What about resilience to HEAT jets? Do the air bubbles help with that or is the mitigation negligible?

If the foam is filled with something (fuel, maybe) then it could provide decent HEAT protection.

 

Against APFSDS it won't do much.

Metal foam should just act like a whipple shield against HEAT (i.e. probably quite good against the jet tip)

But isn't a HEAT jet quite different from something floating/flying around in space? Sure the speeds involved might be the same, but if you encounter something with the length of a precursor (~5 cm) in space, you're still royally fucked I think.

For as far as I know diesel filled armour only works when it's confined:

If the shockwave doesn't/can't reflect back to the jet it won't slow it down.

      hello everyone!
      so i read that the T-90 shares the T-72B turret , thus BDD armor , however this documentary (?) : https://www.youtube.com/watch?v=lKGv5JQBTI8 says "aluminums and plastics".
      is this any legit? did they like , keep the t72b cavity design and change the fill?
       
      also , did the combination on new welded towers change?

      Most historical arms and armor were made of metal, leather and stone.  This is the thread for historical weapons and armor made of weird shit.
       

       
      This is an example of armor made from the Gilbert islands made of thick, woven coconut fiber.  The helmet is made from a pufferfish.
       
      I've seen a set similar to this in another museum.  The woven fiber body armor looked like it would be reasonably effective.  Coconut husk is pretty tough and the vest was very thick.  I wasn't so sure about the helmet.
       
      The Gilbertese were also the foremost users of shark's tooth weapons, although other Polynesians used them as well:
       

       
      Several historical examples I've seen are these strange, branching designs:
       

       

       
       
      Polynesians were not the only ones to use teeth in their arms.  The Mycenian Greeks made helmets out of boars teeth.  One such helmet is described in the Iliad, and there are a few archeological discoveries of such:
       

       

       
      And finally, a club used by Inuits made from the penis-bone of a walrus:

      Too often technology is portrayed a steady, linear series of more or less inevitable improvements.  This is an easier illusion to maintain if you don't know anything about the subject.  In fact, the history of technology is littered with insane, unworkable garbage.  Things that didn't work, barely worked, might-have-beens, things that would perhaps be worth revisiting, things fit only for ridicule, and some things that make no sense whatsoever:
       

       
      Yes!  Terrify your enemies with your new gunspoon!  Note the direction of the trigger and the direction of the muzzle.  What the hell were these even for?
       

       
      Attaching solid fuel rockets to a bicycle!  We totes verified this idea in Kerbal Space Program, it'll be fine.


       
      An external combustion motor that uses ether instead of steam!  Nothing could possibly go wrong with this!
       

       
      A turbine powered by boiling mercury!  There is definitely nothing at all that could go horribly wrong with this!
       
      Douglas Self's Museum of Retrotechnology Site has all of these wondrous devices and more.  Feast your mind on the retardation of the engineers and inventors of yesteryear, and be amazed that anyone is left alive on this planet.  "Steampunk" ain't got shit.

      This is wonderful.
       
      I learned:
       
      1)  The leo 1 had poor hull armor, but excellent turret armor!
       
      2)  Chieftain's armor was 16 inches thick!
       
      4)  The T-64 was the Soviet's own version of the leopard(?!)
       
       
      Actually, the materials science stuff seems solid, and jives with what I've heard before (but how much of that is people repeating this article?).
