Trump’s “Golden Dome” Missile Shield: A $175 Billion Vision with Global Ambitions
US President Donald Trump is pushing forward with his ambitious “$175 billion Golden Dome” missile defense project, aiming to establish a vast satellite-based shield against threats from nations like China and Russia. Announced in May, the initiative is now formally launching its procurement and testing phases, with a target completion date of January 2029, coinciding with the end of his projected second term.
Inspired by Israel’s Iron Dome but designed to be “far more extensive,” the Golden Dome envisions a massive constellation of hundreds of surveillance and interceptor satellites. These would work in concert with expanded ground and multi-domain sensors to detect, track, and destroy enemy missiles shortly after launch.
To lead this monumental undertaking, Trump has tapped US Space Force General Michael Guetlein. Key defense contractors including L3Harris Technologies, Lockheed Martin, and RTX Corp (formerly Raytheon Technologies) are expected to provide core components.
Beyond domestic efforts, Trump is actively seeking international collaboration. Japan, under Prime Minister Shigeru Ishiba, has discussed potential partnerships on missile defense technology, with some reports suggesting Tokyo’s involvement could strategically benefit ongoing trade talks. Canada has also expressed interest in joining the project.
While a significant $25 billion in initial funding has been included in a Republican spending bill, the project faces scrutiny. Experts, including the Congressional Budget Office, have raised concerns about its feasibility, timely execution, and potential for costs to soar beyond the initial estimate. There are also broader questions about the technical challenges of space-based missile defense and its potential to ignite a new arms race.
