New satellite imagery shows China has accelerated construction on a small island in the disputed Paracel archipelago, adding to what analysts describe as a rapidly expanding military footprint in the South China Sea.
The photos, taken August 17 by commercial imaging firm Vantor, reveal several new buildings on Yagong Island, about 8.5 miles northeast of the larger Antelope Reef. The structures first appeared in satellite images from March and April, but the latest pictures show substantial progress, according to Vantor.
“Several structures on Yagong Reef resemble other military radar/early warning facilities seen elsewhere in the South China Sea and are likely associated with the ultimate military functions of nearby Antelope Reef,” the company said in its analysis.
Antelope Reef transformation
Antelope Reef, a small atoll claimed by China, Vietnam, and Taiwan, has been the focus of a massive dredging and landfill operation since October 2025. The effort has expanded the reef to roughly four miles long and nearly 1,500 acres — large enough to accommodate a 9,000-foot runway, according to Vantor’s assessment.
Analysts believe the expanded reef could host surveillance installations, missile batteries, electronic warfare facilities, and an underground storage complex. Its lagoon is now large enough to become the biggest harbor in the area, potentially turning what was once one of China’s smallest outposts into a major military base.
Yagong Island itself is a much smaller feature, but its new buildings could serve as a platform for radar and electronic systems to support operations at Antelope Reef, Vantor said.
Beijing dismisses concerns
The Chinese Defense Ministry did not respond to questions from reporters about Yagong Island. Chinese state media has maintained that all development in the Paracels is for civilian purposes, including weather forecasting and scientific research.
China’s state-run Global Times on Wednesday dismissed foreign media interest in Antelope Reef — which Beijing calls Lingyang Jiao — as hype and fearmongering. The paper characterized the buildings on Yagong Island as a “civilian facility” but provided no evidence, details, or attribution for that claim.
Instead, the paper devoted extensive space to complaining about foreign observers who accuse Beijing of militarizing the South China Sea.
“Some Western media outlets view China’s activities through the lens of a geopolitical and military rivalry, and their positions and views appear to have become fixed. Even before island construction and facility deployment have been completed, they have already reached preconceived conclusions about so-called militarization,” Ding Duo, research director at the National Institute for South China Sea Studies, told the Global Times.
In a striking contradiction, Ding then suggested the sites might indeed be military in nature — saying it was “entirely reasonable for China to deploy necessary defensive facilities to safeguard its own security” and that the rest of the world had “no grounds for criticism.”
The remarks appeared to acknowledge what satellite analysts and regional governments have long suspected: that China’s island-building campaign in the South China Sea is aimed at projecting military power, not just conducting civilian research.
Regional tensions
The Paracel Islands are claimed in whole or in part by China, Vietnam, and Taiwan. China has occupied the islands since 1974, when it expelled South Vietnamese forces. The U.S. has repeatedly criticized China’s land reclamation efforts in the South China Sea, calling them destabilizing to regional security.
China has defended its activities as lawful construction within its own territory, insisting it has the right to build whatever it deems necessary on islands it considers its own.
The new construction on Yagong Island comes as China continues to expand its presence across the South China Sea, a vital waterway through which roughly a third of global shipping passes. The area is also rich in fisheries and potentially significant oil and gas reserves.
Vantor’s latest images suggest the pace of construction has not slowed despite international criticism and ongoing legal disputes over China’s claims in the region. A 2016 international tribunal ruling rejected China’s historic claims to most of the South China Sea, but Beijing has refused to recognize the ruling.
The combination of a large expanded reef and a supporting outpost on Yagong Island would give China a formidable military presence in the central Paracels, with radar coverage, potential missile systems, and a harbor capable of hosting naval vessels.
Analysts say the proximity of the two facilities — less than nine miles apart — would allow them to function as a single military complex, with Yagong serving as a forward radar and communications post for the larger base at Antelope Reef.
Still, the exact nature of the Yagong Island structures remains unclear from satellite imagery alone. Vantor noted the buildings resemble radar and early warning facilities seen elsewhere in the South China Sea, but ground-level confirmation has not been possible.
China’s Defense Ministry has remained silent on the specifics, and state media has offered only blanket assurances of peaceful, civilian purposes — assurances that regional governments and Western analysts have repeatedly questioned.
The Global Times’ own expert, Ding, appeared to undercut those assurances by conceding that military facilities on the islands would not only be plausible but completely justified under China’s security needs.
“It is entirely reasonable for China to deploy necessary defensive facilities to safeguard its own security,” Ding said. “The international community has no grounds for criticism.”
Whether that statement was a slip or a signal, it acknowledged a possibility Beijing otherwise refuses to address directly: that the construction accelerating across the Paracels is military in nature, and China has no intention of stopping.
