How a $100M radar tariff exposes FAA ATC modernization's real $16B bill

On Sept. 15, 2026, FAA Administrator Bryan Bedford testified before a House subcommittee that phase one of the Brand New Air Traffic Control System (BNATCS) would cost $16 billion — $3.5 billion more than the $12.5 billion Congress appropriated in July 2025 through the One Big Beautiful Bill Act. Two days later, Reuters reported Bedford had disclosed an additional ~$100 million tariff cost on the program, and that the hit is concentrated on radar systems being purchased from suppliers with non-U.S. production footprints.

Bedford said the FAA is funding the gap out of its facilities and equipment budget. The Government Accountability Office, in a report dated Sept. 14, 2026 (GAO-26-107992), said the agency has not produced a reliable lifecycle cost estimate and has not built an integrated master schedule — the program is split into 11,389 separate project schedules. The GAO also flagged that the telecommunications upgrade, originally priced at $4.75 billion, has risen to $5.91 billion, and that FAA has not budgeted for most operating costs over the life of phase one.

The $100M tariff exposure is concentrated on radar procurements, and the two awardees of the January 2026 Radar System Replacement contracts are actively moving production to U.S. soil. RTX's Collins Aerospace won a $438 million contract to install its Condor Mk3 cooperative surveillance radar; the company has committed $26.5 million to its Largo, Florida facility for the work. Indra Sistemas won a $342 million contract for next-generation surveillance radars and is building them at a new manufacturing Center of Excellence in Overland Park, Kansas, backed by a $50 million capital commitment and a separate $7.5 million, 25,000 sq ft Olathe radar plant — together creating more than 340 U.S. jobs.

Both contracts are designed to retire legacy radars — many dating to the 1980s — by June 2028. Domestic production neutralizes the tariff pass-through and puts both firms on the right side of an emerging Buy-American preference inside the program.

The Air Current reported that U.S. prime contractors — L3Harris, RTX and Leidos — have spent nearly two years lobbying for reciprocal restrictions that would lock European-owned Thales, Indra and Austria's Frequentis out of BNATCS contracts, citing a 2024 EU regulation that bars non-EU ATC suppliers. Indra has pre-empted that risk by localizing production; Thales has not, and Frequentis is positioned only on the Voice-over-IP Communications Enterprise (VoICE) program so far.

The $100M tariff is small next to the structural issues. Peraton — picked as sole prime integrator in December 2025 on a $1.5 billion, 10-year contract — is reportedly under pressure eight months in, with Politico reporting in August 2026 that the FAA is considering scope reductions. With a fragmented master schedule, no reliable operating-cost forecast, and a phase-two authorization still pending, the working-capital squeeze on the F&E line will determine whether radar and telecom deployments hit their 2028 milestones or slip into the next authorization cycle.

Tariffs reward suppliers with U.S. production and penalize those without. L3Harris has the longest-dated exposure — its surveillance contract runs through 2045 — and the highest-confidence domestic build-out (FTI on track for 2027, ~200 telecom engineers in Melbourne, FL). RTX has the largest near-term contract win ($438M radar) and is publicly bidding for an expanded BNATCS role. Leidos sits on the most mission-critical FAA software (ERAM en route automation), giving it the stickiest incumbency even if its dollar exposure to the $12.5B program is smaller. Indra is the contrarian play — foreign-owned, but already onshore in Kansas and awarded a $342M radar contract that routes around the tariff wall.
