Earlier this year, the Biden Administration submitted a fiscal 2024 defense budget for congressional approval. At $842 billion, the proposal marks a $26 billion increase from the previous year’s budget, and a $100 billion increase from fiscal 2022. Against a backdrop of China’s rapid militarization, the latest budget will fund the Defense Department’s largest-ever investments in readiness, procurement, and research and development, as noted in comments by Secretary of Defense Lloyd Austin. (Here is a look at China’s 8 biggest weapons manufacturers, and what they build.)
These historic levels of investment will be a boon for defense contractors. Each year, the Pentagon relies on private sector contractors for everything from base maintenance and construction to weapons development and manufacturing, spending hundreds of billions of dollars in the process.
Partially as a result, America’s defense industry by far the largest of any country. As of 2021, 40 of the world’s 100 largest weapons manufacturers were headquartered in the United States.
Using 2021 arms sales data from the Stockholm International Peace Research Institute Arms Industry Database, 24/7 Wall St. identified the largest American weapons manufacturers, as measured by arms and military services sales. Each of the 36 companies on this list reported at least $1 billion in arms sales in 2021.
The products and services the companies on this list provide include communication and navigation systems, small arms ammunition, precision guided missiles, submarines, surface vessels, fixed and rotary wing aircraft, and battle tanks. The companies reporting the most revenue from arms sales have furnished the U.S. Air Force and Navy with hundreds of fighter jets and other aircraft, many of which have price tags of over $100 million.
Weapons procurement is only part of the picture, however, as many of the more sophisticated weapons systems used by the military are the product of years of development. The Air Force’s new long-range nuclear stealth bomber, the B-21 Raider, for example, which should be having its first flight at some point this year, was developed by Northrop Grumman, a Virginia-based contractor, over seven years before its introduction last December. (Here is a look at last year’s largest U.S. weapons contracts.)
Not only do the companies on this list often collaborate with the Pentagon on weapons development, but they often also collaborate with each other. Many weapons systems in the U.S. arsenal are so advanced that no single company can manage production from start to finish. A single fighter jet or tank may integrate an engine from one company, a computer system from another, and a gun turret from yet another.
Here are the largest American weapons manufacturers.
