Heather T. Duffy

Heather T. Duffy serves as a Contract Specialist within the W4MM USA Joint Munitions Command, a critical component of the Department of Defense responsible for the lifecycle management of conventional ammunition and explosives. In this role, she executes full-cycle procurement actions for complex munitions systems, technical services, and engineering support essential to sustaining combat readiness across land, air, and naval forces. Her responsibilities include developing solicitation documents, conducting market research, evaluating proposals, and administering contracts aligned with federal acquisition regulations and defense-specific requirements. She plays a pivotal role in ensuring timely acquisition of mission-critical capabilities that support modernization initiatives and supply chain resilience. Heather collaborates with a diverse range of defense contractors specializing in aerospace components, military-grade engineering services, and professional technical support. While no single vendor dominates her portfolio, she consistently engages with firms possessing relevant security clearances, manufacturing certifications, and defense supply chain experience. Her contracting approach emphasizes performance-based outcomes, risk mitigation, and compliance with Department of Defense standards, fostering long-term partnerships with qualified industry providers capable of delivering high-integrity munitions-related solutions. Her procurement activities reflect a strong preference for open competition, with 100% of her acquisitions issued without socioeconomic set-asides. This indicates a strategic focus on technical capability and mission necessity over socioeconomic criteria, prioritizing best-value outcomes through broad market engagement. While small business participation is not formally targeted in her portfolio, she remains compliant with all statutory requirements and may incorporate small businesses as subcontractors when technically justified. Heather’s primary procurement focus lies in NAICS 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing), 541330 (Engineering Services), and 541990 (All Other Professional, Scientific, and Technical Services). She routinely acquires specialized munitions components, ordnance system integration support, and technical advisory services critical to ammunition production, storage safety protocols, and demilitarization operations. Her expertise spans defense engineering, explosive safety standards, and logistics lifecycle management within the munitions domain.
