Lionel E. Nadeau

Lionel E. Nadeau serves as a Procurement Contracting Officer for the Missile Defense Agency (MDA), where he plays a pivotal role in executing strategic acquisitions that support the development and fielding of integrated missile defense systems. His responsibilities include managing the full lifecycle of complex contracts for technical consulting, systems integration, and operational support services critical to midcourse and terminal-phase interception capabilities. Nadeau ensures compliance with federal acquisition regulations while aligning procurement decisions with MDA’s mission to advance layered defense architectures through innovation and rapid prototyping. He maintains enduring relationships with prime contractors including Lockheed Martin Corp and Northrop Grumman Systems Corporation, partnering with these industry leaders to deliver advanced sensor systems, guidance technologies, and battle management software. His contracting patterns reflect a preference for large, experienced defense contractors capable of supporting high-stakes, technically demanding programs, while also engaging Jacobs Technology Inc. for logistics and systems engineering support. These partnerships are characterized by long-term collaboration on multi-year, performance-based contracts requiring stringent security and technical oversight. Nadeau’s procurement portfolio is overwhelmingly non-set-aside, with 90.9% of awards issued under full and open competition, reflecting the specialized nature of missile defense requirements. However, he consistently allocates 9.1% of opportunities to Total Small Business Set-Asides under FAR 19.5, demonstrating a measured but intentional commitment to small business participation where capability and capacity permit. His primary NAICS focus areas center on scientific and technical consulting services, particularly Administrative Management Consulting (541611), Process and Logistics Consulting (541614), and Human Resources Consulting (541612), alongside Research and Development in Engineering Sciences (541712). These reflect his expertise in procuring mission-critical support services that enable MDA’s systems engineering, test evaluation, and workforce development initiatives across the defense technology lifecycle.
