These are rough numbers of course, given we’ve made a rectancular plate instead of TES’ actual plate shape, but if you trim off some from that number, you have enough to account for the mine protection, ECM, Radios, etc and ERA.
If you did this with Aluminium however, it wouldn’t even be close.
Okay so how can the backing plates take around 11t of the weight increase, without the ERA, Front Chobam Block, mine plate and the bar armour.
ECM, RCWS and all the electronics and things inside. HEHE
RCWS - 139 KG excluding weapon
Yes indeed
Question is we have one source saying it’s a steel backing plate and one that says it’s an armoured backing plate.
Would a plate made out of aluminum be considered armoured?
Yea, it sure would. Aluminium alloy if we are precise, pure would never be
Because the total TES upgrade from a base Challenger is 12.3
The steel plates themselves are the most dense and heaviest material added in the upgrade, at roughly 11 tons from the calculation. Mind you again - This is as if Challenger 2’s entire sides had a steel rectangle 8m in length, 40mm in width and 2m in height. Your actual value would be something like 9t, owing to how much space our calculated plate takes up, that would need to be removed to represent the accurate shape and size of the plates IRL.
So while the maths can show us the very rough total weight of our object, you’d need to get far more complicated to find out the exact numbers by plugging in the actual shapes and dimensions of the plates IRL rather than running the formula as a perfect rectangle.
Assuming our steel plate is 9t, you can still add ASPRO-HMT, The mine plate, and the electronics onboard and still fit within the 12.3t margin.
Aluminium however, you’d have far too much unaccounted for weight, even if you were being generous. Remember - We’re calculating a perfect rectangle, so the weight of the aluminium from the formula would decrease drastically also.
density is FAR inferion so i would say no. if its counted as armoured it should be steel, if its just something to slap the aspro then maybe it could be aluminium
Can you though? Break down your left over 3.3t there, per item with fairish values each. I bet if thats a steel mine plate thats going to take up alot of your 3.3t budget there.
Also just a fun thing that later iterations of Cr2s carry around
Here on the big green square mount
Its referred to in 99.9% of publically available information as a Steel
Yea, Clansman was taking a lot less space.
Composite material would also be lighter than steel, while providing equivalent amount of protection (per example the warriors rear door was replaced with a composite one I believe) but I the source material that would prove this is equivalent to the source material for aluminum: not really existent
So our maths generates what we see here in blue, but we can shave off everything not in red
To figure out the mine protection weight, we can plug it into the same maths.
Challenger 2 is roughly 8m in length
The mine protection in game is 20mm in thickness
The width of the mine protection is only around 1 meter
Therefore the mine protection accounts for approximately 1.25 tons
9 + 1.25 gives you 10.25, so you have wiggle room for sure. over 1 ton of room actually.
@Gunjob @Legwolf Regarding the add on armour weight, here is a breakdown of the weight increases made to the CR1 during Op Granby. Might be useful for estimating how much CR2 armour weighs:
Here’s what the lines mean:
Do we have a list of the differences and upgrades from 2 to 2H?
Again though, if we use Aluminium for this task, we’ve got alot of unaccounted weight. With steel, our value is closer matching to the total TES package weight.
Here i put external things, not internal
