Sarah Cottrell, Contract Specialist

Sarah Cottrell serves as a Contract Specialist within the W6QK Acc-rsa, a critical acquisition node under the Department of the Army focused on sustaining and modernizing aerial and missile defense systems. She supports the full lifecycle procurement of mission-critical aerospace components and engineering services, with a primary emphasis on guided missile subsystems, avionics integration, and propulsion system upgrades for platforms such as the UH-60 Black Hawk and AH-64 Apache. Her role ensures alignment between technical requirements and contractual execution, facilitating timely delivery of high-reliability systems essential to national air and missile defense readiness. She routinely manages complex sole-source and competitive acquisitions under FAR Part 15 procedures, working closely with engineering and program management teams to validate technical specifications and performance metrics. Cottrell collaborates with a diverse ecosystem of defense contractors specializing in aerospace subsystems and systems engineering, including Tier 1 prime integrators and niche suppliers of missile guidance components, radar sensors, and flight control hardware. While no single contractor dominates her portfolio, she consistently engages with firms possessing ITAR compliance, AS9100 certification, and DoD 2167.1 accreditation. Her working relationships are characterized by technical rigor and early contractor involvement, ensuring manufacturability and sustainment readiness from the outset of acquisition planning. Cottrell’s contracting activity reflects a strict preference for open competition, with 100% of her acquisitions conducted under non-set-aside authorities. She does not routinely utilize 8(a), HUBZone, or SDVOSB set-asides, instead prioritizing technical capability and mission-critical performance over socioeconomic categorization. This approach ensures access to the most qualified industrial base capable of meeting stringent defense specifications, particularly for classified or export-controlled technologies. Her procurement focus is concentrated in NAICS 336419 for guided missile parts and auxiliary equipment manufacturing and NAICS 541330 for specialized engineering services. She routinely acquires precision-guided munition components, flight control computers, radar seeker assemblies, and mission-critical systems engineering support, demonstrating deep expertise in defense aerospace procurement and technical contract administration.
