Maria Fonseca

Maria Fonseca serves as a key procurement professional within the W6QM Micc-Yuma Proving Ground, a critical U.S. Army facility responsible for advanced test and evaluation of defense systems. She manages complex acquisitions for specialized engineering and technical services that sustain mission-critical instrumentation, aerospace testing, and battlefield communication systems. Her portfolio centers on ensuring operational readiness through precision measurement devices, aviation support infrastructure, and high-reliability maintenance contracts. Fonseca plays a pivotal role in aligning procurement strategy with the agency’s mission to validate and enhance the performance of next-generation military technologies under rigorous environmental and operational conditions. Her primary contractor relationship is with TRAX INTERNATIONAL CORPORATION, a trusted partner delivering integrated technical services for test range operations and instrumentation support. Fonseca consistently engages TRAX for long-term, performance-based contracts requiring deep domain expertise in aerospace testing and field-deployable measurement systems. She also collaborates with a select pool of specialized vendors capable of meeting stringent military specifications, favoring partners with proven experience in defense-grade equipment integration and rapid field support. Fonseca exhibits a strong commitment to small business participation, with nearly half of her awards structured as Service-Disabled Veteran-Owned Small Business (SDVOSB) set-asides. While the majority of acquisitions remain open to all competitors, her deliberate use of SDVOSB set-asides reflects a strategic emphasis on leveraging veteran-owned enterprises with niche technical capabilities. This pattern underscores her alignment with DoD socioeconomic goals while maintaining rigorous performance standards. Her procurement focus is concentrated in NAICS 334519 (Other Measuring and Controlling Device Manufacturing) and 488190 (Other Support Activities for Air Transportation), reflecting her expertise in acquiring high-accuracy test instrumentation and aviation-specific range support services. She routinely procures calibration systems, telemetry equipment, radar calibration tools, and airfield maintenance services essential to proving ground operations, demonstrating deep technical fluency in defense testing ecosystems.
