I'm not really sure what factor ( x2? x3? x4?) aircraft AD should be increased by: I just mentioned "twice" above as an alternative to doubling the number of aircraft Flights on a carrier, as increasing the AD by two would have the same effect on combat. I just know they're too low now, and need to be increased.
If folks are really concerned with aircraft "taking over", then do what WWII naval gamers have been doing for the last 30+ years to avoid the historical dominance of aircraft over ships in the period: play night actions, play without carriers, or simply specify "no aircraft" scenarios and go from there. Run campaigns that limit the number of aircaft that are available to the players. Don't nerf the rules just because you want to play surface actions.
As to torpedo reloads, this came up in discussion during our first Guadalcanal game. According to our resident IJN player/authority, VaS has at least that aspect of things pretty well covered in the ships they have statted out so far. (He's also our Seekrieg fan, so getting him to say something nice about VaS is a bit of an accomplishment. :wink: )
As VaS says, the Fubukis were the first IJN DD's to carry torpedo reloads, but used a cumbersome system to get them on deck that effectively made it impossible to reload during a battle. "One Shot" reflects this nicely for them.
The Kageros and later designs used a much-improved system that allowed torps to be reloaded much more quickly, and "Slow-Loading" reflects that nicely in game terms.
I would suggest some limit on the number of times torps can be reloaded, however.
Back at the Dawn of Time when we had to chip ship miniatures out of flint, our old Seapower rules allowed reloading torpedos but each ship's stats also included the total number of torps onboard: once you'd fired them all away, you were done.
