Submarines in a Convoy Sea Zone

You take away 2 ipcs from Italy and 2 from Germany.

What about fighters on an Aircraft Carrier?

They are technically part of your navy.

Do they count as -1?

Aircraft certainly could shoot convoys into the bottom of the sea…

Aircraft do no raid convoys.

Planes on carriers are just assumed to be part of the carriers’ raiding capability, so they aren’t counted separately.

another question(s):

let´s assume there two german subs in sz 109 and a german one in sz 119. how many ipcs germany could take uk away? how many scottland? (since sz 109 and 119 are neighbouring scottland it can be up to 4 ipcs, right? or is there a limit set?)

or is the convoy of sz 109 only connected to uk and the one of sz 119 to scottland?

rock`n roll

6 ipcs are taken from the UK

Scotland damage is limited to 2, the ipc value of Scotland. UK damage is thus 4

The convoy damage in sea zone 119 is limited to 2 IPCs, as it borders only Scotland.  However, since sea zone 109 borders both United Kingdom and Scotland, the convoy damage there is limited to 8 IPCs.  As Calvinhobbesliker pointed out, neither of these limits is exceeded, so the full 6 IPCs of damage is incurred.

but i can inflict up to 10 ipcs of damage in these two seazones, right?

Yes, up to 2 in 119 and up to 8 in 109.
