Arjun Main Battle Tank (MBT) Mark II

[Archer]

thermobaric round is a fancy term, its more of a HEAT round, used to eliminate fortified bunkers, buildings etc. No big deal

There is a difference between a thermobaric round and a HEAT round. If the developer says thermobaric, its wise to take them at their word and explore what that means.

And who told you that they didn't simply reverse-engineer Kontakt-5? The snipplet about Indian ERA posted on the previous place says that it is "having equivalent performance". So it does not actually matter if it is a Kontakt-5 clone or not (even though the odds of getting the exact same performance with a different working mechanism are extremly minuscule). It's seems to be very likely a case of India not having made a ToT contract for Kontakt-5 and hence being forced to copy K-5 in order to keep up with the requirements for armour protection.

Two contradicting terms--

Here's something more to ponder about-- K-5 is already made under license-- for which money is paid to Russia under contract-- outright copying of a Russian copyright material under different name and not paying them would be violation of T-90S contract which forms the bulk and top tier of armor core-

Hence by a layman's term using the very same K-5 would be better option-- off course Russians would be more than willing to provide the best they got if pay is good in case of India here-

He knows more than the Developer No big deal-

5. work on "new" indian 125mm APFSDS round whit penetration level circa 600mm - like on latest IMI rounds offered to India -yes? future Mk.III yes? it shoud be redy when?

You should have watched the interview of Dr Avinash Chander he is the DRDO boss and had something to say on new APFSDS being tested currently- It was posted few pages back-

About the when part-- the new round would be known perhaps when Mk2 Arjun- is inducted in services-

125mm APFSDS next version would announced once T-90S upgrade package is announced after new orders of improved T-90MS is placed--which is likely to happen-

Thank You for this very valuable post! It explain my a lot about IA ammo and indian industry ammo.
It's very interesting that first IMI round for India (penetrator) have problem - like slighty previous polish PRONIT has. The same scenario what is interesting. More then 20% PRONIT 125mm penetrators for Poland (taken from IMI) had serious falitures and don't achive needed by army level 540mm RHA at 2000m. In reality it was under 500mm. It was more then decade ago.

to claryfied, so we had in 125mm APFSDS in India:

1. DRDO "first and faliture" APFSDS -this whit mixed DRDO penetrators with imported Russian propellant - program dropped, yes?
Any details about penetration level of this dropped round? Mk.I yes? It was redy when?
next:
2. IMI licenced APFSDS whit imported penetrator CL3254M -so propably polish PRONIT analogue. And in the same way those round have serious falitures... Mk.II yes? redy in 2010- yes?
menhwile:
3. old 3BM42 Mango from Russia whit T-90
after that:
4. imported 66 000 overpriced 3BM42 Mango from Russia
+
5. work on "new" indian 125mm APFSDS round whit penetration level circa 600mm - like on latest IMI rounds offered to India -yes? future Mk.III yes? it shoud be redy when?

Militarysta, its 5 am here and am off to bed being an old coot and all. Longer nights mean bigger headaches. Will reply to you tomorrow.

Edit: Sorry about the wrong name.. mixed up posts.

He knows more than the Developer No big deal-

there is something called common sense, but you seem to take everything on face value.

Thermobaric rounds are designed on pattern of High Explosive warheads, they are meant to destroy bunkers, fortifications, buildings, in some cases against steel etc.

But they are NOT meant to penetrate a composite layered armour. RPG-7 and other HEAT rockets have thermobaric warheads


for a generl reference..

Thermobaric Weapons




Google it

 

[Archer]

And who said its meant to penetrate composite layered armor?

Don Quixote tilting at windmills indeed.

Militarysta, in fact need to dig out a few of my old notes that might clarify the issue even more.. so tomorrow it will have to be.. sorry about mixing up your name..Cheers

Where did the developer-- or myself or any one for that matter said anything about what that round is supposed to do-



Trivial-

What kind of warhead is used in an armor busting missile ?

go through last pages.. Gosh !

I did before quoting your nonsense-

Did you find an answer to the trivial I gave you ?

Let us get back to posting informative posts again. Please avoid one-liners.

Originally posted by @Kunal Biswas, I am reposting them here to give a better view of the right-front edge off the turret armour of Arjun Mark II. It is unclear what kind of additional armour that is.

And here are two images of the side turret protection, and apparently, it is not some storage box, as earlier speculated, but real armour.

It's a target acquisition system for Arjun missile's. Like LAHAT and DRDO CLGM.

Sure,
thanks for claryfied thinks about indian ammo and tank program anyway. It's really interesting for polish point of view - especialy problem with the IMI and quality of they rounds...

btw: Have I notice that Poland in 2001 bought licensed production for Spike ATGM - 264 lunchers and 2675 missailes, and first batch imported form Isreli had 14,5% falitures ATGMS (fell down after lunched). The problem was in software in cold, foggy, rainy weather. Now produced in ZM MESKO factory "polonizated" Spkie ATGM have only 1,4% falitures. The same israeli IFV turrets: RCWS-30 and UTD-30 where rejected after tests in polish climate couse both turrets don't fulfilled more then 60% requirements of the polish MoD -for example in temperature -20 C degree both turrets where unable to fight... German and italian turrets havn't sucht problems in Poland. The sam old ex-Soviet of course

Thermobaric means the warhead would have a air-fuel mixture which would create immense heat and pressure when exploding. Specially effective for bunker busting and cave busting. This is more of a anti-structure/anti-personnel round and definitely different from HEAT.

 

[shuvo@y2k10]

what is the difference between thermobaric and hesh round? i suppose both are use to set up a pressure wave against concrete structure.
