Northrop Grumman

Builds stealth bombers, missiles, and satellites

Northrop Grumman builds military aircraft, missiles, rocket motors, satellites, and electronic systems, mostly for the American military and allied governments. It designed the B-2 stealth bomber and built NASA's James Webb Space Telescope, the largest telescope ever sent to space. The company works through four businesses: aircraft, missiles and ammunition, radar and communications systems, and space hardware such as satellites and solid rocket boosters. Most revenue comes from long-term government contracts, many of them classified. Its roots go back to Northrop Aircraft, founded in 1939, and it took its name after buying Grumman in 1994 and is based in Falls Church, Virginia.
