The Boeing Bird of Prey was a black project aircraft, intended to demonstrate stealth technology. It was developed by McDonnell Douglas and Boeing in the 1990s. As an internal project, this aircraft was not given an X-plane designation. The first flight was in 1996, and some forty flights were performed through the program's conclusion in 1999. The aircraft, which had given the designation "YF-118G" as a cover, was made public on 18 October 2002. The Bird of Prey was put on display at the National Museum of the USAF at Wright-Patterson AFB on 16 July 2003.
