Caci Nss, LLC

Caci Nss, LLC, a subsidiary of CACI International Inc., delivers systems engineering, software support, and network modernization services to the Department of Defense and federal civilian agencies as a prime contractor on full-and-open and set-aside-free procurements. Headquartered in Reston, Virginia, Caci Nss operates as a large business with no SBA designations, competing on general contract vehicles and indefinite delivery awards rather than small-business set-asides.

Caci Nss's capability portfolio centers on integrated broadcast system (IBS) sustainment and modernization — a critical networked audio and video distribution platform for Air Force command communications — alongside professional services, IT solutions, and systems engineering for defense and federal civilian missions. Representative prime work includes a $1.128 billion cost-plus-award-fee delivery order from Army Special Operations Command (issued September 2021 under OASIS) for special operations forces emerging threats operations and planning support at Fort Liberty, North Carolina; a $225.9 million cost-plus-award-fee delivery order from Army Southern Command (September 2024 under OASIS) for integrated professional services performed in Doral, Florida; and a $1.022 billion cost-plus-award-fee delivery order from the Defense Threat Reduction Agency (June 2023 under OASIS) for professional and analytical services supporting countering and deterrence of weapons of mass destruction at Fort Belvoir, Virginia. On the Air Force side, Caci Nss holds a $135.5 million single-award indefinite delivery contract with the Warner Robins Air Logistics Complex for IBS-NS sustainment and modernization effective through August 2030, with five delivery orders totaling approximately $14.1 million issued as of the contract award date in August 2025.

Customer concentration is diffuse across defense and civilian agencies. The top five funding agencies by award count account for 48% of awards: the Department of the Navy Information Warfare Systems Command (181 awards, $1.79 billion combined potential value), the Department of Agriculture Forest Service Washington Office Acquisitions (165 awards, $54.2 million), United States Special Operations Command (144 awards, $1.34 billion), the Department of the Air Force Air Mobility Command (54 awards, $122.6 million), and the Department of Homeland Security US Coast Guard (36 awards, $7.4 million). The top five customers by potential value cover 46% of combined potential value and show a different composition: the Department of Homeland Security Office of the Chief Information Officer (12 awards, $22.39 billion), the Department of the Air Force Air Education and Training Command (19 awards, $9.99 billion), the GSA Federal Acquisition Service (14 awards, $4.29 billion), the Navy Information Warfare Systems Command (181 awards, $1.79 billion), and United States Special Operations Command (144 awards, $1.34 billion). This split reflects large-dollar awards concentrated in DHS and Air Force modernization efforts alongside high-volume Navy and SOCOM sustainment work.

Caci Nss operates from multiple parent vehicles. The Federal Supply Schedule GS35F5396H hosts 227 task orders worth $718.7 million combined potential value. The company holds several Navy indefinite delivery contracts: N6523611D4805 (165 task orders, $112 million), N6523616D8011 (62 task orders, $127.5 million), and others. The H9222211D0008 indefinite delivery vehicle carries 100 task orders for $334.6 million. A blanket purchase agreement under the GSA schedule (GS35F5396H-AG7604B130002) supports 164 task orders worth $53.2 million. OASIS participation underpins several of Caci Nss's largest awards, including the Army Special Operations Command, Army Southern Command, and Defense Threat Reduction Agency delivery orders cited above.

Activity across the portfolio spans 1,210 awards with a combined potential value of $87.16 billion, though the company obligated only $8.42 billion (10% of potential value) across all awards. Recent trajectory shows awards in 2022–2026 at low single digits annually (3, 5, 4, 6, 1 awards respectively), reflecting a shift toward larger-value indefinite delivery and delivery-order work rather than high-volume task-order placement. Nine awards face ultimate completion within the next twenty-four months, carrying combined potential value of $2.3 billion and representing a material recompete cliff.

On federal service contracts captured in the Service Contract Inventory, Caci Nss reported $790.9 million in invoiced revenue across three fiscal years (FY2022–FY2024): $220.6 million in FY2022 across 505 FTEs, $325.8 million in FY2023 across 889 FTEs, and $244.5 million in FY2024 across 580 FTEs. These figures are strict subsets of federal service contract activity above the $150,000 reporting threshold and exclude goods, classified work, and non-federal revenue. Government-paid hourly rates on SCI-reportable prime contracts ranged from a 10th percentile of $103.17 per hour through a median of $140.10 per hour to a 90th percentile of $213.41 per hour, positioning the vendor in the mid-range for federal professional services. Across SCI-reportable prime contracts, Caci Nss engaged 320 named subcontractors, routing approximately 17% of contractor hours to subs; this teaming posture reflects use of subcontractors for specialized IT services, cybersecurity, software maintenance, and small-business participation (women-owned, veteran-owned, service-disabled veteran-owned) rather than a dominant sub-reliance strategy.

Named subcontract work is minimal in the source: a single award as a named subcontractor to Serco-Ips Corporation in January 2022 for incremental funding of services. This reflects Caci Nss's positioning as a prime contractor across the vast majority of its federal footprint. The portfolio is dominated by IT and telecommunications services (NAICS Other Computer Related Services, 382 awards; Engineering Services, 302 awards; Computer Systems Design Services, 99 awards) and maintenance and repair of communications and detection equipment (PSC 234 awards), with smaller pockets of administrative management consulting and aircraft parts manufacturing.
