Some of the radar systems guiding commercial jets across the United States are older than the pilots flying them. Now, after years of deferred upgrades, the Federal Aviation Administration is finally moving to retire hundreds of those systems in what amounts to the largest radar overhaul the agency has attempted in decades.
Under a program called the Facility Replacement and Radar Modernization initiative, or FRRM, the FAA has awarded contracts to defense firms RTX and Indra Group USA to begin replacing up to 612 radar units at terminal facilities and en route centers nationwide. Transportation Secretary Sean Duffy and FAA Administrator Chris Bedford announced the awards, setting an ambitious target of June 2028 for completion.
For the roughly 900 million passengers who board U.S. flights each year, the program’s trajectory will shape whether the air traffic control network can keep pace with rising demand or faces mounting outage risks from equipment that was never designed to last this long.
Decades-old equipment under strain
The FAA’s own budget documents describe 377 critical radar systems averaging 36 years in service as the top priority for the radar recapitalization effort. Many of these units date to the late 1980s and early 1990s, an era when the technology was state of the art but the expected service life was far shorter than what the agency has demanded of it.
The FAA’s Terminal and En Route Surveillance Technical Refresh Portfolio, known as TES TRP, lays out the agency’s current approach to keeping those aging systems running. The program page states plainly that the sustainment strategy depends on a future replacement program. Without one, the FAA has estimated that some radar units could be stretched beyond 2040, a timeline that underscores just how long controllers have been working with equipment operating well past its design horizon.
Associated Press reporting has described the maintenance burden on controllers and technicians as significant, with aging components increasingly difficult to source and repair. While the FAA has not published failure-rate statistics or outage logs for individual systems, the pattern is familiar to anyone who has followed the agency’s infrastructure challenges: critical hardware kept alive through improvisation and spare-parts scavenging.
Billions committed, but questions remain
The FRRM program is backed by mandatory federal funding spanning fiscal years 2025 through 2029, giving it a more durable financial foundation than many FAA modernization efforts that have stalled in past budget cycles. In congressional testimony on the FY 2026 budget request, then-Acting FAA Administrator Christopher Rocheleau cited a $450 million initiation request to launch the radar replacement work.
Whether Congress has approved that specific funding line as of April 2026 remains unclear from publicly available records. The $450 million figure represents a starting investment, not the total program cost, and per-vendor contract values for RTX and Indra have not been disclosed in primary FAA documents.
The scope of the replacement effort also carries an unresolved discrepancy. The FAA’s budget narrative identifies 377 systems as the critical priority, while the contract announcement references up to 612 radars. The gap likely reflects the difference between the most urgent replacements and the full universe of eligible systems, but neither the FAA nor the contractors have clarified the distinction publicly.
Indra Group USA confirmed its contract award through a press release in early January 2026, providing independent verification that procurement moved beyond the announcement stage. RTX, one of the world’s largest defense contractors, has not issued a comparable public statement, though the FAA’s announcement names both firms.
Where the new technology fits
The modernization push does not exist in a vacuum. The FAA has spent more than a decade rolling out Automatic Dependent Surveillance-Broadcast, or ADS-B, a satellite-based tracking system that supplements traditional radar by allowing aircraft to broadcast their own position data. ADS-B coverage reached a nationwide mandate for most airspace in 2020.
But radar remains essential. ADS-B depends on aircraft carrying functioning transponders, and radar provides an independent layer of surveillance that controllers rely on when transponder data is unavailable, unreliable, or when tracking non-equipped aircraft. Replacing aging radar systems is not about choosing between old and new technology. It is about ensuring that the foundational layer of air traffic surveillance does not degrade while newer systems mature.
The next-generation radar units are expected to offer improved reliability, lower maintenance costs, and better integration with digital air traffic management platforms. Specific technical specifications for the replacement systems have not been published by the FAA as of this writing.
What to watch through 2028
The June 2028 completion target announced by Duffy and Bedford should be understood as an aspirational deadline rather than a binding contractual obligation verified through procurement records. Large-scale FAA technology programs have a history of delays, from the long-troubled NextGen initiative to earlier terminal automation upgrades that ran years behind schedule.
For airlines, airport authorities, and the traveling public, the practical indicators to track are straightforward: congressional action on the FY 2026 and FY 2027 budget lines that fund FRRM, FAA updates on delivery milestones for the first radar installations, and any inspector general or Government Accountability Office reviews that assess whether the program is meeting its benchmarks.
The stakes are not abstract. Every flight in U.S. airspace depends on controllers having a reliable picture of where aircraft are. With traffic volumes climbing and the existing radar fleet aging by the month, the FRRM program represents the FAA’s clearest commitment in years to closing the gap between the technology controllers need and the technology they actually have.
