Vietnam occupies between 49 and 51 outposts (the status of two construction projects on Cornwallis South Reef is unclear) spread across 27 features in the South China Sea. These include facilities built on 21 rocks and reefs in the Spratly Islands, along with 14 isolated platforms known as “economic, scientific, and technological service stations,” or Dịch vụ-Khoa (DK1), on six underwater banks to the southeast that Hanoi does not consider part of the disputed island chain (though Beijing and Taipei do). In recent years, Vietnam has reclaimed new land at 8 of the 10 rocks it occupies, and built out many of its smaller outposts on submerged reefs and banks.
