President Donald Trump has announced an ambitious $175 billion initiative to build what he calls the "Golden Dome," a next-generation missile defense system designed to shield the United States from a wide range of missile threats, including those launched from space or across the globe. The announcement was made Tuesday in the Oval Office, with Defense Secretary Pete Hegseth and General Michael Guetlein of the U.S. Space Force joining the president for the briefing.
Project Scope and Leadership
The Golden Dome aims to create a multi-layered defense network that integrates land, sea, and—most notably—space-based technologies. The system will leverage a constellation of satellites equipped with advanced sensors and interceptors capable of detecting, tracking, and neutralizing ballistic, hypersonic, and cruise missiles. Trump emphasized that the shield would be "fully operational before the end of my term," with an initial $25 billion allocated from a pending congressional appropriations bill to jumpstart the project.
General Michael Guetlein, currently the Vice Chief of Space Operations, has been appointed as the program's lead. Guetlein brings extensive experience from the Space Force and the National Reconnaissance Office, and is tasked with integrating the Golden Dome into existing U.S. defense frameworks.
"Once fully constructed, the Golden Dome will be capable of intercepting missiles even if they are launched from other sides of the world and even if they are launchedfrom space, President Trump stated during the announcement.
Strategic Vision and Challenges
The Golden Dome is modeled as a U.S. answer to Israel's Iron Dome but is envisioned on a much larger and more technologically advanced scale, utilizing thousands of satellites for early warning and interception. Trump cited the recent use of Iron Dome during regional conflicts as inspiration, vowing that the U.S. system would be "the greatest dome of them all".
The initiative faces significant hurdles, including political scrutiny over its massive price tag, questions about the procurement process, and the involvement of private sector partners such as SpaceX, Palantir, and Anduril. Democratic lawmakers have voiced concerns about transparency and oversight, especially given the project's scale and the potential for cost overruns.
Despite these challenges, Trump and his administration are pushing for rapid development, positioning the Golden Dome as a generational investment in national security. The Congressional Budget Office has noted that a truly comprehensive missile shield could cost more than $500 billion over two decades, making the three-year, $175 billion target particularly ambitious.
Internationally, Trump revealed that Canada has expressed interest in joining the Golden Dome network, with discussions underway about cooperation and cost-sharing.
