Tank Guns and Ammunition

[313230]

Does anyone have the chamber diameter of tank gun and artillery cannon 120/125/155mm? It seems slightly larger than gun diameter but I can't find info about it.

Государственные испытания танка "Армата" не за горами

Так, бронепробиваемость зарубежных тандемных БЧ ПТУР AGM-114L «Хеллфайр», «Бримстоун» и других составляет 1200 мм, а бронепробиваемость БПС DM43 (материал сердечника – из фольфрамового сплава) равна 350 мм/60 град.

А вот с аналогами зарубежных БПС дела обстоят совсем плохо. Для оценки бронестойкости нового танка БПС 3БМ42 (бронепробиваемость – 220 мм/60 град.) и 3БМ48 (300 мм/60 град.)

WTF?
DM43 ~700mm for 90. plate?
3BM48 600mm for 90. plate?

I don't really see much reason for "WTF". As I mentioned several times mathematically DM43 is better than M829A1 (often attributed with 650 mm penetration at 2,000 m). If we also include the improved performance against sloped targets (which is something which was specifically mentioned on DM43 product page), then we have only ~650 mm for 90°. If we than take certified penetration instead of average it could end up as low as 600 mm penetration.

Global Tender for India's T-90 Tank Ammunition


The Indian Army is entering the global market for the purchase of unspecified number of ammunition worth $550 million for the Russian made T-90 tanks it operates. The ammunition being used by the Indian Army for the T-90 tanks was contracted along with the purchase of T-90 tanks in 2000.

While the Indian made ammunition for the T-90 tank has been rejected by the Indian Army due to technical faults, the price of the Russian made ammunition has been increased 300 per cent by the Russians.

The Indian Army has now decided to hunt in the international market for a variety of ammunition for the T-90 tanks, including the standard 330 grade ammunition and two other varieties for the T-90 tanks.

The tender is expected to be floated in December and is likely to be sent to

Dhiel defence of Germany,

IWI of Israel,

Rosoboronoexport of Russia,

BAE of United Kingdom,

Bumar of Poland and

Ukrainexport of Ukraine.

There were technical problems with the Indian made ammunition for the 125 mm gun of the T-90 tanks especially relating to packing and the rate of the fire. As such the Indian made ammunition has not been used for years, and is lying unused. The Indian Army has rejected the Indian made ammunition and has been using the Russian made ammunition only contracted along with the first contract of the Tank. The Russians want 300 per cent increase in price of the ammunition for extra supplies.

The purchase of the ammunition for the T-90 tanks is likely to be done on Urgent basis which would mean that the winners would be selected in the shortest possible time.

I wrote already, that to not official information about the Ukrainian shots, it is necessary to collect scraps.There are new types of shells in Ukraine,(BM44U and BM44U1) Also there is the experienced shell ( he does not have the official name while) at a speed of a 1820 m/s. But on an export is supplied mainly BM44 (3BM42) -1700m/s. To the armies of customer of seizes and similar shells. And AL the Ural tanks has limitation in long. And in foreign armies mainly Т- 72 and Т- 90.

 

[Kunal Biswas]

So in that sense we may receive 3BM-42 Mango from Ukraine on cheaper Price..

Thnx.

For this purpose and there is a tender. Here question, why is he needed? India produces 125-мм rounds.

 

[Kunal Biswas]

Yes, India does..

But due to faulty manufacturing of charge bags these are rejected..

Also in Army side, These new generation ammo are used on older Guns which also cause a blast in barrel..

Polish 125mm APFSDS is good option:

1. It's developed and tested.
2. Have hight quality (after fail whit imported rods from Israeli)
3. Have guite good performance (520mm RHA for 2000m) - better then standard 3BM42.

I will consent. Polish "Pronit" better what 3BM42 But all depends not only on parameters and price, but yet from the decision of officials.

Militarysta do not talk about "Pronit" APFSDS, as it is not manufactured anymore, and not much were manufactured, but WITU was working on completely new APFSDS ammunition, there were also rumors about cooperation with Germans in this subject.

And I talked not about experience, and about serial ammunitions.

The Swiss shells were unitary, because they used standard Leopard2А4, only done under a 140-mm gun. Uses unitary shells yet Leclerc, but there is autoloading. In case with М1 or Leopard 2, it is necessary to develop the mechanism of before loading, not to lose rapidity of fire. Exactly this factor restrains anymore, than the fluctuations of the barrel.

No, they had two piece ammunition, but both pieces were shorter than "NATO" (quadliteral) 140 mm ammo.

Leclerc with 140 mm tank gun would use the same ammo as Germany or U.S., because the UK, the U.S., Germany and France agreed to develop their 140 mm systems with a common standard.
