Challenger 2 MBT - Technical data and Discussion (Part 1)

because many of L27s values are copy and pasted from L26

no official data, just like about the speed and lenght. So some guesswork and c&p came into play

It seems that 2F late has become our only hope
“Make Challenger great again!”

Can anyone explain why the Challenger 2F’s 150mm (one hundred and fifty) of composite armor add-on is only ~15mm effective?

The base side armor is a slightly angled 38mm. The in-game X-Ray claims “30mm against KE” (a stupidly low figure, equivalent to the basic ERA on an AVRE) - yet it’s actually only 55mm with the composite armor. So that’s a generous ~15mm of effectiveness.

For 150mm of composite armor. While 100mm of “composite screen” on the Swedish Leopard UFP is easily over 200mm KE effectiveness. I would just like to know if this is accurate.

Gaijin’s Magic. Hopefully it changes with the rework thats currently ongoing but we will have to wait and see.

It is wrong, my report is up
As of why, well

it is a long story

The 2F I have no idea. I’m not sure what pack that is on the side but I’d damn well hope itbhas more KE than 15mm…

Then again we all know how the TES/OES ASPRO-HMT debacle has panned out.

It’s funny how composite screens have a 0.16 KE factor when they’re mostly RHA. 0.16. That’s only 3 times better than wood. And external composite armor with NERA, too. 0.10. Only 2 times better than wood.

It just makes a man think… Considering it’s generally Western vehicles preferring to use these over single-use armor. And considering their weight (they wouldn’t make sense if they provided less KE protection than the equivalent weight in RHA) - since something like the PSO package weighs 5 tons…

It’s just interesting to think about these composites that Western tanks put on their sides - the main advantage Russian vehicles have, as their sides are considerably thick and increase their survivability to being outplayed (getting flanked).

Spoiler

I mean, I don’t really like playing Russian vehicles in-game. I don’t think they’re super great. But I do hate how Western vehicles have had their side armor packages turned into worthless plastic baggage.

Well, the composite is mostly some kind of a armour, then nera so some kind of a polymer, glass, rubber or whatever else, and then armour again. Gaijin sadly takes valuses for the NERA part, ignoring the rest

Because of their approach they either are uneducated or not doing proper implementation because of specific reasons that they can’t state openly

They do sometimes make interesting takes

Just look at the steal beasts estimates, those KE values on sides and mantlet look like a dream in war thunder world. The question why we, the player base have to fight so much for very rational changes remains unanswered for me

As that change would make a hull down Cr2 a very hard to kill tank. As for the sides they just dont care i guess.

I know steelbeasts isnt seen as a reliable source but where/what do they even base their estimates on?

At least higher than 30ke

It’s funny, as for the most part steelbeast probably have a more accurate depiction of the challenger 2 than wt right now.

I suspect it comes back to their interpretation of STANAG levels. Gaijin have a sheet of intended protection levels and for side appliqué the values listed are for 60 degree impacts vs darts, which tends to fit with vehicles having protection levels provided “over the frontal 60 degree arc”/30 degrees off centreline

I know finding data on the challenger 2 is basically impossible. But is there really nothing on the nera plates found on the avre, challenger 1 and 2? It seems to be the easiest aider armour to find the values for due to its age.

Steel beasts is a far from accurate representation so don’t even reference it
