Aircraft Carrier clarification

@yazoinkergrapft Yes, the United States is allowed to declare war. If it does, the sea zone immediately becomes hostile, as there are enemy surface warships in it. However, since the United States is not declaring war until the Collect Income phase, during the Combat Move, Conduct Combat, and Noncombat Move phases the sea zone is still friendly, so the United States can still occupy it freely. On Japan’s next turn, its units in the sea zone will be starting the turn in an enemy-occupied sea zone, so the normal rules for that situation apply (those units must either move away in combat movement or attack).

@andrewaagamer Thanks!

Yes; you are right.

Awesome thank you all for the clarification!

@elevenjerk:

Cool.  Makes sense but I think (not that it means much) that planes on a carrier don’t defend in the air unless there is something to defend against.  I’m new here but I’ve been reading for well over a year and I appreciate all the info given!  Thanks!

If it helps justify it, imagine that they’re flying CAP, and were already in the air when the subs struck.  The only time aircraft aren’t considered “in the air” is when attacking with a carrier that has a friendly plane.  In all other circumstances, the airplanes are independent of the carrier (and already in the air).  Not just when attacked, but even before they were attacked.  Hence, Combat Air Patrol.

spendo is right.

SE Mexico is in a different NO, so you don’t need it in the first NO.

@marechallannes:

Q1: A battleship enters a seazone with a hostile submarine. The sub submerges.

Following the rules, the sub emerges after the combat (that doesn’t take place)

Who controlls the seazone after the battleship owners turn?

Is the sub able to raid the convoy zone in that seazone, or is it impossible, cause the battleship owner “won” the battle and controls the sea zone?

Q2: Does the sub emerges before the collect income phase of the battleship owner and is it able to raid the sea-zone of the battleship-owner?

Q3: A submarine enters a seazone with a hostile submarine. Both sub submerges before any round of combat.

Are both submarines are able to make convoy raids? (For example a UK-sub and a Jap-sub in SZ 37)

1:  No power can “control” a seazone.  That’s why you don’t mark it.  The sub is able to raid, because it remains in the seazone during the collect income phase.  Powers occupy a seazone, and a seazone can be hostile, but it’s never really “controlled”.  A power can still place units in a seazone adjacent to its factory, regardless of how many enemy units might remain in that seazone (that may even be disrupting a convoy).
2:  Yes.
3: Yes,  assuming each is present during their respective enemy’s collect income phase (when the disruption occurs).

“Submerging” is simply a term for the option to retreat but remain in the same seazone.  It serves no other function, and it does not have any impact on any other phases of a turn.  After combat, all subs are effectively no longer submerged.
