Sarah R. Jimmerson

Sarah R. Jimmerson serves as a Contract Specialist within the W6QK Acc-rsa under the Department of the Army, where she plays a pivotal role in executing complex acquisitions to sustain and modernize the Army’s aerial and missile defense capabilities. She manages the full lifecycle of contracts for mission-critical aerospace systems, including components for the UH-60 and AH-64 Apache platforms, as well as avionics, propulsion subsystems, and sensor integration services. Her work directly supports the agency’s strategic priorities in enhancing battlefield air defense and ensuring operational readiness through reliable, high-performance aerospace technologies. Jimmerson specializes in negotiated procurements under FAR Part 15, frequently handling requirements for both new development and sustainment of legacy systems. Jimmerson maintains collaborative relationships with a diverse base of aerospace contractors, including Tier 1 defense primes and specialized subsystem manufacturers. Her procurement approach emphasizes technical rigor and performance-based contracting, ensuring vendors meet stringent military specifications for reliability, interoperability, and lifecycle support. While no single contractor dominates her portfolio, she consistently engages firms with proven expertise in military-grade aircraft components and air transportation support services, fostering long-term partnerships grounded in compliance and mission alignment. Jimmerson’s contracting patterns reflect a strong preference for open competition, with 100% of her acquisitions conducted without set-aside designations. This approach underscores a strategic focus on maximizing technical capability and industrial base breadth rather than socioeconomic categorization, though she remains compliant with all federal small business participation requirements. Her portfolio does not prioritize 8(a), HUBZone, or SDVOSB set-asides, but she ensures all vendors—regardless of size—are evaluated on technical merit and past performance. Her primary procurement focus lies in NAICS 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing) and 488190 (Other Support Activities for Air Transportation), reflecting deep expertise in sourcing specialized aerospace components and technical maintenance services. She routinely procures flight control systems, mission computer interfaces, engine support hardware, and ground-based avionics testing equipment, demonstrating a technical command of Army aviation sustainment requirements.
