DHS says it, along with the Department of Transportation (DOT) and the Department of War (DOW), is launching a coordinated airspace security effort along the southern U.S. border. The announcement says the goal is to reduce risks from unauthorized drone activity and protect federal personnel and facilities.
The measure is a temporary flight restriction (TFR) for drones. DHS says it will bar unauthorized drone operations from the surface up to 400 feet above ground level within one nautical mile north of the U.S.-Mexico border.
DHS also says the TFR is meant to support ongoing border security operations and strengthen enforcement against people who violate the restrictions. The agencies describe the action as part of broader efforts to counter threats they associate with cartel activity.
DHS notes that the FAA will publish a NOTAM with the specific notice and related links, including information connected to the FAA’s UAS Data Delivery System. Drone operators are responsible for checking the NOTAM and any other applicable restrictions before flying.
Because the excerpt does not include the full NOTAM text, readers should confirm the exact boundaries, dates, and any exceptions directly in the FAA notice referenced by DHS.
