Why are bombs shaped like bombs and not spheres?

Why are bombs, the ones dropped from airplanes, shaped like an oval with fins on one end? Why aren’t they spheres so they just fall down onto the target?

Some additional info for you OP. Others have mentioned the magnus effect. We have utilized this effect in the past, before we had the ability to target individual structures with accuracy.

Skip bombs aka dam busters were cylindrical bombs utilized during ww2. They would spin up the bombs before releasing them over water, well before thier target. The magnus effect would cause enough momentum to be transferred from downwards motion to forwards motion that the bombs would not detonate on impact with the water. Instead they would skip across the water like a stone, only detonating once they struck a vertical object. (Hopefully the dam)

Spinning spheres move in curved paths from a thing called the Magnus effect. That’s what’s happening when a baseball pitcher throws a curveball.

This makes it very hard to aim a spherical bomb. It’s the same reason armies stopped using round musket balls. It won’t just follow the predictable ballistic path. If it happens to backspin, it will generate some lift, making it overshoot the target. If it happens to topspin, it will dive down sharper and undershoot the target. If it happens to side spin, it will drift to the side.

The elongated shape with the fins in the back forces it to follow a predictable ballistic path instead of the crazy curve a sphere would have.

Edit: Also it makes it predictable which part of the bomb will impact first – it will be the nose. That makes it possible to know where to build the impact trigger switch.

They are shaped like spheres. Have you even played Mario?

They are shaped to reduce drag during flight. Spheres are not very aerodynamic.

Then bombs are standard, rarely you see different designs for exterior and interior carried bombs. Most cases they make an exterior carried bomb and then used it for interior carrying too.

Then when you drop them you want the bomb to spin to retain accuracy, so you need a fin with a twist. Again sphere with fin is not practical. The more elongated the bomb is the less it aerodynamically mask the fin. Too elongated it becomes unstable during the spinning. So you see that 2 to 10 ratio in length to width. The most elongated, the 10, are made with fast jets carrying them outside in mind.
