Was doing E4, which is mostly a sub map. Came back with my entire fleet only using 2 bars of ammo (this is likely due to the pre-boss node where they were shelling). The rest of the nodes were all ASW only. Had 4DDs 1CL 1BBV.

I think it's pretty reasonable to conclude that if your ships don't use their main guns during battle, it doesn't consume any ammo at all.
