Die Watkins-Johnson Company wurde 1957 in Palo Alto, CA, gegründet. Die Watkins-Johnson Company Telecommunications Group erstellte ab 1966 in Gaithersburg Kommunikationsequipment her und beschäftigte zuletzt 450 Angestellte.
Die Geräte von Watkins-Johnson erwarben sich rasch einen guten Namen als High-Tech-Empfänger bei militärischen und Geheimdienststellen.
Wohl nach 1998 wurde Watkins-Johnson von Marconi und dann von BAE SYSTEMS North America (British Aerospace) übernommen. Der Standort Gaithersburg wurde 2002 für 146 mio US$ von Integrated Defense Technologies IDT und diese im November 2003 von DRS Technologies Inc.
