Mark Hyun Choi

Hyun S. Choi serves as a Contracting Officer within the FA8823 Sustainment MCPNT SSC/PKL, a critical unit of the Department of the Air Force responsible for ensuring the operational readiness of guided missile systems, space vehicle platforms, and associated command, control, and communications infrastructure. In this role, Choi manages the full lifecycle of complex acquisition programs, from requirement validation and solicitation development to contract award and performance oversight. Their portfolio primarily encompasses high-technology defense systems requiring rigorous engineering validation, including satellite communications, global positioning system sustainment, and advanced navigation hardware. Choi plays a pivotal role in aligning procurement strategy with national defense priorities, ensuring timely delivery of mission-critical aerospace capabilities through compliant, risk-managed contracting practices. Choi maintains strategic relationships with a select group of prime contractors specializing in guided missile and space vehicle manufacturing, as well as defense-focused R&D firms. These partnerships are characterized by long-term collaboration on sustainment and modernization initiatives, often involving technical data rights negotiations, performance-based contracting, and systems integration efforts. While no single contractor dominates the portfolio, the contracting officer consistently engages with industry leaders possessing deep domain expertise in space systems engineering and missile lifecycle support. Choi’s procurement approach reflects a strong preference for full and open competition, with 100% of acquisitions conducted without set-asides. This reflects the technical complexity and national security sensitivity of the programs under management, where specialized capabilities and supply chain resilience take precedence over socioeconomic preferences. While small business participation is not formally prioritized through set-asides, subcontracting opportunities are actively encouraged in compliance with FAR requirements. The agency’s primary procurement focus lies in NAICS 336414 (Guided Missile and Space Vehicle Manufacturing) and NAICS 541712 (Research and Development in Physical and Engineering Sciences). Choi’s expertise centers on procuring advanced propulsion systems, space-based sensor payloads, secure communications modules, and mission-critical software for defense aerospace platforms, requiring deep familiarity with DoD acquisition regulations, technical specifications, and systems engineering standards.
