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

Just for my sake, when’s that from? My understanding is the development of the armour arrays on CR2 were completed in 1994, presumably capable of defeating the project “next generation Soviet tank” (or Russian by that point)

Or maybe perhaps they were telling the honest to god truth.

It’s not like the crews lives matter based on what’s said or anything… wait…

I prefer my interpretation, but you keep believing what you want to.

Well, that’d entail having armor that has KE equvialency much greater than 1.0 (in order to have better armor than the Leopard 2, that, by 1993, had armor capable of providing ~750mm KE on the hull’s glacis, including the add-on), but that is, gently speaking, physically impossible lol (unless of course, your armor is nothing but a big fat slab of DU, which it wasn’t, seeing as it was still being called “Chobham”).

@Godvana’s intepretation makes a fair bit more sense.

Chobham is just the name used by UK to any type of composite. They were just so proud of the fact the made Chobham, and that it was good, so they started calling every composite Chobham. Name of the Cr2 composite is Dorchester. For example, they called composite in ASPRO-HMT “Chobham-like”

there’s also the possibility that they were talking exclusively about mass efficiency or general array composition, rather than the total in-situ protection. You can make a lot of things sound better by focusing on one specific point of comparison

I am aware, but my point is that it’s straight up impossible to exceed Leopard 2s Improved protection without turning to the most extreme of measures (Chally 2 is limited by the available armor space for one), where all the armor’s replaced by nothing but plates of DU, which, for one, would absolutely ruin the armor’s ME (as DU is extremely dense and thus heavy), but also make the protection imbalanced, as DU is better against KE threats than against CE ones (the glacis alone would weight 16% of CR2s total mass, i.e ~11.6 tons based on napkin math, if that were the case, as it’s pretty much the only way for it to achieve TE greater than 1).

Im not gonna argue about the protection, i cant be bothered tbh. Just pointing out that it being called Chobham means nothing at all, other than it is a composite.

I mean, it kinda does in that case, since calling it a “composite” indicates it is made from at least two different things, but a bunch of DU isn’t that ;P

Anyhow.

You know, RHA-DU-RHA is already a composite.

Meh.

Hell, given how anyone and everyone uses it, it could mean anything that isn’t generic RHA. It’s literally used to mean “composite”

What, claiming it’s better protected than it actually is…

Because that sounds like lining one’s self up for a whole lot of very angry questions should it fail to do so.
I’d entertain the theory a bit more if he made it sound like the MoD were being politically pushed to choose British and that particular line in question was written to sweeten the deal (and, let’s be fair, they probably would’ve been doing just that. they had plenty of reasons to)
However to suggest it straight up didn’t meet the requirements (which would seem to be the implication here) is a level of fiction and fantasy I can scarcely believe, and I seriously doubt you can too.

“Yeah, why is it called Chobham, if it’s actually Burlington, Dorchester, Epsom, and Farnham?”

Oh god…
Keep the composite Chieftain out of it.

In all fairness, the original SR(L)4026 requirements for the Chieftian Replacement had indeed been quite unimpressive at first compared to the requirements the Germans and 'Muricans set for their own projects, and even later on, they weren’t standing out of the line, remaining actually grounded in reality :D

Besides, pretty sure he wasn’t suggesting that it didn’t meet the British requirements, just that the claims of it being the bestest of the best + ever better are boogus (trolling, in other words).

“Yeah, why is it called Chobham, if it’s actually Burlington, Dorchester, Epsom, and Farnham?”

I give the MoD about 10 years to start calling just air between two steel plates “Chobham”.

Umm, that was already done tho…

Let me present to you, Chobham block at the bottom of the side plate

It is either missing some filler, or it was just air.

Currently, we are taking AIR as the real version.

You can’t see my face, but I am looking very disappointed rn that this has already happened and that they unironically called spaced armor “composite”.

I mean to be entirely fair, it being incompatibke with NATO ammunition probably kicks it out of the running for that title. That and the on road mobility, though Offroad and Cross Country mobility, in contrast, is by all accounts quite good. Though on the bright side it doesn’t use a Gas Turbine (which is, according to some of the Ukrainians, a pain in the arse to maintain)

I mean the MoD have less clue than we do so that wouldn’t surprise me

Chobham armour here we go :troll:

There is also a possibility, that the middle plate is made from something else, but as we lack data, current understanding is: RHA-AIR-RHA-AIR-RHA(alluminium per gaijin)
