The Pentagon is preparing for the possibility of making military bases autonomous for 90 days in the event of a major conflict - Fox News The US Department of Defense, as part of the Fortress Initiative, is developing new standards for all major military installations in the country: each base must be able to support key operations, including access to electricity, water, fuel and communications, regardless of external supplies, for at least 90 days. Fox News reports this, citing documents investigated by journalists. "We don't want to rely on conventional urban civilian infrastructure to provide national defense. We just can't do it. It's an unacceptable risk," Pentagon spokesman Sean Parnell told Fox News Digital. According to him, electricity has become the basis of modern military activity: "Without electricity, we lose communication, water supply, logistics, production lines and essential elements of the military command." Fortress concept includes the use of mobile nuclear reactors, large-scale battery energy storage systems and microgrids that will separate military installations from civilian power grids and continue to operate in the event of prolonged outages. In addition to energy, the program covers strategic stockpiles of ammunition, fuel, critical minerals, electronic components, spare parts and medical supplies, as well as alternative supply chains and the ability to repurpose civilian businesses for defense needs in times of crisis. As Fox News notes, the new doctrine reflects a shift in the Pentagon's approach to national defense: "A lot of our ideas about protecting the nation were based on the old-fashioned assumption that two oceans would protect us. President Trump understands that this world has collapsed," Parnell added, citing the Gold Dome initiatives and the increasing focus on the Western Hemisphere, Greenland and Panama.
