GAO flags cost overruns and delays in key B-52 modernization projects
A GAO report finds that most of the 13 B-52 upgrade programs are over budget, behind schedule or underperforming, with engine and radar upgrades hit hardest.
A new Government Accountability Office report reveals that ten of the thirteen programs meant to extend the service life of the Air Force's 76 B-52 bombers are either over budget, delayed, or not delivering expected performance. The most expensive initiatives—new engines and upgraded radar—are suffering on all fronts, with engine costs up 38% to more than $15 billion and development lagging 32 months, while radar spending has risen over 30% to $2.9 billion.
A fatal crash of a test B-52 at Edwards Air Force Base in June, which killed all eight aboard, further complicated the radar effort. The GAO urges the Air Force to defer engine production until the recent overruns are fully examined; the service only partially agreed. Funding pressures persist as the 2027 defense request seeks $480 million for B-52 upgrades amid broader budget constraints and a congressional stopgap that limits new Pentagon programs.
Why it matters
Delays and cost growth in B-52 upgrades could reduce the U.S. bomber fleet’s readiness and strain defense budgets.
