Golden Dome missile defense program to cost $185 billion; Anduril helping but remains private
The U.S. Golden Dome missile-defense initiative, authorized in 2025, is projected to cost $185 billion upfront with potential 20-year sustainment costs reaching $1.2 trillion. Anduril is involved in development, but the article focuses on three public prime contractors poised to benefit.
What happened
Golden Dome is an ambitious layered missile-defense system designed to protect the entire continental U.S.—over 3 million square miles—against aerial attacks using satellites with thermal cameras to detect missiles, and interceptor rockets to destroy them in mid-air. President Trump signed an executive order on January 27, 2025, to develop and deploy the system, and Congress formalized and budgeted it through the One Big Beautiful Bill Act on July 4, 2025.
The program is projected to start at $185 billion, with long-term maintenance and sustainment potentially reaching $1.2 trillion over 20 years, according to the Congressional Budget Office. Three major public defense contractors are scaling production: Lockheed Martin manufactures interceptors and command-and-control systems and was selected as sole prime for the Missile Defense Agency's Next Generation Interceptor program. RTX Corporation provides sensors and effectors including Patriot and Standard Missile systems, and has signed undefinitized contract actions (UCAs) worth $70 billion. Northrop Grumman provides low-orbit tracking satellites with heat-sensing cameras and solid rocket motors, and was awarded a $1.6 billion contract from Lockheed for propulsion components.
Anduril, a privately held company, is helping develop the system but is not named as a prime contractor in the article's coverage of the public companies positioned to benefit.
Background
Golden Dome for America is a next-generation homeland missile-defense initiative launched in 2025 by President Trump to address evolving threats, including hypersonic missiles that fly below traditional ground-based radar. The program builds on decades of U.S. missile-defense investment and involves multiple layers of detection and interception. Anduril Industries, founded in 2017 and valued at $61 billion as of May 2026, is a defense-technology company focused on autonomous systems and software; it is a member of the team developing space-based interceptor technology for the Space Force as part of the Golden Dome effort. The three public primes—Lockheed Martin, RTX, and Northrop Grumman—are among the largest U.S. defense contractors and traditionally hold the largest government contracts.
