The Pentagon is quietly reshaping Americas homeland defenses around a grim but increasingly plausible prospect: a major war that strikes the U.S. power grid and supply chains so hard that military bases must fight on while the civilian system goes dark.
According to Fox News, the effort is being organized under a sweeping initiative known as FORTRESS, a long-term plan to ensure U.S. forces can continue operating even if the nations critical infrastructure is crippled. Every major military installation in the continental United States would be required to sustain essential functions for 90 days with its own electricity, water, fuel, and communications, effectively turning bases into self-contained strongholds.
The concept reflects a stark recognition that in an era of cyber warfare, long-range missiles, and hostile great-power competition, the American homeland can no longer be treated as a safe rear area. The plan contemplates portable nuclear reactors, large-scale battery systems, and independent microgrids to keep bases functioning during extended blackouts.
Civilian factories would be pre-identified and prepared to shift rapidly into defense production, supported by stockpiles of ammunition, fuel, critical minerals, electronics, spare parts, and medical supplies. Critical military requirements would be backed by at least two qualified suppliers or production pathways, reducing the risk that the loss of a single plant or company could paralyze operations.
This redundancy-first approach stands in sharp contrast to decades of globalized, just-in-time supply chains that left the United States dangerously exposed during the COVID-19 pandemic and recent geopolitical shocks. Pentagon chief spokesperson Sean Parnell underscored the stakes in blunt terms, telling Fox News: 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. His warning reflects a conservative critique that Washington has been slow to confront the vulnerabilities created by overregulation, environmental extremism, and the offshoring of key industries to adversarial or unreliable nations.
For a Pentagon now planning for a high-end conflict with China, Russia, or both, the assumption that civilian grids and commercial networks will remain intact is no longer acceptable. The shift signals a fundamental change in war planning, away from distant counterinsurgencies and toward conflicts that could reach American soil and disable the very systems on which U.S. forces depend.
Power is combat now. Without electricity, you lose communications, water, logistics, assembly lines and just basic military command structures, Parnell told Fox News. The concern extends far beyond keeping the lights on at bases; a prolonged outage could cripple the industrial and digital backbone needed to sustain military operations, even if most of the fighting occurs overseas.
In effect, the Pentagon is acknowledging that the next major war will be as much about protecting factories, data links, and energy flows as about tanks and aircraft. One key pillar of the strategy is the Civil Reserve Manufacturing Network, a program to identify commercial plants that can be converted quickly to military production in a crisis.
Rather than improvising under fire, the Pentagon intends to pre-assess these facilities, define technical standards, install cybersecurity protections, and lock in contracts and conversion procedures well in advance. The initiative also envisions recurring industrial stress tests and mobilization drills to determine whether manufacturers can keep producing through cyberattacks, supply disruptions, or physical damage.
Stockpile targets for ammunition, fuel, and other essentials would be calibrated to how quickly they are consumed in a major conflict and how long industry would need to replenish them, Fox reported. The preparations extend into orbit, where adversaries are already probing American vulnerabilities.
Planners are working on ways to protect satellite links and preserve military communications and navigation if GPS is jammed or other space-based systems are degraded or destroyed. Secretary of War Pete Hegseth formally established FORTRESS America in a September 30 memorandum that described the objective as a homeland that cannot be starved out, shut down, or cut off. The directive organizes the effort around five priorities: energy independence, stronger supply chains, strategic reserves, protection of military installations, and resilience in space and the electromagnetic spectrum.
Hegseths order instructed the Pentagons acquisition and sustainment leadership to stand up a dedicated program office within 30 days. That office would begin with a small core team and expand to full operating capability within months, with the memorandum explicitly demanding results in weeks rather than years.
An October 6 implementation directive subsequently named Richard Matt OMalley as interim director, according to DefenseScoop, which obtained the document. A two-star military adviser will support him, while eight senior Pentagon officials have been told to nominate representatives to coordinate with the new office.
Those officials span personnel, industrial policy, installation management, technology, and financial oversight, underscoring how many corners of the department must be aligned to harden the homeland. The public founding memo lays out the programs structure and broad priorities, while the more detailed 90-day self-sufficiency requirement emerged later in Foxs reporting.
You don't want to be making these decisions in the middle of a global multi-front conflict. We have to have a plan, Parnell said. The Daily Mail has contacted the Pentagon for comment.
For conservatives who have long warned about the dangers of hollowing out domestic industry and overreliance on fragile global systems, FORTRESS America represents a long-overdue course correction. The question now is whether the Pentagon and political leaders will move fast enoughand cut through bureaucratic inertia and ideological resistanceto build a homeland that cannot be starved out, shut down, or cut off before Americas adversaries test these preparations in the real world.
