The Pentagon is preparing major U.S. military bases to operate for at least 90 days without civilian power, fuel or supply lines under an initiative called FORTRESS. Defense Secretary Pete Hegseth announced the broader plan on September 30, 2026. Fox News reported the 90-day target on October 25 after reviewing planning documents. The effort includes portable nuclear reactors, large battery systems, microgrids and stockpiles of critical minerals. These steps add a defense-related layer to demand for uranium, copper and certain battery metals that Canadian mining companies already produce.
FORTRESS stands for Federal Operations for Resilience, Troop Resources, Energy, Supply, and Survivability. Hegseth described it as an insurance policy so that bases can keep running if civilian grids or supply chains fail. Pentagon chief spokesperson Sean Parnell told 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." He added, "Power is combat now. Without electricity, you lose communications, water, logistics, assembly lines and just basic military command structures." The reported 90-day standard covers electricity, water, fuel and communications for major continental installations. A microgrid is a local power network that can disconnect from the wider grid and keep critical loads running on its own sources.
Reports say FORTRESS calls for strategic reserves of munitions, fuel, critical minerals, electronics, spare parts and medical supplies. Critical minerals are metals and materials that governments treat as essential for defense, energy or technology and that face supply risks. Portable nuclear reactors need uranium fuel. Large battery installations need materials such as lithium, nickel or graphite depending on the chemistry. Copper is used in wiring, microgrids and power equipment. These needs do not replace commercial demand from data centers or electric vehicles, but they create an additional buyer that can stockpile material. For Canadian mining companies that produce uranium or copper, the plan is one more source of potential offtake. An offtake is a long-term agreement to buy a set volume of metal at agreed terms.
The Army has already awarded contracts under its Janus program for microreactors at several bases, with goals of early deployments by 2028. Companies such as Radiant Industries have been selected for specific sites. These reactors are designed to run for years without refueling and to operate in island mode, which means fully separate from the civilian grid. Battery storage complements nuclear or diesel backup by providing rapid response. Both technologies require metals that mining companies extract and process. The FORTRESS timeline of 90 days of independence is longer than many existing base microgrids, so it implies larger reserves of fuel and critical minerals. Investors can track whether the Pentagon publishes specific volume targets for those stockpiles.
Cameco (TSX: CCO, NYSE: CCJ) produces uranium in Canada and has long-term contracts with utilities and, in some cases, government-related buyers. Higher defense-related uranium demand would support the price if new reactors are built and fueled. One real risk is that reactor deployment timelines slip, which has happened with advanced nuclear projects in the past. Teck Resources (TSX: TECK.B, NYSE: TECK) produces copper in Canada and South America. Copper is used in the power systems that microgrids and bases require. One real risk is that higher energy costs or permitting delays at its own operations raise its all-in sustaining costs. All-in sustaining costs, or AISC, measure the full cost to produce and sell a unit of metal after sustaining capital. Neither company has issued guidance specifically tied to FORTRESS, so any benefit remains prospective.
Some analysts link heightened focus on infrastructure resilience to longer cycles of institutional stress and rebuilding. The FORTRESS documents emphasize the risk of cyber attacks, sabotage or supply-chain breaks during a multi-front conflict. Parnell told Fox News, "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." Stockpiling critical minerals is one concrete response. For mining investors the practical question is whether government purchases or long-term contracts materialize at volumes large enough to move prices or company revenues. Past strategic stockpile programs have sometimes been smaller than initial announcements. Company results and any new federal procurement notices will show the actual scale.
Watch for any further Pentagon or Department of Defense releases that quantify stockpile targets or reactor deployment dates. Several Canadian producers report third-quarter results in early November 2026. Those updates will show current production and costs for uranium and copper. Any new federal critical minerals funding or changes to export rules will also affect the outlook. Inventory data for copper and uranium will show whether physical markets are tightening independently of the defense plans.

Reports say FORTRESS includes stockpiles of critical minerals along with fuel, electronics and spare parts. It also calls for portable nuclear reactors and battery storage, which use uranium and battery metals. These needs sit alongside existing commercial demand.
Watch for further Pentagon details on stockpile sizes or reactor timelines. Company results in November will update production costs for uranium and copper producers. Any new federal critical minerals funding or export rules will also matter.
