WASHINGTON, D.C. — Reports of unidentified drones flying over Fort Lesley J. McNair are now under investigation, placing renewed attention on one of the most sensitive Army posts in the country.
According to multiple reports, several drones were allegedly observed over the Washington, D.C. installation within the past 10 days. The post houses the National Defense University and serves as a residence for senior officials, including Secretary of State Marco Rubio and Secretary of War Pete Hegseth.
Military officials have not confirmed that any drones breached restricted airspace. A spokesperson said there is currently no credible threat, and the situation remains under investigation.
The sequence of events surrounding the installation is notable.
In November 2025, Joint Interagency Task Force 401 conducted a counter-drone exercise at Fort McNair focused on detecting and responding to small unmanned aircraft in an urban environment. The exercise included a centralized tracking and coordination setup designed to monitor aerial activity across the Washington area.
Footage from that training shows military police personnel using handheld counter-drone systems during simulated engagements involving small unmanned aircraft. The system visible in the footage is consistent with the Dronebuster Block IV platform, a current-generation handheld electronic counter-UAS device.
Manufacturer materials for the system describe it as a handheld electronic attack device designed to disrupt and defeat small unmanned aircraft, and state that it is authorized for use by the U.S. Department of Defense.
The reported drone sightings now under investigation occurred months after that demonstration, at the same installation.
In a LinkedIn post approximately two months ago, a business development manager at DZYNE Technologies—the company associated with the Dronebuster platform—described earlier Block 3 systems as “2016 technology,” stating that “hundreds” remain in inventory and “need to be retired and replaced ASAP.”
In the same post, the individual described the newer Block IV model as “~7 times more powerful,” capable of jamming multiple satellite navigation systems and spoofing unmanned aircraft, and encouraged units to consider upgrades, including offering demonstrations and trade-in discounts.
The same model appears to be the system used by military police personnel during the Fort McNair training exercise.
Officials have not provided details on how the reported activity was detected, whether any counter-drone measures were employed, or what response actions—if any—were taken during the incident.
Fort McNair’s location adds another layer of sensitivity. Positioned in the heart of Washington, D.C., the installation sits near some of the most politically and militarily significant areas in the country.
Officials have not identified where the reported drones originated, who may have been operating them, or whether they posed any operational threat. The sightings were reportedly concentrated on a single night and were significant enough to prompt discussions at the White House.
The reports also come as the United States raises its security posture amid tensions involving Iran. Diplomatic posts worldwide have been instructed to review security measures, while federal agencies have warned of potential drone-related threats inside the United States.
Several military installations have already increased force protection levels, including Joint Base McGuire-Dix-Lakehurst and MacDill Air Force Base, both of which have moved to Force Protection Condition Charlie in recent days.
For now, officials maintain there is no confirmed threat to Fort McNair.
The incident adds to a growing number of drone-related reports in recent years involving sensitive U.S. locations.
At Fort McNair, the timeline is straightforward: current-generation counter-drone systems were publicly demonstrated, and months later, reports of unidentified aerial activity at the same location are now under review.
What has not been detailed is how that activity was managed, or what actions—if any—were taken in response.
