US Air Force Selects Companies for Nuclear Microreactor Deployment

This article summarizes reporting by Bloomberg and Will Wade. This article summarizes publicly available elements and public remarks.

The US Department of the Air Force has officially selected three companies to install nuclear microreactors at designated military installations. According to reporting by Bloomberg, the move signals a growing interest in fission systems as the military seeks to secure reliable power amid climbing electricity demands.

The initiative falls under the Advanced Nuclear Power for Installations (ANPI) program, a collaborative effort launched by the Defense Innovation Unit (DIU) alongside the Air Force and Army. The program aims to deploy contractor-owned and operated microreactors to ensure critical national security missions remain uninterrupted by commercial grid failures, extreme weather, or cyberattacks.

Selected Companies and Host Bases

Industry reports and public statements confirm that the Air Force has paired three commercial nuclear technology vendors with specific military bases for the pilot program. The selected companies are tasked with siting, licensing, constructing, and eventually operating the microreactors.

Antares Nuclear at Joint Base San Antonio

According to the San Antonio Express-News, California-based Antares Nuclear has been selected to develop a prototype microreactor at Joint Base San Antonio (JBSA) in Texas. The company plans to build a sodium heat pipe-cooled microreactor capable of generating between 100 kilowatts and 1 megawatt of electricity. Designed to operate for years without refueling, the system is compact enough to be transported by truck or aircraft.

Radiant Industries at Buckley Space Force Base

As announced in a company press release published by Morningstar, Radiant Industries will deploy its Kaleidos microreactor at Buckley Space Force Base in Aurora, Colorado. The Kaleidos unit is a 1-megawatt failsafe reactor designed for portability and zero-emissions operation. Radiant aims to deliver its first reactors by 2028, following testing at the Idaho National Laboratory.

Westinghouse at Malmstrom Air Force Base

Reporting from World Nuclear News confirms that Westinghouse Government Services has been tapped to provide a microreactor for Malmstrom Air Force Base in Montana. Like the other selected sites, Malmstrom was chosen following extensive environmental and logistical analyses, prioritizing locations with critical mission requirements and suitable land availability.

The Strategic Push for Energy Resilience

The Department of Defense has increasingly prioritized energy independence for its remote and critical installations. Microreactors, which typically generate under 20 megawatts of power, offer a factory-built, transportable alternative to traditional large-scale nuclear plants. They can operate entirely independent of the local electric grid.

The ANPI program builds on previous Department of Defense initiatives, such as Project Pele, which focused on mobile microreactors. However, ANPI specifically targets fixed installations, allowing commercial vendors to own and operate the reactors while the military purchases the reliable power.

In a public statement regarding the ANPI initiative cited by the San Antonio Report, Michael Borders, Assistant Secretary of the Air Force for Energy, Installations, and Environment, emphasized the strategic necessity of the program.

“By integrating advanced nuclear technology… we are guaranteeing that our most critical national security missions will never be held at risk by a power outage,” Borders stated.

The Air Force anticipates that these microreactors will be fully installed and operational by 2030 or earlier, pending successful environmental reviews and licensing approvals from the Nuclear Regulatory Commission.

AirPro News analysis

The Air Force’s selection of Antares, Radiant, and Westinghouse represents a pivotal transition from theoretical research to practical deployment of next-generation nuclear technology. As military installations face escalating power demands from advanced computing, electrification, and continuous global operations, reliance on aging civilian power grids poses a significant vulnerability. By championing the ANPI program, the Pentagon is not only securing its own infrastructure but also acting as a crucial early adopter for the commercial microreactor industry. This federal backing could accelerate the regulatory and manufacturing pathways needed to make microreactors viable for civilian applications, such as powering remote communities, disaster relief efforts, or energy-intensive data centers. We view this as a strong indicator that the regulatory hurdles historically associated with nuclear energy are being streamlined for national security priorities.

Frequently Asked Questions

What is a nuclear microreactor?

A microreactor is a small, factory-built nuclear fission reactor designed to be easily transportable by truck, rail, or aircraft. They typically generate between 1 and 20 megawatts of electricity and can operate for years without needing to be refueled, making them ideal for remote or off-grid locations.

When will the Air Force microreactors be operational?

The Department of the Air Force expects the microreactors at Joint Base San Antonio, Buckley Space Force Base, and Malmstrom Air Force Base to be deployed and operational by 2030 or earlier.

Who will own and operate the reactors?

Under the Advanced Nuclear Power for Installations (ANPI) program, the microreactors will be contractor-owned and operated. The selected commercial companies will handle the licensing, construction, daily operations, and eventual decommissioning of the units.
