Golden Dome Missile Defense Faces Funding Uncertainty

At the start of the current fiscal year, the Golden Dome missile-defense program has no operating funds. The Pentagon’s FY 2027 base budget includes only $400 million, while the program has relied on a $25 billion reconciliation package passed in July 2025 and a pending $17 billion request in a new $350 billion reconciliation proposal. Because a continuing resolution holds spending at prior-year levels, the program lacks a baseline appropriation, leaving its near-term development in jeopardy.

President Donald Trump announced in January 2025 that the Department of Defense would build an expansive homeland missile-defense architecture, later formalized by an executive order in February 2025. Originally dubbed “Iron Dome for America,” the initiative was renamed “Golden Dome.” The concept envisions a layered system of sensors, ground- and space-based interceptors, and integrated command-and-control to counter drones, ballistic missiles, hypersonic weapons, and advanced cruise missiles. The Trump administration chose to fund it primarily through budget reconciliation, bypassing the traditional bipartisan appropriations process.

• Pentagon estimate: Space Force General Michael Guetlein cited a $185 billion total cost for development, deployment, and operation.

• Initial appropriations: The “One Big Beautiful Bill Act” allocated $25 billion in July 2025; roughly 90 percent had been obligated by mid-August.

• Current requests: The Pentagon seeks an additional $17 billion in the upcoming reconciliation package, while the FY 2027 base budget includes only $400 million for Golden Dome.

Lawmakers Push for Bipartisan Solution to Golden Dome Funding

Senator Mike Rounds (R-South Dakota) argued that using reconciliation was unnecessary and urged a return to a bipartisan appropriations approach. Tom Karako, director of the Missile Defense Project at CSIS, highlighted the lack of strategic messaging and questioned how protection decisions would be made, noting that the proposed architecture would likely shield only major cities and critical infrastructure.

Two divergent cost projections exist: the CBO’s $1.2 trillion estimate versus the Pentagon’s $185 billion figure. There is also no consensus on the operational scope of Golden Dome, with lawmakers and experts disagreeing on whether it will provide comprehensive national coverage or focus on select high-value targets.

Lawmakers are urging the inclusion of Golden Dome funding in an underlying appropriations bill rather than another reconciliation measure. Proposals include creating a permanent oversight entity or merging the program with the Missile Defense Agency to streamline authority and resources. The outcome will determine whether Golden Dome can secure stable financing for its FY 2027 tranche and continue development.
