The UHV-1 (Unmanned Hypersonic Vehicle) is a hypersonic research aircraft produced by Dank Memes 4 Life. It was built to provide a greater understanding of the characteristics of high-supersonic and hypersonic flight. After a few successful test flights, some important data was gathered about flying at extremely high speeds:

At low altitudes, less is more. Less pitch will result in greater maneuverability.
Using full elevator will act as an airbrake.
At around 27,000 ft, the aircraft can pitch with full elevator without slowing down, but using less will still make it turn better.
In a previous version, the plane would go extremely unstable and explode right past 3,800 mph, steps were taken to correct this but it has not been tested.

From the collected data, an improved version is currently under development. It is capable of going even faster than its predecessor, using the same powerplant.
