The flight endurance that decides whether an American drone needs a national security export licence goes from 30 minutes to 3 hours, and the rule took effect the day before the issue carrying it

Thirty minutes.

That was the flight endurance above which an unmanned aerial vehicle attracted national security controls under the Export Administration Regulations. From Thursday it is three hours. The Bureau of Industry and Security filed a final rule, RIN 0694-AK30, which also eliminates wind gust tolerance as a parameter for deciding whether a drone is controlled in the first place.

The rule strips the national security reason for control off software and technology tied to drones with an endurance under three hours, and off certain specially designed parts, components, accessories and attachments for those aircraft, which the bureau states do not provide any significant military or intelligence capabilities. Military end-use and end-user controls on the shorter endurance drones stay. Aircraft with an endurance of three hours or greater remain controlled in ECCN 9A012 for national security reasons, and some of the technology below that line remains controlled for missile technology reasons.

The reasoning the document gives

The bureau writes that the existing controls are ineffective because drones performing at the current thresholds are now readily available on the global commercial market. It goes further on the technology: the software and knowhow needed to design a drone capable of 60 minutes or more of flight are, in its words, globally commercially widespread, taught in universities and embedded in open-source development communities.

The paperwork this removes is small and the bureau says so. It estimates a decrease of 30 licence applications a year.

The rule follows an interim final rule published on January 21, which drew 12 comments, nine of them substantive. Both trace back to section 8(a) of Executive Order 14307 of June 6, 2025. Neither went out for notice and comment, and neither had to: the bureau cites section 1762 of the Export Control Reform Act, which exempts this kind of action from the notice, participation and delayed effective date requirements of the Administrative Procedure Act. That exemption is why the effective date is August 13 while the Federal Register issue carrying the rule is dated August 14.
