I want to know the answer to the following question:
What was Raytheon previously called?
All the background I'm provided with is that "Raytheon Missile Systems (formerly Hughes Aircraft Co.), Texas Instruments, IBM, Intuit Inc., Universal Avionics, Honeywell Aerospace, Sunquest Information Systems, Sanofi-Aventis, Ventana Medical Systems, Inc., and Bombardier Aerospace all have a significant presence in Tucson.". Is that enough to answer the question?
