In a bold announcement from the Oval Office on Tuesday, President Donald Trump revealed new details about one of the most ambitious national defense projects in U.S. history: the Golden Dome missile shield.
Flanked by senior military officials and Republican senators, Trump outlined his vision for a cutting-edge, layered missile defense system that will span land, sea, and space.
He estimated the cost at $175 billion and projected the system would be fully operational within the next three years—before the end of his second term.
“I’m pleased to announce that we have officially selected an architecture for this state-of-the-art system that will deploy next-generation technologies across the land, sea and space, including space-based sensors and interceptors,” Trump declared.

“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’re launched from space. And we will have the best system ever built.”
At the helm of the project will be Gen. Michael Guetlein, currently vice chief of space operations for the U.S. Space Force.
Guetlein brings deep expertise, having previously led Space Systems Command and served in senior roles at both the National Reconnaissance Office and the Missile Defense Agency—two critical entities in shaping the Golden Dome’s architecture.

“I greatly appreciate your trust in me … and your trust in the team to deliver this,” Guetlein said to Trump during the announcement. “It is a great day for America.”

Trump’s focus on a next-generation homeland missile defense system began early in his second presidency, when he issued an executive order mandating a 60-day study of possible architecture options.
The result is a proposed system that aims to counter not just threats from rogue nations like North Korea and Iran—as existing systems are designed to do—but also more advanced threats from peer adversaries like China and Russia.
The plan includes ground-based interceptors, sea-based defenses, and most notably, space-based sensors and interceptors.
Trump referenced the inclusion of space-based and hypersonic interceptors in the architecture, but did not provide further details on timelines or capabilities.

These advanced elements pose significant technical challenges, as many have yet to be developed. Hypersonic interceptors, for example, are not expected to be field-ready until the mid-2030s.
Nevertheless, some foundational components of the Golden Dome are already in development.
These include a space-based tracking and detection layer consisting of satellites and sensors designed to identify high-end missile threats.
These efforts are part of the Space Development Agency’s Proliferated Warfighter Space Architecture, which could be expanded to support Trump’s vision.
Support among congressional Republicans for Golden Dome appears strong. In February, Sens. Dan Sullivan (R-Alaska) and Kevin Cramer (R-N.D.), who were present at Tuesday’s announcement, introduced the Golden Dome Act—a bill proposing $19.5 billion in funding for fiscal year 2026.
Their proposal calls for expanding missile defense capabilities on U.S. territory, including the addition of Aegis Ashore Systems and the use of surveillance blimps to detect complex threats.
Fort Greely’s Ground-Based Midcourse Defense system in Alaska would also be upgraded and complemented by a new interceptor site on the East Coast.
The House GOP has already included $25 billion for the project in its budget reconciliation plan for fiscal 2025, a figure Trump cited in his remarks. When asked about the feasibility of securing the full $175 billion in funding, Trump expressed confidence.
“It’s amazing how easy this one is to fund,” he said. “Some funding is tough and some is easy. When we say we’re going to save everyone’s lives in a crazy world, it seems to be very easy to get.”
Trump emphasized that Golden Dome systems will be made in America, though no specific contracts have been awarded yet. Sen. Jim Banks (R-Ind.) pointed to the role of Indiana-based L3Harris in developing the current space-based sensor network.
Sen. Sullivan also cited major defense contractors Lockheed Martin and RTX for their contributions to ground-based missile interceptors and indicated that the project would welcome participation from nontraditional defense firms as well.
“It’s all across the board in terms of companies. Sen. Cramer and I just met with a bunch of them last week that are interested in this,” Sullivan said.
“Our technology sector is head and shoulders above any other place in the world, and they’re going to be a key part of this.”
Though questions remain about the feasibility of Trump’s timeline—especially with the most advanced elements still in early development—the Golden Dome project marks a significant escalation in America’s missile defense ambitions.
If successful, it would redefine national defense infrastructure and solidify the U.S. lead in space-based security capabilities for decades to come.
