Marc Rabinowitz

Marc K. Rabinowitz serves as a Contract Specialist responsible for managing the full lifecycle of complex procurement actions, from solicitation through contract award and administration. He plays a critical role in ensuring compliance with federal acquisition regulations while advancing mission-critical capabilities for national defense and aerospace systems. His portfolio primarily encompasses high-technology acquisitions involving aircraft components, propulsion systems, and related aerospace hardware, requiring deep technical understanding and precise application of FAR and DFARS provisions. Rabinowitz routinely handles competitive sealed bidding and negotiated procurements for specialized engineering and manufacturing services, ensuring timely delivery of mission-essential equipment. While specific contractor names are not disclosed, Rabinowitz maintains consistent engagement with a broad base of Tier 1 and Tier 2 aerospace manufacturers, including firms with expertise in turbine systems, avionics integration, and guided missile subsystems. His contracting patterns reflect a preference for established industrial base partners with proven capabilities in precision manufacturing and defense-grade quality control. He fosters collaborative relationships with vendors who demonstrate technical maturity, supply chain resilience, and adherence to defense industrial base standards. Rabinowitz’s procurement strategy is overwhelmingly non-set-aside, with approximately 90% of actions conducted under full and open competition. However, he actively supports small business participation through targeted Total Small Business Set-Asides under FAR 19.5, accounting for roughly 8% of his awards, and occasionally utilizes HUBZone set-asides to promote economic development in designated areas. His approach balances competitive efficiency with statutory obligations to foster small business involvement without compromising mission readiness. His primary procurement focus lies in NAICS 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing) and 336412 (Aircraft Engine and Engine Parts Manufacturing), reflecting deep specialization in propulsion systems, flight control components, and auxiliary aerospace equipment. He also regularly procures turbine generator units and guided missile subsystems, demonstrating expertise in high-reliability mechanical and electro-mechanical systems critical to national security platforms.
