Arjun-II MBT development l Updates & discussion.

Nice tank indeed

Then what exclusive club are they talking about here?

It may be noted that only four gun systems in this performance class have been developed abroad namely in UK, Federal Republic of Germany, France and Russia. Even the US and Japan have opted to adopt and licence produce the German 120mm Rheinmetall gun.

That is in reference to:
UK developed the Royal Ordnance 120mm L30 rifled gun for Challenge 2 and L11A5 before.
Germany developed the Rheinmetall 120mm L44 smoothbore gun (licenced to US, Japan) for Leopard 2
France developed the GIAT 120 mm GIAT G1 smoothbore gun (L/52) for AMX-40 and CN120-26/52 L52 smoothbore for LeClerc
Russia developed the 125mm 2A75 and 2A46 (D-81T) L48 smoothbore cannons

But there are also:
Italy's Oto Breda developed a 120mm L44 smoothbore, which apparently is not a Rheinmetal copy (but who knows).
Israel developed a IMI 120mm L44 smoothbore gun, which supposedly is not a Rheinmetal copy (but who knows).
Ruag of Switzerland developed the 120mm Compact Tank Gun smoothbore.
Ukraine 125mm KBA3, 125 mm KBM1M / 120 mm KBM2 tank guns
Still it is a small group, to which India can be added for developing its own 120mm rifled gun.

@Penguin There is lot of confusion regarding the penetration power of DRDO T-1 FSAPDS round.

On one it says penetration 300 RHA @ 2000m, while other says its capable of defeating triple heavy standard NATO target @ 5000m. What is the relation between RHA and Triple heavy NATO target and how does this fair when compared to other 120mm FSAPDS?

 

[Penguin]

The purpose of the triple heavy target is to represent the difficulty a projectile would face in penetrating the skirt, roadwheel, and hull of a Soviet tank.

NATO targets - Wikipedia, the free encyclopedia

Triple Heavy Target - First layer is a 10mm plate (412-438 kp/mm² hardness) at 60 degrees, followed by a 330mm air gap, followed by a 25mm plate (100-122 kp/mm² hardness), followed by another 330mm air gap, and then an 80mm plate of 308-353 kp/mm² hardness.

This target represents a notional Soviet heavy tank impacted on the side skirt at 30 degree angle off axis, so that the round needs to penetrate the side skirt, the wheel, and then side hull. This test is intended for testing HEAT rounds, hence all the spacing. The triple target is harder for HEAT than KE due top all those airgaps. In terms of date of introduction, this is a very old target that goes back to the days before reactive, ceramic and composite armor.

Does it mean that T72's ammo have more penetration than this T-1?
View attachment 125910
What does the highlighted part mean? Isn't it related to penetration.

as of now, t72 uses bm-42 mango penetrator with average penetration of 440-460mm armour at 2000 meter so technically yes it penetrates more armour than Arjun's apfsds.
The highlighted part represents a typical nato style ttipple hardness, thiugh obsolete in todays terms, shell that penetrates 300mm armour @ 2000m will penetrate even less at 2500m, 3000m if it reached that far. You see, there aremany factors involved, velocity, length diameter ratio etc. The reason why 2000m is usually given is because it is a safe engagement range where a penetrator often performs at optimum level, going farther, percormance reduces.

How can they test it against BS?

I don't dispute that if it's good enough against Milan & TOW, then BS is not an issue, but how did they test it against it?

I'm also assuming they bought a few test rounds of TOW from US?

The IA has rounds of the BS also......
As well as complete launcher-sets of Stingers and Anzas............. Remember Kargil?

prove it or it never happened. as far as BS is concerned, there exists many variants with single/tandem warheads are wire/ mmw guidance. No stinger was used in kargil, anza was enough for migs.

now if you want to rant further, open a new thread or stay on topic.

How many anti-tank/anti-aircraft missiles were destroyed during the 1988 Ojri camp disaster?

Actually I remember reading a Pakistani news article saying the other way round. That was why IAF was capable of carrying out so many raids. That was also the reason for upgraded version of anza post kargil.

open another thread on kargil story, the thread is on arjun mbt. In brief, your post is factually incorrect.
