Antares Industries

Antares is building fission microreactors to enable strategic energy for critical mission capabilities on Earth, in space, and underwater. The company's mission is to deliver abundant energy from Earth to the asteroid belt through compact, deployable nuclear power systems.

Antares specializes in designing and manufacturing adaptable and scalable reactors for strategic energy applications, including space-based nuclear power and propulsion, and energy resilience for mission-critical facilities. Their approach focuses on developing portable nuclear solutions that can provide reliable power in remote and challenging environments where traditional energy infrastructure is impractical or unavailable.

The company's R1 Microreactor is a kilowatt-scale reactor designed to deliver 100-500 kWe for 4-6 years of continuous operation. The design emphasizes reliability, uptime, and manufacturability, with features that simplify deployment and reduce operational complexity.

Antares maintains a vertically integrated supply chain, giving the company control over critical aspects of reactor development and production. Their core capabilities include special purpose reactor design and manufacturing, thermal management systems, automated control systems, and precision machining of nuclear-grade graphite. This integrated approach allows Antares to develop complete power solutions rather than relying on external suppliers for key components.

The company's technology serves high-value applications in power-constrained environments, including defense installations, space exploration missions, and remote operations where conventional power generation is not feasible. By focusing on modular, transportable reactor systems, Antares aims to make nuclear power accessible for specialized applications that require reliable, long-duration energy sources in extreme and isolated environments.
