Rex Shearin

Rex Shearin serves as a key procurement lead within the FA8509 Aflcmc Wiuka, a specialized unit of the Department of the Air Force responsible for sustaining and modernizing mission-critical aircraft systems. He manages acquisitions focused on advanced avionics integration, auxiliary aircraft equipment, and specialized hardware for combat, transport, and polar mission platforms. His work directly supports the agency’s mission to enhance aircraft readiness and operational survivability through engineering-driven upgrades and rapid prototyping of mission-essential components. Shearin handles complex, technically demanding contracts requiring deep domain expertise in aerospace systems and compliance with stringent DoD acquisition regulations. While specific contractor names are not publicly disclosed, Shearin maintains a balanced procurement approach, engaging both large defense primes and agile small businesses capable of delivering precision-manufactured avionics components and mission-specific subsystems. His contracting patterns reflect a collaborative, performance-based relationship model, emphasizing technical validation, rapid iteration, and supply chain resilience. Vendor partnerships are typically structured around long-term Indefinite-Delivery, Indefinite-Quantity (IDIQ) vehicles and competitive small business set-asides to ensure innovation and responsiveness. Shearin consistently prioritizes small business participation, with half of all procurements designated as Total Small Business Set-Asides under FAR 19.5, reflecting a strong institutional commitment to socioeconomic contracting. His portfolio frequently supports 8(a), HUBZone, and SDVOSB firms with proven capabilities in aerospace manufacturing, demonstrating a deliberate strategy to diversify the supplier base and foster next-generation defense industrial capacity. His primary procurement focus is exclusively under NAICS 336413—Other Aircraft Parts and Auxiliary Equipment Manufacturing—encompassing specialized avionics enclosures, mission computer interfaces, environmental control units, and custom wiring harnesses for high-reliability aircraft platforms. This technical specialization underscores his expertise in procurement of embedded systems and mission-critical hardware requiring MIL-STD and DO-160 compliance.
