S2142119th Congress

GOLDEN DOME Act of 2025

Sponsored By: Senator Dan Sullivan

Introduced

Summary

Golden Dome all‑domain missile defense architecture would create a nationwide layered system to detect and defeat missile and unmanned‑system threats across sea, undersea, land, air, space, and cyberspace. It would give a single Program Manager sweeping acquisition, hiring, and technical authorities to speed development and fielding of interceptors, sensors, and nonkinetic tools.

Show full summary
  • Department of Defense leaders and operators would get a new Golden Dome Program Manager with milestone and contracting authority, direct hiring, and original classification powers to accelerate procurement and operations.
  • The space and defense industrial base would face accelerated procurements and competition requirements, including at least 40 Hypersonic and Ballistic Tracking Space Sensor vehicles and protections to keep multiple vendors viable.
  • Combatant commanders and testing teams would work to a tight schedule: a mandatory all‑domain strategy within 1 year, a virtual exercise within 540 days, semiannual live‑fire tests thereafter, and plans to field up to 80 Next Generation Interceptors for testing and initial fielding by January 1, 2028.

*Authorizes $23.0 billion for fiscal year 2026 to carry out the Act.*

Bill Overview

Analyzed Economic Effects

9 provisions identified: 9 benefits, 0 costs, 0 mixed.

AI fusion system for early warning

If enacted, the Secretary of Defense would be required to speed up development and rapid prototyping of an AI/ML information‑fusion platform. The platform would use a common data layer to combine sensors across air, land, sea, space, and cyber for faster warning and sensor/effecter integration. Work would prioritize rapid prototypes and high‑TRL software.

More drone and non-kinetic powers

If enacted, the bill would expand DoD authorities to mitigate unmanned aircraft and speed development of non‑kinetic defenses. It would allow delegation of authorities, broaden mitigation tools (including remote ID and other measures), let DoD support other agencies, and exempt certain technology and procedure information from FOIA and state disclosure laws. It would also push rapid work on cyber, AI battle management, electromagnetic, directed‑energy, and high‑power microwave defenses.

More interceptors at Fort Greely

If enacted, the Program Manager would expand Next Generation Interceptor production and build silos at Fort Greely to field up to 80 interceptors. The bill would require testing and initial fielding to be completed not later than January 1, 2028. This is meant to increase homeland interceptor capacity.

New Golden Dome program manager powers

If enacted, the Secretary of Defense would create a senior Golden Dome Program Manager with broad acquisition, hiring, contracting, and budget authorities. The manager would report near the top of the Joint Chiefs' order and oversee development, testing, and sustainment for Golden Dome. The manager would hold special authorities like classification and expedited construction to speed program delivery.

One-year national missile strategy

If enacted, the Secretary of Defense would have one year to write a holistic, time‑bound all‑domain missile defense strategy. The plan would name critical infrastructure to defend, list adversaries and threat types, and include layered sensors from seafloor to space and cyberspace. It would also require plans for secure command software, a clear human chain of command, and use of commercial solutions and rapid manufacturing.

Buy 40 hypersonic tracking satellites

If enacted, the Department of Defense would be required to procure at least 40 Hypersonic and Ballistic Tracking Space Sensor (HBTSS) space vehicles by December 1, 2025. These vehicles would add space‑based tracking for hypersonic and ballistic threats and accelerate related satellite procurement.

Huge 2026 funding for Golden Dome

If enacted, Congress would authorize about $23 billion for fiscal year 2026 for Golden Dome programs. The bill lists many line items, such as $500 million each for SM-3 Block 1B and SM-3 Block IIA, $1 billion for ground mobile interceptors and radars, and multi‑billion dollars for space sensors and hypersonic tracking. The money would pay for procurement, research, and construction across missile defense systems and related sensors.

Stronger testing rules and reports

If enacted, Golden Dome would start with a virtual exercise within 540 days of enactment and require semiannual live‑fire tests of mission‑essential systems after that. Test plans must go to congressional defense committees 90 days before each test. The bill also requires initial and annual reports on rules that slow testing and monthly briefings if tests are delayed.

Protect space industry and competition

If enacted, agencies would be directed to maximize open competition for mission‑critical low Earth orbit tactical data systems. The bill would require competitive procurements, resilient interfaces and standards, and guidance to avoid major contraction of the space industrial base. It would also let the Space Development Agency speed up tranches 3–5 and keep SDA independent inside the Space Force while exempting it from the JCIDS process.
