I'm going to attempt to answer your question. First, it's unlikely that this is a real project. War companies produce lots of random ideas for presentations hoping that one of them will catch on and get an initial program funded. A few years ago there were animations of a V22 mashed up with a C130 to get a tandem winged VTOL cargo plane. The warporn gets buyers in the mood, but what they actually buy are things like the F35 program and "palletized strike missions", which is a mid-air launch system for cruise missiles. Every cargo plane with an in-air openable ramp becomes a cruise-missile launching bomber. Second, some prototype projects provide cover for other, more secret projects. If everyone knows that a lot of engineers are being hired for the SR-72 project, the fact that 25% of them are actually working on something else in the same facility is easy to disguise. Test flights of one hypersonic vehicle look pretty much the same as test flights of a different hypersonic vehicle. Third, war companies provide a lot of skilled through professional level employment in the areas where they operate, and politicians find it acceptable to run employment programs that way.
