In Axis and Allies 1941, submarines can make a surprise attack
surprise strike: Each attacking submarine conducting a surprise strike rolls one die, scoring a hit on s roll of 2 or less. After an attacker has rolled for all attacking submarines, the defender chooses one sea unit for each hit and moves it behind the casualty strip (submarines cannot hit air units). The each defending submarine conducts surprise strike rolls, scoring a hit on a roll of 1. After the defender has rolled for all defending submarines, the attacker chooses one sea unit for each hit scored and removes it from play.
That seems straightforward enough, but what if it's the first round of combat and a loaded aircraft carrier is taken out (let's say one sub vs one carrier with one fighter on it)?
There appear to be no rules to the contrary, so it would seem that the fighter remains in play, assuming it was launched - especially as the carrier is placed on the casualty strip, not removed.
However, it makes me wonder if the fighter had time to launch. After all, this was a surprise strike, so the fighter shouldn't have taken off at least on the first round. Should it be on the casualty strip with the carrier?
