Kristy Tierney

Kristy Tierney serves as a key procurement professional within the W4MM USA Joint Munitions Command, supporting the Department of Defense’s mission to ensure operational readiness through the lifecycle management of conventional ammunition and explosives. She manages complex acquisitions spanning the production, storage, and demilitarization of munitions systems, with a focus on sustaining combat-effective supplies for land, air, and naval forces. Her work directly enables modernization initiatives and supply chain resilience, overseeing contracts governed by stringent safety, quality, and regulatory standards under FAR and DFARS frameworks. Tierney collaborates with a network of specialized defense manufacturers and chemical processing firms, primarily those with expertise in high-explosive formulation, precision munitions assembly, and hazardous material handling. While specific contractor names are not publicly disclosed, her procurement patterns reflect long-term partnerships with vendors holding appropriate ITAR, DD2345, and explosives handling certifications. She prioritizes vendors with proven track records in defense-grade manufacturing and secure logistics, fostering relationships grounded in compliance, reliability, and technical proficiency. Her contracting approach reflects a strong commitment to small business participation, with 20% of her portfolio allocated to Total Small Business Set-Asides under FAR 19.5. Though the majority of acquisitions remain open to all competitors, she consistently structures solicitations to encourage participation from small businesses with relevant NAICS expertise, particularly those certified in manufacturing and chemical processing sectors. Tierney’s procurement focus centers on NAICS 325920 (Explosives Manufacturing) and 332993 (Ammunition Manufacturing), with secondary emphasis on 325998 (Miscellaneous Chemical Products). She routinely procures high-energy propellants, demilitarization equipment, and specialized chemical formulations used in artillery, mortar, and guided munitions systems, demonstrating deep technical familiarity with defense chemistry, ballistic performance standards, and DoD safety protocols.
