A Democratic Congress taking office in January is likely to rename President Donald Trump's Golden Dome missile-defense program, constrain its budget and target its most contested space layer, Ars Technica reported Monday, citing current and former officials¹.

Ars said two of the effort's leading House backers, Rep. Jeff Crank of Colorado and Rep. Scott DesJarlais of Tennessee, are among Republicans leaving Congress, and that seven House members of an all-Republican Golden Dome Caucus lost or did not seek reelection¹. Rep. John Garamendi of California, described as next-senior Democrat on the House Strategic Forces subcommittee, called the system earlier this year a massive, extraordinarily expensive and ultimately inadequate defensive system, Ars reported¹.

Trump announced Golden Dome in January 2025 as a consolidation of existing missile-defense work, faster Ground-Based Interceptors and a new layer of orbiting sensors and Space-Based Interceptors, Ars said¹. Much of that work was already underway or operational, the outlet reported¹. The first roughly $24 billion was included in a partisan reconciliation package rather than the regular defense bill, Ars said, a choice Sen. Mike Rounds of South Dakota later called unnecessary¹.

The White House projects $185 billion over 10 years, a figure Ars said is hard to verify from public Pentagon details¹. The Congressional Budget Office concluded a system matching the executive order would cost about $1.2 trillion, and the American Enterprise Institute last year published architectures from about a quarter-trillion dollars without space interceptors to $3.6 trillion at the high end, Ars reported¹. Pentagon officials dispute those estimates, arguing they omit assumptions about cheap launch and mass-produced satellites¹.

Space-Based Interceptors, never flown despite decades of research, are the most ambitious layer, Ars said¹. Sen. Mark Kelly of Arizona said the cost, physics and likely reliability do not support a full-scale space intercept architecture¹. Former Air Force Secretary Frank Kendall said such a shield could push rivals to build more missiles¹. John Plumb, who oversaw military space policy in the Biden administration, said using the Golden Dome name politicized national security¹.

The $24 billion for fiscal 2026 has expired under a continuing resolution, Ars reported, and preliminary House and Senate bills for fiscal 2027 would provide only a fraction of more than $17 billion the administration sought¹. A separate $350 billion reconciliation request including Golden Dome funds did not pass the Republican Congress and is not expected under Democrats, Ars said¹. Space Force Gen. Michael Guetlein, who leads the program, told lawmakers that boost-phase intercept from space will not go to production if it cannot be done affordably at scale¹.

Industry executives told Ars that other layers, including sensors, ground interceptors and tracking, have broader support¹. Voyager Technologies chairman Dylan Taylor said the program will not be discarded wholesale¹. "There's no doubt that whatever it's going to be called, it won't be called Golden Dome," Taylor said¹. Rocket Lab CEO Peter Beck said missile defense would remain a national-security priority even if its shape and scale change¹. CSIS's Tom Karako told the Senate in September that Congress could rename the initiative in a defense bill to reduce polarization¹.
