Hull Armor of the M1 Abrams

so one square meter is about 10.8 square foot. so 5.7x10.8=61.56lbs per square meter. 61.56lbs is about 28kg, so my estimation of 30 kg per square meter for only the kevlar wasn’t that far of :)
granted i added extra steel and mounting weight to that which probably would not be necessary.

but i’m a bit confused how they then got 1250lbs (about 567kg) as a total for just the turret.
that would mean an area of 567/28=20.25 square meters, for just the turret. that does not sound correct at all. lets say, 2m tall cylinder with 1m radius. that gives an area of roughly 2m length and 2m width and 2m height (which seams reasonable in my head).
the lateral area of a cylinder: 2πrh gives 2 x π x 1 x 2=4 x π= about 12.6 square meters to cover ALL the walls. lets say you want the roof as well, add π x r^2=π x 1= about 3.14.
so a total of 15.7 square meters.
admittedly larger than i thought but still only 3/4 of their total.

is the turret volume really that big?

This is for the spall liner


And this is the turret basic structure if you want to calculate the turret crew area volume.

rough calculations done in head gets me to about 8-9square meters for the upper turret.
i looked further and the basket is 1.2m radius and about 1.2m high. so (again roughly) 9 square meters.
which makes things make more sense, a total of 18 square meters (from head-math). but then you probably don’t have liner everywhere since it has to be mounted around some stuff.
but yeah, bigger than i thought.

Another photo from book. It said:
Armor
Composite armor, similar to the British Chobham. The composite includes steel, depleted uranium sheets, ceramics and synthetic fibers. is the equivalent of 560 mm of steel armor on the front of the hul


l and 90 cm of armor on the turret.

They dont consider books credible.

that’s… that’s one of the only things except straight up manuals or manufacturer info that they in fact do accept…

Do I really have to put /sarc every time?

yes. its text. sarcasm and text don’t go together and this forum is full enough of misinformed people that many might believe that you actually think what you write is true.

What book is this from if I may ask ? Gaijin can be very picky on some of the authors.

Abrams got a very good suspension to handle more weight and armor!

To be fair, there isn’t enough context to derive sarcasm here. I thought you were being serious lol.

What does that even mean, youre the one misconstruing everything

I said the v3 service date started in 2020, Ayeflyingcowboy said it started in 2018. He denied everything i showed him continuing to clam it was in service in 2018. What am i misconstruing? The service date is 2020.

In may of 2019 the SEPv3 was under FOT&E. It wasn’t set to be issued until 2020? what is the argument here?

The Army received those tanks for testing. The SEPv3 did not enter service until FY20.

The Army received HSTV-Ls too. But they never entered service.

USA winrate is a disaster they gotta do something about it not just sit arround while us mains suffer from spall liners and germany and russia in the same team.

fym this is a devblog about the abrams, and since usa got the lowest winrate in wt history they need a buff asap, china is 53% winrate

even italy got more winrate than us bruh

@arsenal119 now that it’s in the Abrams hull armor forum, the M1A2 SEPv2 would be able to have DU in the hull because the M1A2 has the same armor as the “latest generation of M1A1” (the M1A1 HA, or Heavy Armor) in December 2001:
