Parsons Government Services International Inc.

Parsons Government Services International Inc., doing business as Parsons, operates as a wholly-owned subsidiary of Parsons Corporation and serves as a prime contractor on federal weapons-of-mass-destruction threat reduction, nuclear nonproliferation, and international security programs issued by the Defense Threat Reduction Agency and the National Nuclear Security Administration, competing full-and-open with no set-aside designations. Parsons Government Services International Inc. is based in Pasadena, California and competes across the full federal landscape as a prime contractor only, with zero sub-award activity in recent federal records.

Parsons' federal capability footprint centers on design, integration, construction, communications, logistics, training, and equipment procurement for counter-nuclear-smuggling systems and chemical, biological, radiological, and nuclear (CBRN) threat reduction programs delivered to international partner nations. Representative prime work includes a $32.4 million delivery order from the National Nuclear Security Administration (July 27, 2026) for Middle East regional counter-nuclear-smuggling system deployment under the Counter Nuclear Smuggling System Deployment (CNSSD) IDIQ; a $27.6 million delivery order from the Defense Threat Reduction Agency (September 13, 2024) for facility, equipment, training, and sustainment services supporting the Eastern European Proliferation Prevention Program (E2P3) under the Cooperative Threat Reduction Integrating Contract (CTRIC); and a $20.9 million delivery order from NNSA (June 30, 2025) for Indo-Pacific counter-nuclear-smuggling system deployment services, again under CNSSD. These orders employ cost-plus-fixed-fee pricing across multiple geographic regions, with places of performance spanning Pasadena, the Middle East, Africa, Eastern Europe, the Indo-Pacific, and domestic program management sites.

Customer concentration is severe. The Defense Threat Reduction Agency dominates Parsons' portfolio, accounting for 34 awards (nearly 48% of total awards by count) valued at $5.05 billion in combined potential value — roughly 80% of the vendor's total award footprint. The National Nuclear Security Administration represents the second-largest customer with 8 awards totaling $1.11 billion. The top two agencies account for approximately 97% of combined potential value across Parsons' 71 prime awards. The Army Corps of Engineers Engineering District Middle East and Engineering Support Center Huntsville together represent $90.5 million across 14 awards, rounding out the active customer set.

Parsons holds two primary parent vehicles. The CTRIC IV indefinite-delivery contract (awarded August 21, 2025, by the Defense Threat Reduction Agency with a $3.5 billion ceiling through August 20, 2035) has generated 9 task orders. The Counter Nuclear Smuggling System Deployment (CNSSD) IDIQ (awarded April 1, 2024, by NNSA with a $1 billion ceiling through March 31, 2027) has generated 7 task orders valued at approximately $114 million combined. A third vehicle, Indefinite Delivery Contract HDTRA111D0008, carries 13 task orders and $226.3 million in combined potential value. Together, these three vehicles anchor most of Parsons' active work.

Activity has accelerated recently — 1 award in 2020, 2 in 2023, 7 in 2024, and 4 in 2025 — indicating organic growth in both CBRN threat-reduction and nuclear-smuggling detection programs. However, two awards with ultimate completion dates in the next twenty-four months carry a combined potential value of $37 million, creating near-term recompete exposure on CNSSD and CTRIC work.

Across SCI-reportable federal service contracts, Parsons invoiced $19.1 million in total across FY2022–FY2025, with peak activity in FY2022 ($16.4 million across 43.3 FTEs), a sharp drop in FY2023 to zero invoicing, a recovery to $2.3 million in FY2025 across 5.6 FTEs. On federal services contracts captured in SCI, median government-paid hourly rates run around $158.98/hr, with senior labor pricing reaching $261.00/hr at the 90th percentile. Parsons self-performs most work: across SCI-reportable prime contracts, subcontractors account for an average of 12% of contractor hours, with 9 named subcontractors reported. Named subs include Safeware Inc., Physical Sciences Inc., Techtrans International Inc., Us21 Inc., Teledyne FLIR Defense Inc., and others supporting radiation detection, logistics, and specialized equipment procurement functions. On specific task orders, subcontractor teams have expanded — the Central Europe regional counter-nuclear-smuggling deployment order (September 20, 2024) engaged eight named subcontractors including Ukrainian Radiation Equipment, Gefest, Smart Defense LLC, and Planate Management Group LLC (a service-disabled veteran-owned small business) for equipment procurement, design services, and logistics.

Primary NAICS concentration runs to All Other Professional, Scientific, and Technical Services (48 awards), Commercial and Institutional Building Construction (11 awards), and Engineering Services (2 awards), reflecting the construction, logistics, and systems-integration scope of CBRN threat reduction and nuclear-smuggling detection work.
