Pentagon unveils 90-day self-sufficiency plan for U.S. bases amid war risks

The Pentagon's FORTRESS initiative mandates that all major military installations on the continental United States be capable of sustaining essential operations for at least 90 days without relying on civilian utilities. To achieve this, the service will deploy portable nuclear reactors, large-scale battery banks and microgrids that can isolate bases from the national power grid. The program also establishes strategic stockpiles of ammunition, fuel, critical minerals, electronics and medical supplies to offset potential disruptions in global supply chains.

A parallel effort will identify commercial manufacturers that can be rapidly converted to defense production, with pre-arranged contracts, cybersecurity safeguards and technical specifications. Regular industrial stress tests and mobilization drills will assess the resilience of these supply pathways. The overall goal is to ensure that U.S. forces can continue fighting even if a large-scale conflict cripples civilian infrastructure.
