Cosmetic, but it'd be nice if CVs and Fields sounded a scramble alarm/klaxon when they take fire.
If a bomb falls close enough to do dmg, or a torpedo hits the CV (without sinking it), or the auto-gunners open fire on a vessel, and the ship is not still in "scramble" state (give it a 5 minute pop?) then it would sound it's klaxon.
Fields would only be if something fell on the field and damaged it, and would have a 5-10 minute pop. Perhaps a bell ringing sound.
Very much cosmetic.
