Divebombers can be better on some maps with heavy armor installation-type bosses though.

Divebomber keeps your CV from attacking heavy armor installation so that they'll focus on the other enemies. Usually you want to take out the heavy armor installation with T3 shell at night, so during day, it's really important to knock out everything else.

Example is 4-5.. I always try to put 1 divebomber on each CV for 4-5.
