Katherine S. Ratajczyk

Katherine S. Ratajczyk serves as a Contracting Specialist within the FA4801 49 Cons Pk under the Department of the Air Force, where she manages the acquisition of mission-critical aerospace and installation support systems essential to Air Force operational readiness. Her portfolio encompasses the procurement of advanced avionics, electronic warfare instrumentation, communications infrastructure, and maintenance services that sustain airfield and base operations. She applies full lifecycle contracting expertise to ensure compliance with FAR and DFARS requirements while aligning acquisitions with the agency’s modernization priorities in electronic systems and defense infrastructure. Ratajczyk maintains established working relationships with key contractors including UNICO GOVERNMENT SOLUTIONS, LLC, FSR CONSULTING LLC, and CERTIFIED STAINLESS SERVICE INC., among others. These partnerships reflect a balanced mix of specialized technical vendors, maintenance service providers, and instrumentation suppliers, indicating a preference for firms with proven capability in defense-grade electronics, precision manufacturing, and facility support services. Her contracting approach emphasizes reliability, technical compliance, and sustained vendor performance across long-term service and supply agreements. Her procurement patterns demonstrate a strong commitment to small business participation, with nearly half of her awards structured as Total Small Business Set-Asides under FAR 19.5. While no set-aside remains the most frequent category, her consistent use of small business contracting vehicles underscores a deliberate strategy to foster competition and expand the defense industrial base through socioeconomic programs, including those supporting service-disabled veteran-owned and woman-owned small businesses. Her primary NAICS focus areas include Other Electronic Component Manufacturing, Instrument Manufacturing for Measuring and Testing Electricity and Electrical Signals, and Machine Tool Manufacturing, reflecting deep expertise in procuring precision electronic components, test and measurement systems, and specialized fabrication equipment. She regularly engages with vendors capable of delivering ruggedized, military-spec instrumentation and maintenance solutions critical to avionics sustainment and base infrastructure resilience.
