About Kastellum Group, LLC

Written by GovTribe AI ·

Kastellum Group, LLC, a service-disabled veteran-owned small business based in Odessa, Florida, holds positions on three major federal IDIQs as a prime contractor and delivers cybersecurity, electromagnetic warfare, engineering, and intelligence services to the Department of the Navy and Department of the Air Force. The vendor splits evenly between prime (50%) and subcontractor (50%) roles, with prime work anchored to set-aside vehicles reserved for small businesses and service-disabled veteran-owned small businesses.

Kastellum's prime footprint centers on three indefinite-delivery vehicles awarded by the General Services Administration and Naval Sea Systems Command. The vendor holds a Seaport-NXG multiple-award IDC with a $4 billion ceiling awarded January 2, 2025, enabling competition for Navy professional services task orders in intelligence planning, cybersecurity, electromagnetic warfare, engineering, technical analysis, and logistics across the Naval Sea Systems Command and other Navy SYSCOM partners through January 1, 2029. Kastellum also holds positions under the OASIS+ Service-Disabled Veteran-Owned Small Business IDIQ (awarded September 30, 2024, ceiling $999,999,999,999, performance through September 29, 2029) and the OASIS+ Total Small Business Set-Aside IDIQ (awarded December 19, 2024, ceiling $999,999,999,999, base period plus one five-year option through December 18, 2029). Recent task-order activity includes a $7.77 million delivery order issued April 13, 2026, by Air Mobility Command under the OASIS+ SDVOSB vehicle for CCJ5 security cooperation contractor support to USCENTCOM with completion targeted for April 12, 2030, and a $500 minimum-guarantee task order under Seaport-NXG awarded March 6, 2025.

Customer concentration is dominated by Navy and Air Force accounts. The Department of the Navy Naval Sea Systems Command anchors the potential-value ranking with a $4 billion combined value across two awards (the Seaport-NXG IDV and related task order), while the Department of the Air Force Air Mobility Command holds three awards carrying $7.8 million in combined potential value. The GSA Federal Acquisition Service and Air Force Headquarters District Washington each account for two awards; Fleet Cyber Command rounds out the active set. The ranking by count and potential value align closely, with Navy's IDV ceiling driving most of the dollar concentration.

In its subcontractor capacity, Kastellum supports Booz Allen Hamilton on cyber operations support and professional services work (with a modification dated April 15, 2024, adding $2.35 million) and supports Lukos, LLC on cybersecurity and electromagnetic warfare cell services for JCSE (Cyberspace and Electromagnetic Activities) under Air Force contract FA481421D0004. Service Contract Inventory data, which captures federal service contracts above the $150,000 threshold, reports Kastellum as a named subcontractor on four SCI records in FY2024 delivering approximately 5.0 FTEs to federal programs; this represents only the SCI-reportable portion of the vendor's subcontractor activity and does not reflect total enterprise revenue.

Activity has accelerated from one award in 2022 to four in 2024, though recent velocity slowed to one award in 2025 and one in 2026 (through April). The vendor's capability portfolio aligns with the top parent vehicles' scope: engineering services, research and development in physical and engineering sciences, and professional technical services dominate the category concentration. Kastellum maintains a named subsidiary, Liberty Services Group, certified as a small disadvantaged business and service-disabled veteran-owned business joint venture. The vendor's SBA certifications as both veteran-owned small business and service-disabled veteran-owned small business expire October 20, 2027.
