Raytheon Intelligence, Information, and Services Headquarters, Virginia

This division of Raytheon, one of the largest and most diversified defense contractors in the country, is focused on intelligence, surveillance, reconnaissance and cyber security. The division employs around 17,000 people, all over the world, and does work primarily for the Department of Homeland Security. Much of this division’s assets, can be traced back to Raytheon’s purchase of the Texas-based company E-Systems in 1995.
