Sean Koski

Sean Koski serves as a key procurement professional within the W4GG Hq US Army Tacom, supporting the lifecycle management and modernization of ground combat and support vehicle systems for the Department of Defense. Responsible for managing complex acquisition programs, he ensures the timely delivery of mission-critical technologies that enhance vehicle survivability, mobility, and power efficiency. His portfolio primarily encompasses analytical instrumentation, specialized manufacturing, and avionics integration for armored and tactical wheeled platforms, aligning with TACOM’s mandate to sustain and upgrade the Army’s ground vehicle fleet through integrated engineering and logistics support. Koski maintains consistent working relationships with a select group of defense contractors, including Schutt Industries, VAREC NV, ONTIC ENGINEERING & MANUFACTURING, INC, A&M AEROSTRUCTURES, INC., and BOWHEAD AVIONICS MANUFACTURING, LLC. These partnerships reflect a focus on high-precision manufacturing, electronic systems integration, and structural components for military vehicles. His contracting patterns indicate a preference for established defense suppliers with proven technical capabilities in ruggedized systems, often awarding contracts through competitive sealed bidding or limited-source mechanisms to ensure mission readiness and supply chain resilience. His procurement strategy prioritizes open competition, with 57.1% of awards issued without set-asides, while maintaining a meaningful commitment to small business participation—28.6% of contracts are awarded under Total Small Business Set-Asides, and 14.3% under 8(a) competed programs. This balance ensures access to innovative small firms while preserving flexibility for complex, high-risk technical requirements. Koski’s primary procurement focus lies in NAICS 334516 (Analytical Laboratory Instrument Manufacturing), reflecting deep engagement with diagnostic, testing, and calibration systems for vehicle subsystems. He also procures specialized apparel and accessories (315990) and technical publishing services (513130), indicating a broad operational support scope that includes soldier equipment and technical documentation essential to field maintenance and training. His expertise spans the intersection of mechanical engineering, avionics, and logistics sustainment within the armored vehicle domain.
