Ethan T. Stein

Ethan Stein serves as the primary contracting professional at NAVSUP Weapon Systems Support, responsible for managing the acquisition of mission-critical aviation and weapon system components essential to U.S. Navy operational readiness. His role centers on securing specialized equipment for aircraft sustainment, avionics modernization, and power systems integration, ensuring timely delivery of high-reliability hardware across legacy and next-generation naval platforms. He handles complex, technical procurements requiring deep engineering oversight, including repairable assemblies, mission-critical electronics, and proprietary subsystems that demand strict compliance with military specifications and supply chain traceability standards. Stein maintains consistent partnerships with leading defense contractors including Northrop Grumman Systems Corporation, Thales Defense & Security Inc., and Hamilton Sundstrand Corporation, engaging them for high-performance subsystems, flight-critical electronics, and integrated avionics solutions. His procurement approach emphasizes long-term vendor collaboration, technical validation, and performance-based contracting to ensure system interoperability and lifecycle support. He frequently works with prime contractors who bring specialized manufacturing capabilities in aerospace-grade components and certified repair networks, fostering reliable supply chains for mission-essential parts. Stein’s contracting portfolio shows no reliance on socioeconomic set-asides, with 100% of awards issued under full and open competition. This reflects a strategic focus on technical capability and operational urgency over socioeconomic preferences, prioritizing proven performance and mission-critical delivery over certification-based sourcing. While small business participation is not formally incentivized, his acquisitions still engage capable small-tier suppliers through prime contractor subcontracts. His primary procurement focus lies in NAICS 336413, encompassing other aircraft parts and auxiliary equipment, with significant activity in 333998 for general-purpose machinery and 334290 for communications equipment. He specializes in procuring flight control actuators, power distribution units, radar interface modules, and mission-critical electronic assemblies, demonstrating deep expertise in naval aviation sustainment and embedded systems procurement.
