| | + | Originally 132 were to be built, but rising costs (a near certainty in military programs) caused the program to be cut to a mere 21. Twenty are still in operation (one was lost in a 2008 crash), of which 19 are located in [[Missouri]] and the 20th at Edwards Air Force Base in [[California]] which serves as a flight test vehicle. All 21 were given the name "Spirit of" followed by a state name (except the 1st, named Spirit of America, and the 19th which was named Spirit of Kitty Hawk), "Kansas" was the one lost in the crash. |
| | Much of the design for the B-2 Spirit came from [[Jack Northrop]], the founder of what is now known as Northrup Grumman. In 1946 the United States military looked for a bomber to replace the aging, [[B-52]] bomber. They wanted a plane that was more advanced and one with better range. The military awarded Jack Northrop with a 88 million contract to build a new bomber. Northrop began working on an idea for a plane which he called the "[[Flying Wing]]". But in 1947, the Air Force mysteriously ended his contract, and the project ended.<ref>{{cite web|url=http://www.dau.mil/pubs/arq/2001arq/Baker.pdf|title=Clipped Wings: The Death of Jack Northrop's Flying Wing Bombers|author=Dr. Bud Baker|format=PDF|language=English|accessdate=2007-08-20}}</ref> The [[United States Air Force]] restarted it quest for a better bomber in 1970.
