First two sources mention a frontal armour upgrade but not where on the tank - still likely the turret
Veterans Affairs PowerPoint presentations are hardly a good source, they’re made by doctors and lawyers, not engineers. That one you posted also conflicts itself - it claims there’s DU in the hull, then shows a diagram that implies it’s only in the front of the turret.
fortunately we have proof for the SEP v3 because I believe the armor got visibly thicker
when a source says frontal armor upgrade and turret side armor upgrade its safe to assume frontal includes the hull, that might not be on the source you were responding to but that is said in other budget sheets
But do you have values for that increased armor thickness?
For all Gaijin knows they just needed a bigger volume of armor the get the same protection as the DU armor, just like for all Gaijin knew 3rd gen DU armor offered lower protection than esrlier DU armor.
So the turret front and sides, nice find!
Then why would they show an image of the turret front to denote the “frontal” upgrade and not the front of the whole tank? Same with the “side” diagram that clearly just shows the sides of the turret highlighted.
different upgrade package at a different time
What’s the source on this one out of curiosity? Because I’m not getting much of anything via reverse search
Still the same. US tanks don’t have spall liners, no turret armor, no hull armor. It’s hilarious playing the Strv 122 with spall liners and working turret/hull armor and then vsing any variant of the Abrams and being able to frontally pen it anywhere.
