Stephen J. Girnius

Stephen James Girnius serves as a Contract Specialist at NAVSUP Weapon Systems Support, where he plays a pivotal role in securing mission-critical components for U.S. Navy aviation and weapon systems. His procurement activities center on the sustainment and modernization of aircraft subsystems, avionics, power generation units, and precision electrical instrumentation. He manages full lifecycle acquisitions under FAR and DFARS guidelines, ensuring timely delivery of high-reliability parts that support operational readiness across legacy and next-generation naval platforms. His work directly enables the agency’s mission to maintain combat-effective air and weapon systems through resilient, responsive supply chains. Girnius cultivates partnerships with a broad base of Tier 1 and Tier 2 manufacturers specializing in aerospace-grade components and defense-qualified electronics. He works closely with firms possessing AS9100 and ISO 9001 certifications, often engaging with suppliers who provide engineering support, reverse engineering, and obsolescence management for aging platforms. His contracting approach emphasizes technical compliance, supply chain traceability, and performance-based service agreements, fostering long-term vendor relationships grounded in quality assurance and mission alignment. His contracting patterns reflect a strong preference for open competition, with 96.2% of awards issued without set-asides, indicating a focus on technical capability and industrial base capacity over socioeconomic preferences. While small business participation is limited at 3.9%, it is strategically directed toward Total Small Business Set-Asides under FAR 19.5, prioritizing firms with proven expertise in niche aerospace manufacturing rather than broad socioeconomic categories. Girnius specializes in NAICS 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing), consistently procuring flight control actuators, sensor housings, and mission-critical avionics enclosures. He also regularly sources motor and generator assemblies (335312), test instrumentation (334515), and specialized electronic components (334419), demonstrating deep technical fluency in electromagnetic systems, signal conditioning hardware, and ruggedized electronic subsystems essential to naval aviation sustainment.
