The U.S. has proposed a $35 billion plan to modernize its outdated air traffic control system by 2028, addressing failures in regions like Alaska, Newark, and Washington, D.C. The initiative aims to replace outdated radar, communication systems, and infrastructure, enhancing safety, reducing delays, and improving overall efficiency to meet growing air travel demands. The overhaul will include upgrades to 200 airports and installation of 25,000 radios and new radar systems.
