Wonder what effect it would have on the stream from a shaped charge?<br /><br />Also, on the holey armor, wonder if it has any enhanced effectiveness against a shaped-charge or self-forging fragment?Firehandhttps://www.blogger.com/profile/04562365951182027709noreply@blogger.comtag:blogger.com,1999:blog-8515829.post-31177333590298681942010-03-22T09:37:45.746-07:002010-03-22T09:37:45.746-07:00K, I never overestimate the ability of a reporter ...K, I never overestimate the ability of a reporter to f*** up what he's been told. However ... the descriptions I found online of "Super Bainite" suggest that it's an enhanced version of bainite steel, or perhaps a new way of making bainite steel. <a href="http://aciers.free.fr/index.php/2009/01/07/le-ministere-de-la-defense-anglais-annonce-le-devellopement-dun-acier-super-bainitique-qui-constitue-le-blindage-le-plus-robuste-au-monde-us/" rel="nofollow">This link</a> is the best description I found.

This 'forcefield' armor seems to be something different. <br /><br />But I think the coolest thing in that article is the third type of experimental armor it mentions, the "Super Bainite." I would <i>never</i> have thought that putting holes in armor plating could improve its protective rating, but the concept does seem to work.wolfwalkernoreply@blogger.comtag:blogger.com,1999:blog-8515829.post-72512895674794665372010-03-21T19:12:09.590-07:002010-03-21T19:12:09.590-07:00Their description is terrible.

When the RPG metal bridges the gap, it shorts out the voltage, and the spark blows up the projectile. That spreads the impact over a larger area of armor, so it can no longer punch through. It's basically a weapons-grade bug zapper.Anonymousnoreply@blogger.com
