Pentagon Removes All Public Weapons Testing Reports From DOT&E Website Citing AI Vulnerability Concerns as Staff Cut 74 Percent

BLUFRemoving public weapons testing data while cutting 74 percent of the evaluators makes restoration of independent oversight very unlikely by October 31 and shifts acquisition accountability behind closed doors.

The Pentagon's independent weapons testing office removed all unclassified annual reports on major weapons systems from its public website, transitioning them on July 30 to a Common Access Card-enabled network accessible only to authorized personnel 12. A defense official told Federal News Network the move addresses concerns that adversaries could use AI and automated data aggregation to compile the reports into vulnerability profiles targeting US defense capabilities 2. The change follows a May 2025 memo from Defense Secretary Pete Hegseth that cut the Office of the Director, Operational Test and Evaluation's staff by 74 percent, from 126 authorized civilian positions to 30, and its budget by nearly 80 percent 34. Senator Elizabeth Warren and Representative Donald Norcross cited a Government Accountability Office finding that the staffing cuts increased the risk of weapons reaching troops with undocumented shortfalls in effectiveness, suitability, survivability, or lethality, and requested that Hegseth restore the reports and respond to Congress by August 26 4.

Analysis
The removal strips Congress and the public of independent verification for major weapons programs precisely as the Pentagon pushes a 2027 budget request, shifting oversight leverage toward the department's own claims. DOT&E almost certainly retains internal capacity to brief classified findings to cleared committee staff, so the loss falls on public accountability rather than congressional access. Restoration by October 31 is very unlikely absent legislative compulsion through the NDAA cycle, since the administration absorbed the missed August 26 response deadline without public reply. The staffing cuts may be driving the retreat from oversight more than any genuine new security calculus, and if reports stay restricted past the deadline Congress loses independent leverage to challenge Golden Dome and other program funding before the budget locks in. Moderate confidence reflects three independently sourced outlets converging on transition mechanics, though the AI-vulnerability rationale's weight against the staffing-driven argument remains contested.
