Trump’s Golden Dome Missile Defense System Could Cost $1.2 Trillion Over Two Decades, CBO Estimates
President Donald Trump announced his "Golden Dome" project from the Oval Office on May 20, 2025 —Chip Somodevilla—Getty Images(SeaPRwire) - A new estimate from the Congressional Budget Office suggests that President Donald Trump’s proposed “Golden Dome” missile defense system could cost up to $1.2 trillion over two decades, far surpassing the $175 billion figure he originally cited.The nonpartisan budget office noted that its analysis was based on a hypothetical approach rather than a finalized blueprint, as the Defense Department has not yet publicly outlined the complete structure of the ambitious system, which Trump has promoted as a permanent solution to the threat of missiles targeting the United States.The report provides one of the most detailed assessments to date of how costly and challenging the project could be, highlighting the significant technological and financial hurdles involved in creating a futuristic shield against missile attacks. The initiative, dubbed the “Golden Dome for America,” was launched via an executive order signed by Trump during the first week of his second term. The directive called for a comprehensive missile defense network designed to detect, track, and intercept missiles at various stages of their flight, including from space.Gen. Michael Guetlein, the Pentagon official leading the effort, stated in March that the program would require approximately $185 billion through 2035—about ten years—for what he described as the system’s core architecture.However, the CBO adopted a much broader time frame in its analysis and projected that acquisition costs alone would exceed $1 trillion over 20 years. The majority of these expenses are linked to space-based interceptors—satellites equipped with weapons intended to neutralize missiles shortly after launch. According to the report, roughly 70% of acquisition spending would go toward this space-based component, including a proposed network of around 7,800 satellites. Buying enough orbiting interceptors to counter about 10 incoming ballistic missiles is estimated to cost approximately $720 billion.The concept draws inspiration from Israel’s layered air-defense systems, commonly known as the Iron Dome, which have successfully intercepted rockets and missiles launched by Iran and allied militant groups. However, Israel’s systems are tailored to protect a smaller geographic area and are effective only against shorter-range threats. By contrast, the American version aims to safeguard the entire continental United States, as well as Alaska and Hawaii, from long-range ballistic and hypersonic missiles.“Over the past 40 years, instead of decreasing, the threat posed by next-generation strategic weapons has grown more severe and complex,” Trump said in his executive order, pointing to advancements in hypersonic and ballistic missile technologies by Russia, China, and other adversaries.At the time, he expressed a goal of having the system operational before the end of his term in January 2029—an aggressive timeline given the scale of technological innovation and infrastructure expansion required.The CBO indicated that the system modeled in its analysis could effectively defend against a limited attack from a regional adversary such as North Korea but warned it might still be overwhelmed by a large-scale missile barrage from Russia or China.Space-based interceptors remain among the most controversial and expensive aspects of the proposal. General Guetlein himself has acknowledged the financial risks associated with this segment of the program. During testimony before lawmakers last month, he stated that if the Pentagon cannot develop such interceptors affordably, “we will not move forward with production.”Congress has already begun directing substantial funding toward the initiative. Last year’s Republican reconciliation bill, known as the One Big, Beautiful Bill Act, allocated roughly $25 billion to enhance the Defense Department’s integrated air and missile-defense systems tied to the Golden Dome. In its latest budget request, the Pentagon urged Congress to approve another reconciliation bill later this year, seeking an additional $17 billion for the program.The Trump Administration maintains that the initiative is essential to counter increasingly sophisticated missile threats and to modernize U.S. homeland defense capabilities. However, the new estimate is expected to intensify congressional scrutiny regarding the project’s technical feasibility, strategic necessity, and long-term financial sustainability.Sen. Jeff Merkley, a Democrat from Oregon who requested the CBO analysis, strongly criticized the plan following the report’s release, describing it as “nothing more than a massive handout to defense contractors funded entirely by working Americans.” This article is provided by a third-party content provider.
