Lockheed Martin is a global security company focused on domestic and foreign defense and civil markets, with the U.S. Department of Defense and other federal government agencies accounting for the majority of its business. Historically, more than 80 percent of the firm’s annual revenue has come from the U.S. government, with sales to international governments and a small amount of commercial activity making up the remainder.  

The firm designs and manufactures advanced technology systems and products, and also offers management, engineering, technical, scientific, logistics and information services.  Its activities are organized around four principal areas: aeronautics, electronic systems, information systems and global services (IS&GS), and space systems.
