@Admiral:
AA guns are already overpowered to begin with… The radar tech makes them absurdly effective.
Putting my gripes about AA guns aside, I think all nations can benefit from this tech. Russia, Germany, Italy, and the UK for obvious reasons. As for Japan, building a few beefed up AA guns and shipping them the key islands, can really put a wrench in the Allies plans. Think of the headaches the US would have if they were unable to take islands because all of their planes have been shot down (or they are afraid of their planes being shot down). Also, radar guns on a few islands would make a pacific paratrooper campaign REALLY risky- if not impossible. They would have to put more money into land units, meaning that their navy would be less powerful, meaning Japan could put up a better fight in the Pacific… you get the idea.
The benefit of AA guns for the USA is less clear however. The first thing that comes to mind for me is shipping a few AA guns to Europe. For example, replacing the AA gun in England with an American Radar AA gun which would really help the UK player. Also, the Americans could install a radar gun in France and/ or Northwest Europe, making it much more difficult for the Germans to take those territories back.
As for adding AA capabilities to ships… Man, I would lose it if a single cruiser shot down a bunch of planes in addition to its normal defense roll!!! I think this idea wouldn’t work. It effectively gives these units two or three defense rolls. It’s WAAAY too much… And to put this into a historical perspective, battleships, while powerful, were extremely vulnerable when faced by attacks by airplanes. Just think of the Yamato!! The mightiest warship of the second world war… sunk by an American fighter squadron which lost only a dozen men in the attack!
Okay fine, only give Cruisers AA ability. Battleships are good enough as is. But I don’t think you understood what I was saying. I feel that the Radar tech is too weak, with little use for several countries, and I feel that Naval AA is something missing from Axis and Allies, so, you can kill 2 birds with 1 stone by allowing the Radar tech to upgrade a nation’s Cruisers. In defensive situations (although I wouldn’t be opposed to allowing it in offensive situations as well),
each individual Cruiser would get 1 (and only 1) preemptive roll of the dice at a “1” not a “2” fired at the attacking Air units. The attacker could still choose the casualties of course. (If there were 2 Fighters and 2 Bombers attacking 2 Cruisers, then each Cruiser would roll 1 dice at a “1” (a total of 2 dice), and then if 1 of the 2 dice “hit”, then the attacker would probably choose a Fighter as a casualty leaving 1 Fighter and 2 Bombers to fight in Round 1 against the 2 Cruisers. Round 1 would then proceed as normal, and in the following rounds, the Cruisers would NOT fire any AA shots. If you had a situation where the defender had more Cruisers in total than the number of attacking Air units, then the total number of AA shots would be limited to the same number of attacking Air units. (Example: A fleet containing a total of 4 Air units attacks another fleet containing a total of 6 Cruisers. The defender whould only roll 4 dice at “1’s”, NOT 6 dice at “1’s”. I feel that this would help to make the Radar tech more valuable for the nations for which the current Radar tech doesn’t really help. (Radar as is helps Germany and Russia some, but doesn’t help Japan and the US. UK and Italy are kind of in the middle. Radar upgrading Cruisers would help Japan and US the most, UK and Italy second, and Germany and Russia very little, so I think that this would be a balanced approach to the Radar tech.
