    ERA Mk-II developed for Arjun MK-2

    After integrated explosive reactive Armour, (ERA) system made its debut on Arjun MK-2 tank for protection from enemy missiles and rockets. DRDO has completed work on New ERA Mk-II (Hull and Turret panels) for Arjun MK-2 main battle tanks.

    Performance of ERA Mk-II developed by DRDO was demonstrated to Indian Army. Performance comparison test was also conduced last year in October where ERA system currently been used on Russian developed T-90 tanks was compared with DRDO developed ERA Mk-II . Both ERA system took direct hits from MILAN anti-tank guided missile and against 125 mm FSAPDS (AMK-340)
    ammunition at PXE, Balasore which was witnessed by Indian army officials .

    Performance of ERA Mk-II post test was found equivalent to ERA system used on T-90 main battle
    tanks. Defence Metallurgical Research Laboratory (DMRL) recently also has developed new
    Improved Kanchan Armour for Arjun MK-2 tanks.

    Explosive Reactive Armour (ERA) plates on the tank have boosted crew protection in Arjun MK-2, but also increased its weight by one and a half tonnes.

    A tank that is already 68 tonnes is now heavier Length: 10.64 m; Width: 3.95 m; Height: 3.18 m. thats half a metre wider(Can it get throught the railway tunnels!!!) and 80cm taller!

    Pressure on the Ground
    Arjun Mk-2 offers enhanced firepower, but it’s too heavy to go where the Army wants it

    __________________________________________________ _______ By Atul Chandra
    Avadi, Chennai: After more than three decades of development, India’s Arjun Main Battle Tank (MBT) has literally emerged like a phoenix from the ashes, surprising even its most sceptical observers. Last year, the Arjun outgunned the Indian army’s T-72 and T-90 MBT’s, when trials were conducted with the respective units putting up their best tanks and personnel.

    FORCE visited the Combat Vehicles Research & Development Establishment (CVRDE) for an exclusive insight into the programme. We learnt that while the Arjun Mk-2 is substantially improved and more capable than the Arjun Mk-1; it is too heavy, limiting areas where it can be deployed by the Army. And that renders it unsuitable for the army’s operational requirements for a Main Battle Tank (MBT). According to P Sivakumar, Director CVRDE, “the weight of the Arjun prevents it from being deployed in all the areas required by the Army”.

    Keeping this in mind, the Arjun Mk-2’s improved performance seems to have put the Army in a spot. What does one do with a tank that is fast, can shoot accurately on the move and is relatively well protected but is too heavy to be deployed in the deserts near the Pakistan border as a replacement for the T-72 or T-90? Paradoxically, while the tank itself has demonstrated high speed and mobility, its weight precludes it from being able to operate anywhere the army wants it to. The Arjun Mk-2 will weigh around 67 tonnes and this fatally limits the tank’s operational effectiveness for the Indian Army.

    The tank is too heavy to be deployed across the border with Pakistan. It is unable to effectively traverse terrain filled with natural and/or artificial obstacles. Or areas criss-crossed with rivers and canals. That rules out most places in Rajasthan, Punjab and the mountainous terrain of the J&K sector.

    NEW DELHI — Most of India's homemade Arjun Mark-1 battle tank fleet has been grounded because of technical snags and lack of imported components, an Indian Army official said.

    "Nearly 75 percent of the 124 tanks with the Army are grounded," the official added.

    The Army has inducted 124 Arjun Mark-1 tanks developed by the Defence Research and Development Organisation (DRDO) and produced by state-owned Heavy Vehicles Factory at Avadi in southern India. Nearly 55 percent of the value of the tank is imported components and those supplies have dried up, the official said.

    The Army official did not give details of the technical snags but said there are more than 90 issues.

    "The problems in the Arjun tank are mainly confined to its transmission system, targeting and thermal sights," the official added.

    "There are a number of issues related to functionality due to imported components, which seem to be bugging the Arjun Mark-1 fleet for some time now. The technical snags have reportedly led to much of the fleet remaining non operational, creating a void in the tank strength of the Indian Army," said Rahul Bhonsle, a retired Indian Army brigadier general and defense analyst.

    The Indian Army was forced to buy the 124 Arjuns by DRDO so that the Avadi factory would remain functional, the official said. He added that the Arjun Mark-1 has still not been cleared by the Army for combat because at 62 tons it is too heavy.

    Meantime, DRDO has developed the Mark-2 version, which has received satisfactory marks from the Indian Army in comparison trials with the Russian T-90 main battle tank. The Mark-2 weighs less than 50 tons and has 93 improvements over the Mark-1, and includes nearly 60 percent indigenous components, claimed a DRDO official.

    The Army has cleared 118 Mark-2 tanks.

    "If the experience gained from Mark-1 is utilized fully there should be lesser technical problems with Mark-2 at present though reports of trials do not suggest the same," Bhonsle said.

    The indigenous Arjun tank project began in 1974, and was originally aimed to replace Russian T-54 tanks, which have been retired, and more than 1,600 Russian T-72 tanks still in operation.

    The article is not 100% accurate as it claims the Arjun Mk2 is 50 tons when it is in fact 63
