China Advances Runway Construction on Antelope Reef in the South China Sea

Satellite imagery captured on September 25 shows grading, gravel piles, concrete and compaction cranes operating at Antelope Reef (Lingyang Reef, ???) in the Paracel Islands. The images, provided by commercial provider Vantor, also reveal a fully loaded gravel barge delivering material to a newly built wharf. Analysts assess the work is part of a runway project that could be paved in the first half of 2027 with an inaugural aircraft landing by mid-2027.

The Paracel archipelago has been under Chinese control since a brief 1974 battle that expelled South Vietnamese forces, a claim contested by Vietnam and Taiwan. China’s recent activities have focused on expanding offshore military infrastructure, most notably the 3 km runway built on Yongshu Reef (Fiery Cross, ???) in the Spratly Islands in 2015. The Antelope Reef project is viewed as the most significant expansion in the region in a decade, intended to extend the operational reach of Chinese naval vessels and aircraft and to safeguard approaches to Hainan Island, where China stations its nuclear-armed ballistic-missile submarines.

• September 25 – Vantor satellite images show active grading, gravel loading and crane operations at Antelope Reef.

Japan Times

• Early 2024 – Open-source tracker Damien Symon first reported dredging activity at the reef.

Taipei Times

• Mid-2027 (projected) – Expected completion of runway paving and first aircraft landing.

Taipei Times

• Runway length projected to match the 3 km Yongshu Reef runway constructed in 2015.

Taipei Times

• Multiple compaction cranes observed, indicating large-scale earth-moving and reclamation efforts.

A completed runway would enable a broader spectrum of Chinese warships and combat aircraft to operate farther from the mainland, reinforcing Beijing’s strategic posture in a waterway contested by the United States and its allies. The base would also enhance protection of the Hainan Island region, a critical hub for China’s nuclear-armed submarine fleet.

Taipei Times

• The Chinese Ministry of National Defense has not responded to requests for comment.

Taipei Times

• Chinese state media assert that Antelope Reef will serve civilian purposes such as weather forecasting and maritime and scientific research.

Taipei Times

• Vietnam’s Foreign Ministry and Taiwan’s Defence and Foreign Ministries declined to comment.

Reuters identified new installations on nearby Yagong Island (???) in late August, describing a three-pronged structure whose function remains undetermined. Analysts have not reached a consensus on whether the Yagong Island works support the Antelope runway, serve a separate logistical role, or have a civilian purpose.

• “If Fiery Cross is the guide, I’d expect the runway paved in the first half of 2027 and a first landing by mid-2027, possibly earlier,” — Ben Lewis

China has recently confirmed the establishment of a joint military support facility in Laos, indicating a broader strategy to deepen its presence in Southeast Asia. No specific future milestones for the Antelope Reef runway have been announced beyond the mid-2027 projection.
