Idk if I’m seeing things at this point, but how is the outer NERA 30mm thicker whilst appearing smaller on X-Ray?
I actually bug reported this one, and it didnt last long before they just shut it down with no explanation whatsoever

Also merkava use slera not nera
I´d say thats a partial description. A more complete one would be to say that Merk 4 armor is a hybrid between passive and reactive armor, whereas the SLERA/NxRA represents the reactive part of it. I recommend reading my article for understanding this.

Yes, both modules look like they have different thickness but the part closer to the turret has been so far very difficult to measure for lack of adequate pictures.
But the section that hinges forward indeed its about 150-170mm thick so Gaijin got that right.
But the armor value is wrong also the engine should absorb spall and eat some rounds toogether with spall liner
That goes without saying. Though the limit I estimate for the part that hinges forward, for what it can stop on its own without the projectile advancing to the engine itself are APFSDS up to DM33-BM42 level. Anything with better penetration than that will go through and at least will kill the engine.
Still, an improvement over the current ingame situation.

How’s the bug report going (If at all) :D
Not yet. Next step is an additional article with other patents I’ve found after the first one. These support many of the thesis present in the first article.

There is any chance the hull could stop bm60?
Even with sacrifice power pack

Highly unlikely, even at long ranges. I estimate the UFP armor to be equal to about 480-500mm. So I don´t think its likely to stop Svinets even sacrificing the powerpack. If Merkava 4 armor modules were upgraded over the years (of which there is no evidence yet) then perhaps nowadays it can.
If the ufp is equal to 500 mm so the power pack should stop the the round
Dont forget u have also 30mm between the power pack and the crew
love random people “estimating” how effective modern tank armor is in millimeters at stopping something. give real sources, because personal opinions about how effective something should be like that arent worth anything.
Bruh read his article
unfortunately were gonna need something more than a person who makes a blog and “estimates”.
anyone can make a blogspot.com website and take a few photos and start estimating things in millimeters. doesn’t make it accurate or reliable source. its just a personal opinion.
we need better sources than what the blogspot has
Well you could try, like I did, spending hours and hours searching for patents and trying to make sense of them together with other kinds of evidence. Until you do that work, just keep in mind that “speech is silver, but silence is golden”.

Lets be fair here. If we go by my interpretation of the Rafael patent, Merkava 4 armor effectiveness vs LRPs is fundamentally dependant on the length of the latter. At the UFP of Merk 4 we can fit up to 120mm worth of Orlite-made composite plates, which sloped at 74º yields up to 435 composite LOS. In other words, it will fully defeat APFSDS whose penetrator is up to 435mm in length, or 450mm if you want to round that up a little to account for other features described in the patent that can enhance the volume effectiveness somewhat.
Now when you go check which APFSDS have that kind of characteristics you find that BM42 is just that same length so I guess its absolutly possible that the actual requirement was defeating that exact round without sacrificing the engine. Hence when I translate this capability into RHA KE I round to “450-500mm”. But here 500mm is but a ceiling, a high end for my estimation.
Regarding Svinets, the UFP alone is very much insufficient to defeat this round. How many more milimeters of armor do the engine, the spaced cavity and the back plate provide? Thats very difficult to estimate but in any case I´m not optimistic.
In addition, BM60 has some extra capabilities that can´t be expressed in raw RHA penetration numbers. Just like DM53 and other have “special performance” but armors such as ERA (not yet modelled ingame but it should), BM60 may be particularly capable against Merkava 4 armor (and others).

Honestly, you’re doing god’s work by collecting all of this material for the Merkava armor issue.

you do understand im not making any claims unlike you. you do a lot of research but so does everyone else who comes into a different conclusion
what gaijin needs to model is merkava’s armor being damaged after taking a shot. it gets significantly damaged because of the design choices unlike something on abrams
I´ll be glad to read anyone else´s research on these same sources and/or adding new ones.
