Why It Matters

The Senate Armed Services Subcommittee on Strategic Forces convened on April 27, 2026, for a hearing on Department of Defense missile defense activities, where a top Pentagon official flatly told senators the United States has "no defense against hypersonic weapons or cruise missiles today." The Trump administration's Golden Dome initiative, which aims to fix that gap at a projected cost of $185 billion, drew sharp questions about whether Congress is being cut out of the process.

The Big Picture

The hearing was the Senate's first formal opportunity to interrogate the missile defense components of the Trump administration's $1.5 trillion FY2027 defense budget request, the largest in U.S. history. President Trump signed Executive Order 14186 in January 2025, directing the development of an integrated system to defend against ballistic, cruise, and hypersonic threats. The FY2027 budget requests $17.9 billion for Golden Dome, but nearly all of it sits in the reconciliation request, not the base budget. Politico reported in February that the program was "struggling to take shape" a year after being ordered, and appropriators said they couldn't conduct oversight in FY2026 because they still didn't know how $23 billion already appropriated would be spent.

What They're Saying

The hearing's sharpest tension came from Sen. Angus King Jr. (I-ME), the subcommittee's ranking member, who challenged the program's strategic rationale and its funding structure.

On deterrence:

  • "Why is it that we suddenly need a defense shield when we went without one for 70 years and it worked?" — Sen. King

On the budget process:

  • "This is son of OCO. It's a fund that doesn't have the oversight of the United States Congress." — Sen. King

On the current threat gap:

Marc J. Berkowitz, the Assistant Secretary of Defense for Space Policy, pushed back on King's deterrence argument: "Strategic stability cannot be based on U.S. societal vulnerability to assured retaliation. Both Russia and China have long pursued their own integrated air and missile defense systems. Their objections to U.S. missile defenses are not really about preserving strategic stability."

King fired back that Berkowitz's justification for routing 25 percent of the defense budget through reconciliation was "not a very satisfactory answer," adding: "I think it's a huge mistake, and it's one more abdication of Congress's responsibility and authority to take care of the taxpayers' money."

Lt. Gen. Heath A. Collins, Director of the Missile Defense Agency, offered a candid admission about production shortfalls: "We have been building a capacity debt where we have not maximized our production lines to meet the needs that the warfighter has identified." He declined to provide specific inventory numbers in open session, saying "the inventories are sensitive and we could take those offline."

Lt. Gen. Francisco J. Lozano, the Army's Joint Program Acquisition Executive for the Guam Defense System, offered the hearing's most straightforward update: the Guam system is "executing on schedule and on budget" at a total cost of $3.5 billion, with the bulk of systems flowing to the island in the 2027-2028 timeframe.

Political stakes: The hearing put subcommittee Chair Deb Fischer (R-NE) in a careful position. A long-standing missile defense advocate, she framed the session around Golden Dome accountability, pressing witnesses on how the program would improve posture "in a cost-effective manner." But with a Republican president's signature initiative on the line, she had limited room to press too hard. Guetlein faces the steepest personal stakes: as the program's public face, he has already told Congress that space-based interceptors, the program's most ambitious component, may be cut if they prove unaffordable, a position Axios reported ahead of the hearing. The GAO has also found that the Next Generation Interceptor program, which Collins oversees, is not periodically assessing implementation progress. Collins acknowledged the program underwent a "replan" 18 months ago due to solid rocket motor concerns, but said it remains on track for a first flight test in 2029.

The administration's threat assessment is not in dispute. Both parties agree that Russia and China are fielding hypersonic weapons the current U.S. system cannot intercept, and that existing Ground-Based Midcourse Defense interceptors were designed for a narrow rogue-state threat. Where members diverge is on whether a $185 billion layered architecture is the right answer, and whether routing most of its funding through reconciliation represents sound governance. The Bulletin of the Atomic Scientists has argued the program's promises, including intercepting "any airborne or missile threat launched from anywhere at any time," are technically implausible. King's mathematical challenge on the record, noting that 50 Guam-style point defenses could theoretically be built for the same price, was not fully rebutted, though Guetlein argued the comparison misunderstands the difference between point and area defense.

What's Next

The subcommittee's findings feed directly into the FY2027 National Defense Authorization Act markup, expected this summer. The $350 billion reconciliation component of the defense request requires a separate and politically complex legislative track. The Hill has reported that an expanding group of Senate Republicans are losing confidence in Defense Secretary Pete Hegseth's management of the Pentagon, a dynamic that could complicate the administration's ability to push through the full request without additional oversight conditions attached.

The Bottom Line

The Pentagon's own witnesses confirmed the U.S. currently cannot defend against hypersonic missiles or cruise missiles, making the case for urgent investment, while Congress's ability to oversee how that investment is spent remains an unresolved institutional fight.
