Pentagon Implements 'FORTRESS' Plan for Base Independence
The Department of Defense is preparing for a scenario in which the American power grid collapses, forcing military installations to operate independently for three months without outside support. Pentagon planners have branded this initiative FORTRESS, aiming to make major bases across the continental United States capable of functioning independently for at least 90 days, according to documents obtained by Fox News.
DoD spokesperson Sean Parnell emphasized the strategic necessity of the plan, stating, "We don't want to rely on standard civilian municipal infrastructure to run our national defense. We just simply can't. It's an intolerable risk." The initiative reflects a broader shift in military doctrine, with officials noting that the loss of electricity could cripple communications, logistics, weapons production, and military command structures.
Portable Power and Industrial Mobilization
To achieve this level of autonomy, the Pentagon is exploring a combination of portable nuclear reactors, massive battery installations, and independent microgrids that would allow bases to disconnect from civilian power systems during prolonged blackouts. Demonstrating the feasibility of such technology, U.S. Air Force airmen and civilian contractors prepared a containerized nuclear power reactor for airlift aboard a C-17 Globemaster III at March Air Reserve Base in California on Feb. 13, 2026.
Beyond energy generation, the FORTRESS plan calls for extensive logistical preparations. Officials have outlined requirements for stockpiling ammunition, fuel, critical minerals, electronics, spare parts, and medical supplies. Additionally, the Pentagon plans to prepare civilian factories to rapidly transition into wartime production. To ensure readiness, the department intends to conduct recurring industrial stress tests and mobilization exercises.
Threats from Hackers and Saboteurs
The urgency of these preparations stems from ongoing threats to America's power grid from both foreign adversaries and domestic saboteurs. In February 2024, the NSA and other federal agencies warned that Chinese state-sponsored hackers linked to Volt Typhoon had compromised critical U.S. infrastructure networks, including energy, water, transportation, and communications systems.
Domestic threats also pose significant risks. In December 2022, gunmen attacked two electrical substations in North Carolina, plunging roughly 45,000 customers into darkness and leaving some without power for five days. These incidents underscore the vulnerability of critical infrastructure to physical and cyber attacks.
Shifting Strategic Assumptions
Parnell highlighted a fundamental change in how the military views homeland defense. "I realized that a lot of the way we think about homeland defense was built around the antiquated assumption that two oceans would protect us," he said. He noted that President Trump understands this world is gone, paving the way for new thinking focused on the Golden Dome, a renewed focus on the Western Hemisphere, Greenland, and Panama.
The official added that the next conflict will likely be fought on multiple fronts. "Look at the geopolitics behind any major war. When that happens, global supply chains will break," he said. "You don't want to be making these decisions in the middle of a global multi-front conflict. We have to have a plan." As part of these preparations, the Pentagon is also implementing measures to protect military communications and navigation systems from satellite disruptions and GPS jamming.
