The Space Force is playing a key role in planning for “Golden Dome,” President Donald Trump’s initiative for comprehensive air and missile defense of the homeland, leaders said this week. But actually building and fielding the ambitious idea will require a major concerted effort across the Pentagon and intelligence community.
In an executive order signed a week after his inauguration, Trump directed the Secretary of Defense to submit an outline for how to make Golden Dome a reality within 60 days. To make that happen, the Pentagon will have to clear numerous legal, technical, and cultural hurdles, said Vice Chief of Space Operations Gen. Michael Guetlein.
“Without a doubt, our biggest challenge is going to be organization, behavior, and culture,” Guetlein said at the National Security Innovation Base Summit on March 5. Golden Dome has a “magnitude of the Manhattan Project,” Guetlein added, and it’s going to take “heavy lift” across all the organizations involved.

Originally called “Iron Dome for America” after Israel’s short-range air defense system, Golden Dome would have a much larger and more complex scale, officials say. It is meant to incorporate satellite constellations for missile warning, space-based sensors, missile interceptors, and advanced communication systems.
Chief of Space Operations Gen. B. Chance Saltzman has said the Space Force will play a “central role” in Golden Dome, a point repeated by leaders at the AFA Warfare Symposium this week. But Guetlein noted that what agency is going to lead the project “hasn’t been decided yet.”
Organizations from across the Pentagon are likely to be involved, including the Missile Defense Agency, National Reconnaissance Office, U.S. Space Command, and services like the Army, Navy, and Air Force.
Integrating all of those military and intelligence operations—governed by separate legal and bureaucratic frameworks—will be one of the key challenges of the project.
“We’ve also got to break down the barriers of Title 10 and Title 50,” said Guetlein, referring to the sections of U.S. law governing intelligence and military matters. Integrating data from the intelligence community, such as real-time sensor information from satellites, and sharing it with military units “in a time-relevant manner, and get that data to the shooter, in a manner of time that can actually deter the attack” will be crucial for Golden Dome, Guetlein said.
The project will also have to rely heavily on advanced and new technologies. Col. Robert Davis, program executive officer of Space Systems Command’s space sensing directorate, stressed the need for effective “kill chains”—the process of tracking targets, processing sensor data, and passing it to interceptors. This technology, which has proven successful in Israel, will need to be adapted to a much larger scale.
“I imagine there’s maybe a strong need to continue to expand on the work that Space Force is already doing to pivot our architecture to be able to track hypersonics with the LEO and MEO layers,” Davis said at the AFA Warfare Symposium.

Lt. Gen. Philip A. Garrant, head of SSC, also said at the symposium that the groundwork for Golden Dome is underway, but much of his team’s effort is focused on understanding “what the requirements and the allocation of resources will be.” While SSC is conducting literature review to determine which technologies can be accelerated and which new innovations may be required, much of the research, for now, is aimed at determining “what might be feasible from a physics perspective.”
Earlier this year, both the Space Development Agency and the Missile Defense Agency tasked contractors with proposing solutions to meet Golden Dome’s requirements, including a hypersonic and ballistic tracking space sensor layer and proliferated space-based interceptors for boost-phase intercept. But some of these novel technologies can be a “real challenge,” said Lt. Gen. Shawn W. Bratton, the Space Force’s top officer for strategy, plans, programs, and requirements, describing the complexity of interceptors from space as “no joke of a physics problem.”
Guetlein also highlighted the need to conduct more testing and training in space, which would be crucial for improving the operational capabilities of Golden Dome.
“The authority that we would ask right out of the gate is the authority to do on-orbit training and testing that we’re not capable of doing today,” said Guetlein, adding that the service is currently very constrained in that way. “We would ask that open up so that we can increase our readiness of our of our forces on the front line, to be able to do that ‘protect and defend’ mission.”
Trump, for his part, isn’t backing away from the the Golden Dome project, mentioning it during his address to Congress this week.
“My focus is on building the most powerful military of the future,” Trump said on March 4, calling the project the first step toward realizing that vision.
By the end of this month, the White House is expecting a comprehensive plan for Golden Dome that includes a reference architecture, capabilities-based requirements, accelerated deployment of space-based sensors, plans for new interceptors, and strategies for secure supply chains and funding.
