Andre Leslie

Andre Leslie serves as a key procurement professional within the Missile Defense Agency, supporting the development and fielding of integrated ballistic missile defense systems. He manages complex acquisition programs centered on advanced research, engineering, and system integration, with a focus on midcourse and terminal-phase interception technologies. His work directly enables MDA’s mission to enhance layered defense architectures through cutting-edge sensor modernization and guided weapon system development. Leslie typically handles high-stakes, technical contracts requiring rigorous testing, systems engineering, and rapid prototyping, often involving classified or sensitive defense capabilities. He operates within the agency’s acquisition lifecycle to ensure timely delivery of mission-critical capabilities aligned with national security priorities. Leslie maintains consistent procurement relationships with leading defense prime contractors, including Lockheed Martin Corporation and Northrop Grumman Systems Corporation, which serve as primary integrators of missile defense hardware and software systems. He also engages Jacobs Technology Inc. for systems engineering and technical assistance services. His contracting patterns reflect a preference for long-term, performance-based partnerships with industry leaders capable of delivering end-to-end solutions across multiple domains—sensor networks, command and control architectures, and kinetic interceptors. These relationships are characterized by sustained collaboration on multi-year development programs requiring deep technical alignment and rapid iteration. Leslie’s procurement portfolio shows no use of socioeconomic set-asides, with 100% of awards issued under full and open competition. This reflects the highly specialized nature of missile defense systems, where only a limited number of vendors possess the required clearance levels, technical expertise, and infrastructure to meet mission-critical performance standards. While small business participation is not formally prioritized in his portfolio, the nature of the work inherently demands Tier-1 defense contractors with proven capabilities in classified aerospace and defense environments. His primary procurement focus lies within NAICS 541715—Research and Development in the Physical, Engineering, and Life Sciences—where he acquires advanced engineering services, simulation and modeling tools, radar and infrared sensor development, and guidance system integration. His technical domain expertise spans hypersonic threat mitigation, kinetic kill vehicle design, and battle management command systems, making him a critical link between MDA’s technical requirements and industrial execution.
