6. Northrop Grumman Corporation (NYSE:NOC)
Unlike the previous three entries, which mainly provided logistics support for the military, Northrop Grumman’s bread and butter is strong weaponry, such as B2-Spirit stealth bombers, high-energy laser systems, and various drones. The company, which earned $17.69 billion in defense revenues (75% of total revenues), also provides radar and surveillance systems, as well as support for the U.S. ballistic missile program.
