Over the past week, I've seen quite a few news stories and social media posts discussing the Pentagon's FORTRESS America initiative.
One particular number keeps coming up: 90 days.
According to recent reporting, the military is working toward making major installations more independent of civilian infrastructure, including electricity, water, fuel, communications, and critical supplies.
Naturally, that's sparked plenty of discussion online about what the military might be preparing for and whether ordinary Americans should be doing the same.
I don't want to get caught up in predicting what might or might not happen. That's never really been the purpose of The Ready Dad Project.
But the discussion did get me thinking about something practical.
What does 90 days of food actually look like for an ordinary family?
Recently, while working on my family's deep pantry, I started calculating how much food we'd need to support five people for three months.
I was genuinely surprised by the numbers.
First, a Little Perspective on the News
FORTRESS America is a real military initiative focused on improving the resilience of U.S. installations.
Announced in late September, the initiative addresses several areas, including independent energy production, supply chain resilience, strategic reserves, and protecting installations against physical and cyber threats.
Recent reporting has described goals for military installations to sustain essential operations for up to 90 days without outside support. Pentagon officials have also discussed 90-day reserves of certain critical military supplies.
It's worth noting that the original publicly released initiative memo did not itself specify a blanket 90-day requirement. Some of the more specific details have emerged through subsequent reporting and official comments.
More importantly, none of this means civilians have been instructed to store 90 days of food, and it certainly doesn't establish that a major emergency is about to happen.
Military installations have very different responsibilities and requirements than ordinary households.
Still, I think there's a valuable lesson in the underlying idea.
If we know that power grids, transportation systems, communications networks, and supply chains can be disrupted, it makes sense to understand how dependent our own households are on those systems.
And food is a good place to start.
Ninety Days Is a Lot Longer Than It Sounds
When people talk about having three months of food, I think it's easy to picture a stocked pantry, some extra rice and beans, and a few cases of canned goods.
But consider a family of five.
Five people eating three meals per day means 15 individual meals every day.
Over 90 days, that's 1,350 individual meals.
And that doesn't account for snacks, growing teenagers, different appetites, dietary restrictions, or food that gets wasted.
For another perspective, if we use an illustrative average of 2,000 calories per person per day, our family would need approximately 900,000 calories over three months.
Of course, individual calorie needs vary depending on age, size, activity, and other factors. This is just a starting point for understanding the scale, not a nutritional recommendation.
Now imagine trying to assemble that much food from scratch.
Suddenly, three months doesn't sound quite so simple.
The Canned Vegetable Calculation That Surprised Me
This was one of the more eye-opening parts of my own pantry planning.
I started looking at canned vegetables.
They're relatively inexpensive, easy to store, familiar to most families, and useful for making regular meals.
Let's assume each person in our family eats just one cup of canned vegetables per day.
That's five cups for the household.
Over 90 days, we would need 450 cups of vegetables.
Using an example of a standard can containing approximately 3.5 half-cup servings, that works out to roughly 260 cans of vegetables.
That's nearly eleven full cases of 24 cans.
And remember, we're talking about only one cup of vegetables per person per day.
Increase that to two cups, and we're looking at approximately 515 cans.
At 2½ cups, it's around 643 cans.
Actual quantities would vary depending on the vegetables, can sizes, and usable portions after draining.
But the point is clear.
That's a tremendous amount of canned food, and we haven't even started calculating everything else we'd need.

What About Rice, Oatmeal, and Other Staples?
Canned goods are only one part of the equation.
Dry foods can provide a lot of nutrition and energy while taking up less space, and they're often more affordable when purchased in larger quantities.
But those numbers add up quickly, too.
Suppose everyone in our family ate half a cup of dry oatmeal for breakfast every morning.
For 90 days, we'd need roughly 40 pounds of oats.
Or imagine everyone ate one cup of cooked white rice each day as part of lunch or dinner.
That would require approximately 60–65 pounds of dry rice over the same period.
Even something as simple as peanut butter adds up. At two tablespoons per person per day, we'd need roughly 32 one-pound jars.
Obviously, I'm not suggesting my family eat oatmeal, rice, and peanut butter every single day for three months.
These are separate examples meant to illustrate how quickly normal portions become substantial quantities when multiplied across an entire household.
And they don't come close to representing a complete, balanced diet.
We'd still need to account for protein, fruit, vegetables, fats, dairy or suitable alternatives, other grains, and the ingredients that turn basic supplies into actual meals.
The Difference Between Having Food and Having Meals
This is something I've been thinking about more as we've worked on building our deep pantry.
Having 50 pounds of rice is great.
But what are we going to eat with it?
What meals can we realistically prepare using the ingredients we have?
And could we still make those meals if the power was out?
My family has been doing more cooking at home lately. We've been making homemade pizza, baking treats, and buying some ingredients in larger quantities when the price makes sense.
For example, we discovered that our local butcher offers a good price on hamburger when we buy ten pounds at a time.
Those are the kinds of purchases that make sense for us because they're foods we already eat.
But a freezer full of hamburger is only part of a preparedness plan. During a prolonged power outage, we'd need a reliable way to keep that food frozen or a plan to use it safely before it spoils.
Likewise, dried beans and rice are useful only if we have enough safe water and a way to cook them.
Food storage isn't just about how much food you own. It's about whether you can turn that food into meals under the conditions you're preparing for.
There's also the question of variety.
I know my family wouldn't be particularly excited about eating the same few meals for three months.
And honestly, neither would I.
A practical pantry should contain ingredients that allow us to make different meals, maintain reasonable nutrition, and keep some sense of normalcy if things aren't going according to plan.
That might seem like a minor consideration, but I think it matters quite a bit, especially when you have kids.
I'm Not Suggesting Everyone Needs 90 Days Immediately
I think it's important to keep some perspective here.
The American Red Cross recommends keeping a two-week supply of nonperishable, easy-to-prepare food for use at home.
Here in Washington, our state's Emergency Management Division also encourages households to be two weeks ready.
That's a much more approachable starting point than trying to acquire three months of supplies all at once.
And for many families, even getting to two weeks would represent a meaningful improvement.
Personally, I like the idea of building a deeper pantry gradually.
Start with foods your family already eats.
Build enough inventory to cover a few extra meals.
Then work toward a week, two weeks, a month, or whatever longer-term goal makes sense for your household.
As I've discussed before, I'd eventually like our pantry to be something that works as part of our everyday life rather than a collection of emergency food sitting untouched in the garage.
That means tracking what we have, using the oldest products first, replacing what we consume, and maintaining reasonable minimum quantities.
It also means buying more of certain products when prices are good, rather than waiting until we're completely out.
The goal is to have a household inventory that makes us more resilient without creating unnecessary waste or expense.
And as we've been discovering, that kind of pantry can help with more than just emergencies.
It can make everyday meal planning easier, reduce unnecessary grocery trips, and give us a little more flexibility when the family budget gets tight.
Here's an Exercise Worth Trying
Before buying several hundred cans of vegetables or a hundred pounds of rice, I'd suggest starting with something simpler.
Write down what your family actually eats for one week.
Not what you imagine you'd eat during an emergency. What you really eat.
Include breakfast, lunch, dinner, snacks, drinks, and the ingredients needed to prepare everything.
Then look at those meals and ask yourself a few questions.
Which meals could be made using shelf-stable ingredients?
Which depend on refrigeration or freezing?
Which require a lot of water or cooking fuel?
Which could be adapted to use canned, dried, or other shelf-stable ingredients?
And which ingredients do you already buy regularly that would make sense to keep a little extra of?
Finally, multiply those weekly quantities by approximately thirteen weeks.
That won't produce a perfect emergency food plan, but it will give you a much better understanding of what 90 days means for your particular household.
And I suspect some of the numbers will surprise you as much as they surprised me.
You may even discover that getting started is easier than you expected because many of the foods you need are already part of your normal grocery shopping.
My Biggest Takeaway
When I first started thinking about food preparedness, I tended to think in terms of individual purchases.
A few cases of canned food here. An extra bag of rice there. Some frozen meat when it was on sale.
There's nothing wrong with that approach. In fact, it's how I think many families should begin.
But doing the math for a family of five has changed the way I look at longer-term food storage.
Three months is a lot of breakfasts, lunches, and dinners.
It's a lot of calories, ingredients, storage space, planning, and meal preparation.
And it's not something most households can realistically build overnight.
Regardless of what happens with the military's FORTRESS America initiative, I think there's value in understanding these numbers.
Not because we should be frightened about what might happen tomorrow.
But because understanding what our households actually need is the first step toward becoming more prepared.
And that's really what The Ready Dad Project is about.
Practical resilience for everyday families.
A Question for You
Have you ever calculated how much food your household would need for 30, 60, or 90 days?
Was the amount more than you expected?
I'd be interested in hearing how other families approach building a deeper pantry, especially those who have found practical ways to do it without spending a fortune.
