Susan M McArdle

Susan M. McArdle serves as a key procurement lead within the Naval Supply Systems Command Weapon Systems Support Mechanism (NAVSUP WSS Mech), where she manages the acquisition of mission-critical mechanical, electrical, and electronic components essential to sustaining U.S. Navy weapon systems. Her responsibilities center on ensuring operational readiness through the timely procurement of high-reliability subsystems, including pumping systems, valve assemblies, and precision electronic components. McArdle oversees contract actions aligned with modernization and maintenance cycles for naval platforms, focusing on technical domains requiring stringent quality control and defense-grade compliance. Her work directly supports the agency’s mandate to maintain the integrity and functionality of advanced naval weapon systems across the fleet. McArdle maintains consistent, long-term relationships with prime contractors including Raytheon Company, AMD International Technologies LLC, and The Entwistle Company LLC, all of which provide specialized engineering services and mission-critical components. Her contracting patterns reflect a preference for established defense industrial base partners with proven track records in delivering high-integrity electronics and system integration solutions. These partnerships are characterized by repeat engagements, performance-based contract structures, and a focus on technical reliability over cost alone. McArdle’s procurement portfolio is entirely non-set-aside, with 100% of awards issued under full and open competition. This reflects a strategic emphasis on accessing the broadest possible pool of qualified vendors capable of meeting the rigorous technical and security requirements of naval weapon systems, rather than targeting socioeconomic categories. While small business participation is not formally incentivized in her portfolio, vendors must still meet stringent qualification standards regardless of size. Her primary procurement focus lies in NAICS 541512 (Computer Systems Design Services), which accounts for 75% of her activity, encompassing embedded systems design, firmware development, and test equipment integration. The remaining 25% falls under NAICS 334419 (Other Electronic Component Manufacturing), targeting custom circuit board assemblies and specialized electronic modules. McArdle’s expertise centers on the procurement of complex, low-volume, high-reliability components critical to naval combat systems.
