1st Lt Dennis Sieber

1st Lt Dennis Sieber serves as Program Manager for the FA8823 Sustainment MCPNT SSC/PKL under the Department of the Air Force, where he oversees the acquisition and sustainment of critical aerospace and space-based systems essential to national defense. His role centers on managing end-to-end procurement cycles for guided missile systems, satellite communications platforms, and global positioning infrastructure, ensuring operational readiness through timely, compliant, and technically rigorous contract actions. As a key liaison between technical requirements and contractor execution, he specializes in research and development contracts that support the modernization of space and missile sustainment capabilities, bridging engineering innovation with acquisition policy to maintain strategic advantage. While specific contractor names are not currently available in the procurement record, Lt. Sieber’s portfolio consistently engages defense contractors with deep expertise in aerospace systems engineering, signal processing, and space domain awareness. He fosters long-term partnerships with firms capable of delivering high-integrity, mission-critical hardware and software solutions under strict security and compliance frameworks, often requiring ITAR-controlled supply chains and rigorous test and evaluation protocols. Lt. Sieber’s contracting activity reflects a 100% preference for non-set-aside procurements, indicating a focus on full and open competition driven by technical necessity rather than socioeconomic targeting. This approach underscores the mission-critical nature of his programs, where specialized capabilities and rapid delivery timelines take precedence over socioeconomic preferences, though small business participation is not excluded when technical requirements permit. His primary procurement focus is squarely on NAICS 541712—Research and Development in the Physical, Engineering, and Life Sciences—reflecting his specialization in advanced systems engineering, prototype development, and technology insertion for space and missile sustainment. He procures cutting-edge solutions in guidance systems, secure satellite comms, navigation integrity, and embedded software for hostile-environment operation, making him a pivotal player in the Air Force’s effort to maintain technological superiority in contested domains.
