Mary M. Zellmer

Mary M. Zellmer serves as a Contracting Officer within the FA8621 Aflcmc Wnsk Sims organization under the Department of the Air Force, where she manages complex acquisitions critical to sustaining and modernizing advanced aircrew training systems and integrated avionics infrastructure. Her portfolio centers on procuring mission-critical capabilities that enhance pilot and maintenance crew readiness through synthetic training environments, embedded logistics systems, and high-performance aircraft support technologies. Zellmer exercises full contracting authority across the acquisition lifecycle—from requirements validation and market research to solicitation, award, and contract administration—ensuring alignment with Air Force operational priorities and defense acquisition regulations. Her primary contractor relationship is with Lockheed Martin Corporation, with whom she collaborates on large-scale, technically demanding contracts involving simulation systems, avionics integration, and sustainment services for next-generation aircraft platforms. Zellmer’s procurement approach emphasizes performance-based outcomes, systems engineering rigor, and long-term lifecycle support, fostering strategic partnerships with industry leaders capable of delivering mission-critical capabilities under stringent security and technical standards. Zellmer’s contracting patterns reflect a 100% non-set-aside procurement strategy, with no utilization of 8(a), HUBZone, SDVOSB, or other socioeconomic programs. Her focus remains on securing the highest technical capability and operational readiness, prioritizing mission success over socioeconomic preferences. This approach aligns with the high-stakes, mission-essential nature of the systems she acquires, where performance and reliability are non-negotiable. Her primary NAICS code focus is 236210 (Industrial Building Construction), indicating a significant portion of her acquisitions involve facility modernization, specialized hangar construction, and infrastructure upgrades to support advanced training simulators and avionics test environments. While seemingly atypical for an aviation systems office, this reflects the physical infrastructure investments required to house and sustain cutting-edge synthetic training ecosystems. Zellmer’s expertise spans both technical systems procurement and the enabling physical infrastructure that ensures operational continuity.
