A 90 day survival kit is a long term supply for three months: long shelf life food (often in buckets), large water storage plus a way to filter more, solar or generator power, medical supplies and skills like gardening, fishing or hunting. Official household guidance is at least 72 hours; the 90 day figure comes from reported Pentagon planning for military bases.
In October 2026, news reports said the Pentagon is planning for major U.S. military bases to keep running for 90 days without outside support. That is a standard for military bases, not official advice for households. The official household guidance is still at least 72 hours, with two weeks recommended for sheltering at home.
Still, many families ask a fair question: if the military plans for 90 days, should we prepare for longer too? If you have already covered 72 hours and two weeks, a 90 day plan is the next step toward real independence.
1. Food for three months
The simplest path is a 3 month emergency food supply per person, or a 1 year supply for the most protection. Many families blend store bought freeze dried food with a home pantry built from bulk rice and beans sealed in mylar bags and food grade buckets.
To build your own supply over time, consider a home freeze dryer or a pressure canner. See all food storage tools.
2. Water you can renew
Storing 90 days of water for a family takes a lot of space, so combine storage with renewable sources. A 55 gallon barrel kit or a large storage tank gives you a deep reserve. Add a countertop gravity filter and rain barrels where local rules allow.
3. Power without the grid
For long outages, solar is the key because it needs no fuel deliveries. A large home backup power station paired with solar panels can keep your fridge, lights and devices running. A dual fuel generator with stored propane handles big loads. Have a licensed electrician install a transfer switch.
4. Grow and gather food
- Start a garden with heirloom survival seeds and raised beds
- Learn to fish with a rod and tackle setup (see fishing gear)
- Hunt legally and process your own meat (see hunting gear)
5. Health and knowledge
Long emergencies make medical skills and good books priceless. Read The Ultimate Survival Medicine Guide and Where There Is No Doctor, and take a first aid class.
6. Security and community
Protect what you have stored with a quality safe, solar security lights and good relationships with neighbors. In long emergencies, community is one of your greatest resources.
Common questions
Did the government tell people to store 90 days of supplies?
No. The 90 day figure comes from reported Pentagon planning for military bases. Official household guidance in the U.S. is at least 3 days, with 2 weeks suggested for sheltering at home.
How much does a 90 day food supply cost?
It varies widely by brand and how much you build yourself. Bulk staples you seal at home cost far less per calorie than ready made freeze dried meals.
