Miriam P. Callahan

Miriam P. Callahan serves as a Contract Specialist within the Headquarters Contract Operations (CG-912) unit of the U.S. Coast Guard, part of the Department of Homeland Security. In this role, she manages the acquisition of critical maritime, aerospace, and technical services essential to national security and operational readiness. Her portfolio focuses on supporting the modernization of coastal and riverine patrol fleets, enhancing maritime domain awareness systems, and sustaining specialized vessel capabilities through new construction and lifecycle support contracts. She applies full lifecycle contracting expertise—from market research and solicitation development to award and administration—to ensure compliance with federal acquisition regulations and mission-aligned outcomes. Callahan maintains consistent working relationships with key shipbuilding and defense contractors, including Bollinger Shipyards Lockport, L.L.C., Davie Defense Inc., Rauma Marine Constructions Oy, and Rozema’s Boat Works, Inc. These partnerships center on complex, mission-critical vessel construction, repair, and systems integration projects. Her contracting approach emphasizes long-term vendor collaboration, technical validation, and performance-based contract structures to ensure delivery of high-integrity maritime platforms and support services. While the majority of her acquisitions are conducted without set-asides, she consistently allocates approximately 20% of her portfolio to Total Small Business Set-Asides under FAR 19.5, reflecting a deliberate commitment to fostering small business participation in defense-related procurement. She actively seeks qualified small businesses capable of delivering specialized maritime engineering and technical services, aligning with broader DHS and Coast Guard socioeconomic goals. Her primary NAICS focus areas include professional and management development training, electronic computer manufacturing, and other engine equipment manufacturing—reflecting her procurement of advanced training systems, sensor and communications hardware, and propulsion technologies. Her technical expertise spans maritime systems integration, command and control infrastructure, and vessel modernization, positioning her as a key enabler of the Coast Guard’s operational evolution.
