Sheena Warner

Sheena Warner serves as a key procurement specialist within the Defense Logistics Agency’s Aerospace Energy office (SPE601), responsible for securing critical energy and gas supply chains essential to DoD operational readiness. Her role centers on managing the acquisition of high-purity industrial gases—including aviator breathing oxygen, liquid oxygen, and liquid nitrogen—as well as rocket-grade propellants and associated storage and logistics infrastructure. She ensures timely, compliant, and mission-critical deliveries to aerospace and defense platforms, aligning procurement actions with national security priorities and stringent quality standards for cryogenic and hazardous materials. Her acquisitions are technical, highly regulated, and require deep domain knowledge of gas purity specifications, transportation safety protocols, and military-grade certification requirements. Warner maintains long-standing relationships with a small group of specialized industrial gas suppliers, most notably Airgas USA, LLC, Okano, K.K., and Toshan Co., Ltd. These contractors are selected for their proven capability in producing and delivering ultra-high-purity gases under strict DoD specifications, often requiring global logistics networks and certified cryogenic handling expertise. Her contracting patterns reflect a preference for established, technically qualified vendors with validated track records in aerospace and defense applications, emphasizing reliability, consistency, and compliance over competition volume. Her procurement activity shows no use of socioeconomic set-asides, with 100% of awards issued under full and open competition. This reflects the highly specialized nature of the products procured, where only a limited number of global manufacturers meet the technical and certification thresholds required for military use. Small business participation is not a primary driver in this domain due to the capital intensity and technical barriers to entry. Warner’s work is concentrated exclusively under NAICS 325120 (Industrial Gas Manufacturing), underscoring her deep expertise in the production and supply of mission-critical gases for aerospace propulsion and life support systems. Her focus is on technical specifications, gas purity levels, packaging integrity, and just-in-time delivery systems that support flight operations and ground-based defense systems.
