The United States is embarking on a new phase in aerospace innovation, aiming to regain its leadership in supersonic flight. President Donald J. Trump has issued an order to reform regulations that have restricted supersonic travel over land for over five decades. The move is expected to enhance American competitiveness and foster technological advancements in the field.
The order directs the Federal Aviation Administration (FAA) to repeal outdated prohibitions on overland supersonic flight and establish new noise-based certification standards. "The Administrator of the Federal Aviation Administration (FAA) shall take the necessary steps, including through rulemaking, to repeal the prohibition on overland supersonic flight in 14 CFR 91.817 within 180 days of the date of this order," it states.
Within 18 months, the FAA is tasked with proposing rules for noise certification of supersonic aircraft under 14 CFR Part 36. These rules will consider factors such as community acceptability and technological feasibility. "The proposed rule shall define acceptable noise thresholds for takeoff, landing, and en-route supersonic operation based on operational testing and research," according to the order.
In addition to regulatory changes, the directive calls for coordinated research and development efforts led by the Office of Science and Technology Policy (OSTP). This includes identifying needs for regulatory development and integrating supersonic aircraft into national airspace. "The Director of OSTP shall provide the results of the coordinated efforts...to inform the development of future procedures, regulations, and policies," it notes.
International cooperation is also emphasized, with instructions for engaging with global partners to align regulatory approaches on civil supersonic flight. The Secretary of Transportation will work through the FAA to secure bilateral aviation safety agreements necessary for international operations.
The order concludes with general provisions ensuring it does not affect existing legal authorities or create enforceable rights against U.S. entities.
Donald J. Trump signed this initiative at The White House on June 6, 2025.
