The "sixth generation" term is just a pop-sci (pop-engineering?) and marketing term thrown when referring to such project on the media, it is not a formal goal

The "sixth generation" term is just a pop-sci (pop-engineering?) and marketing term thrown when referring to such project on the media, it is not a formal goal of the project. The goals of the project seem to be quite well defined, they selected a very specific set of advancements in aviation (composite airframe, electronic actuators, fly-by-fiber, etc), and warfare (electronic warfare, networking, microwave attack, etc). The article gives me the impression that it is a well managed pragmatic project based on some cutting edge concepts without going into "pie in the sky" territory.
