The Pentagon is preparing US bases to operate autonomously for 90 days in the event of a large-scale war, Fox News reports. The Fort program, developed at the initiative of Defense Secretary Pete Hegseth, includes connecting US military bases to independent power sources, securing fuel, water and munitions reserves, and equipping civilian manufacturing plants with equipment needed to rapidly transition to wartime production. The report notes that these measures were specifically designed for a potential large-scale conflict that could disrupt power grids and supply chains around the world.
