Douglas Aircraft used Northrop's multicellular wing design in its DC-3. In 1939 he founded Northrop Aircraft, Inc., which he led until 1952. It produced the F-89 Scorpion interceptor, P-61 Black Widow night fighter, and Snark intercontinental missile. His flying wing project was ultimately the basis for the B-2 stealth bombers.
