  1. Armoring tanks is always cost effective during wartime. A single tank's price can buy several dozen armor packs. So it's not that.

    Besides, they're likely to receive a monetary boost from the Sultan.

    Lack of experience? Surely they're functional enough to realize they're being mauled out there. And functional enough to make a single source purchase that requires no integration works.

    It's just that not many approve of their way of thinking, as some may put it.

    Erdogan is practically a Sultan now, and Turkey's not-so-successful invasion of Syria is seen as a non-necessary expansionism at the expense of the local populace. Germany just happens to be a strong supporter of the Kurds, as I understand.

    Austria(?) recently announced that they refuse to provide technology for Altay's planned new engines.

  2. Indeed weight savings. The armor is already very heavy for them, and the Leo 2NG affords less hull side protection, while the 2PL gives up on any form of hull armoring. 

    Probably why also neither of them bothers to armor the roof. The Leopard 2NG as it is, weighs 65 tons.

  3. quick guesses: primer failure resulting in a dud. Although would still require an open breech.

    excessive barrel bending causing fuze setting inside the barrel.

    Cracks in the breech causing rupture.

    Could be either, or none.

    Oh and that's a T-55. Old platform coupled with poor maintenance can have deadly results.

  4. That's not what I meant.

    I meant that the ERA behind the passive armor was there and is still there. I don't know what type of ERA that is, what materials they use, what backing and the details. I just know there's ERA at the back.

     

    The change in armor (which occurred in 2007-2008) in the Merkava 4B, was to the NxRA. The passive armor itself, regardless of the ERA, was changed so that hits would no longer remove parts of the armor, and keep the passive armor more intact.

  5. This is the image were it says "Explosive" right?

     

    So, does this mean the side armor of the Merkava 4 is ERA.

    Or maybe NxRA?

    I know NxRA stands for Non Explosive (X) Reactive Armor. But in NxRA there is a reactive material between in plates right?  Could this material be considered explosive?  Though, not powerful enough to explode the module like in ERA.

    Xoon.

     

    1)That's the image indeed.

    2)It does mean the turret side armor of the Merkava contains SOME ERA, not entirely though. 

    If you look at this image:

    You can see the composition of the armor as the coverplate was blown off, in the Mark 4A.

     

    It's highly likely that Mark 2D, 3D, 4A and 4B all have underlaid ERA, as these are based on a similar principle.

     

    The basic armor is NxRA in its nature on all these models, and the recent improvement (2007) was to eliminate the exposure issue seen in the image above. What is also seen in the picture is that the armor reacts violently upon hit, even without the use of any explosive material. 

     

    What I guess is that only a single or less likely few explosive layers exist within the armor, at the very back of it, acting as a last line of defense. 

    This would not have however the disadvantage of hard maintenance as seen on multi-ERA based armor of the Oplot-M, as by the time the ERA is initiated in the Merkava's side armor, the whole armor module would have been pierced and compromised, requiring full replacement.

     

    3)Bottom line; the armor itself is NxRA, but is not related to the ERA located behind it.

  6. Zuk doesn't post here so I will copy a post of his from the AW forum.

     

    That is, indeed, not a panoramic sight (me thinks). As you can see it's not placed where the panoramic sight is usually located. The actual sight is located further in the back and is either closed or rotated to the back. 

    Just a bit in front of the commander's hatch before the roof armor.

    Zuk also posted to his thread the following (taken from the video):

  7. Because it's highly improbable that Rafael just chose to copy whatever design a few Soviet engineers brought with them, if they even did. And they would not seek other foreign help if they would already have a ready design. Keep in mind the earliest ERA was a very simple design.

     

    What IS probable, in my opinion, is that key figures in Rafael heard about the concept itself, of explosive armor, and chose to design one themselves (again, with foreign help).
