Systems Integration / Modeling & Simulation, Inc.

Systems Integration / Modeling & Simulation, Inc., doing business as Systems Integration, is a minority-owned, self-certified small disadvantaged business based in Tullahoma, Tennessee, that delivers telecommunications support, security systems services, and IT infrastructure operations to the Department of Defense, primarily as a prime contractor (99% of recent awards) under Total Small Business set-asides and full-and-open vehicles. The vendor holds seats on multiple defense and civilian IDIQs, including the OASIS+ Small Business Multiple Award Contract (awarded December 2024 with a five-year term through December 2029) and agency-specific vehicles including the Army Cyber Command's Information Management Communications Services IV (IMCS IV) and Naval Sea Systems Command's single-award landline telecommunications support IDIQ.

The vendor's customer concentration centers overwhelmingly on Navy entities. Department of the Navy Naval Sea Systems Command dominates both award count and dollar value—14 awards carrying $87.84 billion in combined potential value, with most work routed through the SeaPort-e vehicle ($72.55 billion combined potential value across four task orders). The Department of the Army Cyber Command anchors the second-largest dollar position at $990 million across two awards, while the Navy's Information Warfare Systems Command places 14 smaller orders totaling $33.7 million. The Department of the Air Force (including Air Mobility Command and Air Education and Training Command) accounts for seven awards at $7.3 million combined value. Across top customer agencies, Systems Integration covers 67% of awards; the Navy's two commands alone represent 28 awards and roughly 99% of combined potential value. Recent representative work includes a $10.7 million Total Small Business delivery order from Naval Information Warfare Systems Command for alarm monitoring services through May 2027 under the GSA Multiple Award Schedule, $1.2 million in telecommunications support delivery orders from Naval Sea Systems Command at Tullahoma and Crane, Indiana (awarded March 2025 and March 2026) under the N0016423D1024 IDIQ, and a $2,500 delivery order from Army Cyber Command for infrastructure operations and maintenance support at Fort Huachuca under IMCS IV.

The vendor's capability portfolio centers on wired and wireless telecommunications support (nine NAICS awards), security systems services and alarm monitoring (17 NAICS awards), security guards and patrol services (13 NAICS awards), IT infrastructure engineering and operations (10 NAICS awards), and IT support and network management labor (eight awards across computer-related services, with ten PSC awards in telecommunications network management). GSA Schedule labor categories span 171 active positions priced from $62.21 per hour (Switchboard Operator I, high school education) through $491.02 per hour (Program Manager II, master's degree with 21 years' experience), with middle-tier technical roles including Cyber Security System Architect at $180.74 per hour and System Engineer III at $238.25 per hour. Security clearances are required across most labor categories.

Award activity shows limited recent placement (one award in 2026, one in 2025, three in 2024, four in 2023, one in 2022), driven primarily by the December 2024 OASIS+ SB award which carries a placeholder ceiling and the prior December 2023 SeaPort-e vehicle positioning. Within the next twenty-four months, three awards reach ultimate completion with combined potential value of $13 million, creating modest recompete exposure. Service Contract Inventory data shows minimal SCI footprint (three records, all as named subcontractor, covering FY2022–FY2024 only), with roughly 10–14 FTEs in subcontracted service delivery across those fiscal years—a limited view that excludes the vendor's larger prime service-contract portfolio. The vendor subcontracts to General Dynamics Information Technology on an Air Force Civil Engineer Control Systems Cybersecurity Initiative task, representing its only named sub-award in the source data.

As a mature company with two GSA schedules, SIM&S has significant experience supporting telecommunications and IT programs, administrative services efforts, and security services contracts for government and commercial entities.
