Arjun-II MBT development l Updates & discussion.

[Dazzler]

A few observations...

* it weighs a whooping 68 ton with a 1400hp engine, movement in desert may prove difficult.

* ERA modules are exact same as K-5 not Relikt, bought of the shelf.

* The LAHAT guidance unit is mounted at the front turret, asking enemy shell come and disable me

* The composite cover seen on LAHAT guidance unit seems a good move, but ceveat is that one side has ERAm the other side has composite, ERA exlplosion will hamper composite module

* The RCWS mounted in the center, restricting gunner's/ commander's LOS (line of sight)

* The apfsds is the same as ever...

Arjunk is not even ready. Kind of weird they are making an update for a tank that is not even ready.

thank you for your valuable insight...take a print out of alkhali make a batti and you know what to do with it...

You bought the title with your knowledge buddy?? Really childish arguments... Next response from you will be prove me.. We know how to prove the same.. you will compare the same with AK with OT arguments in between... drags and fights.. I know it is not worth to prove the same.. In first case if you have done some Research you will not end up doing the same ... Atleast remove the LOS comment really not worth for the title you hold

dragging in unnecessary comparison is not my domain.

DRDO is not addressing some fndamental issues with the basic design, every improvement comes with a bundle of flaws with it. Seeing is believing, just see the pics.

This picture is an APFSDS round made by Mahindra Defence. Army uses OFB-built ones.

Seems lke they copied the design, L/D ratio and sabot from OFB MK-II round.

Maybe they outsourced production to Mahindra Defence.

 

[Dazzler]

you know pics dont speak for themselves.. a picture can bring lot of hypothesis which has currently happened to you.. how do you know there is flaw?? just by seeing pictures... are you oracle?

learn to speak in a proper manner first, post reported !

I believe i spoke the universal understanding on the pictures (i.e.) pictures inference merely bring hypothesis ... It means you can bring 1000+ logical conclusions from that.. In any way i am not there to provoke you.. I am just asking the explanation of your expertise on that..which i mean is not an offensive any way.... but a mere logical conclusion of our understanding for better arguments in the future

all my observations root from the pics of mk 2 shown here, its evident for any person who has general knowhow on mbt/ armour basics and understands how they work. No rocket science at all.

 

[Dazzler]

from the pic posted, things are visible.

* The armour cover for LAHAT guidance unit has a hole, this signifies that it is not a composite armour module block, rather just a hollow metal cover so protection from front against a apfsds or even a HEAT round is still questionable.

* ERA is directly behind the cover, though it offers good side protection but a shell hitting ERA module will end up in an explosion, which means, the blast on impact will also damage the LAHAT cover, hence, exposing the guidance unit.

* Front protection on the right side is same as before, exposing not only the commander's sight, but also ATGM sight, a bad decision.

* RCWS placed in the center, blocking the LOS of gunner, its never placed at the center but either at the right or left or even at the back.

The weight is 60 tonnes not 68,
Engine is Cummins QSK-38 turbocharged 1500 hp
That RCWS is not gonna be on the final version.
A few more modifications to go before final production model.

1> The 68T combat weight IIRC is with the mine plough. Only a few tanks in a formation will be equipped with these.
Same engine but reengineered transmission to deliver more torque (to handle the higher weight). Top speed is not an issue because to be honest, none of these tanks will ever be used at that speed in their operational area (the desert). At most, they will be at 20-30 kmph (max) to get accurate shots on the move (in fact ~20 kmph) and the important thing is the acceleration (from rest, to move from place to place, get out of trouble) for which the powerpack (engine and transmission) has been reconfigured
2>The production Arjun MK-2 will have a homegrown ERA package from HEMRL, not K-5, which has been in development http://www.hindu.com/thehindu/thscri...19/&prd=fline&
“We have developed a hybrid armour that can take care of tandem warheads and kinetic energy projectiles,” Appa Rao said.
From 2010:
The Tribune, Chandigarh, India - Main News

The Defence Research and Development Organisation (DRDO) has developed a specialised ‘hybrid’ armour that will make tanks safer in battle and somewhat immune to anti-tank missiles. The DRDO’s Pune-based High Energy Materials Research Laboratory (HEMRL) has worked on the new armour.

Dr A Subanandha Rao, HEMRL Director, said the hybrid armour would take care of tandem warheads and also kinetic energy projectiles aimed at tanks in the battlefield. It would increase the survivability rate of tanks........

The hybrid armours are likely to be used on the latest Russian-origin T-90 tanks and the indigenous Arjun tanks, Rao said, adding that the Army had been involved at every stage of testing and developing. since 2009 & even earlier.
3>Tank design is compromise at its best. Ideal situations are rarely if ever seen. If the CLGM/LAHAT module is not available
with an integrated sight, it has to be fitted into a module that can also offer some armor protection and has clear LOS. By enclosing the sight in another module with say passive armor, it will be protected against ERA detonation from nearby panels.
4>Not completely correct, as the COAPS provides much more visibility than before and the GMS remains as is, with a clear LOS. By putting a RCWS with its own integrated thermal imager, CCD, LRF- there are effectively 3 sets of surveillance sights for 3 crew - gunner, commander, loader. This makes the Arjun one of the tanks with a collection of independent sights for battlefield surveillance. The blind spot to the left of the COAPS can be covered by the RCWS sight.

Further, CVRDE has a RFP out for a new RCWS as well. A new design could be used for the loader and placed elsewhere. Refinements are possible.
5>Wrong

Broadsword: Upcoming modifications on the Arjun Mark II

5. Enhanced ammunition penetrator
7. Resin-based CCC

Arjun MK II main battle tank unveiled by Defense Research & Development Organisation of India.
The Defence Research & Development Organisation (DRDO) of India unveils the latest generation of its local-made main battle tank, Arjun MK II at Defexpo 2014, defense exhibition in New Delhi, India. The state-of-the-art ARJUN Main Battle Tank Mk II has been designed and developed by DRDO by incorporating numerous improvements over and above the ARJUN MBT Mk I which is already in service with the Indian Army.

It is endowed with superior fire power, high mobility and excellent protection characteristics required to fulfill the challenging battlefield requirements of the 2I Th. century. ARJUN MBT Mk II manifests the latest battle tank technologies that makes it a distinct front-runner amongst the array of contemporary Main Battle Tanks of modern armies the world over.

The superior armour defeating prowess of the ARJUN MBT Mk II gives it an edge over contemporary battle tanks of the world. A computer controlled Integrated Fire Control System incorporating day-cum-night stabilized sighting system guarantees a very high first round hit probability and reduced reaction time to bring effective fire on targets.

The main armament of the Arjun MK II is a 120mm rifled gun. The Arjun MK II carries a total of 39 rounds. Secondary armament consists of 7.62-mm MAG coaxial machine gun and a roof-mounted remotely controlled weapon station, armed with a 12.7 mm caliber NSVT heavy machine gun.

The all-round protection has been enhanced with improved KANCHAN armour. ARJUN MBT Mk-ll affords a higher degree of protection amongst the present generation of battle tanks. Protection was improved by adding locally-developed explosive reactive armor modules.

Thats why i said pics can bring hypothesis .. see in this ivew

It is clearly residing away from the block you assumed without disrupting the LOS...
