Biggest Military Bases in the U.S.


The United States has the strongest military in the world, by a long shot. It would make sense that the U.S. would have a lot of military bases to keep up with all the military functions necessary to maintain order. But how many American military bases are there and which is the biggest?

It’s difficult to be sure of an exact number since bases are continually opening and closing depending on the current needs of the military but it’s safe to say that the United States is managing a huge operation in terms of military bases.

From the number of military bases in the United States as well as all the U.S. military installations abroad, we’ll check out the 50 biggest military bases throughout the 50 states and we’ll see where the majority of U.S. military bases are worldwide.

How Many Military Bases Does the U.S. Have?

During the wars in the middle east, several hundred U.S. military bases were erected, many of which have recently been closed in Iraq and Afghanistan. Still, the American military bases in foreign countries have reached staggering numbers.

U.S. military bases worldwide seem to be most prevalent in a few specific countries including Italy, Japan, Honduras, Burkina Faso, Iraq, Thailand, and the Philippines. But don’t be fooled, American military presence can be felt in all corners of the world.

Since the United States is such a massive military power on the world’s stage, American military bases are installed all around the world. According to Politico Magazine, the U.S. holds up to 800 military bases in over 70 countries.

How Many Military Bases Are in the U.S.?

Let’s start with just the military bases that you can find within the country itself.

Between all 50 states, the District of Columbia, and the U.S. territories of Guam and Puerto Rico, the U.S. Department of Defense oversees more than 420 military installations. That’s not including all of the U.S. military bases located overseas.

These hundreds of military bases are used for various different missions including training, deployment, weapon maintenance and testing, research, and education. Considering all that goes on at a military base, it makes sense that these installations would take up quite a lot of space and end up being rather large.

What is the Largest Military Base in the United States?

As previously mentioned, the activities that take place on a military base require a lot of space. That means many of the bases in the U.S. are huge and expansive, often holding many active-duty soldiers.

These bases are always changing but to give you an idea of the largest military base in the country, here’s a list of the biggest 50 out of over 420 military bases in the United States according to physical size.

50. Kings Bay Navy Submarine Base – Georgia; 16,616 acres; 2,717 active duty service members

As you can see, the biggest military base in the U.S. exceeds the others in acreage by over two million acres. Operated by the Army, the extensive area only has about 338 active duty service members on the base. It’s the country’s largest open firing range and it was also utilized by NASA as a landing site for the Space Shuttle operation. Due to its wide-open spaces, it makes sense the White Sands is a missile base and is also exceptional for satellite tests.

How Many U.S. Military Bases Are There in the World?

To give you an idea of how extensive the number of U.S. military bases there are in the world, let’s compare it to the numbers that other countries maintain.

With nearly 800 American military bases sprinkled all over the planet, places like Britain, France, and Russia – all relatively large and powerful countries – have about 30 foreign military bases, combined.

So, why does the U.S. military insist on having so many?

It could be estimated in 2014 that maintaining military bases and troops abroad could cost up to $100 billion per year with those accounts going up to $200 billion in active war zones. These costs have sparked the debate on whether these foreign U.S. military bases are necessary.

The answers continue to remain unclear but these debates are worth thinking about, especially after seeing the numbers.

What are some of the U.S. Military Bases Around the World?

Most of the U.S. military bases around the world are going to be smaller than those at home, although some foreign bases have become “Little Americas”. Of the countries that hold the most U.S. military bases abroad, how many are there in each?


In Italy, the presence of American military bases has remained relatively constant, even though hundreds of other bases elsewhere in Europe have closed since the 1990s. A new U.S. military base has even recently been built in Sicily to expand operations focused on Africa.


In order to surround China and the Soviet Union during the Cold War, the U.S. military established hundreds of bases in Japan and throughout the Pacific region. Even amongst protests in Okinawa, there are still over 30 American military bases in Japan.


Since 1982, a temporary base has existed in Honduras. It’s a loophole in Honduras’ constitution prohibiting permanent foreign troop presence.

Burkina Faso

Smaller U.S. military bases are starting to pop up all over the globe and they’re being called cooperative security locations. Operating as a base by hosting special operations forces, drones, and surveillance flights, at least 11 of these kinds of bases have emerged and remained in Africa.


At the height of American occupation of Iraq during the recent wars, 505 U.S. military bases were functioning in the country. After the 2011 withdrawal, the U.S. wanted to keep 58 “enduring” bases in Iraq but Parliament vetoed the motion. Since 2014, there are only five U.S. military installations in the country.


Not technically considered a U.S. military base, the Pentagon rents space at UTapao Naval Air Base from a contractor. It served as a major hub during the Iraq and Afghanistan wars.


In the ‘90s, there was a huge eviction campaign to get U.S. military bases out of the Philippines. Yet, since 2002, at least 600 U.S. troops were deployed there to help Filipino combat insurgents with 6,000 U.S. troops operating temporarily as military exercises.


In conclusion, it’s pretty overwhelming to think about all the cogs working together in this well-oiled machine we call the U.S. military. With massive military bases all around the country and countless U.S. bases functioning all over the globe, the Department of Defense is a mega-power that you won’t want to mess with.
