Actually I didn't see my endorsement on any of the ideas. I'm simply throwing out other ideas from other posts to show how the greedy and selfish would suffer for their dispostion.
However since you brought it up, If there were to be 190 and 109 factories you better believe I would have guys dedicated to making sure the dont get hit. All those delicious kills of fat Jabos and/or slicing and dicing bomber formations, TASTEY!!!!
Now for what factories there would be, would anyone care if the P40, Ju87 or Ki-61 factory got bombed. I doubt it. Factories would probably revolve around the planes that have the biggest impacts ie: Dora, P51D, P47D-30, N1K, Spit Mk9, and yes the La7. Not saying those are to be written in stone, but you get the idea.
