On January 27, 2025, President Donald J. Trump issued an executive order directing the Department of Defense to develop and implement a homeland missile defense architecture to defend against "ballistic, hypersonic, advanced cruise missiles, and other next-generation aerial attacks from peer, near-peer, and rogue adversaries."¹ On May 20, 2025, President Trump asserted that this "Golden Dome for America" concept would cost $175 billion, and be completed by the end of his term.² Other cost and timeline estimates have exceeded those of President Trump.³ The Golden Dome concept and the Trump Administration's approach to homeland missile defense introduces several potential oversight and funding issues for Congress.

For example, in May 2025, the Congressional Budget Office (CBO) updated findings from 2004 and 2012 studies that assessed the cost of various space-based interceptor (SBI) architectures to counter the North Korean missile threat. (President Trump has mentioned SBIs will be part of Golden Dome.) CBO found that, depending on the desired architecture and certain assumptions made about SBI technology and despite decreasing launch costs, the notional architectures assessed in the 2004 and 2012 studies could cost from $160.7 billion to $542.4 billion over 20 years. In addition, these notional constellations were not sized for the threat posed by North Korea in 2025, nor the threat posed by all aerial threats in 2025. CBO noted that "North Korea is probably now capable of launching attacks with enough ICBMs to overwhelm the SBI defenses examined in [previous studies]." Letter from Phillip L. Swagel, director of CBO, to Senator Deb Fischer, chair, Subcommittee on Strategic Forces, Senate Committee on Armed Services, and Senator Angus S. King Jr., ranking member, Subcommittee on Strategic Forces, Senate Committee on Armed Services, May 5, 2025, https://www.cbo.gov/system/files/2025-05/61237-SBI.pdf.
