About the 109 glas wing....

Did a little bit of testing myself, shooting at Bf 109 G-2 using Spitfire IXc (.303 cal) and then IXe (.50 cal) as I can be fairly precise using these individual wing guns. Ranges varied from 50 to 250m.

 

There are definitely improvements here so I'm thankful for these, the .303 calibre isn't able to cause premature wing failure as it did before, at least with the Bf 109 G. It seems to be able to absorb a lot of these rounds (+100) even at point blank range so that's positive news.

 

Using the .50 calibre on the Spitfire IXe and then later the multiple wing guns of the P-51B it was taking about 50 to 60 rounds to cause wing failure, and perhaps half that to cause the outer wing to crack and fail... so can confirm similar results to what Roland_Hunter is getting. I think this is a pretty reasonable improvement. 

 

In terms of the hispano cannon (Spitfire, Tempest), I'm getting roughly 4 to 5 hits to cause the wing to fail (not including aileron being blown off). These shots tended to be spread across the wing, and I would argue that's still too few. If these hits were all within a concentrated area it would make sense, but I wasn't that accurate... it should be roughly double that number. For reference, a one second burst with a single hispano will fire roughly 10+ rounds a second, which also happens to be an often quoted firing time mentioned in combat reports when describing wings being shot off at close range. This would make sense as you're only likely to get one wing mounted gun on target like that in many cases.

 

Final thing, a mere two well placed hispano shots on the outer wing were able to cause it to badly crack, bend and then detach (see below), this again seems a bit excessive. I would argue that number should be doubled... as it's not just the wingtip that detaches but a substantial section of the wing, making the aircraft unflyable.

During testing (though I ask others to confirm as well), it took 15 hits with the MG151 to break off the Yak-7/9's wing at the wing root, and the same number of ShVAK 20mm hits caused similar damage. Why does the MG151, which contains 4–5 times more explosive material, cause the same amount of damage as the ShVAK?

Additionally, although there's a fair amount of RNG involved, it's possible to break the wing at the Balkenkreuz with just two 20mm hits.

Maybe it's because a greater proportion of the ShVAK's rounds are AP? and (rightly or wrongly) it's the kinetic energy they're using rather than the chemical energy to calculate the chance of damage to the structure. 

 

Irc with ShVAK it's 50/50 HE to AP, whereas the 151 is 66/33
