"I think you’ll find that we have stabilized the cost and schedule," William Bailey told a House subcommittee, putting a point on months of turbulence in the B-52 modernization effort.
William Bailey’s assessment to the House subcommittee
Bailey, who is performing the duties of the Air Force’s acquisition czar, testified before the House Armed Services seapower and projection forces subcommittee that he had met with government and industry officials "to get to the bottom of what’s been going on [with] the program" to upgrade the B-52 Stratofortress and that he was satisfied with the results. Rep. Clay Higgins, R-La., pressed the point that the program involves "a lot of money" and warned that some members of Congress "watch that money very carefully," saying they would "rather see the appropriate amount of money authorized and appropriated than to see cost overruns." The Air Force did not respond by press time when asked for updated cost and schedule estimates.
B-52 Commercial Engine Replacement Program: costs, schedule, and the path to flight testing
One of the principal modernization efforts replaces the bomber’s eight Pratt & Whitney TF33 engines with Rolls-Royce F130 powerplants. According to Air Force officials cited in 2024, that Commercial Engine Replacement Program is now expected to cost about $15 billion, up from an earlier estimate of $12.5 billion. Government Accountability Office assessments show the upgrade’s targeted initial operational capability has slipped roughly three years to 2033. The Air Force announced earlier this month that the program passed a critical design review, a milestone the service said paves the way to modify aircraft for flight testing.
Radar upgrade: a Nunn-McCurdy breach and a later fielding date
The B-52’s radar modernization has also experienced cost growth and delays. Last year the radar effort suffered what’s known as a Nunn-McCurdy cost breach; one member of Congress said that breach entailed a 17 percent hike per unit. The Air Force has said that a finalized cost estimate was not available at the time, though officials had previously pegged the radar’s price tag at around $3.3 billion — roughly $1 billion higher than earlier estimates. The Government Accountability Office now projects radar fielding in 2030, a delay of about three years.
B-1 and B-2: extended life, FY27 investments, and new payloads
The B-52 work sits inside a broader roadmap that envisions a two-bomber fleet consisting of the B-21 Raider and the B-52, with the B-1 Lancer and B-2 Spirit slated for retirement eventually. But budget documents and witness testimony show both the B-1 and B-2 will remain in service longer than previously planned. Fiscal 2027 materials and written testimony from Bailey and Air Force Lt. Gen. David Tabor say the FY27 budget will invest nearly $433 million to equip 44 B-1s with upgrades including satellite communications and external pylons, plus $27 million to integrate a hypersonic glide weapon dubbed ARRW. Another roughly $744 million in FY27 would be spent on the 19-aircraft B-2 fleet. The B-2s were used, the record notes, to strike Iranian nuclear facilities last year, and Air Force officials now say the bomber "will remain in service as long as necessary," according to Air & Space Forces Magazine.
What this means for Boeing, Rep. Clay Higgins, and the Air Force acquisition community
- Boeing: The company is named as the prime contractor for both the engine replacement and the radar modernization. Program stability, as characterized by Bailey, will hinge on Boeing’s ability to hold to the redesigned schedules and to execute work that has already undergone a critical design review.
- Rep. Clay Higgins and Congress: Higgins’s remarks underscore a watchful posture on appropriations. His stated preference for "the appropriate amount of money authorized and appropriated" over cost overruns signals that future funding decisions will be scrutinized against revised cost and schedule baselines.
- The Air Force acquisition community: Bailey’s meetings with government and industry and his public statement of stabilization indicate internal focus on getting the programs under control. The next contract and test milestones — notably modification for flight testing after the engine program’s critical design review — will be the near-term proof points.
Analysis of Alternatives, classified work, and the near-term checklist
Fiscal 2027 documents also reveal a plan for a heavy bomber Analysis of Alternatives, reported by Aviation Week, to explore future long-range strike requirements and potential new heavy bomber configurations. In a statement to Breaking Defense the Air Force spokesperson said, "The Air Force has not changed its program of record and remains committed to a future two-bomber fleet comprised of the B-21 and B-52. The Air Force continues to assess future long-range strike requirements and what capabilities may be needed beyond currently fielded and planned systems. As part of that deliberate planning process, the Air Force is conducting an Analysis of Alternatives to help inform potential future options." The spokesperson added the analysis is classified, typically takes about 18 months to complete, and that more information would not be available while the process plays out.
The record is now a ledger of milestones and questions: a critical design review cleared for the engine replacement and the path to flight testing; GAO timelines that push both major upgrades into the next decade; budget lines that prolong the lives of the B-1 and B-2; and a classified study that could reshape long-range strike planning. For Congress, Boeing and Air Force acquisition leaders alike, the coming months will test whether stabilization means simply arresting cost growth or whether it means delivering upgraded aircraft on the new, agreed schedules — and on-budget.
