Here is a quick tutorial on how to drop bombs which applies to all US CVs.
It guarantees bomb hits on broadsiding DDs with close to every drop.
This screenshot shows how to not aim the drop. You dont want the bombs to land on the crosshair overlapping the DD AFTER the drop.
This screenshot is a suboptimal drop you should go for if the next one is not availible. The DD needs to end up in the lower part of the reticle closer to the X as the Bombs hit the water.
This is the optimal place you want the bombs to land when they hit the water on the DD. Nearly always guaranteed one Bomb to hit and often even more than 2.
Here is a YT video showing the drops on a very small and slim ship (Umikaze) and their consistancy.
1drop:
RNG said no and Umikazes small size played a role.
2drop:
Perfect hit with 2 bombs. Perfect prediciton of the players drift.
3drop:
The crosshair overlapped the DD when bombs hit the water. This will almost never hit. 95% of the time it will be a miss. Avoid that to happen.
4drop:
Perfect drop with the guaranteed hit, only one bomb however and that with one less plane!
