US defense spending is on track to top $1 trillion for the first time in history. Congress approved $900 billion for defense in 2026, and President Donald Trump has since proposed a staggering $1.5 trillion defense budget for 2027, the largest request in decades. Much of that money goes to weapons like the F-35, which can cost over $100 million apiece. So why are American weapons so incredibly expensive?
US military spending wasn’t always like this. In 1909, the Wright Brothers sold the first military airplane for $30,000. During World War II, Henry Ford’s Willow Run plant could efficiently crank out a B-24 bomber every hour.
But in the 1990s, the American defense industry consolidated from 51 major contractors down to just five: Lockheed Martin, Northrop Grumman, Boeing, Raytheon, and General Dynamics. That shift gave these companies enormous leverage over the Pentagon. The result? Cost overruns, missed deadlines, and weapons systems that even the US military can’t repair without going back to the contractors that built them.
