On May 20, 2025, President Donald Trump introduced plans for the Golden Dome, an innovative space-based missile defence system to safeguard the United States against advanced aerial threats.
The announcement, which took place at the White House, detailed a $175 billion project led by U.S. Space Force General Michael Guetlein. The system is expected to be operational by 2028, marking the United States’ first space-based weapon system.
What Is the Golden Dome System?
The Golden Dome integrates ground- and space-based technologies to detect, track, and intercept missiles at various flight stages, including pre-launch and mid-air. It targets cruise, ballistic, and hypersonic missiles, as well as drones, whether conventional or nuclear. Pentagon chief Pete Hegseth emphasised its role in enhancing existing defences, using space-based sensors and interceptors to counter “next-generation” threats.

Inspired by Israel’s Iron Dome, which intercepts short-range projectiles, Golden Dome has broader ambitions, addressing sophisticated missile threats from adversaries like Russia and China, as outlined in the 2022 Missile Defence Review. Trump called it “vital for the survival” of the U.S., capable of neutralising missiles launched globally, including from space.
Trump announced an initial $25 billion investment, with the total cost estimated at $175 billion, to be absorbed over 20 years. However, the Congressional Budget Office suggests costs could exceed $500 billion, highlighting project scope uncertainties. Congressional Republicans have proposed $27 billion in funding, including $5.6 billion for space-based interceptors and $2 billion for air-moving target satellites.

The system is slated for operation by 2028, aligning with the end of Trump’s term. General Michael Guetlein, a four-star Space Force officer with 30 years of missile defence expertise, will oversee development. The Pentagon plans to detail a “path forward” soon, with initial devices launching in collaboration with HP by late 2025, showcased at InfoComm 2025.
Canada’s Potential Involvement
Trump noted Canada’s interest in joining the Golden Dome initiative to extend protection against missile and drone attacks. Canada’s role remains unclear, but the collaboration signals potential North American defence integration.
Trump: "Think of it — you're shooting bullets out of the air. I'm also pleased to report that the one big beautiful bill will include $25 billion for the golden dome to help construction get underway. That's the initial sort of down-posit. We're talking about $175 billion total… pic.twitter.com/T4JelIilYY

Russia and China have criticised the Golden Dome, calling it “deeply destabilising” and warning it could turn space into a “battlefield.” The Kremlin argues it strengthens combat operations in space, raising concerns about an arms race. These objections underscore the geopolitical tensions surrounding the project.
Strategic Implications
Proponents, including national security correspondent Bill Gertz, view Golden Dome as a “strategic trump card” against China’s missile capabilities. However, critics argue that its technological feasibility is unproven, and its high cost and expansive scope may strain budgets. The involvement of Elon Musk’s SpaceX, a reported frontrunner for construction, adds intrigue and raises questions about execution.
