Marine Corps Base Camp Pendleton in southern California experienced multiple drone incursions over its airspace over the past several days, a facility spokesman told The War Zone on Tuesday morning.

Between Dec. 9 and 15, “there were six instances of unmanned aerial systems (UAS) observed entering Camp Pendleton’s airspace, with no threat to installation operations,” Capt James C. Sartain, a base spokesman, told The War Zone in response to our query on the matter.

Sartain could not immediately provide details about how many drones flew over the installation, their origin, what actions were taken in response and if any air or ground operations were affected as a result of the incursions. We have asked for these details and will update this story should any be provided.

Located in north San Diego County, MCB Camp Pendleton is the Marine Corps’ major west coast training facility. It is home to the 1st Marine Expeditionary Force, 1st Marine Division, 1st Marine Logistics Group, elements of the 3rd Marine Aircraft Wing,

and several other tenant units including Marine Corps Air Station Camp Pendleton, ACU-5, Naval Hospital, the Marine Corps Tactical Systems Support Activity (MCTSSA), Weapons Field Training Battalion, Naval Weapons Station Fallbrook, and the Deployment Processing Command Reserve Support Unit – West).

This is just the latest in a growing string over incursions reported over U.S. military installations at home and abroad.

News about MCB Camp Pendleton follows a drone incursion over Wright-Patterson Air Force Base in Ohio forcing the closure of its airspace Friday night into Saturday morning.

The War Zone was the first to report that incident. On Tuesday, Wright-Patterson officials announced that there were additional incursions over the facility.

“Small unmanned aerial systems were spotted in the vicinity of and over Wright-Patterson AFB’s Area A and Area B during the late evening and early morning of Dec. 16 and Dec. 17th,” the 88th Air Base Wing said in a statement.

“Installation leaders have determined that none of the incursions impacted base residents, facilities or assets. The Wright-Patterson AFB airspace was not affected by the incursions.”

“The number of systems has fluctuated, and they have ranged in sizes and configurations,” the release added. “Our units continue to monitor the airspace and are working with local law enforcement authorities and mission partners to ensure the safety of base personnel, facilities and assets.

We request individuals in the area to contact either local police or Security Forces if they see anything suspicious, to include sUAS’s or drone activity.”
