From Nuclear Reactors to Fuel Reserves U.S. Bases Prepare to Survive 90 Days Cut Off from Supply

The Pentagon’s FORTRESS America initiative seeks to make major US installations resilient to prolonged disruptions of electricity, fuel, water, communications and external supplies. A reported planning standard calls for at least 90 days of essential operations, supported by microgrids, battery storage, potential nuclear microreactors and strategic reserves of critical materials. The broader effort also addresses alternative production pathways, civilian-factory mobilization, hardened communications and protection of industrial control systems against cyber disruption. The 90-day objective describes a preparedness requirement rather than an achieved capability, while related Army microreactor projects and Air Force resilience programmes have separate implementation schedules.
