Trideum Corporation

Trideum Corporation, a small-business Subchapter S corporation headquartered in Huntsville, Alabama, delivers modeling, simulation, test and evaluation, and cybersecurity engineering services to the Department of Defense as a prime contractor on 70 awards (58% of recent activity) and as a subcontractor on 51 awards (42%), with competitive posture across full-and-open and total small business set-aside vehicles.

Trideum's capability portfolio centers on distributed live-virtual-constructive simulation infrastructure, cyber risk analysis and modeling, test and evaluation systems, training systems development, and advanced engineering integration for Army modernization, Navy platform sustainment, and Air Force research programs. The company's recent prime work includes a $31.3 million cost-plus-fixed-fee delivery order from the Army's Program Executive Office for Simulation, Training and Instrumentation (awarded September 2025) for developing and integrating advanced D-LVC simulations and operational test infrastructure to support defeat-options testing; a $21.6 million firm-fixed-price definitive contract from the Army's Center for Army Analysis (awarded April 2026) for modeling and simulation support to the Army Modeling and Simulation Office, structured under the Department of Defense Employee Stock Ownership Plan Pilot Program; and a $19.2 million total small business set-aside cost-plus-fixed-fee delivery order under the CRAMSETS (Cyber Risk, Analysis, Modeling, Simulation, Evaluation and Testing Support) IDIQ (awarded September 2025) for cyber security and simulation testing at Redstone Arsenal. Trideum holds significant SBIR Phase II and Phase III awards in artificial intelligence and machine learning research, including a $1.9 million Phase II contract from the Army (awarded April 2024) for AI/ML technology development and a $239,887 Naval Sea Systems Command Phase I award for Space-Based Infrared System High research.

Customer concentration is heavily weighted to the Department of the Army, which accounts for the largest share of award count and potential value across Army Materiel Command, Training and Doctrine Command, PEO Simulation Training and Instrumentation, and Installation Management Command. By potential value, the Air Force dominates through its $46 billion Eglin Wide Agile Acquisition Contract (EWAAC) award (fourth on-ramp, issued March 2025), and the General Services Administration through two OASIS+ vehicle awards totaling $10.02 billion in ceiling value. The Navy contributes $4 billion through the Seaport Next Generation contract (January 2025). These three agencies account for 97% of combined potential value across the award portfolio, though the vast majority represents vehicle ceilings rather than task-order dollars currently obligated.

Trideum holds four strategic indefinite-delivery vehicles: two OASIS+ contracts with the General Services Administration ($999.999 billion ceiling each, one total small business set-aside awarded December 2024, one unrestricted awarded December 2024, both running through December 2029); a Seaport-NXG contract from Naval Sea Systems Command ($4 billion ceiling, awarded January 2025, through January 2029); and the Eglin Wide Agile Acquisition Contract with the Air Force ($46 billion ceiling, fourth on-ramp awarded March 2025, through September 2031). At the Army level, Trideum holds a single-award CRAMSETS IDIQ for cyber risk and testing support ($98.2 million ceiling, awarded September 2024, through September 2029, total small business set-aside) and a single-award SCARS (Simulator Common Architecture Requirements and Standards) SBIR Phase III contract ($80.4 million ceiling, awarded September 2024, through September 2029). These vehicles position Trideum to compete for task orders across civilian and defense agencies for engineering, program management, research and development, and technical services. Trideum also holds a GSA Multiple Award Schedule contract ($4 million ceiling, awarded May 2023) with 21 labor categories spanning entry-level engineer positions at $52.36 per hour through senior program manager roles at $256.52 per hour, with no security-cleared labor offered.

Activity has grown substantially—two awards in 2022 rising to thirty in 2024 and twenty-six in 2025—though the rate of new awards has moderated in 2026 (two awards to date). Four awards carrying combined potential value of $46.6 million face ultimate completion within the next twenty-four months, creating near-term recompete exposure, particularly in training systems and JBSA mission training complex work. Across SCI-reportable service contracts (a subset covering invoiced amounts above $150,000 threshold), Trideum reported $27.3 million in invoiced revenue from prime contracts across FY2022–FY2024, with roughly 50 FTEs delivering services in FY2024. Government-paid hourly rates on SCI prime contracts median around $66.57 per hour, with the 90th percentile reaching $143.99 per hour, reflecting a mix of technical specialists and senior program management roles. Across SCI-reportable prime contracts, subcontractors account for an average of 16% of total contractor hours, with twelve named subcontractors reported across the portfolio, indicating Trideum builds most delivery teams internally while maintaining selective subcontractor engagement.

In its subcontractor role, Trideum supplies systems engineering, simulation and training technical support, and human-machine interface development to major defense primes. Named prime relationships include Torch Technologies (engineering support for weapons development and integration, including modeling, simulation, and guidance-systems R&D, awarded multiple times 2023–2025), Booz Allen Hamilton (training systems, simulation, and technical assistance across Emergent Threat Training and Readiness Capability and Army Reserve simulation support, awarded 2023–2025), General Atomics Aeronautical Systems (human-machine interface development and logistics support for the MQ-1C Gray Eagle unmanned aircraft system, awarded May 2025), Scientific Research Corporation (test capability development and administrative support for the Test Resource Management Center, awarded 2024–2026), and Northrop Grumman (engineering support for Joint Knowledge Online Division training systems, awarded January 2025). Across the sub award footprint, Trideum performs systems engineering, technical analysis, simulation and modeling, software development, and test support work—capabilities aligned with its prime portfolio but routed through larger contractor relationships.

By NAICS and PSC, Trideum's work concentrates in Engineering Services (56 awards), Research and Development in the Physical, Engineering, and Life Sciences (18 awards), and Other Scientific and Technical Consulting (9 awards). PSC concentration tracks to Support Professional Engineering/Technical (21 awards), Support Professional Program Management (13 awards), and R&D Defense Other Applied Research and Exploratory Development (4 awards), confirming the vendor's positioning as a technical and engineering services provider across modeling, simulation, and test disciplines.

Trideum provides solutions and services in the area of test and evaluation (T&E), systems engineering and program management, modeling and simulation, systems analysis, sensor technologies, and information technology.
