Smack Technologies develops military AI systems, including Omega, a decision-support platform that uses reinforcement learning and real-time computer vision to accelerate targeting and repair disrupted battle plans. The company is also building Alpha, a forearm-mounted AI display intended to replace improvised field whiteboards, and is targeting 10–20 prototype units in the next six months. Smack has secured prototyping contracts from the Joint Fires Network and the Marine Corps Warfighting Lab, jointly worth more than seven figures. It operates an Austin, Texas office focused on hardware development and has scaled headcount from 19 in April to 51, aiming for about 85 by year-end. Recent funding (a $61M Series B) is being used to expand Omega production, advance Alpha development and grow the team.

Valar Atomics is developing advanced nuclear reactors intended for scalable deployment and is pursuing clusters of small reactors—sometimes called "gigasites"—to serve high-demand users such as data centers and manufacturing. Founded in 2023 and based in California, the company is also exploring applications beyond grid electricity, including producing synthetic fuels and supplying industrial heat. Its technology and commercial approach target energy-intensive industries and the growing electricity needs driven by AI infrastructure. Financially, Valar recently raised approximately $450 million (about $340 million equity and $110 million debt) at a reported $2 billion valuation, following a prior $130 million raise in 2025. The company is backed by defense-tech investors including Palmer Luckey and Shyam Sankar.

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.
