William J Grun

William J. Grun serves as a Contracting Officer responsible for managing complex procurement actions within the defense and aerospace sectors. He oversees the full lifecycle of acquisition programs, from solicitation and evaluation to contract award and administration, ensuring compliance with the Federal Acquisition Regulation and national security requirements. His portfolio centers on high-precision manufacturing and technical support services critical to aviation systems, reflecting a mission-driven focus on sustaining airworthiness and operational readiness. Grun routinely handles competitive and non-competitive contracts for specialized components and subsystems used in military and civil aircraft platforms. While specific contractor names are not available, Grun’s procurement patterns indicate consistent engagement with Tier 1 and Tier 2 aerospace suppliers, precision machine shops, and technical consulting firms. His working relationships emphasize performance-based contracting, rigorous source selection under FAR Part 15, and stringent technical evaluation criteria to ensure quality and compliance. He maintains a preference for established industrial base vendors with proven capabilities in certified manufacturing environments, particularly those adhering to AS9100 and ITAR standards. Grun’s contracting activity reflects a strong emphasis on open competition, with 92% of awards issued without set-aside restrictions. However, he actively supports small business participation, consistently allocating approximately 8% of his portfolio to Total Small Business Set-Asides under FAR 19.5. This demonstrates a balanced approach—prioritizing market efficiency while ensuring opportunities for qualified small businesses to contribute to critical aerospace supply chains. His primary procurement focus lies in NAICS 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing), accounting for 80% of his activity, followed by aircraft manufacturing (336411) and precision machining (332710). He procures mission-critical components such as flight control actuators, avionics housings, and propulsion subsystems, requiring deep technical expertise in aerospace engineering and supply chain resilience. His domain knowledge spans materials science, quality assurance protocols, and defense logistics, positioning him as a key steward of national aerospace capability.
