Why is it so hard to find the armor thickness on modern MBTs?

Me too....least bothered 'bout the count of Rounds. If its be 6 trillions of rounds....no matter,assuming as per requirement.

What I mean is all bout the health-hazards of the related personnel and Obviously of next gen[by the exposure]. Since Both Are Precious as well as Beloved to us,not a much worried Matter...?//?

I might sound like an ignoramus, but won't depleted uranium still display some amount of radioactivity?

 

One thing about being the son of a proessional metalurgist is being able to ask questions. Some twenty years ago I asked about DU armour. I was able to learn that it was tried and found to be impractical. Sure it is dense, but it was "too soft". Softness is fine for ammo, like lead, but poor for armour.

No, modern vehicle armour is a secret wizard's composite of "laminated plates" composed a a variety of materials. And UD is a myth. It is more likely to contain layers of ceramics, of steel-alloy, of some sort of rubber, then aluminum, then more ceramics. These modern wizards can conjure ceramics tougher (in some ways) than steel.

BTW, Tungsten added to steel is for heat-resistance, not hardness.

 

Common rookie mistake. Yes, DU still decays, just more slowly. But here is a secret: hit DU hard enough and watch it catch fire. And incoming shells tend to hit armour rather hard.

You do not want your own tanks to ignite, so DU is out.

 

They want to keep their armor thickness a secret, so the people fighting them won't know how powerful of a weapon they need to design to destroy the tank. I am betting in world war II or other wars, they didn't make it public knowledge what thickness the armor of their tanks were either.
