Blocker serves as a key procurement professional within the W6QK Acc-rsa, a critical component of the Department of the Army responsible for sustaining and modernizing aerial and missile defense systems. She manages the acquisition of mission-critical aerospace components and support services essential to platforms such as the UH-60 Black Hawk and AH-64 Apache, with a focus on avionics, propulsion systems, and sensor integration. Her work directly supports the Army’s strategic modernization priorities by ensuring timely delivery of reliable, high-performance technologies that enhance operational readiness. Blocker handles a diverse portfolio of contracts spanning engineering services, specialized manufacturing, and logistical support for air transportation systems. Blocker maintains collaborative relationships with a broad base of industrial partners, including firms specializing in power transformer manufacturing, aircraft engine component production, and aviation support services. While specific contractor names are not publicly disclosed, her contracting patterns reflect consistent engagement with both large defense contractors and specialized small businesses capable of delivering niche aerospace technologies. Her approach emphasizes technical compliance, supply chain resilience, and performance-based acquisition strategies to meet the demanding requirements of military aviation systems. Blocker demonstrates a strong commitment to socioeconomic contracting, with nearly half of her acquisitions set aside for small businesses under FAR 19.5. Her portfolio consistently prioritizes small business participation, aligning with Army initiatives to expand opportunities for disadvantaged and veteran-owned firms. Although no specific set-aside categories are dominant, her pattern indicates active inclusion of 8(a), HUBZone, and SDVOSB vendors where technical capabilities align with procurement needs. Her primary procurement focus centers on NAICS 335311 (power and specialty transformers), 488190 (air transportation support), and 336412 (aircraft engine parts), reflecting deep expertise in electrical systems, aviation logistics, and propulsion technology. She routinely procures mission-critical components such as motor-generators, current-carrying wiring devices, and specialized transformer assemblies that underpin the reliability of Army aviation platforms.
