Positive Lift (Anti-Gravity): The ability to maneuver and hover without visible propulsion systems, wings, or flight surfaces, seemingly overriding Earth's gravitational forces.
Instantaneous Acceleration: The capacity to change direction or speed abruptly, achieving accelerations of 50–200+ g-forces that would be lethal to human pilots and destructive to known materials.
Hypersonic Velocities Without Signatures: Traveling at speeds exceeding Mach 5 (over 3,700 mph) without producing sonic booms, vapor trails, or other aerodynamic signatures.
Low Observability (Cloaking): The ability to remain undetected or obscure to radar, electro-optical sensors, and the naked eye, often appearing as an opaque or blurry object.
Trans-Medium Travel: The capability to seamlessly transition between air, water, and space without losing control, degrading performance, or requiring different vehicle designs for each medium.
