Tawana Sizemore serves as a key procurement professional within the Defense Logistics Agency Aviation at Huntsville, supporting the sustainment and modernization of U.S. military aviation systems. Responsible for managing complex acquisition programs, she ensures the timely delivery of mission-critical components for aircraft, missile, and space propulsion platforms. Her work directly enables operational readiness by securing high-integrity avionics, power systems, and auxiliary equipment essential to national defense. She routinely handles sole-source and competitive procurements under FAR and DFARS guidelines, with a focus on technical specifications requiring stringent quality assurance and supply chain integrity. Sizemore maintains strong, long-term relationships with leading defense contractors including Intuitive Research and Technology Corporation, Aerospace & Commercial Technologies, LLC, BAE Systems Land and Armaments L.P., Simulation Technologies, Inc., and L3Harris Fuzing and Ordnance Systems, Inc. These partnerships are characterized by deep technical collaboration, with vendors providing specialized engineering support for classified and non-classified aviation hardware. Her contracting approach emphasizes performance-based outcomes, technical validation, and lifecycle sustainment, fostering trust with industry partners who deliver precision-engineered solutions under tight operational timelines. Her procurement portfolio reflects a strict preference for open competition, with 100% of awards issued without socioeconomic set-asides. This indicates a focus on technical capability and mission necessity over socioeconomic criteria, aligning with the agency’s priority to secure the highest-performing solutions for critical aviation systems. While small business participation is not formally incentivized through set-asides, vendors of all sizes compete on technical merit and proven performance. Sizemore’s primary procurement focus lies in NAICS 336413, encompassing other aircraft parts and auxiliary equipment, with secondary emphasis on aircraft engine components (336412) and electronic subsystems (334419). She specializes in procuring flight-critical hardware including avionics interfaces, thermal management units, and propulsion control systems, demonstrating deep expertise in aerospace manufacturing standards and defense supply chain resilience.
