Anti Tank Performance

Data on the armour penetration capabilities of Italian artillery is hard to come by. I've found another site (http://miniatures.de...nt/shellsI.html) which provides armour penetration details for quite a few weapons at 100m against vertical armour. However I've been warned about the accuracy of the information on this site. For example it says the Italians had a HEAT round ('Effeto Pronto') for the 65/17 Infantry Gun which could penetrate 120mm of vertical armour at 100m. Since a short German 75mm gun only penetrates 100mm at the same distance I'm suspicious.
Any data on the armour penetration capabilities of Italian anti tank guns, tank guns, anti aircraft guns, field and medium artillery or other web sites/books where I could find the data would be appreciated

You can find a lot of data on the good book of Cappellano:
Le artiglierie del Regio Esercito nella II guerra mondiale. Parma 1998, Albertelli ed.

It's very difficult find data on the AT capability of EP (effetto pronto)round. Pignato in a book about the medium italian tanks reported 70 mm for the EP round of 75/18 gun mounted on the self propelled gun. There are no sure data on the AT capability of 65/17 gun.

Best regards

Does anyone have information on the performance of the 47/40 cannon used on the M15/42? Also wasn't this used on the semovente based on the L6 chassis at a later point? Was it ever used as a stand alone at gun?

Thanks for answering the 20 question bit. ;)

Just to add someting to this old thread

It seems the first 200 EP 75mm rounds were available in November 1941.


Post by Attilio60
Nel già citato articolo sulla battaglia di Bir El Gobi pubblicato
sull'ultimo numero di Storia Militare l'autore afferma che alla
artiglieria italiana vennero consegnate in tale occasione 200 granate Effetto Pronto di
calibro 75 mm.
La fonte di questa informazione e' il diario storico del comando divisione
dell'Ariete, che alla data del 12 novembre recita:
"Vengono assegnati n.200 proiettili da 75/27 ad effetto E.P."

Post by Attilio60
Nelle mie fonti la distribuzione di tali munizioni in Africa Settentrionale
avvenne solo dopo i primi mesi del 1942.
Le tue fonti (quali sono?) probabilmente non sbagliano di molto: mentre
in novembre fu consegnato un numero non elavato (200) di proiettili a
un'unita' d'elite come l'Ariete, probabilmente solo nell'anno successivo
(con l'arrivo dei nuovi convogli) la diffusione avvenne in modo piu'
capillare e in quantita' considerevoli.

I have this for EP rounds. Not necessarily Africa.

65/17 : EP round available in Spring 42
75/27( and 75/18 for Semovente) : late 41
100/17 :second half 42, EPS in May43
105/28: the round was called mod.43 so i suppose it arrived in 1943.
47/32: i have not the data handy since it was a useless technology due to small caliber projectile.

Do we know in what sort of numbers each type was available in Africa and when (apart from the 200 listed above).

Then some comparative penetration figures would also be useful.
