W. & O. SUPPLY, INC.

W. & O. Supply, Inc. specializes in the repair, calibration, and modernization of mission-critical marine and electronic systems for U.S. government vessels and platforms. Their core expertise lies in steering control system troubleshooting, PLC system upgrades, and printed circuit board assembly for defense and coast guard assets. The company delivers hands-on engineering support for complex electro-mechanical systems, including firmware integration, control circuit fabrication, and emergency repair of navigation and propulsion interfaces. Their technical proficiency spans industrial automation, embedded electronics manufacturing, and custom programming for vessel control architectures, enabling rapid response to operational failures in austere maritime environments. A key differentiator is their ability to bridge mechanical, electrical, and software domains—delivering end-to-end solutions for legacy systems requiring modernization without full platform replacement. The contractor maintains a consistent relationship with the Department of Homeland Security and the Department of Defense, primarily supporting U.S. Coast Guard and Navy vessels. For DHS, they execute PLC system overhauls, steering component recalibrations, and technical representation for marine automation systems. For DoD, they provide emergency electronic assembly and repair services for critical steering and control systems on maritime vessels, demonstrating a pattern of responding to urgent operational readiness needs with rapid turnaround. Their primary industry focus is shipbuilding and repair (NAICS 336611), with complementary work in printed circuit assembly (334418) and specialized technical services for industrial control systems. This positions them as a niche provider for maritime electronics sustainment, serving the unique demands of federal fleet maintenance where reliability and regulatory compliance are paramount. W. & O. Supply, Inc. is a small business headquartered in Saint Rose, Louisiana, operating as an 8H entity. While no formal government certifications are listed, their consistent performance on high-stakes maritime systems underscores their credibility in the defense and homeland security supply chain.
