GAO finds B-52 modernization programs over budget and delayed

A report from the Government Accountability Office (GAO) found that ten of the thirteen programs designed to modernize the B-52 bomber fleet are over budget, behind schedule, or underperforming. The Air Force is spending an estimated $21 billion to extend the lifespan of its 76 aging bombers into the 2050s.

The two most expensive programs, engine replacement and radar upgrades, are facing significant setbacks. Costs for the engine program have risen 38% since 2018 to over $15 billion, with development delayed by 32 months and flight testing four years behind schedule. The radar program has seen costs increase by over 30% to $2.9 billion.

In June, a B-52 involved in the radar testing effort crashed during takeoff at Edwards Air Force Base, resulting in eight fatalities and the destruction of one of two planned test aircraft.

The GAO recommended that the Air Force delay engine production until it addresses these cost and schedule issues. The watchdog warned that starting production before flight testing is complete increases the risk of expensive rework and could eventually lead to "too few B-52s to support operational requirements."
