China completed construction of a 1,500‑acre artificial island at Antelope Reef in the South China Sea, as shown in satellite imagery dated August 11, 2026, released by the spatial‑intelligence firm Vantor.
Antelope Reef, known as Lingyang Jiao in China and Đá Hải Sâm in Vietnam, is located about 160 nautical miles south of Hainan and 200 nautical miles east of Da Nang. The Paracel Islands, occupied by China since 1974, are disputed by Vietnam and Taiwan.
The reclaimed land includes a deep‑water port with a quay over 2,000 feet long capable of berthing warships and a runway planned to reach 10,000 feet in length and 180 feet in width. Construction moved more than one million tons of sand in less than a year, and three dredging vessels operated continuously. The island measures 3.7 miles in length and is surrounded by seawalls and internal roads. Temporary piers, concrete plants, and a helicopter pad are present at the site. The east side hosts administrative buildings and housing, while the northwest area is prepared for runway grading that is about halfway complete.
A 680‑meter quay on the southern side can accommodate both military and civilian vessels; a China Coast Guard vessel was observed dockside at the quay in recent satellite images. Reuters reported the presence of the vessel, but Vantor has not independently confirmed the assessment.
Chinese state media said the island will be used for commercial and civilian purposes, a claim similar to statements made during the development of other outposts. In 2015, President Xi Jinping told then‑President Barack Obama that China does not intend to pursue militarization of the South China Sea. Analyst Greg Poling of the Asia Maritime Transparency Initiative said the site could enhance intelligence, surveillance and reconnaissance capabilities and allow more persistent aerial patrols, but the availability of sand may limit further large‑scale reclamation.
