How so? This is a request for these to be made in game, my first post was so short as I had to get back to work for a bit...
Anyway some rough ideas for these aircraft:
Il-2 early version single seat
Based off of the Il-2m, more powerful engine (need to look up), Grumman style folding wings, up to 6x rocket racks on wings, retains Mgs and 20mm cannon, slightly larger wing span
Later version has rear gunner, less armor between pilot and gunner, same features as above otherwise, truncated to 4x rocket rails, both can carry as heavy as 1x torpedo or 2xfab250s, further weapon load outs to follow in later post or edit
U2
No significant changes apart from addition of arresting gear, perhaps more powerful engine, possible folding wings along lines of swordfish
I-153
Addition of arresting gear, possible wing folding like swordfish, based on 'P' version
I-16
Based on type 24 version, folds wings vertically
I will draw up concepts of all types here soon and post
