How much deck armor would the 100 kg (220 lb) SAP bomb penetrate?

I'm guessing 30mm.

It depends on altitude (or more precisely striking velocity). Italian anti ship bomb 160P 90mm from 4500m, my calculation from 3096m(10000ft) is 63mm . This is a bomb with only 24kg explosive so 15% of explosive so can be considered an AP bomb.

Thanks for the reply. I'm unfamiliar with the 160P and didn't know Italy even had an AP bomb. I thought the 100 kg SAP was the closest? When was the 160P available? Size?

It was not in stocks at beginning (10 June 40) , i have no date but l probably still in 1940. I have it with real 163,5kg but no dimension or drawing data.

By 1943(June) they had several AP, see this about their tests in Cant Z.1018 - Note that FFF are circular torpedo and not bombs.

From a document from 01 September 1941 Notiziario Armamento N.5 , so probably operational mid 1941, you can find the document in NARA T821-0481. In same document there is also defined how to put them in S.79 100kg drop bomb system, so in theory the S.79 could also take 12.

Thanks! Do you have any penetration info on 100 kg SAP of 1940?

 

[Dili]

It should be what you said, maybe a little better but just a couple mm, from 3000m.

Assuming level bombing not dive bombing
