Arjun (Sanskrit: अर्जुन) is a main battle tank developed by India's largest defense contractor, the Defence Research and Development Organization (DRDO), for the Indian Army. The tank is named after Arjun, one of the main characters of the Indian epic poem, the Mahabharata.

Although the development of the tank began in 1972 by the Combat Vehicles Research and Development Establishment (CVRDE)[3], it was only in 1996 that the Indian government decided to mass produce the tank at DRDO's facility in Avadi.[4] However, the first five units were not delivered until 2004.[5] Meanwhile, the delays from 1990s to 2000s and failures in the Arjun project in 2005 , 2006, 2007 Trials prompted the Indian Army to order vast numbers of T-90S tanks from Russia to meet the defense needs that the Arjun had been expected to fulfil.[4][6] In 2008 reports suggest that Indian army is "satisfied" with the performance of Arjun. After the Winter 2008 trials, the Indian Army chief, wrote to the defense ministry appreciating the tank's performance. In the letter he stated that "the tank was subjected to the most strenuous of tests and it performed 'admirably' well".[7]

The Arjun features a 120 mm main rifled gun with indigenously developed APFSDS ammunition which has capability of defeating superior armor, one 7.62 mm coaxial machine gun, and a 12.7 mm machine gun giving the tank an edge over contemporary world tanks. It is powered by a single MTU multi-fuel diesel engine rated at 1,400 hp, and can achieve a maximum speed of 70 km/h (43 mph) and a cross-country speed of 40 km/h (25 mph). It has a 4-man crew: commander, gunner, loader and driver. Automatic fire detection and suppression, and NBC protection systems are provided. All-round anti-tank warhead protection by the newly developed Kanchan armour is claimed to be much higher than available in present third generation tanks.[4]

History

Initial plans and development

Defence Research and Development Organization (DRDO), with Combat Vehicles Research and Development Establishment (CVRDE) as the main laboratory, was tasked with developing the hull, armor, turret, running gear and gun, with the powerpack being bought from abroad.[8]

Despite DRDO's attempts at indigenization, the Arjun relied heavily on foreign components and technology. DRDO received major design assistance from Krauss Maffei, the developer of the German Leopard 2 tank, and several other German firms. As a result, Arjun's design is very similar to that of Leopard 2A4 tank.[9] 50% of the tank's components are imported, which include the engine, transmission, gun barrel, tracks, and fire control system[10]. Recent reports from India indicate that the Russian T-90S will form the mainstay of its future force, despite that tank’s performance issues in hot weather. At the same time, the Indian Army wants to cap production of indigenous Arjun tanks to 124 units, due to repeated trial failures and vast budget overruns.[11]

The Arjun project has experienced serious budget overruns and repeated delays that resulted in a protracted development time of more than 37 years. While the government sanctioned Rs. 15.5 Crore for the initial part of the programme in May 1974,[8] by 1995, DRDO had spent Rs. 300 Crore, due to changing requirements and inflationary cost increases.[12] This was one of the highest over-run by percentage for any DRDO project.[13]

Production

The Indian Army ordered 124 Arjuns in 2000.[14] The first five were delivered to the army in August 2004.The cost of 124 Arjun MBT will be around $471.2 million.[1]

Maiden Regiment

In May 2009 the Indian Army raised its maiden Arjun regiment. The army received 16 tanks from Combat Vehicles Research and Development Establishment (CVRDE), Avadi, Tamil Nadu, taking the number of tanks delivered so far to 45. The Arjun will be pitted against the Russian T-90S during trial exercises in October-November 2009 to assess its operational capabilities.[15][16]

W. Selvamurthy, chief controller of research and development at the DRDO said "These 124 tanks are in various stages of production. All of them will get inducted into the armed forces in March and April ... Other organisations are also giving us orders", adding that a few tanks have already been handed over.[17]

Visualisation with Enhanced Digital Elevation Model and Soil Profile Analysis for MBT Arjun Simulator (VEDSAR)

After the criticism of Mobility of Arjun MBT, DRDO has have completed Visualisation with Enhanced Digital Elevation Model and Soil Profile Analysis for MBT Arjun Simulator (VEDSAR).VEDSAR involves how the main battle tank Arjun performed in different kinds of terrain.It uses data from [[CARTOSAT-1|Cartosat-1A].It will help in building a new project named Vehicular Interaction with Soil for Trafficability Assessment and Route-decision Aid (VISTAR).It provide the Army with information on the shortest possible distance between two points, the kind of obstacles present on the terrain.[18]

"We are interacting with the Army and we have demonstrated our capability in these areas. Future warfare will be based on DEMs. Cruise missiles will fiy on elevation models. So knowledge of DEMs is crucial," V.K. Panchal told to frontline paper.This project was started due to unavailability of computer software that was not available in the market.."The inputs include space-borne data plus ground truths," he told to frontline paper.[18]

Latest Development

File:Arjun MBT model.jpg
Arjun Tank model

DRDO is continuing to develop some new technology systems for MBT Arjun.[10]

  1. Automatic target locating, tracking and destruction.
  2. DRDO is developing the Tank Urban Survival Kit which is a series of improvements to the Arjun intended to improve fighting ability in urban environments which includes defensive aids like laser warning, IR jammer, and aerosol smoke grenade system.[19]
  3. DRDO also plans to develop robotic vehicles that will work on tele-link in addition to make the tracking of targets automatic.
  4. CVRDE is in the process of developing tank simulators.
  5. A new improved 1500 hp engine.[20]
  6. Addition of Slope Armor in front region like in Leo2A6M.
  7. An anti-helicopter round is under development as well.[4]

Specifications

Weighing in at 58.5 tons, the Arjun tank is significantly heavier than the Soviet-legacy tanks used presently by the Indian Army, and requires changes to the army's logistics establishment, including new rail cars to transport the bigger and heavier Arjuns. The required logistical changes are also being made but the cost of the whole Project is very expensive.

Armament

LAHAT
LAHAT

Armed with a 120 mm rifled gun, the Arjun is believed to be capable of firing APFSDS (Kinetic Energy) rounds, HE, HEAT, High Explosive Squash Head (HESH) rounds at the rate of 6-8 rounds per minute and the Israeli semi-active laser guided LAHAT missile. In addition, it is armed with a 12.7 mm AA machine gun and a 7.62 mm coaxial machine gun.[21] The Arjun can carry 39 rounds in special blast-proof canisters. Loading is manual.

The Arjun's rifled main gun is a rarity, main battle tanks of most other countries have smoothbore guns as standard. The British Challenger 2 is the only other MBT equipped with a rifled gun. Trials were conducted with the smoothbore Rheinmetall 120 mm gun.

Fire control and Navigation

Fire control and navigation technologies are provided by Elbit, an Israeli defence company. The Fire Control System is stabilised on two axes, and with an extremely high hit probability (design criteria call for a greater than 0.9 Pk) replaces an earlier analogue one, which had problems due to its inability to function under the harsh desert conditions. However, the new fire control system also frequently malfunctions when subjected to temperatures greater than 42 degrees Celsius.[22] The combined day sight from Bharat Electronics Ltd. and the thermal imager (formerly from Sagem, now reported to be from El-Op) constitute the gunner's primary sight. The first batch of tanks of the 124 ordered by the Army will have an all-digital Sagem FCS, whereas the second block will have the BEL unit, which will be used for all units thereafter. The commander's own stabilised panoramic sight allows him to engage targets and/or hand them over to the gunner. The Arjun has an auxiliary power unit to operate weapon systems in silent watch mode as well.

The tank incorporates GPS based navigation systems and sophisticated frequency hopping radios. The state-of-the-art Battlefield Management System, co-developed by DRDO and Ebit Israel, allows it to network with other fighting units. The Arjun has the capability to network with other tanks, thanks to its Battle Management System. In a search and engage operation, several Arjun Tanks can monitor an opponent and his moves, and try to eliminate him in a chase or ambush.

Protection

The turret and glacis are heavily armoured and use "Kanchan" ("gold") modular composite armour. The Kanchan Armor got its name from Kanchan Bagh, Hyderabad, where the Defence Metallurgical Research Laboratory (DMRL) is located.[23] The armour is made by sandwiching composite panels between Rolled Homogenous Armor (RHA) to defeat APFDS or HEAT rounds. During the trials in 2000 ,the Kanchan was able to withstand a hit from a T-72 at point blank range, and was able to defeat all available HESH and FSAPDS rounds, which included the Israeli FSAPDS rounds.[23] A new honeycomb design non-explosive and non-energetic reactive armour (NERA) armour is reportedly being tested on the Arjun.[24]

Mobility

The engine and transmission are provided by German companies MTU and Renk respectively.[25] The water-cooled engine generates 1,400 hp and is integrated with an Indian turbocharger and epicyclic train gearbox with four forward and 2 reverse gears.[26] A local transmission is under trials and will envisions to ultimately replace the Renk-supplied unit.[25] The tracks which were being supplied by German company Diehl are now being manufactured by L & T, an Indian company.[25] The cooling pack has been designed for desert operations. The Arjun has a lower ground pressure than the lighter T-72, due to its design.[25]

The Arjun has a state-of-the-art hydro-pneumatic suspension.[27] This coupled with the Arjun's stabilisation and fire control system allows the tank superb first-hit probability against moving targets while on the move.[27] Its ride comfort is highly praised.[27] Though on the negative side, it is a more maintenance-intensive and expensive system, even if more capable than the simpler and cheaper torsion bar system utilized on many older tanks worldwide.[28] During trials, the Arjun showcased its fording capability, by driving under 6 feet of water for 20 minutes.[29]

A new 1500 hp engine is being developed that will eventually replace the present engine. An allocation of 40 crore Rupees has been allocated for the project which is expected to be completed within five years.[30]

Trials and exercise

July 2005

During the summer trials in 2005, it was reported that the Arjun suffered major problems with its main gun sight, suspension system, and fire control system. Moreover, engine failures occurred commonly in temperatures averaging 55-60 degrees Celsius.[31]

Summer 2006

There are conflicting accounts of Arjun's trial results in 2006. In 2007, Major General H.M. Singh, a director in charge of trial and evaluation, said that the last year's user field trial report had certified that the accuracy and consistency of the weapon system was proved beyond doubt."[32][33] However, the 2006 army trial results showed that "the decade-old problems of overheating persist" and that "tank’s main subsystems, the fire control system (FCS) and integrated gunner’s main sight, which includes a thermal imager and laser range-finder, are rendered erratic and useless by the Arjun’s abnormally high peak internal temperature, which moves well beyond 55 degrees Celsius. This is in testimony to the Parliamentary committee."[34]

Exercise 2007

The Arjun tank was fielded during the Ashwamedha exercise in the deserts of Rajasthan.[35] The army was extremely unhappy with the tank, citing 14 defects that included "deficient fire control system". "inaccuracy of its guns", "low speeds in tactical areas", and "inability to operate over 50 degrees Celsius".[36]. "The Army is now faced with a troubling prospect: inducting a lumbering, misfiring, vintage design tank like the Arjun, and that, too, in large numbers"[34]. This, after DRDO over-shot Arjun’s project deadline by 16 years — from 1984 to 1995, finally closing the project only in 2000 — and the cost over-run is almost 20 times the original estimate. This is the highest percentage over-run for any DRDO project.[34]

September 2007 winter trials

Starting with the September 2007 winter trials, the Indian army deemed Arjun's performance unsatisfactory, including at least four engine failures.[37]

DRDO, on the other hand, insisted the tank was a viable choice for adoption and suggested the unsatisfactory performance of the engine during the winter trials was due to sabotage.[6]

2008 summer trials

Auxiliary User Cum reliability trials (AUCRT) of the Arjun MBT was conducted from September 2007 to summer of 2008. In a report to the Parliamentary standing committee the Indian army deemed Arjun's performance unsatisfactory, including four engine failures within only 1000 kilometers.[38] The defense minister presented this report before the parliament, later published by Press Information Bureau Government of India (PIB).[39]

The Army wrote in the report that during the "accelerated user-cum-reliability trials" in 2008, the Arjun "was found to have failure of power packs, low accuracy and consistency, failure of hydropneumatic suspension units, shearing of top rollers and chipping of gun barrels".[12] Sabotage was suspected, but the Army rejected that any sabotage happened during the trials.[6][40]

A later report published by the Government of India during the induction ceremony of the Arjun tank, confirms the success of the trial.An independent evaluation of the tank by a reputed tank manufacturer found that the the MBT Arjun is an excellent tank with very good mobility and fire power characteristics.[41]

DRDO has installed a black box-like instrument in the indigenous main battle tank (MBT) Arjun, under development for nearly 36 years, following attempts to "sabotage" its engine. The instrument was installed after the Indian Army termed the September 2007 winter trials of the Arjun tank a "failure".Attempts to sabotage the trials of the Arjun tank have failed after the black box was installed, said authorities.[42]

A different path

In September 2008, the Indian Army signed a deal with Russia to import 347 T-90 tanks and license build a further 1000.[43][44][45] Transfer of key T-90 technologies has also been agreed upon as a part of the deal.[46][47][48]

In 2008, the Indian Army announced plans to acquire an entirely new main battle tank unrelated to the Arjun, to be inducted after 2020.[49] The Indian Army has held an "international seminar on future MBTs", during which the parameters and requirements of this future MBT were identified.[49] As a result, Russia has offered to team with India on developing this future tank.[50][51] These developments do not bode well for the future of the Arjun project.[52][53]

According to Jane's, the Indian Army has confirmed that the Arjun's production will be capped at 124 units. Lt General Dalip Bharadwaj, the Director General for the Mechanized Infantry, said that "Army will place no more orders for Arjun beyond 124 that was already contracted", because the "Army is now looking 20 years ahead and wants a futuristic MBT."[6][54] Later in the year 2009, during the handing over of Arjun tanks, he said that the joint effort and the will to succeed against odds displayed by various agencies in putting out MBT Arjun proved to the world that India was a force to reckon with when it came to weapon design capabilities. The Army, which was proud to possess the tank, was confident that MBT Arjun would rank among the best tanks in the world.[55]

Winter 2008

According to the transcript of the testimony to the Indian Parliament by the Defense Minister, the Arjun's latest defects have been rectified "periodically", and the army has "categorically" indicated Arjun's performance as satisfactory. 124 Arjun tanks will be inducted into the army, "one regiment by the end of this year (2008) and the next regiment by the summer of next year (2009)".The Arjun is to undergo comparative trials against the Indian Army's Russian-built T-90 tanks in June 2009.[56] This is seen as a desperate, last-ditch effort to save the Arjun project, which requires an order of at least 500 units to make it feasible.[56]. Retired Lt. Col. Anil Bhat, a strategic analyst, pointed out that “the Arjun tank is cumbersome for strategic movement, i.e. to be taken from one sector to another. It is too wide and too heavy to be moved in the railway carriages that we have in India. The comparative trials are just an eyewash as Arjun can be compared to T-90" owing to the different weight class of both tanks.[56] This comment by Lt. Col. Anil Bhat was made without realizing that Arjun specific rail wagons have already been inducted in 2006.[57] Recent reports suggest that Indian army is "satisfied" with the performance of Arjun. After the Winter 2008 trials, the Indian Army chief, wrote to the defense ministry appreciating the tank's performance. In the letter he stated that "the tank was subjected to the most strenuous of tests and it performed 'admirably' well".[58]

Variants

  • A 155 mm self-propelled howitzer variant of the Arjun (labelled 'Bhima') has been prototyped by fitting the South African Denel T6 turret, which comes with the G5 howitzer to the Arjun chassis. This project has been delayed as DENEL has become embroiled in a corruption scandal in India, and hence the Indian Ministry of Defence has suspended the Bhim.
  • A bridge layer tank (BLT) based on the Arjun chassis has also been displayed by the DRDO[59]. Developed in cooperation with Indian industry, this bridge layer is deemed superior to the T-72 based units, as it can handle a larger load and uses a "scissors type" bridgelaying method, which does not raise the bridge high up into the air, and hence make it visible from afar.India’s main battle tank, Arjun, has taken the “avatar” of a bridge laying tank (BLT). The R&DE(E) did this by replacing the tank’s gun and turret with the bridge launcher. The bridge is cantilevered over chasms or across rivers to cover a distance of 26 m with a width of 4 m. The BLT-Arjun carries two halves of a bridge. At a wet or dry gap, the launcher slides the two parts and docks them to each other in such a way that the far end of the second half touches the other bank. The BLT then crosses the bridge, turns around, retrieves the bridge after undocking its two halves, folds it and is ready to move with the armoured column.[60]
  • Armoured engineering vehicles based on the Arjun are also assumed to be in development, as the Arjun induction will require units of a similar power to weight ratio or powerful enough to tow it, or recover it on the battlefield.
  • Tank EX: A new tank obtained by coupling a T-90 chassis and an Arjun turret. Only prototypes have been built so far.
