    Details of Arjun mk II programme from Col Ajai Shukla. With all those upgrade Arjun became a hi-tech killing machine. Lots of info about the exterior, sighting and self defence systems but waiting for details on the new 1500 HP engine and Mobile Camouflaging System (MCS).



    Upcoming modifications on the Arjun Mark II



    Folks,

    I know, like every married person, that “major” and “minor” are relative terms. But here is the list of 19 major modifications that the Arjun Mark II will feature. The list was finalized after extensive user opinion canvassing and feedback from the DGQA, DGEME, OFB, other DRDO labs.


    1. Missile firing capability
    2. Commander’s TI panoramic sight Mk II
    3. Driver’s uncooled thermal imaging night sight
    4. Additional ammunition (don’t ask… won’t tell!)
    5. Enhanced ammunition penetrator
    6. Effective alternative to muzzle reference sight (MRS)
    7. Resin-based CCC
    8. Ten-round containerised bin
    9. Explosive reactive armour panels
    10. Infra-red/Thermal imaging resistant paint
    11. Air defence weapon remote firing
    12. ALWCS (advanced laser warning and countermeasure system)
    13. Roof mounted driver’s seat
    14. ATT in GMS (gunner’s main sight)
    15. Advanced land navigation system
    16. New final drive with increased reduction ratio
    17. Advanced running gear system
    18. New track system
    19. Mine plough



    In addition, there are 74 “minor” improvements (adding up to 93 improvements in all) that are not really that minor. For example:

    1. An improved sprocket wheel that modifies the manufacturing process from rolled homogenous armour (which required gas cutting and machining) to a forged sprocket which is 50% the cost, 50% easier to build and gives a longer life.

    2. Another minor modification is the incorporation of stainless steel fuel tanks. The painting required for the insides of the earlier mild steel tanks was creating residue that clogged the fuel lines and filters. But stainless steel requires no painting.

    3. Internal electrical wiring has been comprehensively re-laid, incorporating the dozens of modifications that have been incrementally carried out over the years. The wiring has now been laid systematically, making it easier to track and repair.

    4. The radio harness has been modified, and internal communications are now digital. That makes it easier to integrate audio alarms and provides an SMS facility between the crew (how ‘bout sum chai?). It is totally noise free… now the crew can communicate easily.

    5. Another improvement is the incorporation of a new compact Auxillary Power Unit (APU), which provides 8 KW of electrical power (uprated from the existing 4.5 KW APU). This requirement is based on fresh load budgeting calculations, allowing the tank to operate in “silent mode” with the additional electronics… also keeping a cushion for future electronic enhancements.

    Of these 93 modifications, 45 have already been tested during trials in summer 2011… having been incorporated on one "improved Arjun Mk I" tank. A second tank is being cut open to put in three major modifications, including the commander’s panoramic sight Mk II.

    Broadsword: Upcoming modifications on the Arjun Mark II

    I think this system has automatic target tracking system as electro-optical sights are coupled with the machine gun.

    This is one cool feature of the mk II. Laser and IR guided missiles poses serious threats.

    The Mobile Camouflaging System (MCS) will also reduce the IR signature.

    Simple the driver's seat hanging from the roof.

    I think it is a testbed for mk II. Some improvements are tested on this.

    Arjun tank hull and turret has been modified to achieve the target weight of about 55 tons from 59-64 tons. Elbit is helping to enhance its firepower and battlefield survivability and IMI is helping to augment Arjun Mk II’s mobility, redesign its turret and hull and improve its production-line processes told Rahul Bedi, Jane's correspondent

    That is BS proven by Col Shukla. The weight has increased more, not decreased. DRDO put a more powerful engine.

    So they are leaving the sides of the turrets under protected with just 90-110mm RHA plate!!That portion should be upgraded to 350 mm composite armor like the first 1/3rd portion of turret.And there was report of redesigned turret with wedge shaped add on armor like Leopard 2A6,what happened to that??
    By the way,the ARDE L52 rifled gun is currently the strongest in the world.
    2A46 M5-6500 Bar
    Rheinmetall L44/M 256-7100 Bar
    Rheinmetall L55-7600 Bar
    ARDE L52-860 MPa=(860X10)Bar=8600 Bar
    ROF L30-6200 Bar
    This should end the hoax that Arjun's gun is of UK origin.Don't know how did the ARDE managed to develop something like that.

    By complete and utter chance, or maybe they got lucky and scored a talented scientist or two that didn't head off to the private sector.

    Definitely not through sponsoring a innovative work environment with strong work ethic.

    bro I repeatedly mentioned many times that there will be no change in basic configuration of arjun mk I. We will see extra systems above mk I, which will make it mk II. except the superstructure entire system is new though.

    120 mm rifles gun of arjun is one of the best in the world. DRDO is a pioneer in material and armaments technologies, nothing surprising.

    One of the strongest. :) The multi-layer protection system and weapons firing capabilities are excellent.
