intresting artical on T-99s gun

高膛压火炮实际都存在炮膛烧蚀严重的问题,只是程度不同。我国的坦克炮的巨大威力决定了它的烧蚀问题很严重 ,说句不好听的,有点拿寿命换威力的意思。其实这也是没有办法的事情。我国的125实际发展了三代,目前装 在99上的是第三代,其威力足以把这个星球上已经出现的和正在已知研制的坦克彻底打回老家,所以,我国并不 急于把更大口径的家伙拿出来,但不是说没有。只是怕被人扣上“大规模杀伤性武器â€的帽子。呵呵 。
In fact ,high-pressure cannon can’t avoid the serious ablation of its core completely,more or less. The terrible power of our (meaning Chinese) cannon is destined to cause a serious problem of ablation.frankly speaking, just enhance the power of cannon at expense of its lifespan. After all ,no other choice is available. We have developed three generations of 125 MM cannon and that fixed on ZTZ99 is the third one, the power of which can blow all kinds of tankers existing or under development on the earth into pieces. So, we(Chinese engineers) have no anxiety to show up more powerful cannon with bigger cailiber ,which we have grasped long ago. we do so just to avoid the accusation of “WMDâ€

以下纯粹是鄙人信口开河,大家随便看看了事。
The following is just my blow, don’t be too serious about it.


我国当年得到125样炮,也就是出口型2A46后的情况,我们当时想当然的认为2A46的威力比我们在研的 120大,心存敬畏,没办法,被老毛子的装甲力量吓怕了。结果炮一响,眼镜掉了一地,这个东西根本就不是想 象的那样。一分析,2A46的内外弹道性能都有问题,而且很多东西不是用出口型可以解释的。再加上性能低劣 的出口型弹药,威力低是肯定的。这一炮打掉了中国人的畏惧。我国在2A46的基础上,对身管进行了一定的改 进,威力就有不小的提高。这就是第一代125,但是没有装备部队。随后的进一步改进型号(其实这个时候的炮 和2A46已经差别很大了),装备了部队,就是96上的炮。第三代就不说了,99的重锤就是它。这个时候的 125已经和2A46没有什么关系了,其威力打T80个对穿都可以
when we(Chinese engineers) got the first 125MM cannon ,Russian model 2A46 for exportion , we certainly took it granted that it surely had more power than the 120MM cannon we wer developing because all were awe of Russian bear, frankly speaking ,frightened by its armor force. But when we fired the Russian cannon in its power-test, all were surprisedat its poor performce that was completely unexpected. After analysis, we (Chinese engineers) found that its poor performce cound’t be simplely artrubited to the fact that it was just a model for exportion, because there were some wrongs on its ballistic trajectory. In addition of inferior ammunition for exportion, Russian 2A46 cannon is really a gabage. So, the poor shot of Russian cannon in the test drove up all Chinese fear. On the basis of Russian 2A46 cannon, we made some betterment and mend on its “pipe†and improved its power by a considerable margin . That is the first generation of our 125 MM cannon for tanker but it has never been equipped with our troop. The following upgraded 125 MM cannon (which is quiet different from Russian one) enters into service and fixed on T96 MBT. The third generation of our 125MM cannon is the "big hammer" of ZTZ99 MBT, which has nothing to do with Russian 2A46 cannon and can easily break a hole through Russian T80 MBT from the face to the ass.

wow...a 2a46 can mission kill out an m1 from the side or rear. the article didnt even mention its bastion abilities. so if this chinese gun is an improved 2a46, it must pack a big punch. i wonder why the russians never thoguht of improving the 2a46...i mean its not really so hard to lenghten the barrel.

Mig re-read the last part.

can easily break a hole through Russian T80 MBT from the face to the ass.

now weather it can do that to a M1 is a different matter the T80 and M1 are different structures, also factor in sighting systems reload time and a number of other factors and of course the ultimate factor Reality and theory and it all come down to chance.;

i read through and clear. i was saying from other study that a 2a46 on a iraqi t-72 had once blown up the turret of a m1.

A BMP's 30 MM can mission kill a M1 from the side to the rear. As with all tanks the M1 is reletively unprotected from the rear, side, and top. Higher calibre does not mean more power. The 120MM easily outguns the Russian 125MM. An m1s turret has never been "blown up" (my understanding of blown up would be seperated from the hull). the only way an Iraqi can be done is a hit from the air where the m1 is most vulnerable. The reason the t-72 turret "blows up" is because of the autoloader and the munitions from inside the tank. The M1 was designed for a head to head tank confrontation where its tungsten, chobam, and DU armor lies.

the M1 separates it's ammo from the crew so unless you hit him just when the loader had his belly on the door button your not going to get an M1's turret to blow up like that. knocked out yes Blown up no.

everyone knows a 120 is more powerful than a 125.i dont know where u got the idea that i thoght the 125 was more powerful. its the atgm ability that gives a 125 the advantage. my interpretation of blow up means the turret was hit and an explosion occured. no seperation.

Russian 2A46 lives about 700 shots, while it's export versions have lifespan of 200 shots. If to assume that chinese modern gun is a second upgrade of export version, then how many shots will it live, if it's lifespan was reduced even further :confused: ? Anyway this article's language doesn't seem much professional, can we even trust it?

the M1 separates it's ammo from the crew so unless you hit him just when the loader had his belly on the door button your not going to get an M1's turret to blow up like that. knocked out yes Blown up no.
For some reason M1 ammo doesn't blow up in a common manner. I've seen several videos, showing ammo burning with a high speed, like fireworks, undoubtably causing high temperatures, and i believe crew members have a fat chance to die in this case.

In fact 125 is more powerfull. It is due to autoloader's structure russian-style guns can't use long APFSDS rounds. Comparing 120 to 125 rounds of similar length/subcaliber ratio 125 is always better. And to say frankly most russian ammunition doesn't even use all potential of it's ratio. Anyway most similar discussions do not make much sense, for gun's effectiveness depends much more on the shell, then on gun itself.

The only interesting part of this article is that it states that the Chinese gun in Type 98/99 is not based on the 120mm chinese gun, but as I and few others have said all along, it's offspring of the russian gun. Those claims that it would been far more superior to the orginal 2M46 are just nationalistic poasting and the designers high belives on their own product. To determ which gun is better, we have to wait more spesific and trustable data...

Chinese gun uses DU APFSDS shells, so this alone is an advantage of a sort.
By the way, russians did make attempts to improve 2A46. Original concept of T-90 (obiekt 187) had improved 2A66 maingun. Late T-90 was switched to obiekt 188 due to insufficient founds.
