The Pentagon is preparing a “doomsday” contingency plan for a global crisis in which the U.S. power grid collapses and supply chains are disrupted. Coverage says the plan, reportedly branded “FORTRESS” by Pentagon planners, focuses on enabling major military installations to operate independently for at least 90 days without relying on outside support.
According to the reports, the effort includes exploring ways for bases to generate and store power without municipal infrastructure, such as portable nuclear reactors, large battery systems, and independent microgrids. The coverage also points to preparations like stockpiling ammunition, fuel, critical minerals, electronics, spare parts, and medical supplies, as well as industrial stress tests and mobilization exercises.
Outlets describe these measures as intended to protect communications, logistics, weapons production, and command structures during prolonged outages or potential interference with satellite communications and GPS. While all sources draw on similar underlying details attributed to the Pentagon spokesperson Sean Parnell, their emphasis varies between the scenario’s scale (global war versus domestic grid failure) and the specific disruption pathways highlighted (power grid, supply chains, and infrastructure dependence).
