Stephen Pernelli

Stephen F. Pernelli serves as a key procurement professional within the Naval Supply Systems Command Weapon Systems Support Mechanism (NAVSUP WSS Mech, N00104), where he plays a central role in sustaining the operational readiness of U.S. Navy weapon systems through the acquisition of mission-critical mechanical components. His responsibilities center on managing the procurement of high-reliability industrial valves, valve assemblies, and related subsystems essential for the maintenance, repair, and modernization of naval platforms. Pernelli’s acquisitions directly support the lifecycle management of propulsion, hydraulic, and fluid control systems aboard surface ships and submarines, ensuring compliance with stringent military specifications for durability and performance under extreme operational conditions. Pernelli maintains consistent working relationships with industry leaders such as Raytheon Company, AMD International Technologies LLC, and The Entwistle Company LLC, all of which provide specialized engineering and manufacturing capabilities for defense-grade valve systems. His contracting patterns reflect a preference for established defense contractors with proven track records in military-grade mechanical subsystems, while also engaging qualified small businesses through competitive set-asides. These partnerships are characterized by long-term technical collaboration and adherence to defense supply chain security protocols. Pernelli demonstrates a strong commitment to small business participation, with nearly half of his procurements structured as Total Small Business Set-Asides under FAR 19.5. While no other socioeconomic categories are predominant, his consistent use of small business set-asides underscores a deliberate strategy to foster innovation and capacity within the defense industrial base. His procurement focus is exclusively concentrated on NAICS 332911—Industrial Valve Manufacturing—reflecting deep technical expertise in the design, testing, and certification of pressure-rated, corrosion-resistant, and actuated valves for naval applications. He specializes in acquiring components that meet MIL-SPEC and ASME B16 standards, ensuring seamless integration into complex weapon system environments.
