About Antares Nuclear, Inc.
Antares Nuclear, Inc., a small disadvantaged business headquartered in Torrance, California, develops advanced nuclear technology for defense and space applications as a prime contractor across nine recent federal awards, with 100% of its work flowing through the Air Force Research Laboratory, the Department of the Air Force, the Office of the Secretary of Defense, and NASA.
Antares Nuclear competes exclusively in small business set-asides—across its portfolio, all awards carry either Total Small Business or no set-aside designation, with the majority flowing through SBIR Phase I and Phase II channels. The vendor's concrete capability set centers on microreactor systems, nuclear electric propulsion, power conversion equipment, space-based nuclear power platforms, and thermal management hardware for military and space logistics. Representative work includes a $4.2 million firm fixed-price definitive contract from the Air Force Research Laboratory awarded January 30, 2026, for nuclear electric propulsion to achieve dynamic space operations (NEPADSO), with place of performance in Long Beach, California and completion through May 1, 2028; a $1.23 million SBIR Phase II contract from AFRL for a space-based neutral particle beam system completing June 16, 2027; a $1.99 million Total Small Business set-aside definitive contract from AFRL for power conversion system development (reactor heat to electrical power), also completing January 30, 2028 with performance in Redondo Beach, California; and a $983,055 Other Transaction Agreement from the Office of the Secretary of Defense for the Advanced Nuclear Power for Installations (ANPI) program, completing August 12, 2027.
Customer concentration is extreme. The Air Force Research Laboratory anchors 6 awards worth $10 million of the vendor's $12.5 million combined potential value (80% of dollars). The Department of the Air Force places 1 award ($1.4 million), the Office of the Secretary of Defense places 1 award ($983 thousand), and NASA's Shared Services Center places 1 award ($148 thousand). The portfolio spans SBIR Phase I and Phase II vehicles, definitive contracts, purchase orders, and an OTA; four of the nine awards—worth $8.4 million combined potential value—reach ultimate completion within the next twenty-four months and therefore face recompete exposure. Work is categorized across Research and Development in the Physical, Engineering, and Life Sciences (8 awards) with sub-specialization in National Defense R&D Services covering applied research, experimental development, and basic research. The vendor operates as a 100% prime footprint with no recent subcontract activity. Activity has grown from one award in 2023 to three in both 2024 and 2025, with two awards so far in 2026; combined dollars obligated stand at $11.7 million, or 93% of potential value, indicating near-full funding realization across the portfolio.
