Reuter-Stokes, LLC

Reuter-Stokes, LLC (doing business as Reuter-Stokes Inc.), a General Electric Company subsidiary based in Twinsburg, Ohio, manufactures specialized radiation detection equipment — primarily Helium-3 proportional counters for neutron detection — sold to federal defense and national security agencies on a full-and-open, sole-source basis with no set-aside designation. The vendor operates almost exclusively as a prime contractor (97% of recent awards) and competes on technical uniqueness rather than small-business status; across seventy-eight awards since the early 1980s, Reuter-Stokes has not pursued SBA certifications and receives sole-source awards under FAR 13.106-1(b) due to being the only qualified source for specialized He-3 proportional counter manufacturing.

The vendor's portfolio centers on COTS and custom radiation detection components for nuclear nonproliferation, national security, and weapons-effects assessment missions. Representative recent prime work includes a $1.88 million firm-fixed-price purchase order from Naval Information Warfare Systems Command (September 2023) for 1,193 and 48 He-3 proportional counters; a $375 thousand NAVWAR order (September 2025) for He-3 proportional counters supporting RADIAC projects with performance in San Diego, California; and a $125 thousand Air Mobility Command purchase order (June 2024) for 72 He-3 proportional counters in support of a vehicle-mounted radiation detection system. These orders span single-unit costs ranging from roughly $13,000 to $1.88 million in aggregate contract value.

Customer concentration is heavy in defense and national security agencies. The top five customers by award count cover 56% of recent awards, led by Naval Information Warfare Systems Command (14 awards, $4.8 million combined potential value), the National Institute of Standards and Technology (9 awards, $5 million), and the Department of Energy National Nuclear Security Administration (8 awards, $12.2 million). By dollar potential, the NNSA dominates — claiming $12.2 million across eight awards — but NIST and NAVWAR round out the top tier. Across all seventy-eight awards, Reuter-Stokes has served twenty distinct federal customer agencies, including the Department of the Navy, the Air Force, DTRA, and NASA.

The vendor places task orders under an NNSA indefinite-delivery contract (DENA0001037) carrying seven task orders valued at $6.1 million, and subordinate work under NASA and Air Force IDIQs. Recent subcontract activity is minimal (3% of awards, two subs) — both supporting Johns Hopkins University Applied Physics Laboratory on DragonFly Extended Phase B flight-parts work under the NASA ARDES II vehicle (80MSFC20D0004). Activity has held steady at two to five awards annually over the past five years, with combined potential value of $23.7 million across all awards and $17.3 million obligated to date (73% realization). Primary NAICS concentration sits in Other Measuring and Controlling Device Manufacturing (334519) and analytical laboratory instrument manufacturing, with PSC classification dominated by Hazard-Detecting Instruments and Apparatus.
