China builds 1,500-acre artificial island at Antelope Reef with port and runway prep

Satellite imagery shows China rapidly dredged and reclaimed ~1,500 acres at Antelope Reef in ~10 months, creating a deep-water port/quay for warships and grading for a ~10,000-foot military-grade runway plus likely hangar footprint. The novelty is the speed/scale of land-reclamation enabling a new forward A2/AD outpost (surveillance, basing, logistics) in the South China Sea.
