About the company
William C. Brown, Inc., a veteran-owned small business based in Manassas, Virginia, holds three prime federal vehicle positions — a $151 billion Missile Defense Agency IDIQ for advanced defense systems integration, a GSA OASIS+ Total Small Business set-aside IDIQ, and a GSA Multiple Award Schedule contract — but has yet to generate material delivery-order activity or obligated dollars against these vehicles as of late 2025. The company is SBA certified as both a Veteran-Owned Small Business and a Service-Disabled Veteran-Owned Small Business (both certifications expiring March 24, 2029), structured as a Subchapter S corporation, and operates exclusively as a prime contractor with no subcontractor footprint in the tracked awards.
The MDA SHIELD contract, awarded December 29, 2025, represents William C. Brown's only defense prime vehicle. SHIELD is a ten-year, $151 billion multi-award IDIQ under full and open competition procuring integrated, multi-domain defense systems design, research and development, prototyping, systems engineering, weapon design, production, test and evaluation, and cybersecurity modernization across classified and unclassified programs. The initial delivery order (awarded same day as the IDV) carries a $500 ceiling, signaling a placeholder initial draw with anticipated scaling as operational requirements materialize. Work is performed in Huntsville, Alabama and other locations as specified in individual task orders.
On the civilian services side, William C. Brown holds a seat on GSA's OASIS+ Total Small Business IDIQ (awarded December 19, 2024), a $999,999,999,999 governmentwide vehicle reserved for small businesses and running through December 2029. OASIS+ spans seven functional domains — Management and Advisory, Technical and Engineering, Research and Development, Intelligence Services, Environmental Services, Facilities, and Logistics — with a $2,500 minimum guarantee and 0.15% Contract Access Fee. The vendor's GSA Multiple Award Schedule contract (awarded October 2021, ceiling $1 million, expires October 2026) supports IT labor across 15 categories ranging from $85.94 to $174.60 per hour, including network administration, systems engineering, software development, information assurance, and hardware engineering roles. Most positions require a bachelor's degree and 4 to 12 years of experience; senior systems engineer and integrator slots carry security-clearance requirements, while entry-level network administrator and information assurance engineer positions anchor the lower rate tier.
Customer concentration splits evenly by award count between GSA Federal Acquisition Service (2 awards, $1 million combined potential value) and the DOD Missile Defense Agency (2 awards, $500 combined potential value). However, the MDA SHIELD IDIQ's $151 billion ceiling dwarfs potential-value rankings — the vendor's total tracked combined potential value is $1 million across four awards, a reflection of early-stage vehicle positioning with minimal task-order activity to date. Service Contract Inventory records show one reported subcontractor engagement in FY2024 with 7.7 FTEs, though this appears to reflect older SCI data and does not align with the prime-only posture evident in current award tracking. Award activity has been sparse: one contract in 2021 (the MAS agreement), then a gap through 2023, followed by two awards in 2025 (OASIS+ SB IDIQ in December 2024 and SHIELD in December 2025). No obligated dollars have been recorded against any of the three vehicles, indicating William C. Brown remains in early deployment phase on all three vehicles as of late 2025.
