The Federal Aviation Administration (FAA) and the United States Department of Transportation (DOT) have announced an ambitious initiative to fully modernize the United States air traffic control (ATC) system, aiming to improve safety, reduce delays, and prepare the infrastructure for the future of aviation.

The program will replace critical infrastructure such as radar systems, software, hardware, and telecommunications networks, creating a more reliable system for air traffic controllers and more efficient flight operations.

Authorities expect the new system to be fully implemented by the end of 2028, using an innovative contract structure designed to hold the prime integrator accountable for delays or performance issues.

Key Modernization on areas

The initiative is structured around six major workstreams:

Communications

• Converting copper lines to fiber and wireless networks
• Transitioning from analog systems to digital IP-based communications
• Replacing voice switches to improve controller-pilot communications
• Upgrading radios to ensure interference-free communication

Surveillance

• Replacing aging radar systems
• Improving tracking of aircraft and ground vehicles
• Installing surface movement radar systems at complex airports

Automation

• Deploying the Terminal Flight Data Manager, eliminating paper flight strips
• Implementing new real-time operational data systems

Facilities

• Replacing aging Air Route Traffic Control Centers (ARTCC)
• Modernizing TRACON facilities

Alaska airspace

• Installing new weather and visibility systems
• Expanding programs that prioritize better-equipped aircraft

Additional systems

• Deploying remote digital control towers
• Installing new controller training simulators

Key Numbers of the modernization program

The infrastructure upgrade includes significant investments:

• 27,625 new radios
• 5,170 high-speed network connections (fiber, satellite, wireless)
• 612 next-generation radar systems
• 462 digital voice switches
• 110 additional weather stations in Alaska
• 1 new consolidated Air Route Traffic Control Center, the first new center built since the 1960s

These upgrades are expected to strengthen aviation safety, increase system efficiency, and prepare U.S. airspace for emerging technologies such as autonomous aviation, drones, and advanced air mobility.
