Commentary
Two months ago, President Trump directed the development of a national missile defense system initially dubbed “Iron Dome” and rebranded in February as “Golden Dome.” Its stated purpose is to establish a layered and integrated defense shield to protect the United States against ballistic missiles, hypersonic weapons, advanced cruise missiles, and other emerging aerial threats.
The executive order acknowledges that similar ambitions are not new. It references President Ronald Reagan’s Strategic Defense Initiative, noting that while it “resulted in many technological advances,” the program was ultimately “canceled before its goal could be realized.”
However, the current order justifies renewed urgency, asserting that “over the past 40 years, rather than lessening, the threat from next-generation strategic weapons has become more intense and complex.” It specifically cites adversaries’ development of “next-generation delivery systems and their own homeland integrated air and missile defense capabilities.”
Success in realizing this monumental undertaking will depend on avoiding past pitfalls while leveraging existing technologies and institutional expertise.
Lessons Learned From the 1980s
President Reagan’s Strategic Defense Initiative (SDI) of the 1980s—“Star Wars“—sought to create a space-based shield against Soviet ICBMs. Despite its astronomical vision, SDI never fully materialized due to several critical factors: technological overreach, sky-high costs, lack of coordination, and unrealistic goals without clear, phased implementation plans. The SDI called for—among other things—directed energy weapons to defeat enemy ICBMs at a time when such weapons were either embryonic or still in the realm of science fiction. When the INF and START treaties were signed in 1987 and 1991 respectively, the need for SDI quickly faded along with the Cold War.The need for missile defense however, did not. The Golden Dome executive order indirectly refers to the SDI when it says, “Over the past 40 years, rather than lessening, the threat from next-generation strategic weapons—including hypersonic—has become more complex with the development of next-generation delivery systems by our adversaries.” Hopefully, unlike Disney’s recent efforts, this Star Wars sequel won’t be a disappointment.
The key difference between 2025 and 1985 is that much of the technology required already exists and has been battle-tested—most notably by Israel, and to a lesser extent Ukraine. Keep in mind, in the 1980s, the new fielded Patriot wasn’t even rated to reliably engage short-range ballistic missiles, to say nothing of ICBMs. Even anti-satellite weapons were on the very cutting edge.
Building on Proven Technologies
Golden Dome is an opportunity to leverage existing, proven defense technologies rather than incurring the massive cost-reimbursement contracts of all-new development. The U.S. has been refining these capabilities over decades through AIAMD, THAAD, Patriot, Aegis BMD, and the Ground-based Midcourse Defense (GMD), along with close, ongoing cooperation with the Israelis. These established systems provide the initial foundation upon which the Golden Dome can build. What is needed is to bring these systems all together with improved short-range sensors, and network them together on a scale like the planned Joint All-Domain Command and Control (JADC2) system.The institutional air defense knowledge housed within major contractors like Lockheed Martin and Raytheon represents billions of dollars in prior investment and millions of engineering hours. Additionally, these companies possess large amounts of expertise in large-scale integration projects that will be crucial to the Golden Dome’s success. Their experience with complex command and control architectures gives them unique capabilities to tackle the integration challenges ahead.
Lessons in Integration
America’s defense challenges differ substantially from those of our allies and adversaries. But there are still valuable lessons to be drawn from successful past integration efforts. The development of layered defense networks by other nations demonstrates that combining technologies from multiple sources into a coherent system is possible with proper coordination and leadership.For Golden Dome to succeed, the DoD must foster coordination between established defense contractors and innovative technology companies that reflect America’s unique strategic position and continental scale. Given the vastly different geographic and threat profile facing the United States, Golden Dome will need to pioneer new approaches rather than attempting to replicate foreign models.
The Challenge
Bill Morani, undersecretary of defense for acquisition and sustainment, noted that Golden Dome is “[both a] monster systems engineering problem [and] a monster integration problem.” The Missile Defense Agency (MDA) has established a phased Golden Dome timeline for capability delivery from 2026 to past 2030. Meeting these deadlines on a project of this scale will require an enormous amount of coordination between government agencies, stakeholders, and defense contractors.Established defense prime contractors offer critical advantages to the U.S. industrial base in this area. Their decades of experience working with the MDA, U.S. Northern Command, the military services and other defense agencies have created institutional knowledge and networks difficult to replicate. These companies understand the complex regulatory environment, certification requirements, and interoperability standards needed to incorporate a defense system this vast. They also bring the ability to manufacture at scale.
At the same time, tech hyperscalers and defense innovators are essential to the Golden Dome’s success. Microsoft, Amazon Web Services, and Google bring cloud infrastructure and advanced AI capabilities that will be critical for processing the massive data streams required for an integrated defense network. Companies like ShieldAI offer autonomous systems expertise, while Anduril and Palantir bring computational prowess and innovative approaches to data fusion. Their agility and fresh perspectives represent valuable additions to the defense industrial ecosystem.
The integration of these complementary capabilities is what will make Golden Dome possible. Large prime contractors bring irreplaceable experience in system integration, scaling production lines, and proven hardware platforms, while tech-focused firms contribute cutting-edge AI/software capabilities, cloud infrastructure, and novel approaches to data management needed for next-generation defense solutions.
Starting Small: Guam
Rather than beginning with the overly ambitious goal of covering the contiguous United States, Golden Dome would benefit from a focused approach similar to Israel’s incremental development of its multi-tiered defense system. Guam presents an ideal testbed—a crucial and geographically contained area facing substantial threat from China, including thousands of drones and hundreds of cruise missiles and tactical ballistic missiles.Ongoing and previous defense efforts on Guam have provided valuable data. A THAAD battery has been emplaced there since 2013. The temporary deployment of a U.S. Iron Dome battery to the island in 2021 demonstrated both possibilities and limitations of current technology when adapted to Guam’s defense needs. The MDA successfully tested the Aegis Guam System in December of 2024. The U.S. Army is planning on building out the multi-capable Task Force Talon already deployed on the island into a larger Guam Defense System (GDS) task force with improved short-range air and missile defense capabilities. Starting with a fully integrated defense of Guam would provide measurable success criteria, help refine integration approaches and establish protocols that could later be scaled to larger areas such as the National Capital Region, Hawaii, and Okinawa.
The Way Ahead
Golden Dome needs clear, achievable milestones with tangible benefits at each stage. The defense of Guam represents an ideal first objective—strategically important, geographically defined, and facing concrete threats. Success there would validate the approach before expansion to other critical areas.The Missile Defense Agency’s phased approach shows a keen awareness of this need for incremental progress and gates. By leveraging existing technologies and industrial capabilities while incorporating innovative approaches from newer companies, the DoD can maximize returns on taxpayer investment in an era of increasing defense efficiencies while accelerating deployment timelines.
Conclusion
The Golden Dome initiative represents America’s most significant integrated missile defense undertaking since the Strategic Defense Initiative. But unlike SDI, today’s effort benefits from mature technologies, battle-tested systems and proven capabilities, and decades of institutional knowledge within our defense industrial base.Without focused leadership and integration expertise, the President’s decree risks becoming like Coleridge’s unfinished poem “Kubla Khan”—a grand vision interrupted. Just as the golden dome of Xanadu existed only as a fragmented vision in a dream, so too might America’s Golden Dome remain incomplete without the right military-industrial partnerships and strategic approach.
For Golden Dome to succeed where SDI faltered, it must incorporate the solidity of established defense primes with the liquid agility of newcomers, all while keeping costs in check and timelines tight. The DoD faces a daunting challenge, but with Guam as a proving ground and battle-tested technologies as building blocks, the initiative stands a fighting chance of fulfilling the President’s vision: a shield capable of protecting American power projection in an era of proliferating threats.
