The Pentagon is preparing for a 90-day shutdown after Iran exposes the weaknesses of the US military.

The Pentagon is preparing its key domestic bases to continue operating for at least 90 days without outside support in the event of a major war that could cripple power grids, break supply chains and threaten infrastructure on American soil, according to Fox News. The new requirement is part of FORTRESS, a broader military effort to ensure that US forces can continue to fight even if the civilian systems they depend on are disrupted. According to the plan, every major military installation in the continental US is expected to maintain essential operations independently for at least three months, including electricity, water, fuel and communications. FORTRESS envisions mobile nuclear reactors, large-scale battery storage, and microgrids capable of completely disconnecting bases from the civilian grid, allowing them to continue operating during extended outages.

The strategy also requires strategic reserves of munitions, fuel, critical minerals, electronics, spare parts and medical supplies.

A separate component, the civilian production network, is designed to identify commercial plants that may switch to defense production during a crisis, with technical specifications, cyber security protections and conversion procedures set in advance rather than improvised in the middle of war. The main concern is the military's reliance on civilian power grids, which support everything from communications and logistics to weapons production. If they were disabled, the military command structures would collapse without the proper communications and energy needed to manufacture equipment. The push for self-sufficiency is not an abstract design. During the war with Iran, President Donald Trump openly threatened to destroy Iran's power plants and bridges, and US strikes hit thousands of points along Iran's power grid.
