Naval transports that can carry aircraft (aircraft carriers)

So a few of us were talking on Global last night saying that naval units should be able to carry air units. At first, I stated that this was a silly idea, since aircraft don't need to be carried. first it was pointed out to me that the transports could be given a larger movement speed than the aircraft, which would make a legitimate reason to use them. Also as we later got into a discussion about a nuclear war map, somebody pointed out that there could be nukes that could be put onto submarines specifically made to carry nukes, which would be able to be able to get closer to the target without the missile being seen, and then launch them so close to the enemy that they have no time to react.
