Leonard Sims

Leonard Sims serves as a Contract Specialist within the W6QK Acc-rsa under the Department of the Army, where he plays a pivotal role in executing complex acquisitions for mission-critical aerospace and missile defense systems. He manages the full lifecycle of contract actions—from solicitation and evaluation to award and administration—for programs supporting the UH-60 Black Hawk, AH-64 Apache, and advanced guided missile platforms. His work directly enables the modernization of Army aviation and air defense capabilities, ensuring timely delivery of high-integrity aerospace systems that meet stringent military performance and reliability standards. Sims specializes in sole-source and competitive procurements governed by FAR and DFARS, with a focus on technical requirements tied to avionics, propulsion, and sensor integration. His primary contractor relationships are centered on Lockheed Martin Corporation and Alaska Aerospace Corp., both of which are key industrial partners in the development and sustainment of guided missile systems and launch infrastructure. Sims engages with these prime contractors through structured acquisition strategies that emphasize performance-based contracting, technical risk mitigation, and systems integration oversight. His approach fosters long-term, performance-driven partnerships grounded in technical transparency and compliance with defense acquisition protocols. Sims’ procurement portfolio reflects a consistent preference for non-set-aside acquisitions, with 100% of his awards issued under full and open competition. This pattern underscores a mission-critical focus on technical capability, schedule certainty, and industrial base readiness over socioeconomic set-asides, aligning with the high-stakes nature of the programs he supports. His core expertise lies in NAICS 336414—Guided Missile and Space Vehicle Manufacturing—where he procures advanced munitions, guidance systems, flight control hardware, and associated test and support equipment. He possesses deep familiarity with defense aerospace engineering standards, including MIL-STD and RTCA DO-178, and routinely evaluates technical proposals for system integration, electromagnetic compatibility, and survivability in contested environments.
