I don't know what kind of material the coating is but for sure that roughness aerodynamically prevents laminar motion and allows turbulent motion, this makes an unguided bomb more stable, it is the same principle as the surface of golf balls

The material extends the amount of time a bomb in the middle of a fire will take before exploding. It's storage fire safety.

But why are some smooth and some not?

At Cv`s they are be coated, to have a bigger cook of time in case of fire, on Land they are storage in Bunkers away from any People, on a ship its difficult to storage AMMO

Honestly, not sure... but I'm guessing the earlier talk about turbulent instead of laminar is likely the key to dumb bomb accuracy. The newer JDAM types don't care about that as they are guided so maybe those are smoother for less drag/longer standoff... but that's just guessing on my part.

I don't think it has anything to do with fragmentation as that's probably formed a different way, maybe on the inside of the casting.

Different materials and fire safety requirements. Aircraft carrier = very important. Airbase with isolated earthwork storage depot = not as important.

The F/A-18C fire control computer has separate entries for certain bombs with and without the coating because it changes the ballistics (might just be weight).

Hot gasses
- lots of hot gas - stored in a form that increases their stability and density.

Since you're in Austria, they're made of Kabuhm-stoff

The rough surface on some bombs is a layer of insulation, for bombs that are carried on aircraft carriers. It increases the time needed for the bombs to cook off if there's a fire on the carrier.
