Simventions Inc.

Simventions Inc., a small business headquartered in Fredericksburg, Virginia, provides systems engineering, software engineering, modeling and simulation, and research and development services to the Department of the Navy and defense agencies as a prime contractor on 91% of recent awards, competing predominantly on full-and-open contract vehicles rather than set-asides. The company operates as a Subchapter S Corporation with no formal SBA certifications noted in the source.

Simventions' customer concentration is extreme and Navy-centric. The top five funding agencies account for 87% of awards by count, but Naval Sea Systems Command (NAVSEA) alone dominates both metrics, holding 195 awards (69% of the prime portfolio) with $10.98 billion in combined potential value — roughly 91% of the company's total federal contract pipeline. The Navy's Information Warfare Systems Command follows distantly with $962 million across two awards, the United States Marine Corps with 15 awards valued at $65.6 million, and the Naval Air Systems Command Naval Air Warfare Center with 23 awards valued at $24.5 million. This concentration exposes the vendor to single-customer recompete risk; within the next twenty-four months, twelve awards valued at $163.2 million reach ultimate completion, predominantly NAVSEA delivery orders.

Simventions holds three significant parent vehicles anchoring its prime work. Under the Seaport Next Generation (Seaport-NXG) IDIQ, the company has placed 18 task orders valued at $405.2 million for tactical simulation, electronic warfare, and asymmetric automation engineering support. The vendor also carries a $32.2 million SBIR Phase III Labor indefinite delivery contract with NAVSEA (extending through December 2029) and holds a multi-agency seat on the OASIS+ Unrestricted government-wide multiple-award vehicle (awarded December 2024) with no specified ceiling, enabling task order competition across federal agencies. Most recently, Simventions was awarded a multiple-award vehicle under the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) contract by the Missile Defense Agency on December 29, 2025, with a $151 billion ceiling through December 2035, though an initial task order carries only $500 in ceiling value.

Capability work centers on data repository and visualization tools supporting Navy strategic planning, operational decision-making, and manpower analysis. Representative recent prime awards include a $98.5 million Seaport-NXG delivery order (March 2025) for Tomahawk cruise missile engineering support; a $70.9 million Seaport-NXG order (May 2024) for asymmetric and intelligent automation technical and engineering support; a $35.3 million SBIR Phase III delivery order (September 2025) for continued support of the Manpower, Personnel, and Training (MPT) Analysis Repository for Verification and Learning (MARVL) database and Mission Task Analysis Tool (MTAT) under the Marine Corps Systems Command; a $24.5 million definitive contract (March 2025) from the Office of Naval Research for Human and Autonomous Robotic Teaming (HART) research and development; and a $23.7 million DARPA SBIR Phase III definitive contract (December 2024) for the SmartKM program, developing advanced model management capabilities for kill-chain and mission-level simulation environments. The source also names multiple smaller delivery orders for TACSIM (Tactical Simulator) tool development, Cooperative Engagement Capability data repositories, and Modernization Master Plan (MMP) tracking systems. Simventions engages with subcontractor Systems Thinking & Solutions Inc. on the SmartKM Phase III engineering services component.

Activity has grown substantially. Awards per year moved from 8 in 2022 to 12 in 2023 to 29 in 2024, declining to 12 in 2025 and 3 in 2026 to date (reflecting the three-month snapshot). The combined potential value across all 283 awards (prime and sub) reaches $12.1 billion, with $748.9 million obligated — a 6% obligation rate typical of early-phase IDIQs and research contracts. Most work falls under engineering services (134 awards) and research and development (75 awards in physical/engineering sciences), with a secondary stream in defense R&D and professional engineering support.

SCI-reported federal service-contract invoicing totaled $151.8 million across FY2022–FY2024 ($42.5 million in FY2022, $49.9 million in FY2023, $59.5 million in FY2024), supporting roughly 200–270 FTEs annually on prime contracts captured in SCI. Across SCI-reportable prime contracts, subcontractors performed 29% of contractor hours, with 81 named subs engaged over the reporting period. Government-paid hourly rates on prime contracts ranged from around $74/hr at the 10th percentile to a median of $95.53/hr and $119/hr at the 90th percentile, reflecting a mix of technical and senior engineering labor. On the $77.3 million Electronic Warfare and Spectrum Operations (EWSO) Seaport-NXG delivery order, Simventions reported $7.4 million invoiced in FY2024 across 31.8 FTEs with seven named subcontractors performing 24% of hours at a blended rate of $111.57/hr, with FY2023 invoicing of $6.4 million across 29.2 FTEs at $105.04/hr.

In its subcontractor role, Simventions delivers cybersecurity systems engineering, weapons systems modeling and simulation, combat engineering services, and program management support to primes including Alexandria Insights, Inc. (Expeditionary Radars program management), HII Technical Solutions Corporation and HII Mission Technologies Corp (integrated training systems cybersecurity), Mantech TSG-2 Joint Venture (tactical simulation and maritime patrol aircraft RDT&E), General Dynamics Mission Systems and General Dynamics Information Technology (Littoral Combat Ship and special technologies integration), Technology Service Corp (sensor systems engineering and combat systems analysis), American Systems Corporation (multi-mission helicopter software support), and Atlantic Diving Supply, Inc. (autonomous robotic support kits and communications systems). The sub footprint represents 26 named awards across 2023–2025, supplementing Simventions' dominant prime position on Navy contracts.

SimVentions is a small defense contracting business performing in the disciplines of Systems Engineering, Software Engineering, Cybersecurity, Modeling & Simulation, training and program management support to Navy and Marine Corps customers.
