Recently Lockheed Martin put out a post on social media [1] where they showed a silhouette of a yet-to-be-revealed aircraft. Most people seem to believe it will be the reveal of their entry to the NGAD program [2] (Next Generation Air Dominance).

While not much is publically known one interesting tidbit is how much it looks like the silhouette of the Testor Corp [3] F-19 [4] model that was released back in the mid 80s. Testor said at the time that the model was based on intelligence (aka leaks) of what would eventually become the F-117.

Aviation forums in the past have said F-19 model is what they WANTED the F-117 and it does look quite a bit like the Have Blue [5] test craft they built, however, the legend is that they couldn't get the math to work for radar deflection properly at that time due to lack of computational power and ended up with the geometrically simpler F117 design we got.
