C.Isha Arrington serves as a key procurement lead within the Defense Logistics Agency’s Columbus Division #3, responsible for securing mission-critical strategic materials essential to national defense systems. Focused on the acquisition of high-purity nonferrous metals, specialty chemicals, and engineered components for aerospace, electronics, and weapons platforms, Arrington manages complex technical contracts requiring stringent material specifications and supply chain integrity. Their work directly supports the agency’s mandate to ensure uninterrupted access to domestically sourced, defense-critical inputs, prioritizing reliability, purity, and compliance with DoD material standards. Arrington typically handles research-driven, high-specification procurements requiring deep technical evaluation and vendor qualification. Arrington maintains a primary contracting relationship with ARES STRATEGIC MINING, INC., a specialized vendor with demonstrated capability in sourcing and refining rare and strategic nonferrous materials. The partnership reflects a preference for contractors with vertically integrated supply chains, advanced metallurgical processing expertise, and proven compliance with defense material traceability requirements. This relationship is characterized by long-term, performance-based contract structures that emphasize consistent quality assurance and just-in-time delivery of mission-essential inputs. Arrington’s procurement portfolio reflects a strict preference for full and open competition, with 100% of awards issued under no set-aside categories. There is no formal reliance on 8(a), HUBZone, SDVOSB, or other socioeconomic programs; instead, selections are driven exclusively by technical capability, material purity certifications, and supply chain resilience. This approach underscores a mission-first procurement philosophy prioritizing performance and security over socioeconomic preferences. The agency’s procurement activity is entirely concentrated under NAICS 541715, reflecting a focus on research and development in physical and engineering sciences. Arrington specializes in acquiring advanced materials R&D services, including metallurgical analysis, chemical purification processes, and engineered material characterization. Their expertise lies in procuring technical solutions that bridge laboratory-scale innovation with production-ready defense applications, particularly in high-purity metal refining and specialty chemical synthesis for defense electronics and propulsion systems.
