evidence: Vietnam has significantly accelerated the expansion of its outposts in the Spratly Islands over the last six months, creating almost as much new land as it had in the previous two years combined and putting Hanoi on pace for a record year of island building in 2024. [...] The feature now measures 4,318 meters in length, which makes it the only Vietnamese outpost so far with the potential to host a 3,000-meter runway like those that China has at Fiery Cross, Mischief, and Subi Reefs. Currently, Vietnam’s only airstrip in the Spratly Islands is a 1,300-meter runway on the eponymous Spratly Island. While that runway is large enough for most Vietnamese military aircraft, a 3,000-meter runway would be required for larger military transport, surveillance, or bomber aircraft to take off and land. [...] Trenches and coastal defense emplacements typical of Vietnam’s Spratly outposts can be seen underway at several features. And temporary helipads have appeared across many of the expanding features, including Discovery Great Reef, Ladd Reef, Tennent Reef, and South Reef.
