CURTISS-WRIGHT DS, INC.

DY4 INC specializes in the design, manufacturing, and lifecycle management of mission-critical electronic systems for defense applications, with deep expertise in bare printed circuit board fabrication, printed circuit assembly, and ruggedized electronic computer manufacturing. The company delivers end-to-end solutions for obsolescence management, repair of high-reliability processor cards, and production of rugged network switches and embedded systems, ensuring sustained operational readiness for legacy and modern military platforms. Their technical capabilities span PCB-level engineering, surface-mount assembly, component sourcing for obsolete hardware, and integration of ruggedized computing architectures compliant with military environmental and electromagnetic standards. DY4 INC’s focus on total lifecycle management underscores their ability to support systems from initial procurement through sustainment, repair, and technology refresh. The contractor maintains a consistent and primary relationship with the Department of Defense, delivering hardware and engineering services across multiple command structures, including aerospace, ground systems, and naval domains. Work includes direct support to fielded platforms requiring hardware sustainment, replacement of end-of-life components, and rapid prototyping of mission-critical electronics under tight operational timelines. Industry focus centers on NAICS 334412 (bare PCB manufacturing), 334418 (electronic assembly), and 334111 (electronic computer manufacturing), positioning DY4 INC as a specialized supplier in defense electronics production rather than general IT services. Their vertical specialization lies in hardware-centric, low-volume, high-reliability systems where supply chain resilience and reverse engineering of obsolete components are mission-critical. As a small business structured as a 2L entity based in Ashburn, VA, DY4 INC operates with agility tailored to DoD procurement cycles. While no formal government certifications are listed, their consistent award history reflects proven compliance with defense manufacturing and quality standards. The company’s geographic location in a major defense and IT corridor enhances its access to federal supply chains and technical talent.
