National Airport Supersonic Readiness Act of 2025

This bill tells the FAA, working with NASA and other experts, to study whether major U.S. airports are ready to handle very fast passenger planes, like supersonic and hypersonic aircraft. It notes these planes could cut long flight times, but many airports may not yet have the right runways, equipment, or rules to support them safely and efficiently.

The study must review runway length and strength, fueling and maintenance needs, air traffic control systems, and environmental rules such as noise and emissions. It also has to weigh possible economic benefits and challenges. Within one year of the law taking effect, the FAA must send Congress a report with results, suggested policy and infrastructure changes, cost estimates, and a timeline.

• Who is affected: The FAA, large “hub” airports (major airports), travelers, and communities near these airports. “High-speed aircraft” means planes faster than Mach 1; “supersonic” is Mach 1 to 5, and “hypersonic” is over Mach 5.
• What changes: No immediate changes to airport operations. This creates a study and a plan with recommendations and costs.
• When: The report is due within one year after the law is enacted.
