美国DOT/战争部/DHS宣布在美墨边境对无人机实施临时飞行限制，提及定向能武器击落威胁无人机

Temporary flight restriction will prohibit unauthorized drone operations within one nautical mile of the U.S.-Mexico border, from the surface to 400 feet
The U.S. Department of Transportation (DOT), Department of War (DoW) and Department of Homeland Security (DHS) today announced a new, coordinated effort to strengthen airspace security along the southern U.S. border through a temporary flight restriction (TFR) for drones. The TFR — effective today — will bar any unauthorized drone activity up to 400 feet above ground level and extend one nautical mile north of the U.S.-Mexico border.
The move builds on the Trump Administration's successful efforts to secure the southern border and defend the homeland from national security threats — including illicit cartel activity. The new measure will reduce risks to ongoing border security operations, protect federal personnel, facilities and the Homeland, and enhance enforcement against those who violate the restrictions.
"President Trump promised to secure the Southern Border, and he did. Now we're doubling down on that promise by protecting our skies from cartel drone threats and other illicit activities," said U.S. Transportation Secretary Sean P. Duffy. "I appreciate the close collaboration with our partners at DHS and DoW as we work together to defend our airspace and keep the American people safe."
"The United States government will maintain 100% operational control of our border: land, air, and sea," said Secretary of War Pete Hegseth. "For too long, cartels have taken advantage of gaps along our southern border. Thanks to President Donald J. Trump, those days are over. By restricting unauthorized drone activity, we are giving commanders greater awareness, greater decision space, and more options to defend the Homeland. Equipped with cutting-edge technology — including Directed Energy Weapons — our warfighters will shoot down any cartel drone that threatens America's sovereignty."
"DHS will not stop building on the historic progress made to secure the southern border," said Secretary of Homeland Security Markwayne Mullin. "This action will help counter cartel drone threats, protect our personnel, and strengthen security in the airspace above the border. President Trump promised to secure the border, and we are delivering on that promise through continued action and strong partnership with Department of Transportation and the Department of War."
