Hi Frank,
Obviously you know, the penetration capacity of the bullets depend on their velocity at impact. So when you are saying \"...could easily penetrate the outer...\", distance and end velocity are the determinating factors.
Outer skin parts were as thin as 5mm (a tad less than 1/4\"), pressure vessels of both type VIIc and IXc 18.5mm (3/4\") with VIIc41 22.5mm (7/8\").
Do not know of any case, where A/C 50 cal machine guns actually penetrated pressure hull. Could do a lot of damage to the flak crews etc. Rgds, RB
