The United States, in its early years, was a country that did not want to intervene in armed conflicts outside its borders. The country’s attitude towards having a global role changed completely after the two world wars which made it a nation that proactively sought to keep an eye on global threats and also promote American ideals across the world.

While military and intelligence capabilities of the United States were greatly stretched in the two World Wars and later during the Cold War, in modern times it has had to grapple with the challenges emanating from countries like Russia, China, North Korea, and Iran. Therefore, in order to have a logistical edge over its foes, the US maintains military bases around the world, which gives it the capability to strike enemy targets anywhere in the world. A majority of these bases are equipped with modern military equipment and airfields.

According to a report, the U.S. had about 750 military bases across 80 countries in the world and had deployed 173,000 troops in 159 different countries as of July 2021. Japan has the highest number of overseas military bases of the U.S. with 120 bases, followed by Germany and South Korea at second and third, with 119 and 73 bases respectively. These numbers are testament to America’s military and economic strength to be able to have such significant military presence outside its borders.

United States Military Strength

The United States has the most powerful military in the world. The country accounts for nearly 40% of all defense spending worldwide, which is triple the amount that China spends, and more than the combined amount that the next ten highest spenders incur on defense expenditure.

The U.S. is also home to some of the largest defense contractors in the world. Most notably four of the top five defense contractors in the world, which include Lockheed Martin Corporation (NYSE:LMT), RTX Corporation (NYSE:RTX), General Dynamics Corporation (NYSE:GD), and The Boeing Company (NYSE:BA).

U.S. Military Bases in the Middle East

Though an exact count is not known, the U.S. has several military bases in the Middle East that deploy more than 30,000 U.S. troops according to the Department of Defense. The most notable of all is the Al-Udeid Air Base in Qatar, situated west of Doha. It is the largest military installation of the United States in the Middle East and critical for operations in the region. The air base hosts an estimated 11,000 troops and is well equipped with fighter jets. The US Air Force deployed five 5th Generation F-22 Raptors developed by Lockheed Martin Corporation (NYSE:LMT) to the air base in 2020.

The Al-Udeid Air Base is also used by the US to aid Qatar in bolstering its defense capabilities. The Boeing Company (NYSE:BA) in 2020 got a $657.2 million deal from the Qataris to provide sparing and logistics support for the Qatari air force’s fleet of F-15 aircraft. Moreover, formerly Raytheon Technologies Corporation (NYSE:RTX), now RTX Corporation (NYSE:RTX) received a $77 million contract in the same year to upgrade Qatar’s Air Operations Center by 2025. Work on both contracts was and is being carried out at the Al-Udeid Air Base.

U.S. Military Bases in Japan and South Korea

The Americans have maintained a military presence in Japan since the conclusion of the second World War in 1945 and in South Korea since the Korean War starting 1950. More than half of all American troops deployed overseas are stationed in these two countries. Camp Humphreys, located 40 miles south of Seoul in South Korea, is the largest overseas U.S. military base in the world.

The base is equipped with Terminal High-Altitude Area Defense, or THAAD, an anti-ballistic missile defense system developed for South Korea by Lockheed Martin Corporation (NYSE:LMT) in response to regular missile threats from North Korea.

U.S. Military Presence in Europe

There are eight U.S. Army garrisons located across Europe which are home to at least 60,000 troops. Germany has the highest number of American bases and troops among European countries. The most notable U.S. military base in Europe is the Ramstein Air Base in Germany, which is critical to the American Air Force’s European operations.
