Antares develops small modular reactors capable of producing roughly 100 kilowatts to 1 megawatt of electricity and designs its reactors to use TRISO fuel, which encapsulates uranium in carbon and ceramic shells. Its Mark-0 demonstration reactor reached criticality on June 4 at the Idaho National Laboratory. Antares is a finalist in the Pentagon’s Advanced Nuclear Power for Installations program and is pursuing deployments on Air Force bases in Colorado and Montana. The company plans to bring its first electricity-producing reactor online next year and targets military deployments in 2028. Financially, Antares has raised a total of $604 million to date, including a $96 million Series B in December and the $470 million Series C. The broader advanced nuclear sector faces challenges such as an immature U.S. supply chain and near-term cost competitiveness concerns; Lazard estimates new SMRs could cost about $214 per megawatt-hour, and Antares has not disclosed pricing.

NUVIEW designs and prototypes space-based Light Detection and Ranging (LiDAR) payloads to enable high-resolution, 3D Earth observation from orbit. The company is using the latest Department of Defense NSIC award to rapidly prototype an upgraded LiDAR payload as it works toward its inaugural commercial space-based LiDAR system. That initial payload is intended to become the foundation for a planned satellite constellation offering persistent, high-resolution three-dimensional data. NUVIEW says its data will serve civil agencies, commercial enterprises, and defense organizations worldwide. The $5 million NSIC award builds on prior NSIC funding and is positioned to advance national security, economic competitiveness, and environmental resilience capabilities. CEO Clint Graumann described the award as an inflection point for the company and for U.S. commercial space-based LiDAR capabilities. Nuview develops space-based light detection and ranging (lidar) systems intended to map the entire landmass of Earth at centimeter-level resolution on an annual cadence. The company emerged from stealth in May and plans a constellation of about 20 lidar satellites to achieve its mapping goals. Nuview says it has made progress on addressing the size, weight and cost challenges of lidar systems in space. Financially, the company has raised $15 million so far (a $3 million seed and an in-progress Series A with $12 million closed to date). Nuview also reports it has secured over a billion dollars in early adopter agreements, though that revenue depends on delivering to spec. Clint Graumann is CEO and co-founder and has commented on the company’s environmental mission and technology progress. The company is actively building toward its stated deployment and commercial targets.
