House subcommittee debates ‘Golden Dome’ policy shift and risks to strategic stability

At a House Armed Services Committee Strategic Forces Subcommittee hearing, lawmakers and Defense Department witnesses debated the administration’s “Golden Dome for America” executive order and whether a comprehensive homeland missile‑defense architecture would strengthen or undermine strategic stability.

The issue moved quickly from technical design to policy risk. Ranking Member Seth Moulton warned that Golden Dome “completely upends” the longstanding U.S. reliance on nuclear deterrence and urged the committee to ask whether expanded missile defenses might increase incentives for an adversary to strike first. “More missile defense is not necessarily better if it upsets strategic stability,” Moulton said. He added that the committee must weigh “how will expanding U.S. missile defense today impact our strategic stability tomorrow?”

Why it matters: The debate ties a large potential investment in homeland defenses to global deterrence dynamics. Advocates say integrating sensors, defeat mechanisms and command‑and‑control across layers will protect the homeland against ballistic, cruise and hypersonic threats. Detractors say an ambitious shield could alter adversary calculations and spur arms competition with Russia and China.

Department of Defense witnesses framed the executive order as a policy shift in scope. Andrea Yaffe, performing the duties of the assistant secretary of defense for space policy, told the committee that the executive order directs the department to “develop and field a next generation missile defense shield” that will include “cutting edge domain awareness systems, kinetic and non‑kinetic missile defeat capabilities, and advanced command control and battle management systems.” The Missile Defense Agency’s director, Lieutenant General Heath Collins, said MDA is “laser focused on improving our U.S. homeland defenses” and will leverage a layered, integrated approach.

Several witnesses noted bipartisan elements and long‑standing studies. The subcommittee record includes a 2019 Missile Defense Review reference and a 2023 bipartisan Congressional Commission on Strategic Posture report that urged deployment of a comprehensive integrated air and missile defense system. Ranking Member Moulton cited the 2019 policy statement that the U.S. “relies on nuclear deterrence to address the large and more sophisticated Russian and Chinese intercontinental ballistic missile capabilities” and said Golden Dome would be a major break from that approach.

Discussion versus direction: Most exchange on the record was discussion and oversight. Andrea Yaffe stated the Office of the Secretary of Defense for Policy has coordinated early architecture work and said the department intends, once the architecture is decided, to “go to phase 2 and to lead and conduct a theater missile defense review.” That was presented as an intended staff action and planning step, not a committee directive or formal decision.

What the committee pressed for next: Members asked the department to explain the strategic rationale, to show how Golden Dome would interact with the nuclear deterrent, and to provide detailed architectures and risk assessments. No formal committee action or vote occurred during the open hearing.

Ending: The hearing kept strategic stability at center stage: some members urged accelerated investment; others urged caution that a major new defensive shield could change incentives for adversaries. The open session concluded with members seeking additional technical and strategic analysis before funding or legislative decisions are made.
