The F-119 never existed.

I may be wrong, but if I remember correctly the F-119 was what the media called the stealth fighter the Lockheed Martin was developing. Ultimately, the real stealth fighter was designated the F-117. There was a lot of speculation about what the stealth fighter would look like, and some of the ideas were made into plastic model kits (which were very popular).

If you're interested in stealth aircraft, I would recommend you read Skunk Works by Ben Rich. He was the director of the Lockheed Martin Skunk Works during the design and construction of the F-117. Very good book with a lot of interesting information on the Nighthawk.
