Liem M Phan

Liem Phan serves as a key procurement professional within Navsup Weapon Systems Support, supporting the Department of the Navy’s mission to sustain and modernize naval aviation and weapon systems. Responsible for managing complex acquisitions of mission-critical components, Liem specializes in sourcing specialized aircraft parts, avionics subsystems, and power generation equipment essential to fleet readiness. Their work directly enables the maintenance, repair, and upgrade of legacy and next-generation naval aircraft platforms, ensuring operational continuity through reliable supply chain execution. Liem handles competitive and sole-source contracts under FAR and DFARS guidelines, with a focus on technical specifications for high-reliability aerospace and defense-grade hardware. Liem collaborates with a diverse base of Tier 1 and Tier 2 aerospace suppliers, including manufacturers of flight-critical avionics, engine components, and auxiliary systems. While no single contractor dominates their portfolio, partnerships are typically formed with firms possessing AS9100 certification, ITAR compliance, and proven track records in defense aerospace manufacturing. Relationships are built on technical rigor, quality assurance adherence, and timely delivery performance, with an emphasis on sustaining long-term supplier capabilities for mission-essential parts. Liem’s contracting activity shows no preference for socioeconomic set-asides, with 100% of acquisitions conducted under full and open competition. This reflects a strategic prioritization of technical capability and supply chain reliability over socioeconomic criteria, aligning with Navsup WSS’s operational imperatives. While small business participation is not formally incentivized, qualified small vendors are evaluated on merit, with selection driven by compliance, performance history, and technical alignment. Liem’s procurement focus centers on NAICS 336413 for other aircraft parts and auxiliary equipment, with secondary emphasis on aircraft engine components (336412) and communications equipment (334290). Their expertise lies in procuring precision-engineered metal components, flight control actuators, power distribution units, and mission-specific electronic subsystems. This technical domain requires deep familiarity with MIL-SPEC standards, obsolescence management, and engineering change control processes critical to sustaining naval airworthiness.
