Elizabeth Stewart

Elizabeth Stewart supports the Naval Air Warfare Center Air Division in managing critical acquisitions for advanced naval aviation systems, ensuring the integration of next-generation avionics, electronic warfare suites, and mission-critical aircraft subsystems. She plays a pivotal role in executing the agency’s mission to sustain legacy platforms while accelerating the fielding of cutting-edge airborne technologies. Her procurement portfolio primarily encompasses research and development contracts, systems integration efforts, and technical services supporting airborne sensor modernization and communications infrastructure. She works closely with engineering and technical teams to translate operational requirements into compliant, performance-based solicitations that align with Navy aviation modernization priorities. Stewart maintains strong, long-standing relationships with key industry partners including SABRE SYSTEMS, LLC, The Boeing Company, SAIC, Systems Planning and Analysis, Inc., and ONTIC ENGINEERING & MANUFACTURING, INC. These partnerships reflect a balanced approach between large prime contractors with deep systems engineering capabilities and specialized mid-tier firms delivering niche components and technical services. Her contracting patterns emphasize performance-based outcomes, technical risk mitigation, and iterative development cycles, often utilizing Other Transaction Authority (OTA) and Indefinite-Delivery/Indefinite-Quantity (IDIQ) mechanisms to accelerate innovation. Her procurement strategy reflects a strong commitment to small business participation, with nearly half of her awards structured as total small business set-asides under FAR 19.5. While no single socioeconomic category dominates, her consistent use of small business set-asides demonstrates active support for competitive small business engagement across the aviation technology supply chain. Her primary NAICS focus lies in 511210 (Software Publishers), reflecting heavy investment in mission-critical software development for avionics and sensor systems. She also routinely procures components under 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing) and 334220 (Radio and Wireless Communications Equipment Manufacturing), underscoring expertise in airborne communication architectures, electronic warfare payloads, and embedded systems integration.
