About the company
Zeno Power Systems Inc., a Seattle-based manufacturer of radioisotope power systems, operates exclusively as a prime contractor on federal defense and space programs, with no subcontract footprint. The company is a for-profit small business competing under full and open (non-set-aside) procurement, with recent awards concentrated in Small Business Innovation Research (SBIR) programs and advanced defense development vehicles.
Zeno's federal portfolio centers on converting heat from radioactive decay into electrical power for space-based and maritime defense applications. Representative work includes a $14.998 million SBIR Phase II definitive contract awarded by the Air Force Research Laboratory in August 2022 for radioisotope power system development to enable space domain awareness; a $14.481 million Other Transaction Agreement from the Office of the Secretary of Defense in September 2024 for the Distributed Energy Throughout the Seas (DEPTHS) program, completing September 29, 2026; and a $3.35 million Other Transaction Agreement also from OSD in September 2024 for the Low-Profile Electric-Propulsion Nuclear Satellite (LENS) program, completing September 30, 2026. In December 2025, Zeno was awarded a position on the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) multiple-award IDIQ (Missile Defense Agency) with a ceiling through December 28, 2035; a single $500 task order has been issued to date.
Customer concentration is balanced across defense constituencies. The Air Force Research Laboratory accounts for five awards worth $17.1 million combined potential value; the Office of the Secretary of Defense holds two awards worth $17.8 million; and the Missile Defense Agency holds two awards worth $500 combined potential value, covering 100% of recent awards. Activity is modest and consistent — one award in 2019, two in 2021, two in 2022, two in 2024, and two in 2025 — with $35 million combined potential value obligated at 100%. Three awards (combined potential value $32.8 million) reach ultimate completion inside the next twenty-four months, presenting significant recompete exposure. Work falls predominantly under NAICS 541712 (Research and Development in the Physical, Engineering, and Life Sciences), with PSC coding across National Defense R&D Services and Nuclear Reactors categories. Zeno holds no parent vehicles beyond SHIELD and competes full-and-open with no set-aside designation across its footprint.
