It's ridicuolus being attacked by let's say TBF - Avenger planes and the rear (!) gunners make short work with their "little" 0.50 Cal MG of my type IXC... In real life it's hard to believe MGs piercing from 0.303 to 0.50 cal the thick hull of the sub... It is more believeable that the 4 20mm cannons of the Hurricans hurt the sub at some vulnerable spots...
So i just wanna say that the planes cant hit my sub at higher speed ( 15knots+ )with their bombs..., they rather use the rear gunners and sometimes strafing... Once they brought down the hull of my sub with MG fire with a few hits to 8%... http://forums.ubi.com/groupee_common/emoticons/icon_eek.gif

Well, ....I agree that this case sounds a bit extreme: .....but in the same breath, I have to say (having had "hands-on" experience) that you would be amazed at the effectiveness of the old "Ma Duce", when loaded with API ammunition!

50. cal had AP ammo in default loadout... Dont tell me that it could pierce 50cm+ thick stainless-steel side-hull of any sub... It was designed for air defense... i mean the rear 50cals, not for ground (sub) attack...

I think you probably mean 50mm thick ??? http://forums.ubi.com/groupee_common/emoticons/icon_cool.gif

Lol, I'd love to sail a sub with half a meter thick steel hull.. Or, rather not. I don't feel like a meeting with Davy Jones just yet http://forums.ubi.com/images/smilies/88.gif

On a serious note, I read a story written by a pilot of an ASW plane near the American coast. He said those rounds were like spitballs, since they were: a)Not issued AP rounds for some reason and b)They bounced off anyway.... So GWX took it a bit too far there, methinks...

First, let me say that I'm not posting this to "correct" anybody: .....The original poster asked an historical question, and I happen to have the information.

Both the TypeVII and TypeIX pressure hulls were fabricated from 18.5mm galvanized steel plate. Only the TypeXXI pressure hull was made of 25mm stock.

There are two armor piercing rounds available for the .50 cal MG that have the capability to perforate the pressure hull of a TypeVII or TypeIX; but only at close range:

1) The M2 AP (Armor Piercing) round which will defeat 19mm of armor @ 500 meters.

2) The M20 API-T (Armor Piercing Incendiary Tracer) which will defeat 21mm of armor @ 500 meters.

It's important to note that the penetration capabilities of these rounds drops to only half of the above values at a range of 1200 meters.

In spite of that apparent good news, you have to remember that your pressure hull is not made of armor plate; ...but rather "ship steel" with a tensile strength in the neighborhood of 74,000 psi, whereas most WWII vintage armor plate had values in the 100,000 to 110,000 psi range.

So the answer to the question is "Yes and No". The only scenario where you would have to worry about hull damage would be low level strafing runs. (....And then only if the aircraft had been armed with the appropriate ammo for "boat hunting".)

I agree, that I would not want to be on the receiving end of an M2. It will chew up anything short of a Main Battle Tank.

And probably more fun to shoot than any weapon I every fired. Actually, I can call the M2 a gun, can't I?

My experience with the Cal.50 was with the Commanders Weapon Station (CWS) in the M1 Abrams Tank. It had a max range of 2000 meters due to sight limitations. I could still chew up APC's or light skinned targets. Funny enough was that you could not fire at enemy troops (Geneva Convention) but you could use it against material. I believe ammo belts, canteens, helmets are all concidered equipment. The field manuals shows how to engage airborne tropps, note: aim below them, they can't go back up.

Heh, Heh! My weapon was the M85 Cal.50>>fixed head space and timing. Fired through 10X sight. Could never understand why the Army didn't fix a thermal site to it only IR. We normally fired APIT subcaliber through the main gun. It was a sabot type used by the Isrealies turning your balistic computer thermal Gunners Primary sight into one hell of a sniper weapon. It was simply a 120mm shell casing with a bolt action reciever mounted in it. The whole thing loaded into the breech with a sub designaton code for the Cal.50 round. This gave the Cal.50 a maximum range of 4000 meters. The balistic computer corrected for superelevation and drift. Just think of that poor enemy soldier smoking a ciggarette when puff your buddies head explodes...Not that ever happened.
