Samuel Tustin

Samuel J. Tustin serves as a key procurement professional within the Naval Supply Systems Command Weapon Systems Support Mechanism (NAVSUP WSS Mech, N00104), where he facilitates 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 systems, valve assemblies, precision gears, and specialized electronic components—required for maintenance, repair, and modernization of naval platforms. Tustin’s work directly supports operational readiness by ensuring timely delivery of components that meet stringent military specifications and environmental durability standards. He maintains consistent contracting relationships with industry leaders such as Raytheon Company and AMD International Technologies LLC, alongside specialized manufacturers like The Entwistle Company LLC. These partnerships reflect a preference for established defense contractors with proven track records in producing aerospace-grade and naval-certified components. Tustin’s contracting approach emphasizes technical compliance, supply chain resilience, and vendor capability to meet complex military performance requirements, often involving custom-engineered solutions for hardened environments. While the majority of his acquisitions are conducted under full and open competition (83%), Tustin actively supports small business participation, with 17% of awards designated as Total Small Business Set-Asides under FAR 19.5. This reflects a deliberate effort to integrate capable small manufacturers into the naval supply base, particularly those with niche expertise in precision machining and electronic subsystems. His procurement focus is concentrated in NAICS sectors including industrial fan and blower manufacturing (333413), high-speed gear and drive systems (333612), and aeronautical navigation system manufacturing (334511), underscoring deep technical expertise in mechanical motion control, fluid systems, and avionics-grade electronics. Tustin’s portfolio demonstrates a specialized command over the acquisition of mission-critical components that directly enable the functionality and longevity of naval weapon systems.
