Stephanie A Diehl

Stephanie A. Diehl serves as a Contract Specialist within the Naval Air Systems Command (NAVAIR), where she plays a critical role in executing the lifecycle acquisition of naval aviation systems. Responsible for soliciting, negotiating, and administering complex contracts, she supports the procurement of aircraft, propulsion systems, avionics, and associated logistics infrastructure essential to maintaining U.S. Navy and Marine Corps air superiority. Her work spans the full spectrum of defense acquisition phases—from research and development through sustainment—ensuring compliance with federal acquisition regulations and mission-critical timelines for carrier-based and expeditionary aviation platforms. Diehl maintains sustained contracting relationships with leading defense prime contractors including Sikorsky Aircraft Corporation, Lockheed Martin Corporation, and General Atomics, partnering with firms that deliver advanced rotary-wing and fixed-wing platforms, unmanned aerial systems, and mission-critical avionics. Her procurement patterns reflect deep collaboration with Tier-1 aerospace integrators with proven capabilities in systems engineering, flight testing, and depot-level maintenance, ensuring seamless integration of cutting-edge technologies into the naval aviation fleet. Her contracting portfolio demonstrates a consistent preference for full and open competition, with no set-asides applied across her awarded actions. This reflects a mission-driven focus on technical capability and operational readiness over socioeconomic preferences, though she remains attentive to small business participation where it aligns with performance requirements and industrial base resilience. Diehl’s primary procurement focus lies within NAICS 336412 (Aircraft Engine and Engine Parts Manufacturing), 336411 (Aircraft Manufacturing), and 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing), underscoring her expertise in propulsion systems, airframe integration, and flight-critical components. She also regularly engages engineering services firms under NAICS 541330 to support technical analysis and systems certification, demonstrating specialized knowledge in aerospace systems engineering and defense logistics.
