The spec you provided say otherwise, Its L48 gun with just Chamber pressure of 575.5MPA cannot be as par as KBA3 or Older guns not even 2A46M..
Ha ha, and were such figures as 1000mm, your fantasy ??
I know that You have problems to read with understanding. I wrote "So while for NATO tanks penetrators lenght slowly comes close to approx ~1,000mm," approx means approximetly, close to, not nececary 1,000mm, it can be 950mm and then it is close to.
There is no physical possibility to place in this autoloader round of the same lenght as DM53. I know Your silly pseudo patriotism will not allow You to admitt this. And it was discussed many times.
Calliber have nothing to do here, neither lenght. Americans were capable to develop ammunition that greatly increased capabilities of L44 gun. So not gun is the key but ammunition.
With advancement of ammo and longer Guns and Rods..
It is not problem of a gun, or ammunition itself, but just space inside a tank.
There are no current penetrators with such figure, M829A3 is no more than (maximum) 800mm, so where is point of that statement, comparison of inexisting rounds to what there is today ??
Because there is no necessity ?? Autoloader is designed to handle two-piece ammunition, you understand difference between that and unitary rounds ?
If you have gun with higher potential, caliber, lenght, sooner or later it will reach higher performance, that is being reflected now with modern ammunition.
Ha ha, what ??
Western 120mm rounds are unitary, reach 1000mm projectile lenght, 125mm are two-piece ammunition. You are comparing two very different things.It is not problem of a gun, or ammunition itself, but just space inside a tank.
In western tanks, there is enough space in ammo racks to place there longer rods, M829A3 have allready impressive lenght.
It is possible to place there even longer round, M829A3 as a whole round is close to 1,000m in lenght.
It is however immposible to place such ammunition inside T-xx series, simply because there is not space inside for such long ammunition.
We with you talked at the beginning about rounds "Cobra". They had length 980 мм.It is not problem of a gun, or ammunition itself, but just space inside a tank.
In western tanks, there is enough space in ammo racks to place there longer rods, M829A3 have allready impressive lenght.

Rather form here:
I shown it for you - the limitation is here:
We are talking about penetrator lenght (important thing) not projectile lenght. 1000mm is irrelevant, it is unitary round.
Current 125mm ammunition Svinets is about the same as DM-53 which is latest round, so how it is limited in performance ?
The penetrator lenght in M829A3 is ~940mm : balistic cap +rod + fins. The most important part: rod is 780-800mm long.
Not 1600 but 1555m/s. It's first. Second it basic physicist - even slower object but with bigger mass (heavy and thick rod in M829A3) will be have biger MJ energy. And in M829A3 is composite sabot with wery low weight -so almoust whole energy from this 12,1MJ is transfered in to penetrator. Please come back to my post about polish modernization 125mm APFSDS with composite sabot...
Have you posibility to put in Lead-1/2 longer then 740mm penetrator? No. Have you posibility to put in to DM63 longer then now penetrator? Yes.
That is what we were talking about. Rest is not relevant.
If pressure created by M829A3 is about same as DM-63 from L/44, projectile (not necessarily rod) will have same energy.
Possibility, there is also possibility, 2A82 gun will soon be adopted :cool2: but now Svinets is same as DM-53 so there is no argument.
I would not state any figures on this moment, because there is no knowledge. Only thing we can assure, is that it is no worse.
It was about posibilities about placed the longer penetrator then now in estern 125mm APFSDS.
Of course not. The most important is MJ only for penetrator during fly. Rest is not so important. In fact this 12,1MJ for M829A3 due lighter composite sabot and longer and heavier penetator can give more MJ during fly then even L-55 and 13,5MJ for DM-53.
And lighter sabot, and other factors... its not so simple.
Energy durig fly is not the same.
in theory yes -13,5MJ vs 12,1MJ. But this whole "MJ" are for penetrator and sabot on muzzle. And it's not relevant becouse for exampe 13,5MJ for Dm53 L-55 can have only 9-10MJ during fly for penetrator only, and slower but weight more and having ultralight composite sabot M829A3 can have for example 10-11MJ during fly. Of course it's only example. But as I said: the most important factor is MJ value for penetrator during fly and transfered into target. MJ for muzzle and sabot+penetrator is not relevant. The same muzzle velocity or MPa pressure
Sorry but it's not so simple. In T-72/90 hull there is no possibility to have longer then 740/750mm long penetrator. There is no way whit this autoloader! It's impossible.
Apart that what Виктора Ивановича had said: "40% better then Mango " which give us: «Свинец-1» 644mm -700mm RHA for 2000m
Now it is the same. In future will appear new gun 2A82.
Yes, perforation will depend on energy of rod, but it is not that simple, there are other factors, diameter, velocity, etc.
Yes, I said what will define perforation is energy of rod on my earlier post.in theory yes -13,5MJ vs 12,1MJ. But this whole "MJ" are for penetrator and sabot on muzzle. And it's not relevant becouse for exampe 13,5MJ for Dm53 L-55 can have only 9-10MJ during fly for penetrator only, and slower but weight more and having ultralight composite sabot M829A3 can have for example 10-11MJ during fly. Of course it's only example. But as I said: the most important factor is MJ value for penetrator during fly and transfered into target. MJ for muzzle and sabot+penetrator is not relevant. The same muzzle velocity or MPa pressure
I know, I talked about that on my post about M829A3. But theoretical perforation (on RHA) and energy, I do not see any reason why M829A3 should be better.
In T-90 there is possibility to adopt 2A82 gun, and it will be fielded in Armata. Such gun is on another league... so this comparison is no longer valid.
He is journalist, it was statement from representative.
OMG... Kunal, I had wrote about CL3254 many many times here...It's the same round known as polish PRONIT.
Bullshit. No more then 540mm for 0. for 2000m.
