Systems & Technology Research LLC

Systems & Technology Research LLC, doing business as STR, is a for-profit limited liability company based in Woburn, Massachusetts that delivers advanced research, engineering, and software development for national security applications as a prime contractor across full-and-open defense research procurements, competing without set-aside restrictions on technical merit. STR operates across artificial intelligence, wireless communications, electronic warfare, autonomy, machine learning, sensor processing, and cybersecurity spanning air, ground, maritime, space, and cyber operational domains.

STR's recent activity reflects sustained growth in defense R&D engagement, with awards increasing from 19 in 2022 to 62 in 2024, though moderating to 26 in 2025 and 14 through July 2026. The company's combined federal award footprint totals $51.26 billion in potential value across 398 prime and sub awards. Thirty-two awards with combined potential value $569.7 million reach ultimate completion within the next twenty-four months, creating near-term recompete exposure. Over 80% of awards support NAICS 541715 and 541710 (Research and Development in Physical, Engineering, and Life Sciences), with PSC concentration in defense applied research and exploratory development.

Defense Advanced Research Projects Agency dominates the customer base by award count, with 122 awards and $794.6 million combined potential value, followed by Air Force Research Laboratory (105 awards, $393.5 million), Army Research Development and Engineering Command (39 awards, $61.4 million), Naval Air Warfare Center (35 awards, $40.5 million), and Office of Naval Research (26 awards, $145 million). The concentration diverges sharply on potential-value ranking: Department of the Air Force commands $47.18 billion combined potential value across 9 awards, anchored by a $151 billion SHIELD multiple-award IDIQ with Missile Defense Agency (awarded December 29, 2025) and an $80.55 million Air Force OTA issued January 30, 2024. Air Education and Training Command accounts for $1 billion across 2 awards, and Aeronautical Systems Center $902.3 million across 3 awards.

STR's vehicle portfolio reflects defense R&D penetration across both traditional IDIQs and OTA authority. Recent major vehicles include the SHIELD IDIQ ($151 billion ceiling, no delivery orders obligated to date), a $1 billion Air Force Cyber IDIQ (April 6, 2022), a $900 million Air Force Life Cycle Management Center Architecture and Integration IDIQ (December 9, 2022), a $249 million Joint Artificial Intelligence Center BOA for AI data readiness (March 11, 2022), and multiple DARPA OTA vehicles with ceilings ranging from $1.4 million to $12.5 million across programs including SCORPIONFISH, LELANTOS, ALBATROSS, SYNC, SOAP, and DAIRS. The company also holds a $249 million BOA with Office of the Secretary of Defense for AI data readiness, positioning STR as a strategic delivery vehicle for intelligence and defense AI infrastructure.

Recent definitive-contract and OTA work illustrates STR's applied-research and prototype specialization. In the past eighteen months, STR received a $96.3 million U.S. Cyber Command OTA for cyberspace platforms and information warfare effects prototyping (May 2026), a $53.7 million Joint All-Domain Warfighting Software Phase 3 contract from Washington Headquarters Service (May 2023), a $57.3 million Air Force Research Laboratory DENALI TA1A effort (December 2022), a $61.1 million DARPA research program (December 2022), a $57.5 million Naval Information Warfare Systems Command JANUS NEMO contract (November 2022), and a $30.6 million Office of the Secretary of Defense TINDERBOX OTA (June 2026). Smaller awards span sensor processing (Maritime Automated Ingestion for Scene-Aware Identification, $6.768 million), autonomy benchmarking (ASIMOV, $6.27 million), and cognitive security (Intrinsic Cognitive Security, $7.655 million).

STR operates as prime on 82% of awards and subcontracts on 18%. Across SCI-reportable prime contracts, sub-hours share data is not provided in the source; however, the sub-award roster shows STR regularly engages specialized research partners including Johns Hopkins University Applied Physics Laboratory (radar systems engineering, hardware, research support), Parsons Government Services (radar systems engineering, ISR support), American Electronic Warfare Associates (electronic warfare development), Vision Systems Inc. (multi-INT analysis, wargaming), Applied Research Solutions Inc. (mission autonomy R&D), and academic partners including Cornell University, Virginia Tech, and University of Illinois. STR also coordinates with niche suppliers including Pembroke Instruments (hyperspectral imaging), Aechelon Technology (visual simulation), and Stellant PST Corp./L3Harris (RF amplifiers), indicating a systems-integrator posture for R&D delivery.

The company receives sub-awards from defense primes across intelligence and sensor-system work. In recent sub activity (identified in the award roster), STR subcontracts to Seacorp for radar analysis and firmware updates on naval tactical data (May 2026), to Vision Systems Inc. for multi-INT analysis frameworks (December 2024, July 2025), to American Electronic Warfare Associates for AI agent development and electronic warfare systems (June 2024–September 2025), to Parsons Government Services for radar ISR support (March 2024–August 2024), and to Applied Research Solutions for mission autonomy R&D (February 2025–September 2024). These engagements signal STR's role as a technical contributor to larger prime contracts in battle management, electronic warfare, and ISR domains.

STR received one federal grant from Office of Naval Research for radio and optical techniques for ionospheric plasma irregularities localization (awarded July 1, 2025, completion February 29, 2028), indicating limited direct grant engagement relative to contract portfolio. Service Contract Inventory data captures only 6 records—all as named subcontractor with zero prime reportings—across FY2022–FY2025, totaling roughly 2.9 FTEs in FY2024 and FY2025. SCI represents a partial view excluding classified work, goods, and micro-purchases; the broader invoiced-revenue trajectory through federal service contracts above the reporting threshold is not detailed in the source.
