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. Funded by the company at a price of $67 million it was a low cost program compared to many other programs of similar scale. It developed technology and materials which would later be used on Boeing's X-45 unmanned combat air vehicle. As an internal project this aircraft was not given an X-plane designation.
