Argon ST, Inc.

Argon ST, Inc., a Boeing subsidiary headquartered in Fairfax, Virginia, manufactures advanced command, control, communications, computers, combat, intelligence, surveillance, and reconnaissance (C5ISR) electronic systems and components for the Department of the Navy as a prime contractor on firm fixed-price and cost-plus-fixed-fee delivery orders. The company operates without set-aside designations, competing full-and-open across defense electronics and defense systems manufacturing.

Argon ST's customer base concentrates overwhelmingly on naval programs. The Department of the Navy accounts for the vast majority of recent awards; the top five Navy-focused customers—Naval Supply Systems Command (525 awards, $123.3 million potential value), Naval Air Systems Command (29 awards, $587.5 million potential value), Naval Sea Systems Command (36 awards, $77.2 million potential value), Naval Air Warfare Center (10 awards, $99 million potential value), and the Office of Naval Research (11 awards, $1.41 billion potential value)—represent 76% of all awards by count and 93% of all potential value. The Office of Naval Research's $1.41 billion share, drawn from eleven awards, anchors the portfolio's dollar concentration; the potential-value ranking reveals a different concentration pattern than award-count ranking, with research and development vehicles dominating dollars while supply-and-logistics orders dominate volume.

Argon ST holds three major indefinite delivery vehicles with the Navy. A $463 million Indefinite Delivery Contract with Naval Air Systems Command (effective January 2023 through January 2028) funds Multi-Intelligence Sensor Development (MISD) sensor suite production unit components for manned and unmanned aircraft, particularly the P-8A Poseidon Multi-Mission Maritime Aircraft; over $70 million in task orders have been issued under this IDC for 10-channel common chassis systems, low-band suite hardware, interface communications equipment, and technical data packages. A $37.9 million Basic Ordering Agreement with Naval Supply Systems Command (effective September 2022 through September 2027) covers electronic components and systems including radio frequency amplifiers, antenna units, chassis systems, frequency converters, and digital equipment; NAVSUP has issued approximately $61.7 million in task orders against this ceiling through August 2025, indicating sustained utilization. A $3.4 million Basic Ordering Agreement with Naval Air Systems Command (effective August 2023 through August 2028) provides common chassis weapons replaceable assemblies, shop replaceable assemblies, and engineering services. Recent representative prime awards include a $14.97 million firm fixed-price delivery order from Naval Air Systems Command (December 2025) for MISD production low-band hardware supporting P-8A sustainment, a $6.32 million firm fixed-price order (December 2025) for a 10-channel common chassis, a $6.72 million cost-plus-fixed-fee contract from the Air Force Research Laboratory (November 2024) for Cyber Mission Assurance Technology research and development, and a $12.41 million cost-plus-fixed-fee definitive contract from the Defense Advanced Research Projects Agency (December 2022) for a DARPA research project.

Activity has grown from 14 awards in 2022 to 41 in 2025; the source data includes only one award in 2026 as of the March 2026 snapshot. Twenty awards with combined potential value of $116.1 million face ultimate completion within the next twenty-four months, representing recompete exposure. Argon ST's contract portfolio centers on bare printed circuit board manufacturing (180 awards), search, detection, navigation, guidance, and aeronautical system manufacturing (116 awards), and radio/television broadcasting and wireless communications equipment manufacturing (81 awards) by NAICS classification; miscellaneous communication equipment (197 awards) and electronic countermeasures equipment (157 awards) dominate by PSC code. The company's supply chain includes major subcontractors such as Digital Receiver Technology (cables and tuners), Syncom Electronics Corporation (cable assemblies), Caci Azure Summit Technology (RF switches and signal processors), Abaco Systems (VPX switches), Parker-Hannifin Corporation (chassis assemblies), Extreme Engineering Solutions (computing components), Amphenol Aerospace Operations (connectors), and Brandywine Communications (timing modules).

Across its subcontractor role in non-SCI federal work, Argon ST delivers RF hardware, antennas, amplifier assemblies, and related electronic components to Leidos (on signals-intelligence and sensor sustainment task orders), Northrop Grumman Systems Corporation (on engineering services and test/repair work), Lockheed Martin Corporation (on Littoral Combat Ship Freedom variant combat system sustainment), HII Mission Technologies Corp (on logistics and intelligence surveillance and reconnaissance equipment), and ManTech TSG-2 Joint Venture (on unmanned aircraft systems engineering). Service Contract Inventory reporting, which captures only federal service contracts above $150,000 and excludes products and goods, shows Argon ST appearing in seven SCI records as a named subcontractor (zero as prime) across FY2022–FY2024, with roughly 36.2 FTEs in FY2022 declining to 24.5 FTEs in FY2024; SCI is a strict subset of the company's federal services activity and a smaller subset of total enterprise revenue. Argon ST's substantial federal footprint—$2.47 billion in combined potential value across 1,180 awards, with $575.9 million obligated—reflects its established position as a critical supplier of specialized electronic components and sensor systems to naval maritime patrol, anti-submarine warfare, and intelligence, surveillance, and reconnaissance programs.
