For years, the official advice to American families has been to keep three days of supplies on hand. Now the Pentagon is planning for its own bases to survive 90 days without any outside help at all.
The effort is called FORTRESS, and it’s one of the clearest signals yet that the people responsible for national defense are taking long infrastructure outages seriously. It’s not a warning that an emergency is coming. But it does raise a fair question for every household: if the military is planning for 90 days, how long could you last?
What the FORTRESS Plan Is
Defense Secretary Pete Hegseth unveiled FORTRESS in his State of the Force address at Marine Corps Base Quantico on September 30. The name stands for Federal Operations for Resilience, Troop Resources, Energy, Supply and Survivability.
According to International Business Times, which summarized reporting by Fox News Digital, internal Pentagon documents describe a requirement for major installations in the continental U.S. to sustain essential operations on their own for at least 90 days. That covers electricity, water, fuel, and communications, not just power.
The plan also calls for strategic reserves of munitions, fuel, critical minerals, electronics, spare parts, and medical supplies. For the most critical items, it wants at least two separate supply or production sources, so losing one factory doesn’t stop everything.
Why the Military Is Doing This
Pentagon chief spokesperson Sean Parnell put it bluntly, calling reliance on civilian infrastructure an “intolerable risk.” He told Fox News Digital that without electricity, a base loses communications, water, logistics, and its command structure.
The concern is simple. Most U.S. bases run on the same civilian power grid, water systems, and supply chains as the towns around them, and a major conflict, cyberattack, or disaster could knock those systems out.
Potential solutions include microgrids, battery storage, solar, geothermal, and natural gas. Separately, the Army announced in August up to $2.2 billion in agreements to build nuclear microreactors at five bases, including Fort Bragg and Fort Hood.
What It Isn’t
It’s important to keep this in perspective. FORTRESS is a long-term resilience program, not a response to a specific threat or a sign that something is about to happen.
There’s no public budget or completion date yet, and a senior defense official said the Pentagon is still assessing energy needs across roughly 500 installations. The 90-day standard is a goal, not proof that bases can already do it.
From 14 Days to 90 Days
What stands out is how much the target has grown. In 2017, an Army directive on installation energy and water security set a goal of keeping critical missions running for a minimum of 14 days.
The new target is more than six times longer. When military planners extend their own timeline that much, it’s a good moment for families to look at theirs.
What This Means for Your Household
FEMA’s basic disaster supplies kit is built around at least several days of food and water. That’s a solid starting point, but it assumes help arrives quickly, and the military clearly isn’t counting on that for itself.
You don’t need to match a military base. But building your plan in stages makes a long outage far less frightening.
Stage One: Three Days
Cover the basics first: water, non-perishable food, medications, flashlights, a first aid kit, and a hand-crank emergency radio for news when cell service drops. Most households can get here in a single weekend.
Stage Two: Two Weeks
The CDC recommends storing at least 1 gallon of water per person per day, and a 2-week supply if possible. For a family of four, that’s 56 gallons, so stackable water storage containers make the job much easier.
Build your pantry to two weeks of meals your family actually eats, and keep a 30-day supply of prescription medications if your doctor and insurance allow it. Add a way to cook without power, like a camp stove with extra fuel stored safely outdoors.
Stage Three: 30 to 90 Days
This is where independence really starts, and where the military’s priorities offer a useful checklist. Power, water, fuel, and communications are exactly the categories to plan for.
For power, a portable power station with solar panels can keep phones, lights, and small appliances running without fuel deliveries. For water, think beyond storage to a renewable source, like a rain catchment system paired with a quality gravity filter.
For food, a deep pantry of rice, beans, oats, and canned goods, plus a long-shelf-life emergency food supply, stretches your runway. A garden, seeds, and food preservation skills will carry you further than any single purchase.
Take It One Step at a Time
A 90-day plan can feel overwhelming, so don’t try to build it all at once. Start with three days, then two weeks, then add a little each month.
The goal isn’t to prepare for doomsday. It’s to make sure that when the power, water, or supply chain goes down, your family has time to wait it out calmly.
The Bottom Line
The Pentagon isn’t predicting a disaster. It’s planning for the possibility that civilian systems could fail for weeks or months, and deciding its bases shouldn’t depend on them.
That’s a reasonable lesson for any household. If the most powerful military in the world is planning to stand on its own for 90 days, three days of supplies is a starting line, not a finish line.
