Golden Dome Is a $185 Billion Program, but Anduril Is Private. Here Are the 3 Public Companies Building It.

The U.S. Golden Dome Initiative, a $185 billion homeland missile defense system designed to protect the continental U.S. from aerial attacks, is being developed by multiple defense contractors. While private company Anduril is involved, three major publicly traded defense firms—Lockheed Martin, RTX Corporation, and Northrop Grumman—are positioned to benefit significantly from this multi-decade program, which could reach $1.2 trillion in long-term sustainment costs over 20 years.
