Stephen B. Mangan

Stephen B. Mangan serves as a Contract Specialist within the FA4419 agency of the Department of the Air Force, where he plays a pivotal role in executing mission-critical acquisitions to sustain and modernize air base infrastructure and aerospace systems. He manages a diverse portfolio of contracts spanning aircraft maintenance components, facility utilities, and mission support equipment, ensuring operational readiness through timely and compliant procurement actions. His work directly supports the agency’s strategic priorities in aircraft sustainment, environmental system upgrades, and logistical resilience, requiring deep familiarity with FAR and DFARS compliance, source selection methodologies, and performance-based contracting. Mangan maintains a consistent working relationship with COORDINATED DEFENSE SUPPLY SYSTEMS, INC., a key vendor providing specialized aerospace parts and auxiliary equipment. His contracting patterns reflect collaboration with a mix of large prime contractors and small business subcontractors, often structured through indefinite-delivery/indefinite-quantity (IDIQ) and requirements-type contracts. He prioritizes clear performance metrics and post-award oversight to ensure delivery of mission-essential capabilities under tight operational timelines. His procurement strategy reflects a balanced commitment to socioeconomic goals, with approximately half of his actions set aside for small businesses under FAR 19.5, while the remainder remain open to full and open competition. This dual approach ensures broad market engagement while actively fostering small business participation in defense logistics and infrastructure support. Mangan’s primary NAICS focus areas include 336413 for other aircraft parts and auxiliary equipment, 811310 for commercial and industrial machinery repair, and 334118 for computer peripheral equipment manufacturing. He also routinely procures specialized services related to tile and terrazzo contracting and recreation infrastructure, reflecting the agency’s broad facility sustainment mission. His expertise spans both high-tech aerospace components and facility maintenance services, demonstrating a unique blend of technical and operational procurement acumen across diverse industrial sectors.
