Bases preparing for 90 days without power or resources

The Pentagon's FORTRESS initiative requires every major U.S. military base to sustain operations for 90 days without civilian power or supply chains.

The Pentagon is preparing a 'doomsday plan' called FORTRESS to keep US military bases operational for at least 90 days without civilian power, water or fuel

Under the new plan, U.S. military bases must operate independently for 90 days amid global supply chain and security threats.

The initiative would allow military bases to continue functioning without relying on civilian electricity networks, international supply chains or outside deliveries of essential resources, including fuel and water.

The Pentagon is preparing US military bases to operate independently for at least 90 days during a major war, securing essential services and supplies against disruptions to civilian infrastructure and global supply chains, according to a report.

Pentagon Prepares major U.S. bases for 90 days without outside power, water, fuel, communications, or supplies under FORTRESS America.

Under FORTRESS America, announced by US Secretary of War Pete Hegseth on 30 September 2026, every major military installation in the United States is intended to generate power independently of the civilian grid.

The Pentagon is working on a plan to ensure that major military installations across the continental US can continue essential operations for at least 90 days without relying on outside support.

The plan calls for independent power systems, portable nuclear reactors, stockpiles of fuel and ammunition, backup communications and preparations to convert civilian factories to wartime production. The Pentagon is planning for a scenario in which the infrastructure Americans depend on every day may no longer be available. Pentagon chief spokesperson Sean Parnell told Fox News that the military can no longer assume American bases will have reliable access to the civilian systems surrounding them.
