Contact Congress about S. 2389: ARMOR Act of 2025

The Army would test advanced nuclear reactors on selected U.S. bases. Military departments could also sign nuclear power contracts for up to 50 years.

Modern Action explains legislation in plain English, helps you choose whether to support, oppose, or ask for changes, and drafts a message tied to the bill, your stance, and the elected officials who can act on it.

ARMOR Act of 2025 is a Senate bill in committee. The latest recorded action: Read twice and referred to the Committee on Armed Services.

Latest action on S. 2389: Read twice and referred to the Committee on Armed Services.

Who this affects: This bill mainly affects Army bases chosen for the pilot and the people who live or work near them. It also affects reactor companies, military energy planners, and the Nuclear Regulatory Commission, which licenses nuclear reactors. Other military departments could join the program if they get approval and notify Congress.

Why this matters: Military bases rely on steady power, and this bill would test nuclear reactors as a backup or main source for critical systems. That could help bases keep operating if the civilian power grid fails. It could also shape a new market for small nuclear reactors through long military contracts. The costs, safety effects, and community impacts are not fully spelled out in the bill.

Key provisions in S. 2389

  • The Army would create a pilot program for advanced nuclear power on selected U.S. Army bases. It could use a fixed micro-reactor or a small modular reactor.
  • The Army would aim to power critical base infrastructure with an advanced nuclear reactor by December 31, 2030.
  • The Army must consider letting a private contractor own and run the pilot reactor. It must also consider using a commercial license from the Nuclear Regulatory Commission, the federal nuclear safety agency.
  • Reactors could be placed near artificial intelligence systems and data centers when that fits military needs.
  • Each pilot reactor must be able to make up to 300 megawatts of power.
