Boeing’s F/A-XX entry.

It’s not a flying wing, but rather a tailless delta wing. Their designs do not use ailorons and flaps to maintain stability like Northrop Grumman’s. Instead, there are vertical stabilisers underneath the wing behind the engines.

There are also feathers on the engines to provide thrust vectoring without actually moving the engine. This is the same design that NASA and the Mitsubishi X-2 use to achieve supermaneuverability. Here’s a link to a cool image of the X-2’s feathers.

Boeing’s first design incorporated large canards. They were supsequently mocked by most people in the defense industry for placing canards on a stealth fighter, and on a tailless plane. They removed the tail to lower the plane’s radar cross signature, then put canards on the front, movable control surfaces that are impossible to make stealthy. I built a replica of their second mockup, a design without canards.

Ultimately, I don’t think that Boeing has a shot at the F/A-XX or the F-X contracts. Their design is basically a tailless 4th generation fighter.

However, it flies incredibly well in KSP (using FAR). It’s supermaneuverable, very stable, and has an internal weapons bay. The BDArmory AI can actually fly this tailless plane fairly well, so it has a good fun factor.
