The 1944 model was identical to the 1943 model in all aspects but the upper plate.<br /><br />This is a further design that changed all of the abovementioned aspects, as well as keeping the improved upper plate.RRDNissehttps://www.blogger.com/profile/18431890564344275638noreply@blogger.comtag:blogger.com,1999:blog-5030145265861917845.post-62670098744505289722016-06-27T16:14:58.181-04:002016-06-27T16:14:58.181-04:00The ranges given here are likely calculated for th...The ranges given here are likely calculated for the purpose of modernization comparison and not reflective of actual performance.<br /><br />-from another soviet document:<br /><br /> "Front of the hull<br /><br />The design of the front of the IS-3 hull provides superior shell resistance compared to the mass produced IS-2 hull, excluding the front sloped roof of the hull.

This may be similar to the Tiger I, which had a maximum mantlet thickness > 200 mm but which wasn't representative of the whole; maybe 130 mm is something like a "weighted average".Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5030145265861917845.post-79258770257575635952014-07-07T14:36:49.133-04:002014-07-07T14:36:49.133-04:00Either way, it cannot be penetrated.
