The military does not have relatively silent supersonic flight. Only a few US military aircraft models are even capable of supersonic flight, and they're plenty loud. In order to avoid complaints they normally they only fly that fast over designated exercise areas.
The Boom aircraft incorporates some quiet supersonic technology but until they actually test it they won't know whether it's actually quiet enough.
- kachapopopow 2y ago'commercial' military planes - no, prototypes - yes.
- nradov 2y agoPrototypes - no. There is the X-59 but that's civilian (operated by NASA), not military. Some of the research results from the X-59 program are being used by Boom and future military designs.
- kachapopopow 2y agoObviously as some point the military would have researched this technology, that's not even a question. We will make know more in few decades or so once that information is declassified.
- JumpCrisscross 2y ago> military does not have relatively silent supersonic flight We have one plane—soon to be retired—that can supercruise, i.e. sustain supersonic flight without afterburners, the F-22 [1]. It’s absolutely incorrect to treat this technology as anything but bleeding edge. [1] https://en.m.wikipedia.org/wiki/Supercruise https://en.m.wikipedia.org/wiki/Supercruise
- nradov 2y agoAbility to supercruise mainly only matters for fuel efficiency. It makes little difference to the shock wave volume on the ground. If a Raptor cruises overhead at Mach 1.5 you're going to notice.
