David Purvis

David Purvis serves as a key procurement lead within the Naval Supply Systems Command Weapon Systems Support Mechanism (NAVSUP WSS Mech, N00104), where he orchestrates the acquisition of mission-critical mechanical, electrical, and electronic components essential to sustaining U.S. Navy weapon systems. His responsibilities center on securing high-reliability subsystems—including pumping equipment, valve assemblies, precision control devices, and circuit board assemblies—that ensure the operational readiness of naval platforms. He manages complex contracting actions aligned with defense acquisition regulations, prioritizing technical specifications, supply chain resilience, and lifecycle support for aging and modernized systems. Purvis maintains consistent relationships with a core group of defense-industrial contractors, most notably Raytheon Company, which appears repeatedly as a prime vendor for advanced electro-mechanical systems. He also regularly engages AMD International Technologies LLC and The Entwistle Company LLC for specialized manufacturing and component integration services. These partnerships reflect a preference for established defense contractors with proven track records in delivering high-precision, military-specification hardware under stringent quality and compliance standards. His contracting activity is overwhelmingly non-set-aside, with 99% of awards issued under full and open competition, indicating a focus on technical capability over socioeconomic preferences. Small business participation is minimal, accounting for only 1% of awards, primarily under total small business set-asides, suggesting a procurement environment driven by specialized technical requirements rather than socioeconomic mandates. Purvis’s primary procurement focus lies in NAICS 333998 (Miscellaneous General Purpose Machinery), reflecting his emphasis on custom mechanical systems and integrated assemblies. He also frequently procures components under NAICS 333914 (pumping equipment), 334419 (electronic components), and 334519 (measuring and controlling devices), demonstrating deep expertise in the integration of fluid handling, electronic controls, and precision instrumentation critical to naval weapon system sustainment.
