@marshmallowofwar thanks to both you and @AndrewAAGamer for clarifying. Thought I had a sneaky way to slow him down, but will have to give it some more thought!
Yes the sub can still cause disruption , but if a German sub is there then Russia doesn’t get the 5 pu bonus NO money because there is a warship in 125.

The rules for scrambling specifically state that you may only scramble if combat is occurs in the sea zone surrounding the island with the air base. This combat may be either a straight naval battle if defending naval units exist in the sea zone or just an amphibious attack launched from the sea zone if there are no existing defending naval units.
