<b>Defence Institute of Physiology & Allied Sciences (DIPAS) - Historical Background</b>
Defence Institute of Physiology & Allied Sciences (DIPAS) was officially established on 20th September 1962. In India, research in military physiology was initiated in the year 1950 through a small group of scientists and medical physiologists within the realm of Defence Science Laboratory, Delhi. In 1962, with the thrust area identification of high altitude physiology, nutrition and biochemistry of human in severe stress environment and also with the urgent need felt for ergonomic assessment of workstations and man-machine interface, a full-fledged laboratory was established. In 1968, the laboratory was relocated within the premises of Army base Hospital, Delhi Cantonment. In the year 1993, the lab was shifted to its present permanent premise at Lucknow Road, Timarpur, Delhi.

During the early years, DIPAS has contributed extensively in all major areas of immediate application to defence operation, viz. ration scale and nutrition of soldiers sizing clothing, load carriage and distribution in infantry soldiers, thermal comfort zone identification, nature of heat casualty, salt & water requirement in summer, habitability survey of naval ships and physical training and conditioning schedule. While continuing with these issues related to immediate operational needs as faced by the users, research studies also emanated in tune with the time and the emerging technology. Extensive research work was carried out on yoga and adaptogen as performance enhancer in extreme environment, body water distribution on heat induced hypohydration and its correction, neurophysiological mechanism of HAPE, development of protective mechanism against noise induced hearing loss and thermal evaluation of protective clothing.

Today, DIPAS is a leading laboratory in physiology and biomedical research in the country with the primary mandate of promoting human performance in extreme environment of Defence operation. With 50 scientists, 200 technical officers & support staff members and 30 research scholars in its strength and a very specialised infrastructure, it has its characteristic research abilities to conduct studies on human volunteers in actual field conditions and in laboratory simulated environments. Its Ergonomics lab with Motion Analysis and Force Plate System has developed into a state of art competency in biomechanics research. Animal models are used for invasive organ system studies. Cell line research has been inducted for biological screening of plant extracts of interest in Program Charak: Herbs for Health of Armed Forces. Other program in hand viz. Biotechnology 2000 and studies on molecular mechanisms of acclimatisation employ molecular biology tools extensively. The laboratory has an elaborate networking with the biomedical agencies and academia within the country and abroad.

BrahMos now moves toward the air version

Yet another milestone was crossed by the supersonic BrahMos cruise missile on April 22 when it was successfully test-fired for the 14th time from the Integrated Test Range at Chandipur-on-Sea. The fourth and final test of the Army’s Land Attack Cruise Missile (LACM) validated the missile’s unique manoeuvring ability both at the boost and terminal phases during the 290km flight.
Explained, this means that the LACM can change its course (azimuth) at the initial boost phase as well as within 50km of the target. Even as BrahMos is a supersonic missile that travels at three times the speed of sound at 2.8 Mach, the manoeuvring capability will confound the enemy to know the direction from which the missile has been fired. With this successful test, the President Dr APJ Abdul Kalam himself has agreed to hand over the first batch of BrahMos LACM to the army sometimes in June, well ahead of the delivery schedule. The army had placed the order for one subgroup (12 launchers distributed in four Mobile Autonomous Launchers each with three BrahMos) in March 2006 and the delivery was agreed for middle-2008.

The BrahMos Chief Executive Officer and Managing Director, Dr A. Sivathanu Pillai told FORCE that, “BrahMos is a technological breakthrough that will make war winning possible in quick time. There is no equivalent missile in the world with similar capabilities.” What Dr Pillai did not say is that BrahMos is a psychological breakthrough as well; this is the only Defence Research and Development Organisation product that has been delivered before time.
The government in 1999 gave funding for the BrahMos, the first anti-ship version was test-fired in 2001 and after 10 successful test flights the missile was accepted by the Indian Navy in 2004. Simultaneously, work started on the army and the air force version; the first will be delivered soon and the recent visit of the air force chief, Air Chief Marshal F.H. Major to the BrahMos complex in New Delhi suggests that work on BrahMos air version is well on its way. All this has been possible because of good management, transparency and close interaction between the scientists and the users that has been the hallmark of this development work.

With a total of four tests, two each from the ITR and in Pokharan ranges, all technical parameters of the LACM have been validated. These essentially include the handling of the weapon system by the user (army personnel fired the missile independent of the scientists from their complex itself), midcourse guidance by the strap-down Inertial Navigation System housed in the on-board computer, terminal guidance by the seeker, manoeuvring capability of the missile at the boost and terminal stages, the advertised 290km range, and importantly the precision hitting of the target (the missile has demonstrated zero Circular Error Probability). In short, the requirement of the army has been met beyond its stated Qualification Requirements that are minimal acceptable technical capabilities.


LRDE working on Rajendra III radar

9 May, 2007
Electronics & Radar Development Establishment (LRDE) a unit of Defence Research and Development Organization (DRDO) has embarked on developing advanced version of indigenous Rajendra II radar and is called Rajendra III. Rajendra III is indigenous slewable phased array radar. The BLR-III vehicle on T-72 chasis is ready for track test. Phased array antenna has been fabricatedin Bharat Rlectronics Limited (BEL), Ghaziabad.

Collimated beam pattern and s/s cure for all 16 spot frequencies has been taken.

Rajendra II Radar

Rajendra II Radar is also slewable passive phased array radar. By 2005, Rajendra II had participated in more than 15 flight trials at Balasore missile testing range. The flight trials have been spread over 4 missions in both group and autonomous mode. High altitude engagement, far boundary engagement, crossing and receding target engagement and multiple missions against multiple targets capabilities have been established.

Consistency in performance of radar in guiding missiles as close as 15m is established. During a mission, a Pilot less Target Aircraft (PTA) was neutralized while engaging crossing and receding target.

Rajendra radar is used for 3-D target detection, multi target tracking and multiple missile guidance under extreme hostile EW environment. A main phased array consisting of 4000 phase control modules (PCMs), and a command phased array consisting of 1000 PCMs have been built to achieve the multi-functionality. A powerful high-end computer computes phases for all the elements of the array. Rajendra controls the beam positioning sequence through beam requests for each track at adaptive data rates and performs multifunctional roles like search –confirm –track -interrogate targets, assign and lock on launchers, and launch/acquire/ track/guide missiles. The RDP supplies track data to remote group control centre. Rajendra features a Dual channel radar receiver and a C band transmitter, although the complete transmiting and receiving features and bands are unknown.

Rajendra Multisensor Tracking features 2-D battery surveillance radar (BSR) with 360 degree coverage and a larger detection range provides track data to the multifunction, slewable, 3-D phased array radar. The multisensor direction finder in Rajendra processes the track data from the phased array radar and the BSR to identify the targets reported by both the sensors and maintains a common track database. For those BSR tracks, which are not being reported by Rajendra though under its coverage, target acquisition is initiated with elevation search in the designated direction. The antenna is skewed in the direction of threat to acquire the targets, which are outside the covered air space.

The major functions of the radar are:
•Surveillance of the assigned volume of space
•Acquisition of aircraft targets either independently or handed over from group control centre and battery surveillance radar
•Tracking of targets
•Tracking of assigned targets and missiles during engagement
•Command guidance of missiles
•Integrated IFF functions

The AKASH Surface to Air Missile (SAM) system is guided by Rajendra radar. Rajendra radar features a “phase shifter” technology. Phase shifter when integrated in large numbers for electronic beam steering, allows Rajendra radar to simultaneously track multiple aircraft and also guide multiple missiles towards these targets. The phase shifter was designed and developed by Prof Bharati Bhat, a scientist from Centre for Applied Research in Electronics (CARE) of IIT, Delhi, and her team.


Dhanush test fired

BALASORE: India's indigenously developed surface-to-surface ballistic missile Dhanush was on Friday test-fired from a naval ship in the Bay of Bengal off Orissa coast.
The test launch was conducted from INS Subhadra , about 40 nautical miles from Chandipur-on-sea, at around 2.30 pm, sources said.

Dhanush , considered the naval version of surface-to-surface missile Prithvi, was being exclusively developed for the Indian Navy and has a striking range of 250 km to 350 km.

It can be deployed as an anti-ship weapon as well as for destroying land targets depending on the range. It can carry both conventional and nuclear weapons in its operational stage.

Friday's test launch, carried out by scientists of Defence Research and Development Organisation (DRDO), had been tracked from its take-off to impact point through an integrated network of sophisticated radars and electro-optic instruments for data analysis.

The 8.56 metre long missile had a launch weight of 4,600 kg and uses a single stage liquid propellant engine.

Dhanush was test-fired for the first time on April 11, 2000, from the integrated test range (ITR) at Chandipur-on-sea. However, it had failed at the blast-off stage due to technical snag in its software system.
The second test was carried out from INS Subhadra on September 21, 2001.

The two subsequent experiments were carried out on November 7, 2004 and December 28, 2005 from INS Subhadra and INS Rajput respectively.


Missile Defense: Lower Atmosphere Interceptors To Be Developed By DRDO
Dated 2/12/2006

Buoyed by a successful missile interception in higher atmospheric zone, defence scientists are now planning to shoot down incoming warheads, much closer to ground, with a new missile named Pad.

The country's top Missile Scientist Vijay Kumar Saraswat told a press conference today that "within the next three to four months the DRDO is planning to carry out another missile interception in the endo-atmospheric zone" -- a pattern used by the Americans in the development of their Patriot PAC-III anti-missile shield.

"We have demonstrated the technology to defend against incoming ballistic missile threat," he said, but added it would take another three to four years to develop for the country a full-fledged anti-missile theatre shield.

Saraswat's announcement comes in the midst of recent criticism of the DRDO which has been accused of allowing "heavy time and cost overruns" in critical projects.

He admitted that the Pad was still a technology demonstrator and said it would need another half-a-dozen tests to validate it as a missile shield.

The scientist said in any future indigenous missile shields, India would have to have a mix of exo-atmospheric and endo-atmospheric interception capabilities to match short reaction threats.

He ruled out that India might opt out of trying to acquire either the American or Israeli anti-missile system saying "we are only at the beginning and at this stage co-development or outright acquisition cannot be counted of."

Saraswat is the Chief Controller of the country's missile programme and project director of the air defence missiles, whose team successfully carried out India's first ever surface-to-surface missile interception in the exo-atmospheric zone on November 27.

DRDO decides to invite faculty from colleges for collaborative research

The Defence Research and Development Organisation (DRDO) will invite teaching faculty from science and engineering colleges for carrying out research in its laboratories in collaboration with DRDO scientists.

This is part of its efforts to partner educational institutions for promoting research and coming up with products that will enhance the nation's defence capability, S. Vathsal, Director (Extramural Research and Intellectual Property Rights), DRDO, New Delhi, said here on Friday.

He was talking to reporters at Arunai Engineering College, where he had come to participate in the National Conference on Simulation, Modelling and Optimisation. Dr. Vathsal said the Defence Ministry was planning to enhance allocation for research and development.

DRDO would invite academics aged between 25-40. It would provide the seed money. They would be required to prove their research findings through patents and publications within a year.

Collaborations

DRDO was already collaborating on 265 projects with 88 educational institutions and universities. Such collaboration, hitherto confined to government educational institutions, would be extended to private institutions in future.

Dr. Vathsal said the DRDO was trying to enhance the number of patents obtained by Indian scientists. India did not figure among the top 10 nations with respect to the number of patents. It had about 5,000 to 6,000 patents. Patents held by the U.S. ran into several lakhs.

High cost of patents

The small number could be attributed to the very high cost of applying for a patent. Now the Technology Information Forecasting and Assessment Council (TIFAC), Department of Science and Technology, had come forward to fund the efforts of universities, scientists and engineers in obtaining patents.

"We have about 10 to 15 success stories where the collaborative projects with universities have been useful in direct applications in the defence sector", he said, replying to a question on whether the collaborative projects had been useful to the country.

Dr. Vathsal said the country's technological development depended on forging a strong link among academic institutions, R&D laboratories and industry. Academic institutions should provide the manpower for research.

The labs would provide the facilities. And industry should manufacture the products developed.

"This link is very weak at present, and we are trying to strengthen it", he added.


DRDO develops anti-nuclear mask
Bangalore, May 19: In a significant development, the Defence Research and Development Organisation (DRDO) has indigenously developed state-of-the-art equipments to face any eventualities arising out of modern warfare like that of nuclear or chemical weapons.

The Chief Controller of Life Sciences Research and Human Resources, DRDO, Dr Selvamurthy said that the defence services have already begun the use of masks and modern equipments.

"DRDO has nine life science labs across the country and they have indigenously developed nuclear, biological and chemical defence masks, and other 35 products to face any threat arising out of chemical and nuclear wars. They have also developed bio warfare agents, field diagnostic kits to fight biological eventualities like that of typhoid, dengue, malaria, anthrax or any other viruses," he said.

The scientific arm of Indian Defence Services has also developed a de-contamination vehicle to sanitise air, ground and water.

"These labs have also developed chemical warfare detection system, portable chromatograph, to protect both civil and defence society. A de-contamination vehicle has also been developed to decontaminate air, ground and water," he said.


Kerala to have world-class missile facility soon
Wednesday June 27 2007 12:25 IST

T'PURAM : The state will soon have a worldclass missile development facility with the takeover of Kerala Hitech Industries Limited (Keltec) by BrahMos Aerospace.

Sources told this website’s newspaper that the takeover of Keltec by BrahMos was under the active consideration of Union Defence Ministry. Industry Department officials agreed that a formal agreement for take over of Keltec could be expected soon.

In May 2007, a Defence delegation from BrahMos visited Keltec to conduct spot study and analyse the potential of the company. The delegation members collected information and further directions are awaited from the Ministry of Defence.

A joint venture company with 50.5 percent stakes with the Indian Government and 49.5 percent shares by the Russian Government, BrahMos manufactures Supersonic Cruise Missiles with conventional warhead that can be launched from submarines, ships, aircraft or land. These missiles are unique due to its 2.8 Mach supersonic speed with much longer strike range than other missiles. BrahMos has evinced its interest in the take over of Keltec and to develop it into a world-class missile facility with system integration and testing. A supplier of high precision strategic defence and space equipment for the Defence Research and Development Organisation (DRDO) and ISRO, Keltec looks forward for its technological upgradation.

According to the State GO dated March 22, 2007, the takeover of Keltec would attract initial additional investments of about Rs 200 crore to the state. The advanced missile development facility will be the first Defence production unit in Kerala.

The facility in conjunction with ISRO will generate tax revenue to the state.


DRDO chief confirms submarine ballistic missile ready

Express News Service
Sunday, July 08, 2007

New Delhi, July 7: The country is set to complete its nuclear triad with DRDO indicating that it has completed development of a Submarine Launched Ballistic Missile (SLBM). While earlier DRDO refused to comment on the project, its chief M Natarajan on Saturday said a “special purpose missile” for the Navy has been launched.

Ministry sources said he was referring to the Sagarika or PJ 02 project SLBM. The two-stage missile, with a range of over 800 km, has been successfully tested thrice. This will give India the capability to launch nuclear weapons from land, air and under sea.

Sources said an award for developing a “special armament system for a strategic programme of national importance” given to a team led by S K Vasudeva is an indication that the project would shortly be made public.

The missile has been developed for deployment on the indigenous nuclear submarine code named Advanced Technology Vehicle. The submarine is scheduled for sea trials next year.

DRDO also said it was working on an advanced version of the Agni III to increase its range by 1,500 km. Nata- rajan said scientists working on the project have figured out a way of adding a third stage to the missile that will push up its range to 5000 km.

“It looks possible to extend the range in the same model. We may be able to fit in another phase to extend it to another 1,500 km,” Natarajan said. The Agni III missile will be ready for induction into strategic command by 2010.

<b>DRDO making 1000km subsonic cruise missile Nirbhay</b>

SUJAN DUTTA
New Delhi, July 19: Indian defence scientists have taken up a new cruise missile development programme. The missile named Nirbhay (The Fearless) is in the same class as the US’s Tomahawk and will have a range that is 300km longer than Pakistan’s Babur.

Nirbhay is India’s seventh missile development project after the Agni series, the Prithvi series, Brahmos (in a joint venture with Russia), Akash, Trishul and Nag. The last three were part of the Integrated Guided Missile Development Programme founded by A.P.J. Abdul Kalam.

Nirbhay is being developed alongside Astra, an air-to-air missile designed to hit targets beyond visual range.

A cruise missile can be guided to a target. A ballistic missile is fired at a pre-determined target. Nirbhay will carry onboard a terrain-identification system that will map its course and relay the information to its guidance and propulsion systems.

“Every modern military needs to have missile options. The requirement for Nirbhay was projected by all three armed forces to fill a gap in our missile programme,” Avinash Chander, the director of the Advanced Systems Laboratory, Hyderabad, who is in charge of the project, told The Telegraph in Delhi today.

Nirbhay will be a terrain-hugging missile capable of avoiding detection by ground-based radar. It would have a range of 1,000km.

“We have Brahmos, which is a supersonic cruise missile and the need was felt for a subsonic cruise missile that will be capable of being launched from multiple platforms in land, air and sea,” Chander said.

In the schedule drawn up for Nirbhay, a technology demonstrator is slotted for early 2009. Chander said the design for the system is complete and “hardware preparations are on”. He said Nirbhay would weigh around 1,000kg and travel at 0.7 mach (nearly 840kmph) and would be capable of delivering 24 different types of warheads.

The Pakistan's chinese made subsonic cruise missile Babur (also called Hatf VII) has ranges of 500 to 700km. The US’s Tomahawk has many versions, the latest of which has ranges in excess of 1,500km.

<b>DRDO Develops Stealthy Under Water Mines for Indian Navy</b>

The Naval Scientific Technological Laboratory (NSTL) here, a wing of Defence Research Development Organisation, has developed a deadly device called underwater mine which will do the job. Evolved by indigenous technology at the NSTL, the underwater mine will join the Indian arsenal shortly to bolster Indian Navy's weapon shop.

Testing and rating of the device has been completed successfully and the weapon and the project will be handed over to the Indian Navy. The device which will be planted underwater, can destroy enemy objects including sub-marines, war ships and even small boats which may come within a particular radius of the location of the device.

The NSTL has completed the requisite administrative formalities before the device is released officially. NSTL which has planned to hand over underwater mine in the first week of July put it off due to some technical reasons.

A senior official told this website's newspaper that their project has been completed successfully but declined to divulge the cost of the project. Normally, the cost of research and development of this type of weapons is no constraint, but NSTL executed the project within the stipulated budget, the official revealed.

This is the first of its kind device. It will add a feather to Indian Navy�s cap, particularly in view of future challenges it might encounter, a senior scientist claimed with pride.

With regard to the success of the underwater mine venture, the naval sources expressed their delight and said it would be a real push to the Indian Navy: We are also eagerly waiting for the day to induct the device into the Navy's arsenal.

<b>US expresses interest in India’s DRDO made Mine-Protected Vehicle</b>

New Delhi, Aug 02: The US defence department has evinced keen interest in an indigenous mine-protected vehicle that the Army is set to induct for anti-insurgency operations in Jammu and Kashmir.

The ‘Aditya’ vehicle which was developed by DRDO and will be inducted by the Army by November to provide increased protection to troops engaged in counter-terrorism operations.

The Army has projected a requirement for 1,400 such vehicles and given the green signal to induct 300.

Official sources said the US authorities had expressed interest in the vehicle mainly due to its ability to withstand an explosion of up to 10 tonnes of TNT, far beyond the capability of any similar vehicle.

But the Americans, who are eyeing these specialised vehicles apparently to cope with increased car bomb attacks in Iraq, will have to wait.

B P Bapu, joint general manager of the ordnance factory in Medak that produces the Aditya, said the Army had ordered a large number of vehicles and the unit could not aspire for any export orders now.

Bapu said the mine-protected vehicle was displayed during Army Chief Gen J J Singh`s recent visit to the central Indian garrison town of Mhow.

<b>BEL to export DRDO's anti-infiltration radar to Indonesia</b>
5 Aug, 2007, 1350 hrs IST, PTI

NEW DELHI: Striving for long to break into the lucrative arms export market, India has finally managed to get a toehold by bagging an order for sale of short-range battle field surveillance radar to Indonesia.

<b>The sale order is eventful as the Indian company, which won the order, was in strong competition with some of the world's leading radar and electronic warfare equipment manufacturers like American Raytheon and European consortium Thales.</b>

The contract for the sale of man-portable battery- powered surveillance and acquisition radar has been won by public sector blue chip company Bharat Electronic Limited (BEL) for which it will be a maiden test in export. The company recently won the coveted 'Navaratna' title and in the last fiscal reported a turn over of Rs 4,240 crore logging a profit of Rs 724.55 crore.

Though the successive NDA and UPA governments have year in and year out set ambitious arms export targets, these have repeatedly fallen short of the mark. In 2003-04, the NDA government had set up a weapon export target of a modest Rs 1,000 crore and even that was never reached.

And the reasons appear not too hard to locate as so far Indian arms companies, all of which are state-owned, have only been allowed to peddle old arms.

The companies were exporting only weapons systems which were on the verge of being phased out, like old Vijayanta tanks, light artillery guns and other systems, by the country's armed forces. "This is for the first time that India has managed to sell a world class product with superior features compared to similar products available from international manufacturers," a top BEL officer said.

The radars being sold are capable of detecting moving targets like foot-patrols, army and civil vehicles, tanks and artillery pieces. "These are ideal for checking illegal incursion on borders of all terrain".

BEL officials were not forthcoming on the number of radar systems being sold. But Defence Ministry sources said the initial order could be anything up to 100 systems. BEL has recently set up an extensive facility for manufacture of such radars as already it has a big contract for such systems from the Indian Army.

The man-packed battle field surveillance radar indigenously developed by DRDO are being used by army successfully in detecting and confronting infiltration across the Line of Control in Jammu and Kashmir in tandem with sensors and hand-held thermals imported from Israel.

"Supplies to India Army began in March 2005," the BEL official said adding the mobile radars can be carried in three man-packs for deployment to any location.

Radars are light weight, man-portable and can be quickly deployed. They can operate 24-hours a day under all weather conditions, officials said. Radars have low probability of interception, can track 50 targets at the same time, can also classify targets, based on audio doppler signature and have the provisions to network with other radar systems for wider area coverage.

The new systems, a force multiplier for security forces in their hunt for terrorists in tough tarrain, have the capability of picking up armed groups five km away and moving vehicles from a distance of eight km.

"There is a sharp demand for these systems in anti-infiltration operations," an army official said adding after Jammu and Kashmir the radar would be needed to be deployed on Indo-Bangladesh border in the Northeast.

"These can also be ideally used against naxalities," the official said.

<b>Weaponised version of DRDO's Dhruv makes maiden flight</b>

<img src='http://www.hindu.com/2007/08/17/images/2007081762311701.jpg' border='0' alt='user posted image' />
A MILESTONE: A weaponised Dhruv on its first flight in Bangalore on Thursday.

BANGALORE: Aviation major Hindustan Aeronautics Limited (HAL) is racing ahead with Dhruv, its Advanced Light Helicopter (ALH) project, the domestic market for which has crossed the 250 aircraft mark. The weaponised version of Dhruv made its maiden flight at the company’s Helicopter Division here on Thursday. So did the first ALH driven by a higher-powered Shakti engine, designed and developed jointly by HAL and Turbomeca.

The weaponised version, according to HAL Chairman Ashok Baweja, will be delivered to the armed forces in mid-2009. The whole of next year will be used for trials. The provisional certification was expected in January-February, he told presspersons here.

To meet the high altitude power requirements of the weaponised Dhruv projected by the Army and Air Force, HAL had to replace the earlier Dhruvs powered by the TM 333-2B2 Turbomeca engines. The Shakti engine develops about 30 per cent more power than the 2B2 engine. This translates to more than 150 per cent increase in the aircraft’s payload capability at high altitudes.

Although Thursday’s first flight of the weaponised Dhruv carried only dummy arms, the helicopter will eventually be fitted with “fire and forget” air-to-air missiles, 70 mm rockets that can be fired both in “direct” and “indirect” modes and 20 mm Turret guns which can be “slaved” to electro-optical system or the helmet pointing system.

The pilot will only need to merely look at the target for the gun to automatically point to the target.

In the near future, Dhruv will also be integrated with “fire and forget” anti-tank guided missiles.

International bids
With its joint-marketing partnership with Israel failing to take off, HAL will market the ALH on its own. HAL has already placed bids in Chile, Turkey and Bolivia, but wants to first meet the Indian demand completely and ensure support for service and maintenance, said Mr. Baweja.

HAL currently has an order book for 75 helicopters. The company is also likely to bag an order for 12 air ambulance versions of the helicopter.

Mr. Baweja said the tail rotor blade issue had been sorted out. “We are now meeting the military standards. The vibration levels are today less than or equal to the required standards.”
Simulation school

To address the training needs of the domestic helicopter market, HAL and the Canadian Aviation Electronics (CAE) will jointly launch a simulation school called Helicopter Academy to Train by Simulation of Flying (HATSOFF), in Bangalore. The US$ 52 million school, to be funded equally by HAL and CAE through a Shareholders Agreement, will be operationalised in September 2008.

<b>DRDO made Advanced Exercise Miness handed over to Indian Navy</b>

VISAKHAPATNAM: The Defence Research and Development Organisation’s Naval Science and Technological Laboratory (NSTL) here on Thursday handed over two advanced exercise mines (AEMs) to the Navy, marking an important day in the laboratory’s history.

Chief Controller (R and D) of DRDO A. Sivathanu Pillai handed over the service records of the AEMs to Flag Officer Commanding-in-Chief of the Eastern Naval Command Vice-Admiral Raman P. Suthan at a function. <b>NSTL completed the Rs.7.85-crore indigenous project well ahead of the December 31 deadline at a cost of only one-fifth or one-sixth of the cost of imported technology.</b>

While congratulating the scientists and support staff and industries, Dr. Pillai thanked the Navy for its support.

<b>NSTL, which had developed several mines and torpedoes, was working on a new thermal engine heavy weight ship-launched torpedo “Varunastra.”</b> The project was in the final stage and the new weapon would be inducted into the Navy by mid-2009.

Vice-Admiral Suthan said the Navy was short of exercise mines, which had a direct effect on training its personnel. The AEMs should help it to overcome this problem, he said. NSTL director V. Bhujanga Rao said this was a momentous occasion for the laboratory and the Navy’s support was crucial in developing the process-based advanced mines.

<b>DRDO begins work on Agni-IV missile</b>

Y. Mallikarjun

HYDERABAD: Even as Agni-III, the 3,500 km range ballistic missile, is getting operational, the Defence Research and Development Organisation (DRDO) has begun work on Agni-IV, a 5,000 km range missile, to provide “enough capability” for a credible deterrence to the country.

“Work on the 5,000 km range missile is on and the first trial is expected to take place in early 2009,” said V.K. Saraswat, Chief Controller, R&D (Missiles and Strategic Systems), DRDO.

New features

Talking to The Hindu here on Wednesday, he said Agni-IV would have many new features, including anti-ballistic counter measures and rocket motor systems with composite materials to improve the thrust-to-weight ratio. It would be equ ipped with stealth technology and be more accurate than those currently available in market with improved mobility and higher energy.

Maintaining that Agni-IV was not an Inter-Continental Ballistic Missile but a long range one, he said Agni-III and Agni-IV were the building blocks for missiles with longer reach.

Pointing out that all the major technologies for long range missiles had been realised following the successful flight test of Agni-III in April this year, he mentioned some of them as high-power booster, multi-stage vehicles, good re-entry know-how which could sustain aero-thermal loads at very high Mach numbers and a potent navigation system to maintain accuracy throughout the flight path.

Security requirement

Asked about the need for a 5,000 range missile, Dr. Saraswat said “when our threat perception is deeply analysed, we feel that ranges from 2,000 km to 5,000 km will give enough capability to have credible deterrence.”

Stating that long range missiles were designed on the basis of the country’s security requirement to counter existing or emerging threats, he said the need might arise for a 10,000 km missile in future.

He said Agni-III’s deployment was proceeding concurrently and only the system’s repeatability and reliability would be tested in future trials without major technological changes.

The DRDO has also started a technology development project for building a long endurance, long range cruise missile that will fly at high subsonic speeds. The advantage of subsonic cruise missiles was that they would enable delivery of payload at low cost. Because they fly at low altitude such missiles would be difficult to be detected by enemy radars.

<b>DRDO made Supersonic missiles to be inducted by 2009 in Indian Armed Forces</b>

Friday August 17 2007 11:31 IST

VISAKHAPATNAM: The Indian Armed Forces would have Land Attack Supersonic Missiles (LASM) inducted in their arsenal by 2009.

These missiles, possessed by a few other countries in the world, would enhance the combat capabilities of the Indian Army, Navy and Air Force, said DRDO Chief Controller (R&D) A Sivathanu Pillai.

Pillai told newsmen on Thursday that the LASM have already been tested for the Army and Navy and they are pending integration with the Air Force.The process of developing Underwater Autonomous Vehicles, which would be camouflaged, would be completed by 2008-end.

Pillai said India’s public and private sector units must gear up to meet the requirements of the country’s Defence weaponry. Out of the $30 billion Defence spending in the next five years, equipment valued at $10 billion is planned for manufacture indigenously.

The small players in the field of Defence production could form into a consortium with the major industries for both designing and manufacturing.

This would be providing an integrated platform for undertaking Defence contracts and facilitate their speedy execution.

In addition to NSTL, the Naval Physical and Oceanographic Laboratory, Kochi has developed underwater sensors called ‘Sonars’, which help in identifying the targets.

Besides, the National Materials Research Organisation developed a technique of painting and attending to maintenance works on Naval platforms at sea.

<b> DRDO gives Indian Army a new weapon to fight terror- Portable laser weapons</b>
17 Aug 2007, 1210 hrs IST,PTI

JAMMU: Soldiers engaged in counter-terrorist operations in Jammu and Kashmir and the northeast will soon have a new weapon to help them take on militants -- portable non-lethal laser dazzlers that can stun and blind their opponents.

<b>"Two versions of the portable non-lethal dazzlers (PNLD), including a hand-held laser dazzler, are set to be inducted into the Indian armed forces for use in counter-insurgency operations. </b>

This will make the 21st century soldier a technology-driven jawan," a top defence source told a news agency.

<b>The laser dazzlers, which can be mounted on existing weapons used by the soldiers, were tested in Kashmir in October last year and will be inducted into the army possibly by next year, sources said. </b>

They could be used against militants operating in the hinterland of Kashmir and against those infiltrating into the state across the Line of Control (LoC).

<b>The Defence Research and Development Organisation's Laser Science and Technology Centre (LASTEC) in Delhi has developed two variants of the PNLD suitable for counter-terrorist operations.

The hand-held and weapon-mounted versions of the PNLD have a maximum range of 50 meters and 500 meters respectively, the sources said.</b>

Both variants are completely non-lethal directed-energy weapons employing intense visible light and produce randomly a flickering green laser output that is sufficient to cause temporary blindness or disorientation.

The dazzlers also have an in-built safety interlock to prevent misuse and the weapons do not cause permanent blindness, the sources said.




<b>Indian Army to induct laser weapons</b>

Anil Bhat in Jammu | August 17, 2007 12:19 IST

Soldiers engaged in counter-insurgency operations in Jammu and Kashmir and the north-east will soon have a new weapon to help them take on militants -- portable non-lethal laser dazzlers that can stun and blind their opponents.

"Two versions of the portable non-lethal dazzlers, including a hand-held laser dazzler, are set to be inducted into the Indian armed forces for use in counter-insurgency operations. This will make the 21st century soldier a technology-driven jawan," a top defence source told PTI.

The laser dazzlers, which can be mounted on existing weapons used by the soldiers, were tested in Kashmir in October 2006 and will be inducted into the army possibly by 2008, sources said.

They could be used against militants operating in the hinterland of Kashmir and against those infiltrating into the state across the Line of Control.

The Defence Research and Development Organisation's Laser Science and Technology Centre in Delhi has developed two variants of the PNLD suitable for counter-insurgency operations.

The hand-held and weapon-mounted versions of the PNLD have a maximum range of 50 meters and 500 meters respectively, the sources said.

Both variants are completely non-lethal directed-energy weapons employing intense visible light and produce randomly a flickering green laser output that is sufficient to cause temporary blindness or disorientation.

The dazzlers also have an in-built safety interlock to prevent misuse and the weapons do not cause permanent blindness, the sources said.

The dazzlers also have an integrated low power red laser beam for aiming in twilight and dark conditions.

The weapon-mounted dazzler has an integrate daylight sight too.

After trials of the dazzlers in the north-east and Kashmir, a memorandum of understanding was signed for manufacturing the systems for the army, the sources said.

Under the MoU signed by the Defence Research Development Organisation with SDS Electronics Pvt Ltd of Panchkula, the transfer of technology for the two versions of the PNLD was completed in November 2006, the sources said.

<b>The laser dazzlers use "diode pumped solid state" lasers with a wavelength of 532 nm and weigh 850 g.</b>

Blinding weapons are banned by the 1995 United Nations Protocol on Blinding Laser Weapons.

As these dazzlers do not cause permanent blindness, they skirt this regulation, the sources said.

On 18 May 2006, the US military announced it would issue dazzling lasers designed to be attached to M-4 rifles to troops in Iraq.

This weapon is intended to provide a non-lethal way to stop drivers who fail to stop at checkpoints manned by US soldiers.

The US forces also used the Saber 203 dazzlers in Somalia in 1995 during Operation United Shield.

DRDO's FRL improves army life at Siachen
<!--QuoteBegin-->QUOTE<!--QuoteEBegin-->Wednesday, August 22, 2007 (Leh)

The guns may have fallen silent on Siachen, the world's highest battlefield, in the past four years but the icy weather and inaccessible location remains a constant enemy and an enduring challenge for the Indian army.

But thanks to a combined effort of the Defence Research and Development Organisation (DRDO) and the army, there is a constant effort to improve the soldiers' life in high altitude areas.

Located at Leh, the DRDO's field research laboratory has devised ways to make life comfortable for soldiers' deployed in these difficult conditions.

One of the oldest labs in the country, the Field Research Laboratory has developed techniques that allow a variety of non-indigenous crops to grow in the barren landscape of Ladakh.

It allows soldiers to get fresh vegetables locally instead of depending on supplies from the plains of Punjab. It also helps the local economy.

''We first experiment new techniques on our farms and then pass the technique onto the local farmers. This has helped us to reduce the length of the supply chain,'' said Dr Zaman, Director, FRL, Leh.

But agriculture is not the only field that the FRL deals in. After the Kargil War, it found the mules were not able to withstand the harsh weather. So now it has developed a new breed.

The FRL also plays a major part in Operation Clean and Green Siachen.

Synergy between the FRL and the army deployed in Ladakh has ensured that there is a constant improvement in the life of the soldiers deployed in these adverse conditions.<!--QuoteEnd--><!--QuoteEEnd-->

Unmanned underwater vehicles being developed by DRDO
<!--QuoteBegin-->QUOTE<!--QuoteEBegin-->Coimbatore, PTI:

The Naval Science Laboratory at Visakhapatnam has developed the technology and is in the process of making prototype of 'unmanned underwater vehicle',(UUV), Dr A Sivathunu Pillai, Chief Controller of Research and Development, DRDO, said.

The Naval Science Laboratory at Visakhapatnam is developing 'unmanned underwater vehicles,' (UUV) for carrying out surveillance in the sea, a top DRDO official said today.

With India moving fast to become self-reliant in underwater technology," the laboratory has developed the technology and is in the process of making prototype of UUV," Dr A Sivathunu Pillai, Chief Controller of Research and Development, DRDO, told reporters here.

The vehicles would be of much use for the Indian Navy for surveillance under the sea and also to trace and send signals about the presence of any submarine, ship and other objects deployed by the enemy, Pillai said.

Similarly, the Indian Navy has accepted the newly developed Advanced Experimental Torpedo 'TAL,' to hit targets under the sea, Pillai said, adding Hyderabad-based Bharat Dynamics Ltd, would commence its production soon.

TAL is capable of locating the underwater target with its homing device, hit and destroy it, he said. With DRDO already delivering Advanced Underwater Mines to the Navy, India is reaching a stage of self-reliance in underwater technology, Pillai said.<!--QuoteEnd--><!--QuoteEEnd-->

DRDO August 2007 Newsletter-Techfocus Special on Dhanush-----PDF File
<!--QuoteBegin-->QUOTE<!--QuoteEBegin-->DHANUSH

Missiles are a must for any modern military outfit. They act as a force multiplier as is evident from the recently fought wars in the South Asia and the Gulf. Most of the missiles technologies come under the purview of sanctions imposed by the developed countries.

To provide thrust and to promote self-reliance in the areas of missile systems, an Integrated Guided Missile Development Programme was launched by the DRDO in 1983 to develop a family of strategic and tactical guided missiles.

Since then DRDO has achieved a unique degree of success leading to the development of a number of missile systems like Prithvi (a short-range ballistic missile), Agni (medium-range missile), Akash and Trishul (short-range surface-to-air missiles), and Nag (third-generation antitank guided missile). Prithvi has now been inducted into the Services, while the serial production of Agni has started.


MESSAGE

IGMDP programme sanctioned in 1983 provided for a major thrust in the design and development of indigenous technologies and capabilities in the field of missiles. It was both a learning curve and a challenge.

The technologies, expertise and capabilities built have provided a platform enabling the country to take a quantum leap into development of futuristic world-class missiles. Agni and its variants have been successfully inducted and handed over to the Army. Today Prithvi and its variants find a place of pride in the inventory of Indian Army, Indian Air Force, and Indian Navy.

Project Dhanush, a Naval variant of Prithvi missile on ship, and its deployment from a moving platform, was a major technological challenge both in terms of hardware and software. It enabled demonstration of the indigenous capability for the stabilisation of the missile launcher and first vertical launch of Prithvi variant missile from an OPV class of ship.

Successful enhancement of range, development of GPS INS-based close-loop guidance system and conduct of ‘Acceptance Test Firing’ independently by the naval teams have boosted the users confidence in the indigenous systems/technologies.

Successful trials of the BrahMos missile, both naval and land version, and their induction into Indian Navy and Indian Army has been another landmark in the development and demonstration of the indigenous capability.

The successes achieved in these fields are attributable to the synergy developed between the DRDO, Services, and academic institutions; PSUs like Bharat Dynamics Limited, Hindustan Aeronautics Limited; and private industry. {PPP-Public-Private Partnership}

Today the country has a demonstrated capability for design, development and manufacture of all types of missiles.

I am glad to note that DESIDOC is bringing out a Special Issue of Technology Focus to highlight the success achieved by Project Dhanush. This should motivate one and all to come together, overcome the technological challenges and reduce the dependence on imported systems/technologies.
Dr VK Saraswat
Distinguished Scientist & Chief Controller R&D (MSS)


After successfully developing these missiles, DRDO has also developed indigenously Dhanush missile (a naval variant of Prithvi) and a supersonic
cruise missile, BrahMos, in collaboration with Russian entity Mashinostroyeniye.Both the missiles are ready for induction into the Services after successful trials at sea. This issue of Technology Focus is highlighting the salient features and achievements of Project Dhanush.

Project Dhanush was sanctioned by the Indian Navy to integrate and demonstrate the feasibility of launching variant of Prithvi from a ship.

The translation from the technology demonstrator to weaponisation configuration , and induction of the Dhanush weapon system has been completed with the successful 'Acceptance Test Firing' conducted by the user, and after achieving all the planned mission objectives.

The salient features and achievements of Project Dhanush required development and realiasation of a number of systems. Some of these are given below:

Realisation of Ship-based Systems

Following ship-based systems have been developed:

Launcher Stabilisation System (LSS) including electronics and hydraulics for stabilisation of a five-ton weight class Prithvi missile within 90±1” , in disturbance of ±10” of roll, and ±5” in pitch (sea state 4) on board ship, and deployment of a vertically stabilised Prithvi variant from ship.

Ship Motion Simulator with capability to generate roll of ±30 and pitch of ±15 for testing/evaluation of the LSS on shore. This was subsequently upgraded and converted into a LSS for the second ship.

Transporter Erector Trolley (TET) for transfer of Prithvi variant from the safe storage (SS) container and its integration on the LSS.

Object Transfer Trolley for handling of SS container (14 ton with the missile) on board the ship.

SS Container for safe storage of the Dhanush during transportation to and fro from the depot and for stowing on board ship.

Integrated Electronics System consisting of
*Power supply and distribution units to ensure availability of clean and regulated power supply at all the times for all the elements of the Dhanush weapon system.
*State-of-the-art Dhanush fire control system based on real-time operating virtual machine environment (VME)-based open architecture system for the auto launch of Dhanush with provision for future upgradation.
*Object handling system for semi-automatic, safe and fast integration of the Dhanush with the LSS.
*LSS controller for stabilisation of the LSS to the required accuracy in sea state 4 conditions. This has enabled deployment of the Dhanush missile in sea state up to 3.

Modification of the Ships
Naval ships have been modified for integration of the Dhanush weapon system and safe operation of the ship-based systems (weight approximately 40 ton).

Software
Following design, development and modification in the software were carried out for:-

Transfer alignment based on Kalman filter technique for alignment of inertial measurement unit (IMU) with the master inertial navigation system (INS) SIGMA 40 to define the azimuth for the missile trajectory and control and guidance.

Global positioning system (GPS)-INS fused navigation to reduce the cross-range error/cross-range error probability (CEP) at the impact point. The technology has completely eliminated the proportional dependence of CEP to range.

Launch point prediction software for prediction of the launch point on a moving platform.

Existing Cacoon software has been modified to enable deployment of missiles from any latitude and longitude.

Command control software to prevent unauthorised launch.

Integration of thrust vector control (TVC) backup in the analog-to-digital conversion (ADC) phase to augment the control effectiveness for extended range missiles based on 'dynamic sharing logic'.

Mission software.

Modification of the Airframe Sections

Modification of the airframe sections has been done to increase the range of Dhanush beyond 250 km by increasing the tank length and effective surface area of the control surfaces, and by augmenting and strengthening the control scheme/algorithm using the latest control techniques.

Secure C3 Network
A command, control, communication network has been implemented for reliable, assured and safe communication among all authorities.

Ground Systems
Fourteen types of ground systems have been realised for utilisation during preparation of Dhanush missile at depot. These include three special ground systems—MOSAIC D, missile carrier vehicle, and 40 T crane—especially developed for Dhanush missile system.

Composite Helo Deck
With the integration of the Dhanush weapon system, the flexibility of the Dhanush-capable ship to operate the helicopters was compromised. To restore this capability, DRDO took on the task of realising and integrating a helo deck made from lightweight composite materials.

DRDO has now developed a helo deck made of vinyl ester and E glass fabric on board such ships. With this, the Naval Commanders have the flexibility to operate the Dhanush class off-shore patrol vessles (OPV) in either Dhanush or helo role.

The successful translation of the technology demonstrator project to the final goal of weaponisation demonstrates the unique synergy created between the Indian Navy, DRDO, PSUs (BDL, HAL, etc.), and private industries (M/s L&T Mumbai, SEC Industries Private Ltd., VEM Technologies, etc.) to realise the mission objective for design, development and induction of indigenous technologies for the Defence forces.

Dhanush weapon system has continuously evolved with technology upgrades during the translation from technology demon-strator to the inducted weapon system held in the inventory of the users.

The range of the Dhanush has been increased beyond 250 km, the Flight Control System has been changed/upgraded from 80286 MB II technology to open architecture VME-based real-time operating system, and user's feedback and inputs have been incorporated to simplify the ship-based operations in the area of man-machine interface and graphic user interface.

The following technologies have been realised/developed in-house during the execution of this project:
a. Realisation of extended-range class of ship-launched Dhanush missile.
b. Stabilisation system for stabilisation of missiles/radar/ guns/rockets weighing up to 5 ton.
c. Vx works-based VME operating system for Fire Control Systems of missiles/guns/rockets.
d. Linear motion rail technology for safe and reliable operations and handling of very heavy systems/objects in the presence of constant and unpredictable disturbances (roll and pitch motions).
e. Secure command control communication network.


Portable Carbogen Breathing Apparatus For Protection Against Noise-Induced Hearing Loss

Exposure to noise is well known to cause damage to the auditory system.Today, noise-induced hearing loss (NIHL) is a major and increasing problem in the industrialised countries, stemming both from the workplace and from leisure activities. The degree of hearing impairment depends on the intensity of the noise and the duration of exposure.

Experiments to study the mechanism of action of noise have established that exposure to noise initially causes temporary loss of hearing sensitivity, commonly known as temporary threshold shift (TTS).

If this loss is not recovered during rest pauses, it slowly turns into permanent hearing impairment referred to as noise-induced permanent threshold shift (NIPTS). Intense acoustic stimulation has been reported to produce discernible change in blood supply and oxygen tension of hair cells.

Thus, TTS produced by exposure to noise may be due to increased oxygen
consumption by hair cells coupled with depletion of blood supply caused due to vasoconstriction.

Therefore, any system that could counteract these effects is considered suitable to mitigate the degree of hearing loss. Carbogen, a gas mixture of 95 per cent Oxygen and 5 per cent Carbon dioxide, is a well-known powerful vasodilator of the cerebral capillary beds.

Its potential has been utilised by DRDO to counteract the vasoconstrictive effect of noise. During the laboratory studies, it was observed that administration of Carbogen even for short duration of 5 min before and after exposure to occupational noise provided dual benefit by reducing the magnitude of TTS development and accelerating the recovery process for normalisation of hearing status.

The equipment used earlier to administer Carbogen was bulky and cumbersome to handle and use. DRDO has designed a mobile Carbogen Breathing Assembly to deliver Carbogen for a period of 5 min before and after exposure to occupational noise in order to minimise and mitigate the adverse effects of noise on the auditory system of a human being.

The assembly is trolley-mounted for easy manoeuverability and comprises a gas cylinder, regulator, and humidifier and breathing masks in an aesthetically appealing module.

This mobile apparatus provides facilities for normal breathing in sitting and standing positions. The system finds application as a protective device for the conservation of hearing in workers occupationally exposed to intense noise for prolonged period such as the engine room of ships, naval dockyards, Indian Air Force, Ordinance Factories, traffic police personnel, and industries, etc.

The integrated system is portable, compact, and simple to use. The functional aspects of the prototype has been successfully evaluated in the laboratory set up as well as at Defence establishments (Indian Navy, Air Force and Army Workshops) where the personnel have to operate in an intense noise environment.

The system has been hailed as being effective, safe and user-friendly and one that supports the application of Carbogen as an effective prophylactic against NIHL.


The basic design of the system incorporates the carbogen cylinder coupled with flow control valve and timer. A nebuliser, housed in the body of the equipment, humidifies the gas before inspiration.

The system design has catered for reduced floor space requirement, weight and cost considerations. Design for fabrication of commercial prototypes of Carbogen Delivery System has been awarded to two vendors (M/s Vijay Sabre Safety Ltd, Mumbai, and M/s S.B. Equipment, New Delhi, and are likely to be available in the market soon.

A multi-user Kiosk workstation has also been developed to facilitate the administration of Carbogen to 10 individuals at a time.

Following the successful trials conducted by the Indian Navy on the efficacy of breathing Carbogen in ameliorating NIHL, the Indian Navy has communicated its desire to acquire 12 Carbogen breathing assemblies towards the first phase of induction in the Navy. DGAFMS has approved the installment of the system in nine medical units under different Commands.

Indian Navy has accepted advanced torpedoes designed by DRDO
<!--QuoteBegin-->QUOTE<!--QuoteEBegin-->COIMBATORE: The advanced experimental torpedo designed by Defence Research and Development Organsiation (DRDO) has been accepted by the Navy.

Its production has been taken up by Bharat Dynamics Limited (BDL) of Hyderabad, A. Sivathanu Pillai, Chief Controller of DRDO and Chief Executive Officer and Managing Director of BrahMos Aerospace said here on Thursday.

Dr. Pillai told reporters that the advanced light weight torpedo would be used as an underwater weapon by the Navy.

<b>Self-reliance</b>

With this breakthrough the DRDO was reaching a stage of self-reliance in under water applications. It was now looking at heavy weight torpedoes, Dr. Pillai said.

“Work on unmanned vehicles in underwater is under way and is in the prototype stages at the Naval Science and Technology Laboratory at Vishakhapatnam. The vehicle will initially do surveillance work. Later it might be considered for civilian uses too,” he added.

He said most of the naval materials had been indigenised.

DRDO was also in the process of developing a fuel cell that would have tremendous civilian applications.

It could be considered as an alternative to propel cars, he said.<!--QuoteEnd--><!--QuoteEEnd-->

<b>Indian submarines to be armed with DRDO's BrahMos missiles</b>
<!--QuoteBegin-->QUOTE<!--QuoteEBegin-->Zhukovsky (Russia), Aug 24: Indian Navy will induct DRDO 's submarine-launched BrahMos cruise missiles and preparations are underway for their trial, an official said here.

Spokesman of the Indo-Russian joint venture BrahMos aerospace, Alexander Maksichev said that it was not yet decided which of the Indian naval submarines will be armed with the deadly cruise missiles.

"India is mostly building French Scorpene class submarines. But soon the Indian navy will have to decide about additional submarines.

"It is not known yet which submarines, but what is certain is that they will be fitted with BrahMos missiles," Maksichev said speaking on the sidelines of ongoing international aerospace show Maks-2007 here.

Preparations are underway for their trial, the official said.

BrahMos aerospace has its own stall at the aerospace show and is displaying models of ship, land, air versions of the cruise missile with the speed twice that of sound, amid growing interest among potential buyers.

Under the joint venture deal, India and Russia have agreed to jointly develop, produce and internationally market the BrahMos cruise missiles to "mutually identified friendly nations".

According to experts BrahMos with a range of 200 km, developed on the basis of Russian Npomash`s `Yakhont` cruise missile will remain a unique missile for more than a decade and has a huge market.

However, some of the countries initially identified as `friendly` could undergo review by the russian general staff, according to the local defence ministry sources.<!--QuoteEnd--><!--QuoteEEnd-->

<b>DRDO to foray into export of military hardware </b>
<!--QuoteBegin-->QUOTE<!--QuoteEBegin-->Aug 30 2007

After catering to the requirements of the Indian armed forces for decades, the Defence Research and Development Organisation (DRDO) is now eyeing export of military hardware taking advantage of lower production costs at home.

DRDO sees export potential for certain types of rifles, rockets, and radars, while it had also secured orders for delivery of BrahMos cruise missle developed by an Indo-Russian joint venture, its Chief Controller (R&D) Dr W Selvamurthy, told PTI here.

While DRDO's mandate continues to be to meet the requirements of India's defence forces, the research firm has found that the technologies, products and systems developed in the process have overseas market.

"The cost of R&D and production is less in the country. Our prices are very competitive in the international market. We may be able to export certain systems", Selvamurthy said.

DRDO would target friendly neighbouring countries as well as third world nations for exports; "other countries" have evinced interest to buy BrahMos missiles.

"But we will be selective in giving it (things developed by DRDO) to other countries. We cannot give it to those who are not friendly to India", the DRDO official said.

According to him, a Mumbai-based firm has sought permission to export respiratory masks, the technology of which was transferred to it by DRDO.<!--QuoteEnd--><!--QuoteEEnd-->
