Unknown Drones Sighted Over Diego Garcia Prompting Base Curfew Near Fuel Farm

BLUFUnattributed drone activity near Diego Garcia's fuel farm signals that an adversary can reach and surveil the base underpinning U.S. sustained operations across the Indian Ocean.

The unofficial Air Force amn/nco/snco Facebook page reported on August 7 that drones had been spotted near the fuel farm at Diego Garcia, and that the joint U.S.-U.K. base had been placed on a curfew from 0700 to 1900 until further notice 12. A follow-up post on Sunday displayed what it described as an official curfew schedule for locations across the installation 12. The U.K. Ministry of Defence confirmed Monday it was "aware of reported sightings of drones (UAS) over Diego Garcia" but declined to detail the situation, while a U.S. Pacific Command official said Friday the U.S. does not discuss specific force protection measures 12. Neither agency specified the drone type, timing, operator, or any defensive response, and The War Zone said it could not independently confirm the Facebook posts' accuracy 1. Diego Garcia was struck in March by Iranian ballistic missiles that failed to hit the base, one intercepted and one that malfunctioned, and F-16s were deployed to the atoll in February specifically to defend against drone and cruise-missile threats 1.

Analysis
Unidentified aircraft entered airspace near Diego Garcia's fuel farm and command imposed a twelve-hour curfew before either government would confirm drone type, origin, or intent; the U.K. Ministry of Defence's acknowledgment without denial narrows the field to a real incursion or an internal report serious enough to force public comment, though the account rests on a single primary outlet (The War Zone, merely republished elsewhere) and may instead reflect unverified rumor from an unofficial Facebook page never corroborated by either government. Given the atoll's role as bomber staging ground, submarine port, and prepositioning hub, and persistent silence on operator and system type, ship- or submarine-launched drones remain an open explanation rather than a ruled-out one for any surveillance or strike run against fuel infrastructure.
