with a military-grade runway and deep-water harbor, using covert tactics like disabling ship transponders to avoid detection. This new outpost, now capable of supporting heavy military aircraft and warships, pushes Chinese radar and strike capabilities closer to Vietnam and strengthens Beijing’s preparations for a Taiwan conflict. The construction triggered strong protests from Vietnam and condemnation from the United States and its allies, leading to expanded regional defense partnerships and a destabilizing arms buildup. Meanwhile, severe ecological damage and the failure of international law to restrain China have intensified regional tensions.
