About the company
Caci Nss, LLC, a wholly owned subsidiary of CACI International Inc., is a large business prime contractor delivering networked communications infrastructure modernization, integrated professional services, and IT solutions to the Department of Defense and federal civilian agencies on full-and-open procurements with no set-aside designations. The vendor operates across 1,212 prime awards spanning nearly three decades, with a current footprint anchored in Air Force IBS-NS sustainment, defense threat-reduction analytics, and governmentwide professional services vehicles.
The vendor's capability portfolio centers on three concrete domains: integrated broadcast system (IBS) sustainment and modernization—the networked audio/video distribution backbone for Air Force command communications—deployed across a $135.5 million follow-on single-award indefinite delivery contract with the Warner Robins Air Logistics Complex (effective through August 2030) and a prior $104.4 million IBS vehicle; professional and analytical services supporting weapons of mass destruction deterrence and combatant command operations, exemplified by a $1.022 billion cost-plus-award-fee delivery order from the Defense Threat Reduction Agency under OASIS (running through December 2026, which generated SCI-reported invoicing of $110.9 million in FY2023, $146.6 million in FY2024, and $83.7 million in FY2025 across 702, 518, and 258 FTEs respectively); and integrated professional services for medical material enterprise support and personnel security operations. Recent civilian agency work includes a $225.9 million cost-plus-award-fee delivery order under OASIS for Army Southern Command through September 2029 (with subcontractors Serco Inc., Triple Canopy Inc., and Culmen International LLC supporting security and logistics functions), a $7.07 million delivery order from CDC Pittsburgh for Division of Laboratory Sciences information management under the CIO-SP3 GWAC (which invoiced $945 thousand in FY2025 across 5.4 self-performed FTEs), and a $6.28 million order from the Substance Abuse and Mental Health Services Administration for cloud-based financial planning and performance software via CIO-SP3, with Definitive Logic Corporation providing consulting labor.
Customer concentration by award count shows Navy Information Warfare Systems Command (181 awards, $1.79 billion combined potential value), Agriculture Forest Service Washington Office (165 awards, $54.2 million), and Special Operations Command (144 awards, $1.34 billion) dominating volume at 48% of recent awards, while by dollar value, the Homeland Security Office of the Chief Information Officer (12 awards, $22.39 billion), Air Force Air Education and Training Command (19 awards, $9.99 billion), and GSA Federal Acquisition Service (14 awards, $4.29 billion) anchor the largest single vehicles—a structural divergence signaling that many low-dollar Navy and SOCOM task orders contrast with fewer, multi-billion-dollar DHS and AETC vehicles. The vendor holds positions on five major parent vehicles: Federal Supply Schedule GS35F5396H (227 task orders, $718.7 million combined potential value), Indefinite Delivery Contract N6523611D4805 (165 task orders, $112 million), Blanket Purchase Agreement GS35F5396H-AG7604B130002 (164 task orders, $53.2 million), Indefinite Delivery Contract H9222211D0008 (100 task orders, $334.6 million), and Indefinite Delivery Contract N6523616D8011 (62 task orders, $127.5 million).
Activity has remained flat over five years (ranging from three to six awards per calendar year, 2022–2026), with eleven awards carrying combined potential value of $2.39 billion completing within the next twenty-four months, representing a material recompete exposure window. On SCI-reportable federal service contracts above $150,000, the vendor invoiced $965.3 million across FY2022 through FY2025 as a prime, with annual volume declining from $325.8 million in FY2023 (1,403 FTEs) to $174.4 million in FY2025 (537 FTEs), signaling contract consolidation or customer portfolio shift. Government-paid rates on federal services contracts range from a 10th percentile of $111.61 per hour to a median of $152.53 per hour and a 90th percentile of $208.99 per hour, consistent with mid-to-senior technical and analytical labor. Across SCI-reportable prime contracts, subcontractors executed 17% of total contractor hours, with 374 named subcontractors engaged over the reporting period; named subs on recent prime work include Dynamic Systems Inc. (woman-owned small business, software maintenance and warranty), Cyber Solutions & Services Inc. (woman-owned small business, IT services and cybersecurity on Defense Health Agency medical material enterprise support), and Techwerks LLC (service-disabled veteran-owned small business, training support). The vendor's top NAICS categories reflect this portfolio: Other Computer Related Services (382 awards), Engineering Services (304 awards), and Administrative Management and General Management Consulting Services (101 awards), with primary PSC coding around Maint/Repair/Rebuild of Communication/Detection Equipment (234 awards) and IT and Telecom services (229 awards combined).
