Since late August, refrigeration failures have affected commissaries at multiple U.S. military installations across at least 11 states, according to a detailed analysis published on Signal and Silence. The Defense Commissary Agency (DeCA) has acknowledged a “possible refrigeration disruption” at numerous commissaries, and Stars and Stripes and Military Times have independently reported on the incidents.
Confirmed failures occurred at Fort Huachuca, F.E. Warren Air Force Base, Fort Irwin, Columbus Air Force Base, Travis Air Force Base, Naval Air Station Lemoore, Port Hueneme, Dyess Air Force Base, and other installations between August 26–27. Additional unconfirmed reports emerged from Holloman Air Force Base, Robins Air Force Base, McConnell Air Force Base, Cannon Air Force Base, and Little Rock Air Force Base.
What distinguishes these failures is their simultaneity and nature. At Fort Huachuca, the Army’s official Facebook account confirmed that all commissary freezers entered defrost mode—which actively heats food rather than simply losing power. The installation clarified that “the power didn’t go out,” indicating the failures were not due to electrical outages.
DeCA operates approximately 235 commissaries worldwide through a centralized infrastructure. According to procurement documents from March 2026, DeCA manages refrigeration systems across roughly 182 locations using a Remote Monitoring and Control System (RMCS). DeCA’s own engineering specifications state that “defrost shall be controlled through the RMCS,” establishing that defrost cycles are remotely managed rather than locally controlled.
The RMCS includes refrigeration and HVAC monitoring at individual commissaries, with alarms monitored remotely 24/7 through a centralized master control system located in the continental United States, according to contract documentation. Individual commissary buildings also feature RSMS controls managing all refrigeration and HVAC systems, as described in contractor records for facilities like Robins Air Force Base.
While the author of the analysis emphasizes having “no evidence that the Defense Commissary Agency was hacked,” the combination of simultaneous failures across geographically dispersed bases, the networked nature of refrigeration controls, and the specific mechanism of defrost activation has raised questions about whether these failures could indicate a cyber incident rather than equipment malfunction. However, no official investigation findings or evidence of unauthorized access has been released.
Key facts
- Refrigeration failures confirmed at six military installations across 11 states on August 26–27
- DeCA manages approximately 235 commissaries worldwide using centralized Remote Monitoring and Control Systems
- Freezers entered defrost mode—actively heating food—rather than simply losing power
- DeCA’s engineering specifications specify that defrost is controlled through the RMCS
- Pentagon has acknowledged a “possible refrigeration disruption” at multiple commissaries
- No evidence of hacking has been confirmed, but the networked nature of controls raises technical questions
