It can fly at an altitude of 76100 feet which is not far from the altitude at which spy planes like the SR-71 were flying. With its small size, I wonder how detectable it would be flying over a hostile zone. Given that they seem to have troubles spotting consumer drones flying at a few hundreds meters spotting for artillery in Ukraine, I imagine it might be hard to spot such a UAV at 23km high. I suppose it could be a great military asset: able to stay undetected hovering above an area of interest at an order of magnitude lower altitude than common spy satellite.
