In an effort to establish leadership in the defense electronics business, Raytheon purchased in quick succession Dallas-based E-Systems (1995), Chrysler Corporation's defense electronics and aircraft-modification businesses (1996) (portions of these businesses were later sold to L-3 Communications), and the defense unit of Texas Instruments - Defense Systems & Electronics Group (1997). Also in 1997, Raytheon acquired the aerospace and defense business of Hughes Aircraft Company from Hughes Electronics Corporation — a subsidiary of General Motors, which included a number of product lines previously purchased by Hughes Electronics including the former General Dynamics missile business, the defense portion of Delco Electronics (Delco Systems Operations), and Magnavox Electronic Systems.
