Holding a part number or NSN? Check it against every part we have repaired.

Duotech is a trusted, requirements-driven company structured to solve the modernization, engineering, reverse engineering, repair, sustainment, and re-manufacturing problems of military and civilian agencies, as well as aerospace and commercial users of electronic and electromechanical equipment.

We save our clients millions of dollars annually by providing expert aftermarket services for their legacy electronics systems, increasing defense platform operational availability, and helping clients free up time, money, and resources to apply to other initiatives. Whether it is repair of embedded electronics, designing and building market-leading automated test equipment (ATE) solutions to resurrect and optimize a test bed, or building advanced RADAR and electronic warfare (EW) products, we are typically faster and more cost-effective than what many clients could achieve using their own organic resources.
