hmmm... well Key you may have a point there. Now I am going to be spending time trying to research the "flat surface" issue..
JDW has a an article that talks about persisting problems with Arjun leading to India looking for increased foreign participation to allow for the program to be salvaged.
*India's Arjun MBT remains on the starting block
An Indian parliamentary committee has urged the Defence Research and Development Organisation (DRDO) to seek foreign assistance to overcome continuing problems with the Arjun main...

Wonder what the rest of the text says? Can anyone post it?
I have discovered the answer to the above question.......Appparently it's ceramic armour that requires it to be "slab" sided. Ceramics cannot be sloped as it exposes more of the tiles to damage when sloped. Hence the flat surface.
SO ugly! look at 99G form china:
If you are going to troll, at least learn to spell correctly..
ceramic armors require that they (indivual tiles) be sandwiched in layers and seperated. ussaly a shock absorbing front to protect the tiles from non-penetratig impacts a simple resin or poly compound can do this. But rigedly encased in steel or titanium on the sides and rear to provide rigidity to resist penetrating impacts. becuase impacts damage the tiles, ballistic sloping potentially exposes more tiles to impace as the enemy round deflects and travels across the face of the armor instead of expending all its energy in one location. Slab siding reduces this and lets a smaller segment of armor bear the full brunt of the attack without weakening the rest of the protection package.
When seen from this PoV the Arjun is beutifully laid out with almost no angles caapble of compromising the armor package. Although putting the site in the center of mass is begging for mission kills as the optics gets taken out.
The Arjun uses Kachan (Gold) and it is rummored to be world class. I have no doubt that due to delays in the rest of the Arjun program the armor has been continually updated to meet new threat levels.
I have to agree with the fact that Chinese tank looks perfect and Indian tank looks like old Tiger tank from WW2... The 90 degree slope must be a wrong design. Even basic tank ideas are opposing 90 degree angle. Somehow the Indians must have skipped that lesson just like the fact that it is heavy armoured while it needs speed, the fact that it is heavy while it has to cross small bridges, the fact that it is still mainly imported, the fact that it does not suit hot area's while it will be used there etc etc etc
Don't mind the spelling. The fact that the person doesn't like the design is not very difficult to understand.

Zraver the location of optics of due to carryout over of faults owing to similarity with Leo's and German consultancy in the design. I hope some one realizes the need for change before it is too late.
Also it is interesting to know that the armor material also dictate the design of the turret shape. According to your opinion how would the flat faced design fare with respect to kinetic rounds/misiles?

It depends on what the Kachan in the production models is being formulated to resist. One thing India does not lack is brain power, IIT makes sure of that. They have the capability to design a ceramic every bit the equal of the new Chobham II. If it is designed to ressist KE over CE then CE will suffer and vice versa. Since I don't have acess to classified info on the armor I can't say for sure. But do remember India has acess to the 2A46M-5 L/52 with (presumably) the BM-42M or BM-48 mid leangth penetrators which should in theroy equal or exceed Pakistan's DU round. If Pakistan relies on KE penetrators to kill tanks (and they do) then I would surmise that KE protection is high.
One a side note, expect the Arjun to under go a Leo 2A6 type transformation with ERA on the top now that PA is getting TOW C's.
Munir,
can I call you stupid? I mean thats what you are so its just being honest.
The basics in armor design are to posistion your armor in such a way as to maximize its protective value. With Ceramics this means slab sides (I am assuming the Chally 2 has applique or spacing behind the angles and ahead of the ceramic for obvious reasons)
Ballistic shaping relies on deflecting the enemy shot and by increasing the thickness of the armor via the aspect of the armor presentated to the enemy fire. This was a good idea in WW2. In 1992 the world saw just how useless ballistic shaping was to modern APFSDS rounds.
The Russians, Ukrainian, and Chinese and others who use tanks with Ballistic Shaping have completely discarded the value of the steel. The Russians use heavy ERA, the Ukrainian's use Vozh composites, and the Chinese use ceramic facings.
Regards the shaped armour issue.....If it is no longer in vogue why has the Leo A6 got shaped frontal armour? Those additional panels are hollow. I have seen the panels off the tank.
