They said this before Vietnam and it was wrong. Ironically if truly stealth fighters with low radar and ir profiles were to engage each other in the air they would probably end up using guns primarily again as radar/ir guided missiles wouldn’t be reliable in this event.

Makes sense, it beats paying licensing for every screened device.

No he’s right. The solution for an optimal surface area to volume ratio is a sphere. The farther you deviate from a sphere the less optimal you become. The actual math for this is finding deltaSurfaceArea in respects to cylinder radius for a given volume and then finding the maxima, which is a Uni physics 1 problem I really don’t feel like doing. Long story short, optimal is when height = diameter, or as close to a sphere as a cylinder can be.
