The YF-23 was built by Northrop as a technology demonstrator for the US Air Force. It was a contender with the F-22, being both stealthier and faster. The F-22 was chosen because of it's agility. Two prototypes were built, the black widow and the grey ghost. As a bit of an experiment I've uploaded both versions. Enjoy!
