Escorting bombers does not achieve air superiority. For that you have to sweep. If Tojo can't get there and Oscar can, you need Oscars. LR CAP is a better technique than escort as well. If your pilots are good enough they can handle Hurricanes and Spits and P-40s and P-39s and P-38s in these roles. Make sure your pilots are exp. 80. Once the Allied player transitions to the offense you're not likely to accomplish much bombing his bases in most cases except China and Burma. Your bombers should be transitioning to Naval Search, Naval Attack and ASW. The more tasks your air crews learn the higher their experience level goes and in some cases their defensive skill which helps preserve planes and crews. Again, in the escort role it doesn't matter how good the fighter is, they could be shot down in droves, so don't do that.
Ask yourself if the bombing campaign will accomplish more than those fighter pilots' worth. Also, after the first few months do not use Bettys or Nells in bombing campaigns unless you've lost most or all of your carriers and it doesn't matter anymore. Bettys and Nells are for search and training carrier aircrews.
Betty for search only, you are joking!
I have had great results with my Betty bombers, reaching out long range to interdict shipping.
But then again you need to place them at the strategic locations.
And Oscars sweeping hahaha try that in end 1943! you will have lots of space in the hangar after the mission.
About the bombers, the bombing missions i plan have a goal, and only then i commit the units to it.
Sweeping missions need to be planned well, and executed well.
And my plans do not have any oscar in it. It is a crappy plane and a PBEM game as japan will show it.
And thats final!
Green lizard or not!
