    Discussions on Arjun MK2TANK are all based on weight. The Israel Merkava MKIV weighs 65 tonnes. The British Challenger 2 is 63 tonnes. The US M1 Abraham weigh 63 tonnes and in the war on Iraq 1135 participated and 530 were sent back for repairs. Arjun cannot be compared to T90 for weight as technology is superior. Even superior to Abraham. Arjun MK2tank is better than Abraham. A simple iranian anti tank missile was capable of destroying Abraham. Arjun has KANCHAN armour a ALWACS laser warning and counter measures system and thermal night vision which makes it superior to Abraham.

    The Armour Protection of Arjun MK2 consists of 3 layers. The primary RHA. Then Kanchan Armour at frontal arc and critical spaces , then ERA.

    The entire RHA is being changed , which will result in weight loss of atleast 5 tons.

    So from 68 to 63 tons atleast, will be good.

    India will perform for the first time at the Tank Biathlon competition in Alabin near Moscow on its T-90

    Indian tankmen will bring their T-90 tanks for the first time to the Tank Biathlon contest, which will be held within the framework of the third Army international games at the Alabino training ground near Moscow from July 29 to August 12, the deputy chief of the Main Directorate of Combat Training (GUBP) of the Armed Forces of the Russian Federation, Major Dmitry Gorbatenko.

    "In the tank biathlon for the first time on its technology, on the T-90 tanks, India will participate. Belarus will perform on four of its T-72 tanks, which underwent a deep modernization. Traditionally, China participates in all competitions in all competitions, "Major General Dmitry Gorbatenko said during a meeting with foreign military attachés from 32 countries.

    The deputy chief of the GUBP also noted that the remaining participants in the tank competition would receive Russian T-72 tanks. At the same time, participants of competitions in other countries have the right to use either their own technique or the technology of the host country. "Russian servicemen will participate in competitions on their equipment," Major General Dmitry Gorbatenko added.

    I am of the opinion that India must send its MBT Arjun. Let IA be made naked to the world.

    The Mk1 is facing spares issue and MK2 is still not ready, with a major change being taken to reduce its weight.

    So even if we want Arjun MK2 there, its not possible, atleast this year.

    However , this time we are going with T90 tanks, lets see how it fares against Type 96A.

    Lack of spares is history regarding Arjun.

    Track shedding was one of the main problems claimed by IA. But it was mainly due to inexperienced drivers who were used to Russian tanks mixing it up. The simulators are solving it.

    The process of obtaining replacement spares is time consuming, since there are a number of agencies involved. Limited production numbers further exacerbate the problem. Director Sivakumar explains that steps were being taken to tackle this problem and “unlike the Mk-1, where orders for the tank and the Engineering Support Package (ESP) were handled separately, in the Arjun Mk-2 this will be done simultaneously. That will reduce the time taken for delivery of the required items”. According to him, production has improved dramatically and an Israeli firm is now working on computerization of the line.

    Director, CVRDE, Dr Sivakumar, gives us the low-down on the Arjun programme.




    What is the status of the Arjun Mk-2 programme currently?
    The Arjun Mk-1 with a total of 89 improvements decided upon with the Army, is called the Arjun Mk-2. These 89 improvements have been made not only keeping in mind the concerns and issues faced on the Arjun Mk-1 tank but also to cater for future requirements of the army. At present, the army has decided to induct 118 Arjun Mk-2 tanks instead of 124. This is the result of a policy decision that will see the war reserve for all armoured regiments in the future being reduced by three. And so, two regiments of Arjun Mk-2 will be short of six reserve tanks. The indent for 118 tanks is almost in the final stage.

    The army has said that it will decide if it is satisfied with the Arjun Mk-2, only after the trials (which began last month and are expected to go on for two to three months) are completed. The Ordnance Factory Board (OFB) will require 30 months (2.5 years) from the placement of the order, for the first batch of Arjun Mk-2 to be delivered to the army. The Mk-2 will incorporate all that we learnt while battling issues with the Arjun Mk-1, in terms of production, performance, quality etc. CVRDE is working to ensure that whatever problems were faced by the Mk-1 will not be repeated in the Mk-2. Based on the Mk-2 programme, we have formed a core committee called the Arjun Core Committee that will monitor the progress of the Arjun Mk-2 on a monthly basis. All the stakeholders starting from the DRDO, the Directorate General of Quality Assurance (DGQA), the Corps of Electronics & Mechanical Engineers (EME) and the users, are present on the committee and we have obtained excellent support from all the stakeholders.

    What are the major changes in the Arjun Mk-2?
    The Arjun Mk-2 will see the tank weight increase from 62 to 67 tonnes, as a result of specific requirements from the user — which include additions such as the track width, mine plough and Explosive Reactive Armour (ERA) on the glacis plate, as well as the front of the turret. These two requirements alone will add three tonnes to the weight of the Arjun Mk-1. Along with other additions, the Mk-2 is expected to top out at 67 tonnes. We decided after studying the power pack (MTU engine with RENK transmission), that it is excellently suited for Indian desert conditions. We have steadily made this engine and transmission more and more rugged over the last many years, besides improving things like the air filtration system and cooling system.

    Hence, we have convinced the user that the same power pack, with a new final drive using a higher reduction ratio, can be used for the Arjun Mk-2. This was proved to the Army last year, when we drove 1350 km with the power pack modified to this standard and simulated weights of up to 66 tonne. We converted production vehicle P-1 into Mk-2 with 53 improvements, to obtain feedback. This tank took part in an exercise last summer that lasted almost two weeks, with temperatures of 46 degrees. We have improved the suspension — to provide the same life to components despite the increase in weight. To cater for this new suspension, we have developed a new hull for the Arjun Mk-2.

    The Mk-2 variant is now capable of firing missiles, which was not possible in the Mk-1. We had already proved the LAHAT missile as a standby. We are now integrating it on the Mk-2. Apart from that, the Mk-2 will feature a remote controlled weapon system atop the turret. In Mk-1, this required the loader to come out and fire the weapon. The Mk-2 will have an improved commander’s panoramic sight with night vision, hunter killer capability between the commander, gunner and loader. Auxiliary Power Unit (APU) which is not present in T series tank is present. It has been enhanced from 4.5 kW to in excess of 8 kW for the Mk-2. With regards to the Chassis Automotive System, we have digital communication systems, advanced navigation systems etc. We have increased the track width, to ensure that the ground pressure remains the same in spite of the increased weight.

    What is the status of the Arjun Mk-1 at present?
    The Arjun Mk-1 received orders for a total of 124 numbers. The two regiments equipped with 45 Arjun tanks each, are the 43rd armoured regiment and the 75th armoured regiment at Jaisalmer. The Arjun is fully operational with these two regiments now. The balance 34 tanks will be used to meet the Army’s BRIC requirements and these are spread across the Corps of Electronics & Mechanical Engineers (EME), war reserve, training establishments, DRDO/DGQA etc. Heavy Vehicles Factory (HVF) Avadi has dispatched 116 Arjun Mk-1 tanks. The remaining eight tanks will be delivered over the next five to six months.

    Most of the spares for the Arjun MBT were consumed during the various trials. We are now working to ensure availability of fresh spares. The other part is the Engineering Support Package (ESP) for the Arjun which includes spares, training and training aids. This is being done in parallel. As far the Arjun Mk-1 is concerned, about 90 percent of its tasks are complete.

    What is the cost of the programme till date?
    Each Arjun Mk-1 costs Rs 20 crore plus. Each Arjun Mk-2 with all improvements will cost approximately Rs 34 crore. The Arjun Mk-1 programme cost approximately Rs 360 crores. With that money, we made 11 prototypes and 15 pre-production series tanks and the required spares. This included the cost of creating the production line. We are looking at a number of variants based on the Arjun platform, such as Armoured Repair and Recovery Vehicle (ARRV) which is close to finalization. We are also looking to use the Arjun chassis to mount a Russian 130 mm Catapult gun, which was earlier mounted on the Vijayanta chassis. We will also be competing for the Indian Army requirement for a self propelled, tracked gun. We will offer a Slovakian 155 mm gun mounted on the Arjun along with Bharat Earth Movers Limited (BEML).

    We have also built the Arjun Bridge Laying Tank (BLT) but the Army says it may not be required. The cost per tank will certainly go down if we get more orders. This will help reduce the import content as well. The Mk-1 has nearly 60 percent imported content and even though there is a lot of value addition being done, the import content will remain the same for the Mk-2.

    Since the size of the order is small, no foreign company is willing to offer Transfer of Technology (ToT). I feel that if the Mk-2 is ordered by four regiments, then the import content could go down to 43 per cent and further down to 25 per cent if orders are placed for a total of six regiments. The lifecycle costs of the Arjun will be much cheaper than other tanks. The programme has also been able to offer numerous improvements to a number of indigenous programmes and armoured vehicles in service with the army.
