The Pentagon says more testing is required to demonstrate that the 25mm automatic cannon mounted internally on the F-35A variant of the Joint Strike Fighter is indeed now an effective weapon. Various software and hardware issues had long left the stealthy jets unable to shoot straight, but fixes intended to resolve them have been implemented.
New questions about the actual effectiveness of the F-35A’s internal gun emerged last month after the Project on Government Oversight (POGO), an independent nonprofit, published a heavily redacted declassified copy of a report on the Joint Strike Fighter program from the Pentagon’s Office of the Director of Operational Test and Evaluation (DOT&E). POGO obtained the document, which is dated February 2024, via the Freedom of Information Act (FOIA) and provided its own analysis of the contents. The report also underscored long-standing maintenance and logistics challenges that have contributed to historically low readiness rates across all variants of the F-35 and that could have worrisome impacts on future combat operations. The War Zone has explored those issues and their broader ramifications in detail in a past feature.
“The F-35 lethality assessment suffered from the inability of the F-35’s gun to hit the targets because of design and installation issues,” according to an unredacted section of the February 2024 DOT&E report that POGO obtained.
