Reloaded Arjun Killed At Birth?


Livefist: Reloaded Arjun Killed At Birth?

Another bunch of horsesh!t from Aroor. He can justifiably claim to be amongst the worst defence journalists India has produced. The MK2 is still in trials and the Army has not anywhere decided on how many it will require. At this juncture to come out with an article full of regurgitated rubbish and hyperbole, plus some masala like Aroor does, is just irresponsible journalism and clearly just desparation to drive eyeballs to his otherwise staid blog. In the past, he has taken PPTs released by agencies at public events, put his name on them, and then passed them off as scoops. He has written hatchet job articles on various organizations. He neither understands technology nor does he have the integrity to desist from finger pointing. All said and done, such media people are really the reason why the Indian public remains underinformed about defence affairs.

i think this is a planted story.first of all the arjun mk2 mbt picture does not look real.as per reports it is to feature a sloped frontal turret and the tank should look like leo2a6.

It is the picture of Arjun MK2 for now, Col Shukla posted the same photo some time back..

We are yet to see the real image of it..




T-90S is out of equation here in Arjun thread..

 

[shuvo@y2k10]

the arjun mk2 is undergoing trail since may 2011.first prototype had 39 improvements and now second prototype which is stated to all 93 improvements will undergo trial from june 2012.the article written by shiv aroor is bullshit.

This is one and only available video of Arjun MK-II. ERA is not put on this but it will be it is just add on.

 

[Kunal Biswas]

I assume this is prototype one with first prototype..

We have to wait little longer to see prototype 2..

 

[Kunal Biswas]

 

[sayareakd]

we should make it like this

with respect to ERA. and the gunner sight should be made periscopic sight.

 

[Kunal Biswas]

we should make it like this

with respect to ERA. and the gunner sight should be made telescopic sight.

If not that all..

Than at least like these with ERA tiles giving a extra layer of protection..

singapore leopard 2sg..

Giving the fact, Arjun and Leo A4 share alot of similar deign..



Arjun is going to be 60+ tons anyway..

Kunal sir is that BFSR in red square and those are 360 degree warning receiver for anti tank weapons in red circle, just like trophy system?

That is true, It can be also some sensor for hardkill system..

Though if that is BFSR, Its a terrible place to keep it..

Sir, that is good place to put it, if we can make it rugged, plus with BFSR, arjun tank get very long (sensor) eyes

As per wiki BEL BFSR has following range

Crawling Man - 500 m
Walking man - 2 km (1.2 mi)
Group of people - 5 km (3.1 mi)
Light vehicles - 8 km (5.0 mi)
Heavy vehicles - 10 km (6.2 mi)

So if the main gun is collaborated with BFSR then it can hit target at even large range.

Gun is placed at good location because BFSR needs gyo stable platform, which the gun already has, hope one is sufficient, two would be good on either side.

 

[sayareakd]

Gunner sight should be periscope sight with ERA cover would take care of weak spots on armor. Just image it like this with ERA cover.

I think they have done this here

 

[sayareakd]

Kunal sir with respect to BFSR

here is something i found, posted earlier.

this is the real pic from the video

 

[sayareakd]

Kunal sir you are right from the looks of this pic

radar should be in line of tank's gun. It should be on the right side.

It would not have much effect. A low-velocity full-caliber round (HESH) will have a very high dispersion at longer ranges and need a very high angle of gun elevation. The Indian APFSDS for the rifled gun will have to low performance to sufficently deal with tanks at long ranges. Realistic is that HESH will be effective out to 4,000 - 5,000 m against tank sized targets max. (a range which should be achievable with normal gunner's or commander's sights, while the APFSDS should be used at ranges below 4,000 m (and to penetrate something like a T-72M1 or Al-Khalid ranges above 2,500 m will mean a very low kill probability).

In reality placement of EMES-15 main sight in Leopard 2A5/A6 was not changed, it is still placed in the same opening as in earlier variants. However main sight was rised thus allowing to close old "window" and install wedge shaped addon armor.

So in the end, weak zone was partially reduced, and armor protection in this place improved. However better would be to completely eliminate such main sight placement and place it instead, completely behind front turret armor, just like in M1A2 or Merkava Mk4.

The Reason i said, about it wrong placement is coz its at frontal Armour where most hits comes down, If its on top with fold-able option its better..

There are new ammo for Arjun MK2 including longer AP penetrartor, New HEAT made of CL-20 explosive, HESH may remain for anti-personal..

ok...the video posted by sayareakd shows the clearest view yet of Arjun's ammo casket, I don't see any armored panels covering them as in the M1A2, so would the blow off panels be of any use - from what I can make out is that in case of ammo cook-off the blast would basically be directed in the crew cabin & some of it would be directed out via the blowoff panels, but that probably may not be enough to save the crew, or am I wrong here ?
