    Very good news indeed, with the increase of the indigenous component the per unit cost of Arjun Tank should come down further.

    Any update on the ongoing Tank Engine development ? How far are we with it?

    Production of upgraded indigenous tanks by 2014


    New Delhi, Feb 14 (IANS) India will begin production of an upgraded version of the indigenous Arjun main battle tank (MBT) by early 2014, an official said here Monday.

    The Defence Research and Development Organisation (DRDO) is already readying the Mark-II version of the Arjun for its first summer and winter trials this year.

    Among the upgrades, the Mark-II tank would feature an indigenous engine that would replace the existing German engines of the 58-tonne Arjun Mark-I.

    The developments come within a year of the government sanctioning the Arjun Mark-II project last May.

    'In 24 months from now or early 2014, the Arjun Mark-II tanks will be ready for production,' the DRDO official said.

    The army has already ordered 248 Arjun Mark-I tanks for induction into its armoured regiments. The first lot of 124 tanks, for which the orders were placed on the Avadi-based Heavy Vehicles Factory (HVF) in 2004 at a cost of Rs.170 million ($4 million) each, have been handed over to the army.

    The army is now operating the 124 Arjuns as part of two regiments in the western sector and last May placed an order for an additional 124 tanks, primarily to keep the production line in HVF running before the Mark-II version is ready for manufacturing.

    The army gained confidence in operating the Arjun tanks, despite the initial hesitation, after the first two regiments were pitted against the Russian-built T-90 MBTs early last year in comparative trials in the desert terrain.

    The Arjuns had outsmarted the T-90s in all the parameters set for the trials and had prompted the army top brass to agree to inducting two more regiments.

    The Arjun Mark-II will have about a dozen changes from the first lot, being armed with missile firing capability through a laser homing device. Though this system had been tested on the Mark-I version of the tank about five years ago, it did not form part of the final design of the initial 124 delivered to the army, and nor will it be mounted on the second lot of 124.

    The system, they said, would have a range of about eight km, within which it could destroy enemy tanks after homing on to the target using a laser.

    Other modifications include better explosive-reactive armour for the tank to protect it from enemy missiles and rockets, improving the sighting facility to provide it a wider view of the battlefield, including night vision capability, and a better communication system.

    The Arjun Mark-II will have over 90 percent indigenous systems on board, except for some hydraulic and electronic systems.

    The Desert Ferrari


    WITH the Army in possession of 100 of the 124 Arjun Mark I Main Battle Tanks it had ordered, the Combat Vehicles Research and Development Establishment, the Defence Research and Development Organisation (DRDO) facility that designed and developed the tank, has good reason to feel proud and prepare with confidence for the greater challenges that lie ahead. The immediate task, though, is the development of the Arjun Mark II tank, which will have a total of 93 upgrades, including 13 major improvements. The Army has placed orders for 124 Arjun Mark II tanks as well, and like the Mark I tanks, these too will roll out of the Heavy Vehicles Factory (HVF), the CVRDE's neighbour at Avadi near Chennai.

    The CVRDE's biggest challenge yet will be the development of the Future Main Battle Tank (FMBT) and unmanned ground vehicles (UGVs). “We are in the process of preparing the requirements and specifications for the FMBT. We have launched technology development projects to improve its gun, engine transmission and suspension,” said S. Sundaresh, Chief Controller, Armaments and Combat Engineering, DRDO. The FMBT will have an indigenous 1,500 horsepower engine and it will replace the Army's existing fleet of imported T-72 tanks, renamed Ajeya.

    The UGVs will be used for surveillance, mine detection and reconnaissance of areas where nuclear, biological and chemical warfare agents have been used. “We will be launching a big programme on UGVs to meet the Army's requirements. A road map is being worked out in consultation with the Army on their development,” said Sundaresh. The completion of the Arjun Mark I project has brought a sense of accomplishment on the CVRDE's vast shop floors. The project was originally sanctioned in May 1974 at a cost of Rs.15.5 crore and a timeline of 10 years. The deadline and the cost were revised in 1980, 1987 and 2000. The cost at the time of the closure of the project in March 1995 was Rs.305.6 crore.

    Five formidable-looking Arjun tanks rolled out of the HVF premises on August 7, 2004, marking the culmination of a 30-year saga of struggle that battled technology denial regimes, the Army's constantly varying requirements, difficulties in organising field evaluations, increase in number of prototypes, and so on. On that day, M. Natarajan, then Chief Controller (Armament and Combat Engineering), DRDO and formerly CVRDE Director, who had been associated with the Arjun project from the beginning, said, “Weapons of this kind take a generation to build.… When the Army wanted us to design a tank comparable with those in the United States, Germany and France, we took it up as a challenge. We had little experience then.…” ( Frontline, August 27, 2004). Natarajan later went on to become Scientific Adviser to the Defence Minister and DRDO Director-General.

    P. Sivakumar, Director, CVRDE, narrated the Arjun saga. A few tanks were delivered to the Army's 43rd Regiment for trials. Five phases of these trials were held at Pokhran and Mahajan in Rajasthan in winter, when the temperature plummets to 5° Celsius, and in summer, when the mercury sizzles at more than 45° C, and on different kinds of terrain. The Army was keen that Arjun should be able to ford waterbodies. Each tank covered 5,000 kilometres and fired 500 rounds of ammunition.

    The Army wanted a third party to assess the tanks and called in experts from Israel. They subjected the tanks to more tests at the Mahajan range and were so impressed that they called it “a desert Ferrari”.

    Arjun Mark I has imported content of more than 55 per cent, which includes the engine and the gun control system, which are from Germany, and the gunner's main sight, which is from Belgium. The tank has an excellent weight-to-power ratio, good mobility and accurate firepower. It weighs 58.5 tonnes and compares well with different heavy class of tanks available in the world. It has indigenously developed “Kanchan” armour, which can defeat different kinds of ammunition, and a 120mm rifled gun besides a robust transmission system and a flexible hydro-pneumatic suspension. The remaining 24 of the 124 tanks ordered by the Army will be produced by June this year, Sivakumar said.

    As for Arjun Mark II, the CVRDE Director said the major upgrades would include missile-firing capability against long-range targets; panoramic sight with night vision to engage targets effectively at night; containerisation of the ammunition wing; enhanced penetration of Arjun's ammunition; a variety of ammunition; and a painted surface that will camouflage the tank.

    Other major upgrades, according to Sivakumar, are explosive reactive armour; an advanced air-defence gun to shoot down helicopters; a plough to remove mines; and an advanced land navigation system. Arjun Mark II will have sensors that can detect lasers fired by an enemy tank and alert the tank to fire smoke grenades that confuse the laser. The first prototype demonstration of Ajun Mark II will take place by June 2011. By 2013-14, the first batch of about 30 tanks will roll out of the HVF, said Sivakumar

    Development of Improved Indian Arjun Complete: DRDO

    By VIVEK RAGHUVANSHI
    Published: 23 Feb 2011 15:21

    NEW DELHI - India's state-owned Defence Research and Development Organization (DRDO) claims that it has completed upgrades on the Arjun tank, replacing existing German engines and transmission systems with homemade systems.

    The Mark-II Arjun will incorporate up to 90 percent of indigenous content, compared with 58 percent in the current model, a DRDO scientist said, and should be ready for induction by 2014.

    The Mark-II also will feature superior missile-firing capabilities, the scientist added.

    Conceived in 1973, the Arjun tank was behind schedule by more than 15 years, resulting in the Indian Army choosing the Russian T-90 tank as its main battle tank. The Arjun had to go through a series of trials and retrials before the Army announced the tank fit for duty. Last year, the Arjun Mark-I had to be put on comparative trials against the Russian T-90, after which the Indian Army finally concluded that the Arjun tank performed to expectations.

    Earlier, the Arjun faced problems concerning its fire control system and suspension, and its weight-restricted mobility.

    Last year, the Indian Army ordered an additional 124 tanks, bringing the total to 248.

    Main features of Arjun MkII

    # FMBT's engine will be two-thirds the size of Arjun Mark I MBT's engine and will generate 1,500-horsepower. First prototype of the indigenous engine would be ready by 2016. FMBT will weigh 50 tonnes.

    # Project to develop the transmission for the tank is being launched. Engine and transmission ( aka "Bharat Power Pack") will meet the FMBT's mobility requirements.

    # Volume occupied by the electronics package will be low.

    # A total of 93 upgrades, including the advanced air defence gun system for firing at attack helicopters. Missiles firing capability to destroy long-range targets and bring down attack helicopters.

    # Panoramic sight with night vision for the tank's commander. An automatic target tracking system to add accuracy when firing on a moving target.

    # Explosive reactive armor panel which will comprise explosives in metallic brick form. These bricks will be mounted all round the MBT. When the enemy ammunition hits these bricks, they will explode and retard the energy of the projectile. Tanks armor will not be penetrated.

    # Improvements in material, fuel injection and filtration technologies will contribute to the reduction in the engine size without compromising on power.

    # Indian Army has placed an intent for production of 124 Arjun-Mk II tanks.

    # Phase I, 45 tanks will roll out with 56 upgrades, including the missile firing capability and the commander's panoramic sight with night vision.

    # Phase II, the remaining 79 tanks, with all the 93 improvements, will come off the assembly line. “By 2013-14, the first batch of around 30 tanks will go out,â€￾ Dr. Sivakumar said.

    # 124 Arjun-Mk II tanks would cost Rs.5,000 crores.

    Technology giant

    With 52 laboratories spread across the country and staffed with 7,000 engineers and scientists, the DRDO is virtually an empire.

    COURTESY: CVRDE

    ARJUN MAIN BATTLE Tank Mark I during trials in the Rajasthan desert in December 2010.

    “THE Light Combat Aircraft [LCA] Tejas is the Indian signature on the sky.” This cryptic remark made by W. Selvamurthy, Chief Controller (Life Sciences), Defence Research and Development Organisation (DRDO), summed up the patriotic fervour that filled the hundreds of people present at the Hindustan Aeronautics Limited (HAL) airfield in Bangalore on January 10, 2011, as the indigenously built Tejas soared into the sky. As Tejas disappeared into the horizon, Defence Minister A.K. Antony handed over the “Certificate of Release to Service” to the Chief of the Air Staff, Air Chief Marshal P.V. Naik. This signals the grant of Initial Operations Clearance (IOC) to Tejas and means that the world's lightest fighter aircraft can now be produced at HAL. It was a moment to cherish.

    The 20-year struggle to build Tejas is a story of collaboration between the various laboratories of the DRDO. Its Aeronautical Development Agency (ADA) was the nodal organisation and the other agencies involved were the Aeronautical Development Establishment (ADE), HAL, Bharat Electronics Limited (BEL) and private units. V.K. Saraswat, Scientific Adviser to the Defence Minister, described the grant of the IOC as a new page in the history of Indian aeronautics. He was proud that during Tejas' 10 years of flight trials of 1,500 hours, there was not a single moment when the aircraft's safety record was in doubt. Today, 60 per cent of Tejas' components are indigenous, and by the time it receives its Final Operations Clearance, this figure will touch 75 per cent, said Saraswat, who is also DRDO Director-General. (Tejas is powered by a GE-404 engine imported from the United States).

    “Tejas is our technology. It means we can upgrade it any time,” Selvamurthy told Frontline. The Indian Air Force has placed orders for 40 Tejas aircraft, each of which will cost Rs.180 crore to build. The DRDO has already developed a two-seater trainer version. Work is under way on a naval version. Besides, feasibility studies are under way at the ADA on India's Advanced Medium Combat Aircraft.

    With 52 laboratories spread across the country and staffed with 7,000 engineers and scientists, the DRDO is virtually an empire. It is determined to empower the Army, the Navy and the Air Force with cutting-edge defence technologies. Its core philosophy is to make India's defence systems self-reliant. Its engineers and technicians work in diverse disciplines such as aeronautics, missiles, armaments, combat vehicles, combat engineering, ammunition, life sciences, agriculture, electronics including radars, nuclear-powered submarines, robotics, avalanche-arresting techniques, nanotechnology, materials and naval systems. Some statistics will reveal how successful the DRDO is in its march towards self-reliance. In the past seven years alone, the DRDO has developed systems whose production value has been estimated at Rs.1 lakh crore. These systems include a variety of missiles; the Main Battle Tank, Arjun Mark I; the LCA Tejas; nuclear, biological and chemical warfare (NBC) defence technologies; radar; sonar; rifles; sub-machine guns; armoured ambulances; infantry combat vehicles; robots; torpedoes; portable sitcom terminals; kits to detect viruses; parachutes; anti-fouling paints; anti-eczema cream; ready-to-eat food items for soldiers posted at Siachen; a cream to treat frostbite; and a herbal mosquito repellent.

    “Our spectrum of products is very wide. We cover the largest canvas in the country. But we have a specific user – the armed forces,” said Saraswat. Selvamurthy echoed his words. “From agriculture to the Agni missile to the Light Combat Aircraft, the DRDO has made a mark everywhere.”

    Out of the Rs.1,00,000-crore worth of systems put into production, Rs.600 crore worth of systems for NBC defence have been inducted into the Services. Both the public sector and private industries produce them.

    A country should be strong in four areas if it is to be able defend itself against NBC warfare. They are standard operating procedures with command and control centres to ensure smooth flow of information for a quick response; guidelines to handle the situation; trained manpower to detect the use of NBC warfare agents, demarcate the affected areas, evacuate people and decontaminate the area; and detection, diagnostic and therapeutic technologies for medical management of the catastrophe.

    “The DRDO has contributed to the country in all these four areas,” Selvamurthy said. Its scientists have helped formulate the guidelines framed by the National Disaster Management Authority for the eventuality of NBC warfare. Three DRDO laboratories – the Institute of Nuclear Medicine and Allied Sciences, New Delhi; the Defence Research & Development Establishment (DRDE), Gwalior; and the Defence Laboratory, Jodhpur – impart training to personnel in demarcating affected areas, evacuating people, protecting them and giving them medical help.

    The DRDO has developed an array of detection systems, including roentgenometers, pocket dosimeters and portable dose-rate meters to measure radiation doses; a nuclear instrument called the Radiation Detection, Measurement and Control (RADMAC) Unit to estimate gamma radiation; and gamma flash sensors to sense nuclear explosions. It has developed a portable gas chromatograph that is capable of detecting 20 chemical agents at a time.

    The DRDO has come up with a nerve agent detector too – a simple paper with three colours that can be used by anybody. All that soldiers have to do is to stick the paper on their clothing; the paper will change colour in the presence of any nerve agent.

    Cost-effective kits have been developed for diagnosing/detecting A(H1N1) swine flu virus, typhoid, malaria, anthrax, leptospirosis, chikungunya, dengue and the plague. These simple and sensitive instruments can be used by jawans and villagers. The DRDE developed the swine flu detection kit. R. Vijayaraghavan, DRDE Director, called the kit “a powerful tool”. It is much more specific and sensitive than the conventional kit developed by the World Health Organisation. The DRDO kit does not use sophisticated instruments but uses a simple technique called reverse transcription-loop-mediated isothermal amplification (RT-LAMP). More than 1,000 samples were analysed by the two kits. The samples missed by the WHO kit were detected by the DRDO kit, Selvamurthy said. This was confirmed by findings of the Indian Council of Medical Research (ICMR). While the WHO kit costs Rs.8,000 and takes eight to 10 hours to come up with its findings, the DRDO kit costs Rs.1,500 and gives results in about an hour.

    The technology has been transferred to Bigtec Labs, Bangalore, which has come up with a simplified, ready-to-go version of the kit. This version will go on trial at the National Institute of Mental Health and Neuro Sciences, Bangalore; the National Institute of Communicable Diseases, New Delhi; and the Postgraduate Institute of Medical Education & Research, Chandigarh. About 200 samples will be tested. “Tests are in progress and there is good correlation between the findings of the WHO kit and the DRDO kit. All queries from the Director-General, ICMR, are being answered for the final clearance of the kit,” Vijayaraghavan said.

    A bio-toilet developed by the DRDE, and produced by a private company, Escorts Railway Equipment Division, Faridabad, became a big hit during the recent Commonwealth Games held in New Delhi. The DRDE originally developed it for soldiers posted at high altitudes and in glacial areas. The efficacy of the bio-toilet, which uses a bacterial consortium to degrade human waste into carbon dioxide, hydrogen, methane and water, was proved during the Games. The toilets have been installed in all the coaches of the Bundelkhand Express.

    “The latest development is that the Lakshadweep administration has installed 21 bio-toilets in Lakshadweep, Kavaratti and Bangaram islands. The administration has placed orders for 10,000 such toilets. The bacterial efficiency is excellent and we have confidence in the system now,” said Vijayaraghavan.

    On the basis of the philosophy of “lure and kill”, the DRDO has developed a larvicide to combat the Aedes aegypti mosquito, which spreads chikungunya and dengue. Conventionally, larvicides are used in ponds, lakes and other waterbodies to prevent mosquitoes breeding.

    Selvamurthy explained: “But the DRDO did some path-breaking research in isolating the pheromone that is secreted by the larvae. The pheromones attract female mosquitoes to lay eggs (oviposition attractant).… We chemically synthesised the pheromone and combined the larvicide with the pheromone. So, it is no more a larvicide but an “attracticide”.

    It attracts the female mosquitoes, traps them in the waterbody and kills them.” The “attracticide” is environmentally safe. The manufacturing technology has been transferred to six private industries. The Central government has asked States in which dengue and chikungunya are endemic to use it.

    An iron removal unit (IRU) that can reduce the iron content of ferruginous water to WHO standards is also in the DRDO bag. The IRU is cylindrical in shape, about 1.75 metres tall and with a diameter of one metre. It can provide 300 litres of clean water an hour and is easy to install. It can cater to the needs of army barracks and small populations living in remote areas, where there is no access to treated water.

    The Defence Bioengineering and Electrochemical Laboratory (DEBEL) in Bangalore has developed a unique on-board oxygen generation system (OBOGS). It can administer the required quantity of oxygen at varying altitudes to pilots of fighter aircraft on long missions and prevent them from losing consciousness owing to severe gravity (G) forces. The innovation here is that oxygen can be administered on demand. The OBOGS forms part of the integrated life support system (ILSS) for fighter aircraft pilots developed by a team of scientists at DEBEL led by Director, V.C. Padaki.

    Since fighter aircraft can nowadays fly for an extended period because of the availability of mid-air refuelling facilities, the endurance of pilots has to concomitantly increase. If the aircraft were to carry several oxygen cylinders of the conventional type, the weight of the payload (missiles) would have to be reduced. In the ILSS, the nitrogen in air is removed, and the oxygen is concentrated, compressed and bottled in light-weight cylinders made of composites. The OBOGs keeps pilots' oxygen status at sea level even when they are flying at high altitudes.

    The ILSS has a component called the Demand Oxygen Regulator (DOR), which will ensure that oxygen is delivered to pilots as per altitude requirements and during the anti-G straining manoeuvres that pilots undertake during combat missions. This will economise the use of oxygen. According to Padaki, the contraption has a novel electronics unit that will ensure proper functioning of the OBOGS at changing altitudes and activate a back-up system in case of failure.

    The OBOGS will be tested in ground trials in Tejas after three months and will ultimately be integrated with it. The system will be customised for integration with Sukhoi-30, Jaguar, Mirage-2000 and MiG-29. “The IAF will definitely go for this system because it will cost less than the imported version,” Padaki said.

    The DRDO has developed an Unmanned Aerial Vehicle (UAV), Nishant, and a pilotless target aircraft, Lakshya. Both are under production. They will be used for battlefield surveillance and reconnaissance, target-tracking and correcting artillery fire. Nishant can fly uninterrupted for four hours and 30 minutes. The DRDO is proud of its UAV Vihanga Netra, which can monitor snow cover and avalanches in remote places, detect crevasses and help in mapping safe routes.

    The DRDO's latest UAV, developed at the ADE in Bangalore, is Rustom-1, a medium-altitude, long-endurance vehicle. It was successfully test-flown in October 2010 in the presence of Prahlada, Chief Controller (Aeronautics and Services Interaction), DRDO, and P.S. Krishnan, Director, ADE. It flew exactly as planned up to an altitude of 3,000 feet and remained airborne for 30 minutes. Rustom-1 can fly for about 15 hours at an altitude of 25,000 feet with a payload of 75 kg. It is a forerunner to the more advanced Rustom-H, a Rs.1,500-crore project, and the Unmanned Combat Aerial Vehicle (UCAV).

    “The future is in UCAVs for reconnaissance and surveillance. They will do actual combat. They will bomb and return to the base. They are reusable,” said Selvamurthy.

    Since naval warfare is highly complex and technology-intensive, the DRDO set up the Directorate of Naval Research and Development to coordinate the activities of the Naval Physical Oceanographic Laboratory (NPOL) in Kochi, the Naval Science and Technological Laboratory (NSTL) in Visakhapatnam and the Naval Materials Research Laboratory (NMRL) at Ambernath, near Mumbai. These three laboratories work towards making the Navy self-reliant in underwater weapons and they have developed an anti-submarine torpedo, Torpedo Advanced Light (TAL), which can be launched from ships and helicopters and has a speed of 33 knots an hour. It has a parachute system that ensures that it attains a touchdown velocity of 30-40 metres per second during helicopter launch. TAL has a state-of-the-art sensor package, an on-board computer, acoustic sensors, and so on, all indigenous and proved in sea trials.

    Another product the DRDO is proud of is Varunastra, a ship-launched anti-submarine torpedo. It has electric propulsion, advanced guidance algorithms, multi-manoeuvring capabilities over a long range, a deadly warhead and can reach a speed of 40 knots. A family of sonars named Humsa, Nagan, Ushus and Machendra have been developed and integrated with ships and submarines. The Advanced Panoramic Sonar Hull Mounted (APSOH) sonar system is the first to be indigenously developed for use in warships.

    The Aerial Delivery Research and Development Establishment (ADRDE) in Agra Cantonment specialises in developing a variety of parachutes for para-dropping troops, guns, combat vehicles, ammunitions and even for the recovery of UAVs. Some parachutes developed by the ADRDE can drop loads weighing four to nine tonnes from Il-76 aircraft. Brake parachutes are among the other products of the ADRE.

    They facilitate the safe landing of aircraft on short or snowy runways, and in emergencies or when there is an aborted take-off. In the Indian Space Research Organisation's recoverable satellites mission in January 2007, the ADRDE's three parachutes unfolded in a ballet-like sequence, one after another, over the Bay of Bengal and helped the satellite make a perfect touchdown in the waters.

    The ADRDE has diversified into lighter-than-air technologies and developed small and medium-sized aerostats. It successfully flew a medium-sized aerostat filled with helium gas several times over Agra in December 2010. These trials helped in keeping surveillance over Agra and intercepting a variety of communication.

    Prahlada praised the ADRDE for graduating from a laboratory that designed and developed balloons and parachutes to one that develops “systems of systems”. The aerostats, he said, would be useful for the three Services, the paramilitary forces and in civilian applications such as disaster management.

    A Combat Free Fall System helps paratroopers jump from high altitudes, glide long distances or land at specific spots. The system comprises a ram-jet parachute, an oxygen cylinder, jumpsuit, communication system and navigational equipment.

    The DRDO's Pune-based laboratories – the Research and Development Establishment (Engineers), the Armament Research and Development Establishment, and the High Energy Materials Research Laboratory – have rolled out massive contraptions such as Pinaka, the multi-barrel rocket launching system; Sarvatra that can lay a 75-m long and 25-m wide bridge in 90 minutes; the Amphibious Floating Bridge and Ferry System (AFFS), which can carry battle tanks and trucks across rivers; a bridge-laying tank (BLT), which is an avatar of the Main Battle Tank Arjun; Indian Small Arms System (INSAS) rifles; and propellants and ammunition for missiles, rockets, battle tanks, artillery and guns. A Sarvatra bridge can withstand 10,000 passes of battle tanks. The Army has procured more than one million INSAS rifles so far.
