National Airport Supersonic Readiness Act of 2025

H.R. 4012, the National Airport Supersonic Readiness Act of 2025, was introduced in the House (sponsor: Mr. Moore of North Carolina) and referred to the Committee on Transportation and Infrastructure. The bill directs the Federal Aviation Administration (FAA) to collaborate with NASA and other stakeholders to study whether large hub airports (including the biggest U.S. airports) are prepared to accommodate high-speed aircraft, which include supersonic (faster than the speed of sound but below five times the speed of sound) and hypersonic (faster than five times the speed of sound) airliners. The study would examine infrastructure, equipment, air traffic control, environmental rules (such as noise and emissions), and the potential economic impacts of hosting such aircraft. A report with findings, policy and infrastructure recommendations, and cost/timeline estimates must be delivered to Congress within one year of enactment. The bill establishes clear definitions (e.g., what counts as a “large hub airport,” “supersonic,” and “hypersonic”) and outlines the scope and committees involved in handling the study and any resulting policy actions. The aim is to identify what changes or investments would be needed to support high-speed air travel at major U.S. airports.
