Marchaunda L Tiller

Marchaunda L. Tiller serves as a key procurement professional within the Naval Supply Systems Command Weapon Systems Support Mechanism (NAVSUP WSS Mech, N00104), where she plays a critical role in sustaining the operational readiness of U.S. Navy weapon systems through the acquisition of mission-critical mechanical, electrical, and electronic components. Her responsibilities center on managing the procurement of high-reliability subsystems essential for maintenance, repair, and modernization of naval platforms, with a focus on precision-engineered components including pumping systems, valve assemblies, and current-carrying wiring devices. She ensures timely delivery of technical hardware that supports the integrity and functionality of advanced naval platforms across the fleet. Tiller maintains consistent working relationships with industry leaders such as Raytheon Company and AMD International Technologies LLC, as well as specialized manufacturers like The Entwistle Company LLC. These partnerships reflect a preference for established defense contractors with proven capabilities in defense-grade manufacturing, quality assurance, and compliance with military specifications. Her contracting patterns indicate a reliance on vendors with deep technical expertise in aerospace and naval systems integration, fostering long-term supplier collaboration to meet stringent performance and reliability standards. Tiller’s procurement activity is entirely non-set-aside, with 100% of awards issued under full and open competition. This reflects a strategic focus on technical capability and mission-critical performance over socioeconomic preferences, prioritizing vendor qualifications and system compatibility over small business set-asides such as 8(a), HUBZone, or SDVOSB programs. Her primary procurement focus lies within NAICS 332919 (metal valve and pipe fitting manufacturing), 333914 (pumping equipment manufacturing), and 335931 (current-carrying wiring device manufacturing). She specializes in acquiring precision-engineered components for hydraulic, electrical, and fluid control systems used in naval weapon platforms, demonstrating deep domain expertise in defense-critical mechanical and electronic subsystems.
