Lillian M. Irby

Lillian M. Irby serves as a key procurement professional within the W6QK Acc-rsa office of the Department of the Army, supporting the modernization and sustainment of critical aerial and missile defense systems. She manages complex acquisitions for advanced aerospace platforms, including avionics, propulsion systems, and guided missile technologies essential to the UH-60 Black Hawk and AH-64 Apache programs. Her role centers on ensuring operational readiness through timely, compliant contracting of mission-critical components, working closely with engineering and technical teams to align procurement strategies with Army modernization priorities. Irby handles full lifecycle contracts—from requirements definition through award and performance oversight—focusing on high-stakes, technically demanding procurements that directly impact national defense capabilities. Irby maintains consistent working relationships with industry leaders such as Lockheed Martin Corporation and Alaska Aerospace Corp., partnering with prime contractors possessing deep expertise in aerospace systems integration, missile guidance, and flight-critical hardware manufacturing. Her contracting approach emphasizes performance-based outcomes and technical fidelity, often requiring vendors to demonstrate proven experience with military-grade specifications and rigorous testing protocols. These partnerships are built on long-term reliability, with recurring contract actions reflecting trust in contractor capability and past performance. Irby’s procurement portfolio reflects no set-aside preferences, with 100% of awards issued under full and open competition. This indicates a strategic focus on technical superiority and mission readiness over socioeconomic classifications, prioritizing capability and performance above programmatic set-asides. While small business participation is not formally incentivized in her portfolio, compliance with all federal acquisition regulations remains absolute. Her primary NAICS focus areas—334519 (Other Measuring and Controlling Device Manufacturing), 336414 (Guided Missile and Space Vehicle Manufacturing), and 541330 (Engineering Services)—reveal deep specialization in sensor systems, missile guidance electronics, and mission-critical engineering support. She procures advanced avionics, flight control units, and defense-grade instrumentation, demonstrating expertise in high-reliability aerospace engineering and systems integration for combat aviation platforms.
