We build electro-mechanical systems, wire harnesses, cable assemblies, and electronic equipment for various aircraft and other military systems.While satisfying the stringent requirements of the military has been one of the goals that Miller Stuart consistently achieves, the company also specializes in providing cost effective electronic systems for the telecommunications, computer and commuter rail industries.

From parts manufacturing to total design and delivery, MSI delivers solid solutions. Our collaborative design initiatives have brought success to companies like Fairchild-Republic on the original design of the A-10, the F-105, and SF-340; with Boeing on the A-10 wing re-design, and with Raytheon on the Sea Sparrow Missile System. Our years of experience will provide you with the confidence that the product delivered is exactly what is required, from the initial proposal to final delivery and acceptance.
