Well, heres my suggestion.
In world war II they had TB, DB, FP, and recon planes.
There was more than that.
Like carpet bombers, and planes with more torpedos.
Like the B17 Flying fortress. Carpet bomber.
My suggestion is that you can load these, which requires like 500 space per plane. and you can only launch one per squad.
Then have guns in front and rear to defend themself, but they cant take that much. So you could escort them by selecting your squad and right click on the bomber to
How to control:
Just fly your Carpet bomber and press . to drop the bombs, which are like 10. They arent that powerfull like 1 db.
Like normal HE damage is 2000 for one bomb, its 1000 or 500 for 1 bomb. You can load your carpet bombers with bombs but they are less powerfull
So when you fly your bomber at max. height and you press the divebomb button you should release the bombs.
They are slow, but can take way more AA shells than regular planes. The altidude is just like DB's.
Torpedo bombers how to controll:
Just the same, they carry 2 or 4 torpedo's and they are bigger than the other tb's just like a recon plane , like the catalina.
You drop the torpedo just as you drop it regulary. The torpedo's are a little weaker. and you can only launch 3 per squad with a maximum of 9 in the air.
This was my idea, it took me a few minutes to work it out, hope you guys like it.
Help is welcome i could make more of this if people like it i can make screens with my own planes to show what I mean.
