Is a New Chinese Runway Taking Flight at Antelope Reef?

Eight months after China began dredging at Antelope Reef in the Paracel Islands, the first signs of major infrastructure at the new artificial island have emerged. Satellite images from August show digging that appears likely to be the start of a new runway:

No concrete or other paving material has been laid down yet and work has only begun on a portion of the likely airstrip, but several factors serve as evidence for this conclusion.    

The area being shaped is consistent with the 180-foot width of China’s existing South China Sea runways at Fiery Cross, Subi, and Mischief Reef in the Spratlys and Woody Island in the Paracels. The work is taking place along the reef’s northwestern edge, the only straightaway available at Antelope to accommodate a 10,000-feet runway like those at China’s other outposts. The area being worked on currently extends 4,300 feet but is clearly a work-in-progress.

Other earth-moving in the north seems to anticipate the extension of the runway up the full length of this edge. Digging is underway for the foundation of at least one structure adjacent to the expected runway which matches the dimensions (200×200 feet) of the larger hangars located at China’s other South China Sea airstrips.

Though this preparatory work is the first sign of major infrastructure construction on Antelope, the reef itself has come a long way since AMTI’s last check-in. The landfill and dredging work at Antelope appears to be complete, with no dredgers in sight in recent imagery, and the finalized landmass now measures 1,458 acres.

The only area of the reef in active use remains the eastern tip to the south of the channel leading into the lagoon. This was the only area under active construction during dredging and is likely serving as the reef’s administrative headquarters. Several new buildings have gone up here in recent months, and the installation of green areas and paved parking lots are turning this from a frontier outpost into an administrative center typical of China’s other islands.

The only other construction of note has been the operation of two concrete plants which emerged in late spring along the northwest and southern edges of the lagoon. These are likely temporary facilities that will play a key role in providing materials for other infrastructure before eventually being moved or replaced by more permanent structures.
