This storage is Ukrainian designed for 125 mm rounds

So we have confirmation that Ukraine actively participated in Al-Zarrar and Al-Khalid programs

there was one source if i correctly remember which mentioned that al zarrar upgrade will bring it closer to t-80ud as per ukrainians.

beside this there are rumours of pak upgrading the t-80ud as well

ukraine participation in Al khalid

*Helped pakistan in local manufacturing of 125mm smoothbore
*Helped in armour tech
^in ERA as well
*varta APS
*kombat atgm(with even bigger warhead(source defencetalk)

Seems like Azerbaijan has recently purchased 200 T-90S

Nothing to do with ERA and armor, the main participation in Al khalid is powerpack.

Thanks Mr.Harkonnen.

By the way, most of the Pakistani forums claim that their new ERA Aorak is an "upgraded" Duplet. Did any ToT take place?

If we can see disassembled ERA cassette, we can say if AORAK works like "Knife/Duplet" or like classic ERA.

They are wrong. Pakistan does not aquired Duplet or any of it's modifications for now.

There was a pic of Pakistani ERA -

but it was not deployed, A-Khalid uses chienise 1-st generation ERA.
Any pic of AORAK ?

Andrei, in Nozh ERA, are all linear shaped charges in a box denote at the same time of striking or each SC denotes separately by its own fuze?

linear shaped charges action 1 after another providing continious effect against atacking projectile.

They claim this is "Aorak" MK-1 and say Mk-2 is "Duplet" modification. I didn't get pictures of "Aorak MK-2" by requesting on def.pk (avoiding the question and not providing pictures other than the one you have posted)

Also, they claim that the below pictures show "Aorak". It doesn't seem to be anything like Duplet or Nozh, not in the least.

2A46 (T-72) has a proof pressure of 8000 bars. Autofrettage pressure has not been mentioned anywhere. Proof pressure for the gun has been increased from 6700 bars to 8000 bars. Max chamber pressure is 6500 bars for the 2A46 as of today up from the earlier 5500 bars. This is official information. Came straight from OFB. EFC has been increased from 250 to 1700.

Max chamber pressure for ARDE gun is 6120 bars and proof pressure 8000 bars. Came from ARDE and is official. EFC is 500. However this info is true as of early part of this century. Not sure if the gun has seen any upgrades recently for Arjun Mk2.

2A46M-2/5 is supposed to be 8000-8500 bars and max chamber pressure of 6500 bars. EFC is 1200-1500(?). Of course, this bit is not officially verified and comes from internet sources like fofanov unlike the other two.

@Keshav Murali, the ERA on Al Khalid is not "Knife", neither "Duplet" IMHO, but a Chinese ERA.

That was what I was trying to tell them but they started going patriotic and well, logic doesn't work there.

No, proof pressure is 612 MPa. The gun has "partially autofrettaged to a pressure of 800 MPa.
It's all written there.

2A46 (T-72) has a proof pressure of 8000 bars. Autofrettage pressure has not been mentioned anywhere. Proof pressure for the gun has been increased from 6700 bars to 8000 bars.

That's not realistic. First of all the 2A46 tank gun has no proof pressure of 670 MPa... so I think "proof pressure" is not the right term for what they want to describe.

EFC has been increased from 250 to 1700.

They seem to rather have changed the definition of EFC. If they use the value 250 EFC for the 2A46, then they refer to APFSDS (which equals to 3 - 5 HE-FS or HEAT-FS), else they are contradicting with the Russian and German sources available about the 2A46 tank gun.
For 1,700 EFC the definition had to be changed so that EFC equals HE-FS/HEAT-FS

2A46M-2/5 is supposed to be 8000-8500 bars and max chamber pressure of 6500 bars. EFC is 1200-1500(?). Of course, this bit is not officially verified and comes from internet sources like fofanov unlike the other two.

There is no source claiming the 2A46M-5 has a proof pressure of 800+ MPa. That the barrel life was increased has officially be stated in the T-90MS flyers.
