Drones of an unknown origin were reportedly sighted over the remote joint U.S.-U.K. Diego Garcia installation located deep in the Indian Ocean. As we have frequently reported, this island base has long been a highly strategic operating location for the U.S. military. Beyond its large airfield that has been an epicenter of bomber operations over the decades, it plays many roles for the Pentagon. These include hosting Space Force operations, serving as a key port for U.S. Navy vessels, including nuclear submarines, and its lagoon provides shelter for a Sealift Command Prepositioning Ship Squadron.
The installation was targeted by Iranian ballistic missiles during the Epic Fury operation, but the threat posed by drones is even more plausible for the island outpost, especially at this extremely tense time as the standoff between the U.S. and Iran grinds on.
The issue of reported drones over Diego Garcia highlights a plausible threat of sea-launched drones that TWZ has been drawing attention to for years now. It also again raises concerns about the danger to critical infrastructure and aircraft parked in the open at Diego Garcia and many other U.S. installations. This is another issue TWZ has been highlighting for years.

“We are aware of reported sightings of drones (UAS) over Diego Garcia,” the U.K. Defense Ministry (MoD) told us Monday morning. “We are unable to provide any details about a situation which may affect the security or operation of the joint U.K.-U.S. base on Diego Garcia.”
“The U.S. and U.K. Commanding Officers on Diego Garcia consider and implement appropriate measures to ensure the security and safety of the base and the safety of the personnel on the island,” MoD added.
U.S. officials were less forthcoming.
“As a matter of operational security, we do not discuss specific force protection measures or security procedures at U.S. military installations,” an official from U.S. Pacific Command (PACOM) told us on Friday. “We remain vigilant in protecting U.S. personnel and facilities.”

Neither MoD nor PACOM would say what kinds of drones were sighted, when they were sighted, who was operating them or what, if any, defensive measures were taken as a result. Both military organizations were responding to our questions about an Aug. 7 posting on the Air Force amn/nco/snco Facebook page, an unofficial social media channel that posts about service topics.
“Inbox: ‘Diego Garcia. Drones spotted near fuel farm. Base on 0700 to 1900 curfew until further notice’ Note: message us if you have further information, thanks,” the post read.

On Sunday, the page published a second post on the topic titled "Diego Garcia Curfew reportedly due to Drone Threats." The post displayed what the page purported to be an official listing of curfew times for various locations around the installation.

We cannot independently confirm the accuracy of these posts and have reached out to MoD and PACOM for details. MoD did not specify who reported the drone sightings over Diego Garcia, so we have asked for clarification. Making this an even more unusual event, Diego Garcia is essentially a closed island with no significant general population or tourists around to be operating drones on a recreational basis. So seeing one or more over the base would certainly raise alarms.
Though Diego Garcia is about 1,000 miles from Sri Lanka, the nearest large landmass, its remote location does not rule out the possibility of drone incursions by an...
