Challenger 2 MBT - Technical data and Discussion (Part 2)

Accepted 2 years ago… just sad

impressive the mind bend from the devs to not accept it, even more considering the stanag 5 is the ERA block itself (as light vehicles are also shown in the ASPRO-HMT brochure background, leading to believe the era block itself is stanag 5), not even having the double composite backing taken into account (as it was much more the british adding it rather than being sold with the ASPRO-HMT)

Should’ve been closed 2 years ago. After rereading his claims and the documents cited, its nonsense. I’ve closed it.

Wouldn’t exactly be combining anything then…

It was 1800 on dev. Went down to 1300 after widespread complaints, then became a ROMOR copypaste for a while on the basis of “we don’t know what this ERA is, so it must be ROMOR equivalent”. Now we get 500 (at least with tandem protection, not that it counts for much.)

But obviously not the RPG which it was slapped on in response to… cough RPG-29, 800mm+.

Gaijin doesn’t like sources from Ukraine. Iunno why, they’re like the best sources on hand.

No reason why the exterior of the protection array would be sensitive. It’s basically just removing the paint. Plus I know no self-respecting Ukrainian crewman would photograph sensitive items.

Same reason every single block of composite in the tank has a different protection multiplier (UFP, cheeks, turret sides, addon, LFP addon) and many have a limit to their protection. I have no clue what that reason is though and it’s absolutely absurd. I will never quite get how gaijin believes a 25+200+80 array (UFP) provides only 150mm less protection than a 50+50+400+38+110 array (cheeks), and about 150mm more than a 25+230+60 array (turret sides) (all RHAe KE values. Numbers are even weirder in CE).

Possibly one of the most restricted things on the vehicle unfortunately. There are reasonable guesses out there but they’re even more vague (by a large margin) than the ones on Abrams.

Tandem protection doesnt mean squat when atgms will over pressure you through it. The amount of bmp 2m missiles that have just killed me by hitting around the track area including the era just infuriates me. Not even a one off, basically every time they shoot at me its either that or theyll hit my cheek and over pressure me… And then youll have the doombarn just get a hit if you hit anything but their roof.

Not even. I’d be alright with the occasional overpressure if the ERA at least worked. It couldn’t even stop a konkurs alone, ignoring the fact that half the idea of the challenger’s protection is multiple hit survivability. I will say part of gaijin’s error with ERA is irl it is not a set value, but often estimated as a percentage reduction in performance. ERA that removes 80% off a tandem konkurs (like 480mm) should also remove 80% off a tandem khrizantema (like 1000mm). Most modern ERA is measured against HEAT in the range of “>90%”.

It seriously does not help that gaijin has some really weird obsession with making everything fall off. I don’t know why it doesn’t do this on other tanks, but EVERYTHING falls off. The ERA falls off when hit, the NERA falls off when hit, the damn cages fall off when hit. The composite block underneath the ERA falls off when hit. The goddamn steel backing for the entire ERA array falls off when hit, with sufficient impacts the LFP block can fall off when hit (I have a screenshot i posted here a while ago demonstrating this, because I was just in shock that they even made that possible). There is no reason for any of this to come off except maybe the ERA, and there’s some evidence saying it’s SLERA and probably shouldn’t too.

I’m half convinced HESH as a whole is set up as copypaste APHE. I was playing the BN earlier, put one on the floor about 50cm ahead of a pantsir. Not even a hit.

I don’t know about you, but 6.5kg explosive 50cm away from a truck should probably do something.

They’ve said they fixed the issue where it was one or the other. HE or HESH effect, but i dont see a change at all. Ill still not over pressure a guy because he has an “air gap”. Itll be some track armour on the front of his tank. They should give HESH rounds hull brake to make them usable, maybe with big he rounds as well to stop them having to put big he slingers so low to compensate for their inconsistent damage.

Hullbreak is generally a more accurate description for HESH. You should look at the 165 HESH vs tiger 2 trials, where they literally caused the entire chassis to bend in one photo. If they won’t make spall bounce, at least allow the shell to break the damn vehicle.

Weirdly I find 90mm HESH to be fairly reliable on the overpressure front, even got a twofer the other day in the Aubl74 against a M18 that overpressured the BTR-ZD behind them.

I know about a specific member of the British MoD who did that and posted it to Instagram. God I hope he makes his way to a HM Prison.

I’m half convinced our spall liners are just cosmetic.


Leopard (same side composite thickness, same dart) for scale. I don’t see how the disparity can be so big.

Also minor addition. Iron fist doesn’t cover the entire vehicle. Sometimes I feel like my goddamn APS is cosmetic too because ATGW to the roof or to the tracks that instantly oneshot me with magical overpressure are just ignored because for some reason the actual coverage is smaller than the vehicle’s hitbox?? Literally just died to an ADATS because it hit my roof and oneshot the entire crew through the spaced block, through the spall liner, via overpressure. Ignored by APS entirely and its HEAT charge didn’t even hit anything.

That’s Britain. When the CR2 got their “spall-liner” I sarcastically said that it was actually a cosmetic thing to give Gaijin to say that the CR2 isn’t improperly modelled. Looks like I was right

Everyone should take a gander at this: Challenger 2 Overhaul

They fixed this issue on dev. I’m honestly somewhat shocked.

Edit: appears that the APS is weighted better too. Two engagements from the front will use left, then right, instead of simply wasting the left charges first.
