Mark C McWhorter

Mark C. McWhorter serves as a key procurement professional within the Naval Supply Systems Command Weapon Systems Support Mechanism (NAVSUP WSS Mech, N00104), where he supports the operational readiness of U.S. Navy weapon systems through the acquisition of mission-critical mechanical, electrical, and electronic components. His responsibilities center on managing complex contracts for high-reliability subsystems, including pumping systems, valve assemblies, printed circuit boards, and precision bearings essential to the sustainment and modernization of naval platforms. McWhorter’s work ensures the continuous availability of technically demanding parts that maintain the combat effectiveness of advanced naval vessels and systems. He maintains consistent contracting relationships with leading defense and industrial suppliers, most notably Raytheon Company, AMD International Technologies LLC, and The Entwistle Company LLC. These partnerships reflect a preference for established Tier-1 and specialized niche manufacturers capable of meeting stringent military specifications for performance, durability, and traceability. His procurement approach emphasizes technical compliance, supply chain resilience, and long-term vendor reliability over transient cost savings. McWhorter’s contracting portfolio is overwhelmingly dominated by open, non-set-aside acquisitions, with 97.3% of awards issued without socioeconomic preferences. While small business participation is limited, the 2.8% allocated to Total Small Business Set-Asides indicates a measured, compliance-driven engagement with qualified small vendors, primarily in specialized manufacturing niches. His technical focus lies in NAICS categories including 332919 (metal valve and pipe fitting manufacturing), 334412 (bare printed circuit board manufacturing), and 334290 (communications equipment manufacturing), reflecting deep expertise in electromechanical systems, signal integrity components, and precision fluid control hardware. He routinely procures items requiring MIL-SPEC compliance, RoHS adherence, and full lot traceability, underscoring his command of defense logistics and high-reliability component sourcing.
