New Pentagon ‘FORTRESS’ guidance would make major US bases self‑sufficient for 90 days
Documents reported by Fox News say a Pentagon strategy dubbed FORTRESS would require large US bases to operate for at least 90 days without outside support and ensure two domestic sources for critical supplies, signalling preparation for a prolonged high‑end conflict.
Major US military bases are being told to plan for operating in partial isolation for months, under new Pentagon guidance reported by Fox News.
According to the network, internal documents for a strategy known as FORTRESS state that large installations in the continental United States must be able to sustain essential operations for at least 90 days without external support. The same documents say critical military supplies should have at least two qualified domestic sources.
The 90‑day benchmark assumes that in a large‑scale conflict, bases inside the United States could face disrupted supply chains, cyberattacks or damage to key infrastructure and transport links. Being able to run core functions for three months without normal resupply would reduce the risk that a single failure or strike could halt operations.
Requiring multiple US‑based suppliers for crucial items is meant to guard against bottlenecks if one source is hit by attack, natural disaster or political restriction. Fox News reported that this applies to “critical military supplies,” though the documents it cited were not published in full and did not list specific products in the available material.
If implemented, the strategy would likely lead to larger on‑base stockpiles of fuel, food, medical stores and spare parts, and more resilient power, water and communications infrastructure on installations. It would also influence contracts with industry, pushing the defence sector to qualify and maintain backup sources for sensitive equipment and materials inside the United States.
The FORTRESS planning reflects lessons from recent conflicts in which ammunition stockpiles, production capacity and infrastructure resilience have become central constraints. By extending that thinking to domestic bases, the Pentagon is treating them as potential targets and pressure points in a major war rather than safe rear‑area depots.
Key signals to watch will be whether references to FORTRESS or to 90‑day base autonomy appear in public Pentagon budget documents, whether Congress asks for details on which supplies need two qualified sources, and how quickly funding and construction work at major installations begin to match the reported guidance.
