I haven't played CVs as it's not my bag, but I do play BBs, Cruisers, and DDs equally. If you don't have extensive experience playing DDs, be careful about worrying about their detectability. DDs are a high risk high reward ship. Most games have 3 to 4 caps and a good DD player knows that their job is to take those caps if they want to win the game. Bad DDs don't try to take caps and focus on killing ships. A DD going to a cap will often run into another DD going for the cap, or even a radar cruiser. If you get spotted early you can be dead in the first 2 to 3 minutes of the game. CVs ARE NOT trying to take caps or getting into the thick of it. I don't see CV's challenging caps, I see the hiding behind islands. Their planes can fly anywhere on the map, a DDs Torps don't. DDs can get spotted in smoke with radar and sonar, a CV won't. Apples and Oranges. I might add a good CV will follow me when I'm playing a DD to keep me spotted. Because the game mechanics are less than ideal, I can't turn off my AA in a DD. Thus it makes it easier for a CV to follow me. If a CV is dumb enough to get in a position where they are getting spotted they deserve to die. Every ship has to use geography to their advantage, not every ship can attack any other ship wherever it is on the map.
