Doesn’t the release of a concept sketch mean the prototype is working well?
dunno...nice looking concept drawing, though. Penetrating ISR.....hmmm. Does that mean it goes so fast nothing can catch it? Flies so high?
If I were going to develop a counter to one of these, I think I’d investigate some sort of atmospheric seeding combustion killer that could be dispersed by missile over a large area in front of it.... that is, if you knew where it was going
If the sr 72 really does cruise at mach 6, this plane probably can be used as a bomber. Who needs stealth when you are at mach 6. I don’t even think there are any missles except for ICBMs that can catch a mach 6 plane.
It would also make an interesting commercial plane. You can go from NY to Beijing in about 3 hours.
