FAA Selects L3Harris to Overhaul Aging Air Traffic Surveillance Network

The Federal Aviation Administration has selected L3Harris Technologies to modernize the nation's air traffic surveillance network, a system that tracks aircraft movements across United States airspace and forms a foundational layer of the country's aviation safety infrastructure.

The contract calls on L3Harris to replace and upgrade aging surveillance equipment that has served the FAA for decades. The work forms part of a broader push by the agency to overhaul air traffic control technology, much of which relies on hardware and software installed years ago.

What the Contract Covers

Under the agreement, L3Harris will deliver next-generation surveillance systems capable of processing data from radar sites, Automatic Dependent Surveillance-Broadcast (ADS-B) stations, and other tracking sources feeding information into FAA facilities nationwide. These systems provide controllers with the real-time position data they use to separate aircraft, sequence arrivals, and manage traffic flow across the National Airspace System.

The company has held a longstanding role as a supplier of surveillance technology to the FAA, and this award extends that relationship into the next phase of the agency's modernization effort. The new equipment is designed to integrate with existing air traffic control platforms while providing improved processing capacity, redundancy, and cybersecurity protections.

Why the Upgrade Matters Now

The FAA has faced growing pressure from lawmakers, industry groups, and safety advocates to accelerate technology upgrades after a series of outages and near-miss incidents drew attention to the age of critical systems. Several high-profile disruptions in recent years, including a nationwide ground stop tied to a failure of the Notice to Air Missions system, prompted calls for faster investment in resilient infrastructure.

Surveillance sits at the center of that conversation. Controllers depend on accurate, uninterrupted position data to safely manage the tens of thousands of flights operating in US airspace each day. When surveillance feeds degrade or fail, controllers must increase separation between aircraft, which reduces capacity and can ripple through the system as delays.

The modernization is also tied to the continued rollout of ADS-B, the satellite-based tracking technology that has largely replaced traditional radar as the primary means of surveillance in many parts of the country. ADS-B allows aircraft to broadcast their position, altitude, and velocity to ground stations and other aircraft, providing more precise data than legacy radar systems.

Integration With Broader Modernization

The surveillance contract fits within a wider modernization program the FAA has outlined for its air traffic control infrastructure. That program includes replacement of aging radios, updates to controller workstations, upgrades to facility telecommunications, and consolidation of some legacy facilities into newer centers.

The Trump administration and members of Congress from both parties have called for a comprehensive rebuild of air traffic control systems, with proposals ranging from targeted equipment replacement to broader structural reforms of how the FAA delivers air traffic services. Funding for the modernization effort has drawn bipartisan support, though disagreements remain about the pace and scope of the work.

L3Harris, headquartered in Melbourne, Florida, produces a range of communications, surveillance, and mission systems for civil and defense customers. Its aviation portfolio includes air traffic management technology deployed in the United States and abroad, giving the company a technical base to draw on for the FAA project.

What Pilots and Passengers Can Expect

For pilots operating in the National Airspace System, the changes will largely occur behind the scenes. Cockpit equipment requirements are not directly affected by the new contract, though the improved ground infrastructure is expected to deliver more consistent surveillance coverage and fewer service interruptions.

Passengers stand to benefit indirectly through improved reliability. Surveillance outages have contributed to delays and cancellations in past years, and modernized equipment with better redundancy should reduce the frequency and severity of those disruptions. Controllers should also gain access to more accurate and timely position data, which supports safer and more efficient traffic management.

General aviation operators, who fly a wide range of aircraft from single-engine trainers to business jets, have expressed particular interest in the modernization effort. Many general aviation flights operate in airspace where surveillance coverage has historically been thinner than in busy commercial corridors, and improvements to the ground network could expand the areas where controllers can provide radar-like services.

Timeline and Next Steps

The FAA has not published a full public timeline for the deployment of the new equipment, but modernization programs of this scale typically unfold over multiple years as sites are upgraded one by one to avoid disrupting active operations. Contractors and the agency generally coordinate installations to occur during low-traffic periods, with cutovers to new systems handled in stages.

L3Harris will work with FAA technical teams to develop and validate the new surveillance platforms before fielding them across the network. Testing typically occurs at designated FAA facilities before broader deployment, and the agency requires extensive certification of any system that will be trusted with live traffic data.

The award marks another step in a modernization program that industry observers have described as one of the most significant infrastructure undertakings in the FAA's history. Whether the agency can execute on its plans within the timelines it has set will depend on continued funding, workforce capacity, and the technical performance of contractors like L3Harris.
