NAG LLC, widely recognized in the maritime industry under the trade name NAG Marine, is a United States-based systems integration and technology firm headquartered in Norfolk, Virginia. Established in 1999, the company functions as a specialized provider of ruggedized electronic equipment and automation solutions for the marine, offshore, and defense sectors. Its operational footprint extends across major naval hubs, allowing it to serve a diverse client base that includes the United States Navy, the U.S. Coast Guard, the Military Sealift Command, and various commercial fleet operators.
The company’s core identity is defined by its role as a bridge between technology manufacturers and the rigorous demands of the maritime environment. NAG LLC focuses on the engineering and adaptation of commercial off-the-shelf (COTS) technology, converting standard hardware into military-specification (Mil-Spec) systems capable of withstanding the shock, vibration, and temperature extremes inherent to ocean-going vessels. This ruggedization process ensures that critical control and monitoring equipment remains functional during adverse sea conditions and combat scenarios.
Operations at NAG LLC encompass the design, supply, and lifecycle support of shipboard systems. The company is particularly active in the fields of fluid management and digital automation. Its engineers develop and integrate solutions for monitoring tank levels, controlling valves, and managing liquid cargo, which are essential for vessel stability and environmental compliance. Furthermore, the firm supplies the computing infrastructure that underpins modern ship operations, including ruggedized servers, displays, and human-machine interfaces that allow crews to visualize and control complex machinery.
Beyond hardware supply, NAG LLC provides extensive technical services that span the entire lifespan of a vessel. The organization deploys field technicians to perform installation oversight, system commissioning, calibration, and repair directly aboard ships. It also collaborates with naval planning yards and engineering agents, supplying the technical drawings and data packages necessary for fleet modernization projects. By combining distribution partnerships with in-house engineering and field service, NAG LLC ensures the operational readiness and reliability of essential shipboard systems across the federal and commercial fleets it supports.
