GAO Reports Billions in B-52 Modernization Cost Overruns

The Government Accountability Office reported that the US Air Force's B-52 Stratofortress modernization program is facing billions of dollars in cost overruns and significant scheduling delays. Of the 13 planned upgrades, 10 are currently experiencing performance or cost challenges.

The Commercial Engine Replacement Program, the most expensive element of the effort, has seen costs increase by approximately $3 billion since 2023. Its operational date has been pushed back by more than 15 months. The GAO warned that the Air Force plans to begin engine production with minimal developmental flight testing and recommended delaying that decision to better analyze risks.

These upgrades, which include new radars, communications systems, and the capacity to carry the AGM-181 Long-Range Standoff nuclear-armed cruise missile, are designed to keep the 70-year-old bombers operational into the 2050s. These capabilities remain critical for strategic deterrence and active combat operations. Dan Caine, Chairman of the Joint Chiefs of Staff, recently noted the aircraft's utility in combat operations over Iran, stating that air superiority has allowed for the first overland B-52 missions to get on top of the enemy.
