WASHINGTON, D.C. – Today, Senator Andy Kim (D-N.J.) and Senator Tim Sheehy (R-M.T.) introduced the bipartisan Advanced Reactor Modernization for Operational Resilience (ARMOR) Act of 2025 to boost energy resilience and security through the use of nuclear energy at military installations and further spur nuclear energy innovation in the United States. 

“Energy resilience and innovation are at the core of shaping a strong national defense and economic future,” said Senator Kim. “Working alongside Senator Sheehy, this bill is a bipartisan tool to fuel American industry, unlock innovation, and make sure the future of nuclear energy works hand in hand with our nation’s security.” 

“In an era of emerging peer-to-peer conflicts around the world, it is critical that we adopt an all-of-the-above approach to strengthen our power infrastructure and energy independence. Energy security is national security, and I’m proud to be part of this effort to spur renewed atomic innovation and improve energy resilience at our military bases. As the birthplace of nuclear energy, it’s high time for America to yet again unleash the power of the atom. Let’s get to work,” said Senator Sheehy. 

Full text of the bill is available here. 

95% of the energy used on U.S. domestic military installations is sourced off-site on electric grids facing surging demand, which leaves the military with highly limited ability to respond to power disruptions. The ARMOR Act aims to improve energy resilience at military sites to support national defense and spur innovation in the U.S. nuclear power industry, including through: 

• Establishing a pilot program within the U.S. Army, in coordination with the Defense Innovation Unit, to deploy fixed facility advanced nuclear microreactors or small modular reactors at select Army installations to provide resilient energy for critical infrastructure by 2030.  
• Authorize multi-year contracts for up to 50 years that allow the U.S. military to obtain energy from advanced nuclear reactors and encourage the co-location of AI infrastructure and data centers.  
• Expand eligibility for the Office of Strategic Capital at the Department of Defense to designate nuclear energy and nuclear technologies as a covered area for investment, unlocking millions in federal investment to move this industry forward.
