Sarah Lewellen

Sarah Lewellen serves as a key procurement lead within the Commander (M00264) under the Department of the Navy, responsible for managing mission-critical acquisitions that sustain and modernize naval warfighting systems. She oversees contracts supporting command and control architectures, tactical computing environments, and integrated sensor and armored vehicle systems, ensuring operational readiness through advanced technology integration. Her portfolio emphasizes systems engineering, cyber-enabled decision support, and maintenance of mission-critical infrastructure, aligning directly with the agency’s focus on next-generation naval capabilities and sustained combat readiness. Lewellen maintains consistent partnerships with a core group of specialized contractors including GoldBelt Hawk L.L.C., Alex-Alternative Experts, LLC, Tnda Technologies Inc., BC Market Solutions LLC, and Biospace, Inc. These vendors provide niche expertise in equipment maintenance, technical support services, and mission-specific manufacturing, reflecting a preference for agile, responsive suppliers capable of delivering tailored solutions under demanding operational conditions. Her contracting patterns suggest a reliance on trusted, repeat performers with proven experience in defense-related environments and rapid deployment capabilities. Her procurement strategy prioritizes flexibility, with 62.5% of awards issued without set-aside designations and 37.5% awarded under Total Small Business Set-Aside provisions per FAR 19.5. This balance indicates a deliberate approach to leveraging small business innovation while maintaining access to specialized capabilities that may only be available through larger or non-traditional vendors. She actively integrates small businesses into the supply chain, particularly those with expertise in niche technical domains relevant to naval operations. Lewellen’s primary procurement focus centers on NAICS 811310, reflecting heavy investment in commercial and industrial machinery repair and maintenance for naval platforms. She also frequently procures services under NAICS 339999 for miscellaneous manufacturing and 611699 for specialized technical instruction. Her expertise lies in acquiring complex, non-standard equipment and maintenance services critical to sustaining armored vehicles, tactical computing hardware, and sensor systems, demonstrating deep familiarity with defense logistics and field-deployable technology sustainment.
