Satellite Images Confirm Structure at Scarborough Shoal Entrance Before Disappearing, Philippines Investigating

Analysis
The disappearance before June 1 limits immediate escalation. The sequence, with a structure emplaced, observed by two independent satellite providers, and removed under diplomatic scrutiny, mirrors the April floating barrier episode and suggests Beijing is probing Philippine and US response thresholds rather than committing to durable infrastructure. The 6-by-6-meter footprint Gen. Brawner described is consistent with a redeployable navigation marker. The object may instead have been drift debris, consistent with Teodoro's own acknowledgment that buoys occasionally enter the shoal from outside. Moderate confidence rests on convergent imagery from two independent providers, though Reuters' exclusive access to the Vantor frames makes the remaining outlets amplification rather than corroboration. Confirmed emplacement before September 4 is unlikely, but if confirmed, Manila must decide whether to contest it physically as Washington assesses Mutual Defense Treaty thresholds.
