The design is credited to the author Xander619 or something like that. I made a slight but more functional modification.

MAXIMUM SPEED

The previous design had limitations, specifically the inlet at the engine nozzles that protruded above the wings for air intake. I eliminated those, which allowed me to use the air intake as designed.
This allows it to reach maximum speeds of 3600m/s; in terms of Mach, it reaches an incredible Mach 10.
What do we achieve with this? We travel a total of 3800km in 20 minutes or less. It depends on your takeoff point and destination.

maneuverability and flight

The aircraft itself isn't very good at maneuvering, because it's a supersonic, or hypersonic in this case, aircraft. It can climb to about 60,000 meters but tends to fall due to the low pressure.Even so, it manages to maintain its speed no matter if it goes up or down, only if there is no oxygen.

CONSIDERATIONS

The engineering behind the power and stability of the aircraft was hard work; the center of mass was lowered, which prevents the aircraft from twisting its pitch, in addition to giving it more control of movement.
When traveling at maximum speed or while the throttle is at 100%, it is recommended that the aircraft be in its flight position beforehand. That is to say. Its angle of attack at 9 degrees pitch, the altitude above 20,000 meters, at that moment the plane will only be able to go in a straight line.
If you wish to make a course correction, you must wait until the speed drops to at least 600 m/s, as maneuvering is not possible at higher speeds.
To prevent the ship from breaking due to friction, the cruising speed must be used at 20,000 meters or more. Use slider 1 to 100% for maximum speed position or -100% for low speed maneuvering
If you plan to fly below 600 m/s, only turn on engine 1. This ensures a low speed and prevents an unexpected surge. You won't have time to correct mistakes; it will be too late.
The suspension stiffness was reduced so that it could better perform its damping function, meaning the landing gear would withstand more impact from a hard landing.Because the plane weighs more than 200 tons
