The United States government has a budget of over $858 billion for national defense in 2023. Half of the military spending goes to the private sector and largest defense companies, amounting to over $400 billion.

The national defense revenue generated from military contracts has, in turn, driven up the revenue state-wide. In 2021, Alabama’s $12.2 billion defense worth of contracts and Connecticut’s $18.4 billion worth of contracts represented nearly five percent of the states’ economies.

Here are the top ten largest defense contractors in the U.S. in 2022.
