交通部、战争部与国土安全部联手护边境空域：美墨边境以北1海里设无人机临时限飞 即日生效
华盛顿——美国交通部（Department of Transportation, DOT）、战争部（Department of War）与国土安全部（DHS）10月16日发表联合声明，对美墨边境沿线空域实施无人机临时飞行限制（TFR），宣布当日即时生效：边境以北1海里、地表至400英尺（约122米）空域内，未经授权的无人机活动一律禁止。
三部门称，此举旨在降低对正在进行的边境安全行动的风险、保护联邦人员与设施，并加强对违规者的执法。联邦航空管理局（FAA）将发布航行通告（NOTAM）载明限制细节；无人机操作者有责任在飞行前查阅全部适用通告。国防部官员表示，美墨边境沿线每月有超过1,000次无人机侵入，美方安全官员对贩毒集团利用无人机投送毒品包裹、侦察走私路线日益警惕。
交通部长 Sean P. Duffy 说：「特朗普总统承诺守住南部边境，他做到了。现在我们加倍兑现这一承诺——保护我们的天空免受卡特尔无人机威胁。」战争部长 Pete Hegseth 表示，限制未经授权的无人机活动能给指挥官「更大的态势感知、决策空间与保卫国土的选项」，并称美军「将击落任何威胁美国主权的卡特尔无人机」。国土安全部长 Markwayne Mullin 称，此举将「帮助应对卡特尔无人机威胁、保护我们的人员」。（GSM 据三部门10月16日联合声明与路透社报道）
DOT, Department of War and DHS Impose Drone Flight Restriction Along the U.S.-Mexico Border, Effective Immediately
WASHINGTON — The U.S. Department of Transportation (DOT), the Department of War and the Department of Homeland Security (DHS) on October 16 issued a joint statement imposing a temporary flight restriction (TFR) on drones along the U.S.-Mexico border, effective immediately: unauthorized drone activity is barred from the surface to 400 feet (about 122 meters) above ground level, extending one nautical mile north of the border.
The departments said the measure will reduce risks to ongoing border security operations, protect federal personnel and facilities, and enhance enforcement against violators. The Federal Aviation Administration (FAA) will publish a Notice to Airmen with the restriction details, and drone operators are responsible for reviewing all applicable notices before flying. Pentagon officials say there are more than 1,000 drone incursions along the U.S.-Mexico border each month, and U.S. security officials have grown increasingly alarmed about cartels using drones to drop drug packages and surveil trafficking routes.
"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 Transportation Secretary Sean P. Duffy. Secretary of War Pete Hegseth said restricting unauthorized drone activity gives commanders "greater awareness, greater decision space, and more options to defend the homeland," adding that U.S. forces "will shoot down any cartel drone that threatens America's sovereignty." Homeland Security Secretary Markwayne Mullin said the action "will help counter cartel drone threats, protect our personnel, and strengthen security in the airspace above the border."
