What happened
China is pushing ahead with a full-scale runway on Antelope Reef in the Paracel Islands, according to satellite images reviewed by Reuters and analysts who expect paving and a first landing by mid-2027.
What the images show: Photos taken Sept. 25 by commercial provider Vantor show grading, piles of gravel and concrete, compaction cranes, and a gravel barge at a newly built wharf, Reuters reported. Open-source tracker Damien Symon earlier flagged dredging at the reef.
Analyst view: Ben Lewis of PLATracker said that if Fiery Cross Reef is the guide, the runway could be paved in the first half of 2027 with a first landing by mid-2027 or earlier. He said he has not yet seen excavation for ammunition and fuel storage that a base of this scale would need.
Why it matters
A second major offshore runway after Fiery Cross would be China’s most significant South China Sea expansion in a decade, Reuters’ analysts said — at a time of sharper U.S.–China competition over Taiwan.
What’s next
Watch further commercial satellite passes for paving and support infrastructure.
More context
China’s position: China’s Defence Ministry did not immediately respond to Reuters. Beijing has not acknowledged a new military base; state media has said Antelope will serve civilian needs such as weather forecasting and maritime research.
Strategic stakes: Analysts say a completed Antelope base would extend Chinese naval and air reach in the northern South China Sea and help cover approaches to Hainan Island, home to nuclear-armed ballistic-missile submarines. The Paracels are also claimed by Vietnam and Taiwan; both ministries had no immediate comment to Reuters. China has occupied the Paracels since a 1974 clash with then–South Vietnam.
Uncertainty: Imagery cannot prove final military use. Timelines are estimates. Storage and hangar buildout is not yet confirmed.
