Site, L.L.C.

Site LLC, a veteran-owned sole proprietorship based in Fairfax, Virginia, delivers weapons-systems engineering, integration, and lifecycle-support services to the Department of the Navy as a subcontractor on defense prime contracts, with subsidiary prime work across smaller contract vehicles. The vendor structures as a limited liability company and competes across full-and-open federal procurements without formal SBA set-aside designation.

Site LLC's customer footprint concentrates entirely on naval acquisition programs. The Department of the Navy accounts for 14 of 16 recent awards (88% of award count), split across three operating commands: Naval Sea Systems Command (4 awards), Naval Air Systems Command Naval Air Warfare Center (4 awards), and Naval Air Systems Command (1 award), with the Department of the Air Force placing 1 award. By potential value, the Navy's Naval Sea Systems Command anchors the recorded pipeline at $5 thousand in combined potential value, though the obligated dollar figures ($6.3 million across all awards) suggest material work flowing through these vehicles at scale beyond potential-value reporting.

Site LLC operates predominantly as a subcontractor (7 of 16 awards, 44% of the footprint) to Science Applications International Corporation and Sabre Systems LLC on defense prime contracts. Under SAIC, Site LLC delivers engineering, development, and analysis support on the Tomahawk missile lifecycle modernization program (task order COBRA, awarded January 2026) and integrated multi-domain command-and-control technical support to the Navy's Tomahawk Weapon System Program (PMA280, awarded November 2025); a prior SAIC sub task (June 2025) covered engineering design, test and evaluation for Naval Air Systems Command's airborne threat simulation organization. Under Sabre Systems, Site LLC provides air platform stores integration systems engineering services in support of Naval aircraft weapon and store systems lifecycle activities (task order PSI AA11600, awarded August 2025). The vendor holds seats on SeaPort-e (2 task orders, $5 thousand combined potential value), Indefinite Delivery Contract N0042118D0017 (2 task orders), ASTRO, Information Analysis Center Multiple-Award Contract, and One Acquisition Solution for Integrated Services, with most recent activity concentrated in FY2025 through January 2026.

Capability portfolio centers on weapons-systems engineering, hardware integration, maritime and aircraft platform systems engineering, simulation and wargaming, test and evaluation, and acquisition support across the Navy's tactical and strategic missile and air-warfare portfolios. Work is categorized across engineering services (10 awards), defense research and development (2 awards), and management consulting (1 award), with the majority targeting operational systems development and professional engineering support. Service Contract Inventory data shows minimal SCI-reportable activity (1 record, 2.2 FTEs in FY2024 as a named subcontractor), indicating that Site LLC's federal work is predominantly task-order driven through defense prime vehicles rather than standalone service-contract procurement.
