What System Studies & Simulation, Inc does

System Studies & Simulation, Inc. (S³) is a privately held, woman-owned small business defense contractor incorporated in Alabama in 1991 and headquartered in Huntsville, AL. The company delivers programmatic and technical services — systems engineering, acquisition support, training, simulation, C4ISR, logistics, maintenance, and security assistance — to U.S. Military Services (Army, Air Force, Navy, Marines, National Guard), the Missile Defense Agency, U.S. Forest Service, Department of the Interior, Partner Nation militaries including the Saudi Arabian Ministry of National Guard, and select commercial aviation customers. S³ is led by CEO Jan Smith and operates a 950+ employee organization staffed at 85.4% by veterans, with branch offices across 15 U.S. states and OCONUS operations in Riyadh and other international locations.

S³ delivers through an Agile Engineering Division (AED) and four wholly-owned subsidiaries: Kachemak Bay Flying Services (KBFS), which provides FAA-certified aviation services; S3 International (S3I), the corporation's international delivery agent; S3 Arabia (S3A), the Riyadh-based MNG support entity; and Global Logistics Support Services (GLSS), the prime contractor on the $11.4B USAF Contract Field Teams program. The technology stack centers on C4ISR, simulation and modeling, avionics, propulsion, guidance, navigation and control, weapons science, and systems engineering, supported by ISO 9001:2015, AS9100D, DCAA-approved accounting, and Top Secret Facility Security Clearance.

Revenue is generated primarily through U.S. government IDIQ contract vehicles — ASTRO, GSA MAS (Schedule 47QRAA19D005Y through 2029), SeaPort-NxG, OASIS+, RS3, CFT, and EXPRESS — plus subcontractor relationships with primes such as Lockheed Martin, Northrop Grumman, CAE, Vinnell Arabia, and GDC ME. Pricing is contract-vehicle negotiated and not publicly disclosed; the go-to-market is enterprise field sales supported by dedicated key personnel per vehicle, targeting DoD, federal agencies, and partner-nation militaries through Foreign Military Sales.
