About the company
Johnson Service Group, Inc., a Subchapter S corporation based in Westmont, Illinois, operates exclusively as a subcontractor to larger federal primes, delivering facilities sustainment, aircraft maintenance training support, and environmental compliance services to Department of Defense and Department of the Army customers. The vendor holds no federal prime awards and no identified SBA designations in recent activity; all six awards in the source data are subcontracts placed by prime contractors.
Johnson Service Group's customer exposure is concentrated in defense and military operations. The Department of the Navy (Naval Sea Systems Command and Military Sealift Command combined) and the United States Marine Corps account for three of six recent subcontracts; the Department of the Army Installation Management Command accounts for one. The work spans facilities support, aircraft training, IT service management, and environmental and disposal liabilities tracking across a narrow customer set with no civilian agency exposure in the source data.
All recorded work flows through two prime contractors. Rivet Operations Company LLC anchors two subcontracts — a December 2025 facility sustainment and security services engagement at Pearl Harbor Naval Shipyard and Intermediate Maintenance Facility (PHNSY&IMF) and a November 2025 building maintenance services re-compete for Military Sealift Command operations in Norfolk, San Diego, and Pensacola. Vintun LLC holds three subcontracts: a July 2024 Army Enterprise Environmental and Disposal Liabilities support contract covering training, database management, and cost tracking; a January 2024 IT service management and ITIL process support engagement; and a February 2023 systems engineering support task for USMC wargaming. A February 2026 subcontract for pilot and maintenance training to support Vietnam T-6C aircraft training falls under a U.S. Air Force FMS case managed through prime contractor FA3002-25-P-0003.
The vendor shows minimal activity velocity — one award per year in 2023 and 2024, two in 2025, and one in early 2026. Combined potential value across all six awards stands at $635 thousand. Service Contract Inventory records capture 0.4 FTEs in FY2024 on a single SCI-reportable sub-engagement, indicating a very small federal footprint on SCI-reportable service contracts above the $150,000 threshold. Johnson Service Group operates as a feeder subcontractor with no identified parent vehicle presence, prime contracting capability, or growth trajectory in the source data. The vendor's role is to supply specialized labor (facilities, training, environmental compliance, IT services) to established defense primes rather than to hold or grow its own contract vehicles or customer relationships.
