Anytime you hit a section of piece of steel with the force of a bullet, you are weakening the whole piece. The force of the bullet is transmitted through the entire structure, stretching and warping it. The next bullet which hits, strikes a weakened structure.

And to suggest only one bullet could hit a seat rear in a single burst is inaccurate, I have read a number of accounts of surviving pilots coming back with multiple hits on their armoured seat back and with it cracked and warped.

Well until you will have a NASTRAN level material engineering code in Il-2 this is rather theoretical (as it is in real life IMO) so we will have simplified model where the armor plate will be good as new any time it is hit... so can we just skip it and get back to the point?

Does the Il-2 Bf 109E armor modelled or not?

A few reports on shot down 109E inspected by the British on the ground.

If you are all talking about this (see picture) then it was installed on some E4 but some pilots asked to remove it becaue it did restict their view.

And it is never a perfect protection against a hit from nearly behind or from the front! stupid is it not?:evil:

I read once that the 109 did have pilot protection armour. Only reasoni do remember is that some pilots removed the head protection plate as it prevented rear view and that at later date thiswas changed to bullet proof glass behind the pilots head due to this reason

Very late in WWII Me 109 were fitted with plexiglass in the 1940 only the BF109 E4 even if some early version were retro fitted.

IRL .30 cal AP penetration is quite impressive, even .30 cal ball ammo easily penetrates pretty thick steel plate. I suspect for air-to-air, over penetration may have been a problem, unless something critical is hit like the pilot (or his "armored" back rest), engine block, control cables, etc. Otherwise rifle bullets are just punching neat little holes in the structure.

What are you basing this on? American .30 is not the same as British .303. Problem is in reality armor plating is rarely the first thing the bullet hits. See the following from: http://www.quarry.nildram.co.uk/BoB.htm

Based mostly on goofing around shooting M2 .30 cal ball (AKA .30-06) and .303 Brit, which have very similar (negligible differences?) ballistic characteristics.

Seems if true armor plate was used (vice improvised plate steel), and/or the bullet hits at an angle (vice 90 degrees), then I guess penetration would be limited. But when I think of aircraft construction, I think of aluminum, which I imagine any .30 rifle bullet would penetrate with little loss of energy. I find it notable that at 200 yards 6% of .303 AP penetrated the 60 degree angled armor. What percentage of the rounds reaching the armor were stopped by it? The report also doesn't address the ultimate fate of the AP rounds that where deflected by the aircraft structure and missed the target armor plate. I assume many continued on to penetrate other portions of the aircraft?
