About the company
C5T Corporation, a service-disabled veteran-owned small business (SDVOSB) and woman-owned small business headquartered at Scott Air Force Base, Illinois, operates as a prime contractor (79% of recent awards) delivering mission assurance, portfolio management, and mobility system support services to the Department of the Air Force and civilian federal agencies under set-aside vehicles. The company is a Subchapter S corporation certified as both a veteran-owned small business and SDVOSB through June 28, 2027, and competes predominantly under SDVOSB and women-owned small business (WOSB) set-asides, with recent work concentrated on Air Mobility Command programs at its primary location.
C5T's capability portfolio centers on mission assurance coordination, chief operations officer support, component-level operational decision advantage (CODA) analysis, and single and coalition mobility system (SMS/CMS) support. Representative prime work includes a $6.09 million firm-fixed-price delivery order from Air Mobility Command under the OASIS+ SDVOSB IDIQ (awarded June 1, 2026, through September 30, 2030) for mission assurance support with a revised mission essential plan; a $3.7 million cost-plus-fixed-fee definitive contract from Air Mobility Command for CODA services (awarded September 26, 2023, completing September 30, 2026); a $43.8 million delivery order under the GSA Multiple Award Schedule from Air Mobility Command for SMS/CMS support (awarded July 14, 2023, through September 30, 2027, with FY2024 invoicing of $8.5 million across 34.4 FTEs and 71,478 contractor hours at a blended government-paid rate of $118.83 per hour); and a $16 million delivery order from Air Mobility Command under the OASIS SB IDIQ for Chief Operations Officer support and portfolio management (awarded October 1, 2022, through September 30, 2027, with FY2023 invoicing of $3.4 million at approximately $100.82 per hour and FY2024 invoicing of $3 million at $101.74 per hour).
Customer concentration sits with the Department of the Air Force and its subordinate commands. Air Mobility Command anchors the portfolio with 12 awards (combined potential value $57.1 million) and represents the principal operational customer; the broader Department of the Air Force carries 4 awards ($47.3 million combined potential), and the Air Force Materiel Command Research Laboratory holds 4 awards ($4.8 million combined). The GSA Federal Acquisition Service appears second by award count (9 awards) but dominates by potential value at $5.03 billion, reflecting C5T's recent seat on multiple GSA government-wide vehicles. The Department of Defense United States Transportation Command places 4 awards ($25.3 million combined potential). NASA accounts for one award — the $20 billion SEWP VI GWAC ceiling — which inflates the top-customer potential-value ranking despite a single vehicle award.
C5T holds six government-wide acquisition contracts and agency-wide vehicles: the SEWP VI GWAC from NASA (multiple award, total small business set-aside, ceiling $20 billion, through October 31, 2036, awarded November 1, 2026); the OASIS+ SDVOSB IDIQ from GSA (multiple award, $999,999,999,999 placeholder ceiling, through April 15, 2030, awarded April 16, 2025, with one visible task order of $6.1 million); the OASIS+ Women-Owned Small Business IDIQ from GSA (multiple award, placeholder ceiling, through June 11, 2030, awarded June 12, 2025); the OASIS+ Total Small Business Set-Aside IDIQ from GSA (multiple award, placeholder ceiling, through April 14, 2030, awarded April 15, 2025); the OASIS SB IDIQ (one visible task order of $16 million); a GSA Federal Supply Schedule contract (ceiling $475,000, through August 23, 2031, awarded August 24, 2026); and six task orders under Alliant II and two under an indefinite-delivery contract HTC71125DE120. The Multiple Award Schedule carries 5 task orders with combined potential value of $87.5 million.
Award activity accelerated in 2025 (9 awards) and 2026 (6 awards, most recent November 1, 2026) after a lower-velocity period in 2022–2023 (1–2 awards per year). Two awards with combined potential value of $59.8 million complete within the next twenty-four months and face recompete exposure.
On SCI-reportable service contracts, C5T invoiced $19.1 million in prime-contract revenue across FY2022–FY2025, with FY2024 showing the largest activity at $11.5 million across 48.6 FTEs. The SCI dataset shows roughly 27.2 FTEs delivered to the federal government in FY2024, scaling down from 21.9 FTEs in FY2022. Government-paid hourly rates on federal services contracts span a median of approximately $107.44 per hour, with senior labor pricing through the 90th percentile at $117.13 per hour. Across SCI-reportable prime contracts, C5T subcontracted an average of 30 percent of contractor hours to a named pool of 11 subcontractors, indicating a mixed delivery model relying on internal capacity supplemented by specialty subs. Recent sub work under ECS Federal and CACI Inc. includes Global Air and Transportation Execution System support, Joint Transportation Management System implementation and infrastructure accreditation, and government-wide IT solution delivery.
C5T operates two named subsidiaries: Lodestar Government Solutions LLC (self-certified small disadvantaged business, SDVOSB) and C5T Cyberdata Alliance JV, LLC (SDVOSB joint venture). The NAICS portfolio centers on Computer Systems Design Services and Research and Development in the Physical, Engineering, and Life Sciences (10 awards each), with secondary depth in Administrative Management and General Management Consulting Services (6 awards) and Engineering Services (4 awards).
