GAO Highlights Challenges in B-52 Modernization ProgramThe US Government Accountability Office (GAO) has warned that the US Air Force’s $21-billion modernization effort for the B-52 Stratofortress faces significant financial and technical obstacles. Ten of the thirteen planned upgrades designed to keep the bomber operational through 2050 are experiencing delays, increasing costs, and execution risks. The most pressing issue is the Commercial Engine Replacement Program (CERP), whose budget has risen by approximately $3 billion since 2023 to reach $15.4 billion. The program has also encountered a 15-month delay, creating concerns about aircraft availability. The GAO noted that maintenance depots are already experiencing shortages of spare parts for the aging Pratt & Whitney TF33 engines currently powering the fleet. Continued delays could create operational capability gaps affecting the Air Force’s remaining 76 active bombers. Although the Air Force intends to begin engine production before completing developmental flight testing, the GAO cautioned that doing so increases the risk of costly redesigns. The watchdog recommended postponing production decisions until additional risk assessments are completed. While the Air Force accepted five of the GAO’s six recommendations, it only partially agreed with delaying production.
