US soft RHA is optimized for lower hardness realms. <br />Notice the criterium of backspall =4.0 times cal/diameter as borderline of acceptable soviet armor quality. Most other services had the limit at 2.0 cal/diameter for backspall, instead (acceptance limit). critical masshttps://www.blogger.com/profile/02366274198749901618noreply@blogger.comtag:blogger.com,1999:blog-5030145265861917845.post-87402611991517021092018-06-28T13:15:06.901-04:002018-06-28T13:15:06.901-04:00Whoops, my bad, I keep forgetting the dates.

The upshot ...What's the date of this document?<br /><br />The upshot is that the US was dumping defective armor plate into Lend-Lease. No big surprise, I suppose. Wonder if this was manufacturers sneaking things past Uncle Sam so that they weren't "wasting" money and resources, if the government knew but didn't care, or if the government knew but making Lend-Lease quantities was more important than quality.Chits 'n' Thingshttps://www.blogger.com/profile/01819307975178436315noreply@blogger.com
