OECO, LLC

OECO, LLC specializes in the precision manufacturing of passive electronic components for defense and aerospace systems, with deep expertise in hydrophone transformers, inductors, and related signal conditioning hardware. The company designs and produces mission-critical electromagnetic components that enable underwater acoustic sensing and aircraft power system reliability, adhering to stringent military and government specifications. Their technical proficiency includes transformer winding, core material selection, impedance matching, and environmental hardening for harsh operational conditions, particularly in naval and aviation platforms. OECO’s ability to deliver low-volume, high-reliability components under tight tolerances distinguishes them as a trusted supplier for specialized sensor and power subsystems. The contractor maintains a consistent partnership with the Department of Defense, primarily supplying electro-acoustic transducers for submarine and surface vessel sonar systems, and with the Department of Homeland Security, where they support maintenance and repair of generator controls and AC units on MH-65 Dolphin helicopters. Their work for DHS reflects a niche capability in sustaining legacy aviation power systems through component-level repair and retrofit, ensuring operational continuity without full system replacement. OECO’s primary industry focus is in the manufacturing of capacitors, resistors, coils, and transformers (NAICS 334416), with secondary engagement in air transportation support services (NAICS 488190). This dual focus positions them at the intersection of electronic component fabrication and defense aviation sustainment, serving as a specialized supplier to programs requiring custom electromagnetic solutions and aircraft system maintenance. OECO, LLC is a small business entity headquartered in Portland, Oregon, with no federal certifications on record. Their geographic presence is centered in the Pacific Northwest, and they operate as a responsive, agile supplier to government programs demanding high-integrity electronic components and targeted maintenance services for critical defense and homeland security platforms.
