The flat panels on old stealth planes was actually a limitation of the software used in modeling radar reflections.
Newer iterations of the software allowed for later stealth planes to have curved surfaces.
@ryouhira i mean, humanity had over 10000 years of advancements and technological development.
Senku is quite a genious if you consider how many areas of science he knows. And not only that but also the skills to instruct people from a technical stone age into modern tech.
Crhome do have something really special: ingenuity. He is not bound by all those years of research, so ideas that would never cross their minds because they simply sound dumb come to him freely
@jasty Ships still use the flat surface kind of thing though. I expect the curved shapes probably don't contribute any speed or maneuverability advantages so they just go with the easier design to construct.
@Cheeseless
Ship's hull have to be aerodynamic to decrease the water effect on the speed and/or decrease water turbulence (which also impact speed).
As ship don't really have to be aerodynamic in the above water part (they aren't fast enough to have to take that into account), cheaper option is preferred, which coincide with flatness.
