The Pentagon unveiled Fort America, a major defense initiative designed to ensure that every major US military base in the continental United States can operate independently for at least 90 days during a major war, even if civilian power grids, water supplies, fuel supplies and global supply chains are disrupted. The program includes portable nuclear reactors, large-scale battery storage, independent microgrids, and strategic reserves of munitions, fuel, critical minerals, electronics, and medical supplies. The initiative also calls for backup suppliers, hardened communications and preparations for the rapid conversion of civilian factories into wartime weapons production facilities. Pentagon spokesman Sean Parnell warned that dependence on civilian infrastructure poses an unacceptable security risk, declaring: "Power is combat now." The plan, announced by Defense Secretary Pete Hegseth in September, is designed to keep American forces operational during a protracted, potentially multi-front conflict. The implementation is still in its early stages, with costs and completion timelines still being assessed.
