The Pentagon's effort to accelerate the development and deployment of new weapons systems may be compromising its ability to ensure these systems are thoroughly tested and effective. A recent Government Accountability Office (GAO) report found that the Pentagon's independent testing office, the Office of the Director, Operational Test and Evaluation (DOT&E), is struggling to keep pace with the increased speed of weapons development.
The GAO report, based on an audit conducted from January to June 2026, identified significant reductions in DOT&E's workforce and budget, which have limited its ability to oversee the development of new weapons systems. The report noted that DOT&E's oversight list had decreased from 265 programs in fiscal 2024 to 173 in fiscal 2025, a drop of more than 90 programs.
The reduction in oversight capacity increases the risk that weapon systems may be fielded with undocumented shortfalls related to effectiveness, suitability, survivability, or lethality. The GAO's findings have raised concerns among lawmakers, with Senate Armed Services Committee Ranking Member Jack Reed warning that the reorganization could leave DOT&E unable to adequately oversee critical defense programs.
