    Defence Minister Hands Over Indigenous DRDO Naval Systems

    The Minister of Defence, Finance and Corporate Affairs Shri Arun Jaitley handed over three Naval Systems indigenously developedby Defence Research and Development Organisation (DRDO) to the Chief of the Naval Staff, Admiral Sunil Lanba here today. The Minister also released two other products developed by DRDO namelyIP-based Secure Phone and the Gallium Nitride Technology. Speaking on the occasion Shri Jaitley remarked that DRDO is becoming an important instrument for self-reliance of the nation. He stated that some of the best innovations have come from the pool of scientists of DRDO. The Defence Minister also said that great societies and nations are made through people working on important tasks in anonymity, like the DRDO scientists who were honoured today. Shri Jaitley also said that in the modern world, societies that invent and innovate will make faster progress.

    The Minister gave away the annual DRDO awards in various categories during the function. Apart from the scientists and teams who won awards in various vistas of technological excellence, the Advanced Systems Laboratory, Hyderabad and the Microwave Tube Research & Development Centre, Bangalore won the coveted Silicon Trophy and Titanium Trophy respectively.

    The Naval Systems handed over to the Indian Navy are USHUS-II Submarine Sonar, Directing Gear for Hull Mounted Sonar Array, and RLG based Inertial Navigation System for Ship Applications (INS-SA). The export potential of DRDO technologies also received due recognition during the function, with the announcement of the bagging of export order for DRDO-developed torpedo to Myanmar.

    Speaking on the occasion Dr. Subhash Bhamre, Minister of State for Defence said DRDO is playing an important role in self-reliance of Defence Forces and the export potential of the Organisation is finding a place in the global Defence market. He congratulated all the awardees and their families.

    Chairman, DRDO and Secretary, Department of Defence (R&D)Dr. S Christopher in his address said the Defence Acquisition Council cleared order value of DRDO products has gone uptoRs. 2.56 lakh crore out of which about Rs. 1 lakh crore was in the last two years alone.

    Sonars are the eyes and ears of a submarine under water. DRDO has developed the State-of-the-Art submarine sonar suite, USHUS-II, a highly evolved compendium of multiple sensors. The constituent sonars in the suite include passive sonar, active sonar, intercept sonar, obstacle avoidance sonar and underwater telephony.

    Directing Gear is an electro-mechanical system that supports the transducer array of hull-mounted ship sonar systems and rotates it at a controlled speed for in-situ acoustic calibration at Harbour and Sea.

    The Inertial Navigation System, based on indigenous Ring Laser Gyroscopes, provides vital information on the ship's position coordinates and heading for steering it to its destination accurately. It features high speed processor, multi-constellation Sat Nav receiver, ship specific interfaces and innovative algorithms.

    With the emergence of Gallium Nitride as a state-of-the-art material for MMIC applications, DRDO has established this futuristic technology, which will substantially help in the development of next generation radars, seekers and communication systems, for application in Light Combat Aircraft.

    The Secure IP Phone incorporates an indigenous encryption algorithm on a trustworthy hardware platform to provide a high level of secrecy to voice and data, for communication of strategic and tactical plans of the Armed Forces.

    The function was also attended by senior functionaries of the Ministry of Defence, Indian Navy, DRDO and industry partners.

    IISc to get Rs 3,000-crore foundry to produce ‘wonder’ nano material
    The foundry is proposed to be developed around an existing facility for producing gallium nitride transistors on silicon wafers, at the IISc’s Centre for Nano Science and Engineering (CeNSE), under the leadership of associate professor Srinivasan Raghavan.

    The Indian Institute of Science (IISc) has received initial approvals from the government to set up a Rs 3,000-crore foundry to produce a “wonder” nano material, gallium nitride, that is emerging as one of the most efficient semiconductors for next-generation strategic technologies, including radars and communication systems.

    The foundry is proposed to be developed around an existing facility for producing gallium nitride transistors on silicon wafers, at the IISc’s Centre for Nano Science and Engineering (CeNSE), under the leadership of associate professor Srinivasan Raghavan.

    The proposal is currently at the highest level of the government. It needs about Rs 3,000 crore and is seen as a strategic-sector investment,” Prof S A Shivashankar of the CeNSE said.

    The nano material Gallium Nitride, or GaN, is a superior alternative to silica-based semiconductors and is expected to generate revenues in the range of $700 million by 2020, from the current range of $300 million, according to experts in the field.

    The proposal to set up a foundry at the IISc for producing GaN is a good development. Gallium nitride technology will substantially help in the development of next-generation radars, seekers and communication systems, and will be useful in systems like Light Combat Aircraft,” said R K Sharma, the director of the DRDO’s (Defence Research and Development Organisation) Solid State Physics Lab.

    The CeNSE facility at the IISc, which was inaugurated in 2015 by Prime Minister Narendra Modi, is attempting to create an ecosystem of GaN electronics, including materials, devices and systems. GaN-based transistors from the CeNSE are already being sold to researchers in the country. The creation of a commercial GaN foundry would service industry demand for the emerging technology.

    “What we need for strategic purposes is efficient energy consumption systems, and gallium nitride conductors are the answer. Unmanned vehicles, for example, which are the future of security systems, are dependent on energy efficiency,” Director Sharma said, adding that with countries like China investing in a very strategic manner in semi-conductor systems, India also needs to do so.

    Among the areas where GaN semi-conductors can be used are phased array radars for electronic warfare, like AESA radars that are fitted on ultra-modern fighter jets.

    The foundation for the development of GaN technologies was laid by the 2014 Nobel Physics Prize-winning work on blue Lighting Emitting Diodes using GaN, by Japanese-origin scientists Isamu Akasaki, Hiroshi Amano and Shuji Nakamura. The techonologies have also been used in blue ray information storage systems and are being utilised increasingly now in high-power and high-speed electronics.

    GaN is described as a wide-gap semiconductor with unique electronic properties. It is tough and can operate at high temperatures at high switching speeds with power flows much superior to silica.

    In every device, be it a laptop, an AC, or an automobile, there are electronic circuits that have to handle very high power and voltages. It is these circuits that constitute the field of power electronics,” Prof Srinivasan Raghavan says in a section on GaN at the CeNSE website.

    The worldwide power electronics device market is $36 billion. As power consumption goes up, the requirement for power electronics will go up. So when you start working on GaN-based materials, you are looking at potential impact on a much larger power electronics market. What we have set up here in the IISc is a GaN platform where many of these things can mushroom,” he states.

    India is Advancing its Radar Technology Capabilities
    Sep 5, 2017
    _____________________________________

    A new first-of-its-kind radar test facility has been set up in India. BEL (Bharat Electronics Limited) has set up a Near Field Antenna Test Range (NFTR) near Bangalore to calibrate and test radars with AESA (Active Electronically Steerable Array) based antenna arrays.
    A BEL statement said it is a critical infrastructure for calibration and testing of radars and communication antennas.
    With most future weapons platforms including aircraft and ships coming with AESA radars, this facility is expected to play an important role in absorbing foreign technology as well as the development of an indigenous system for AESA radars.

    The new range will enable the calibration of advanced radars India purchases from Israel’s Elta, IAI subsidiary. Such radars could possibly be manufactured in India in collaboration with IAI and Indian companies.

    According to defenseworld.net, the new facility is the third such in BEL and the only one in the Defence industry in India. This facility will, in addition to the AESA radars, help to calibrate antennas for major surface to air missile projects such as QRSAM, MRSAM and LRSAM.
    The Electro Magnetic Compatibility (EMC) facility is the first of its kind in India having Anechoic Chamber of size 11m x 21m x 30m and can conduct testing of Systems/Platforms weighing up to 70 Tonnes.

    EMC tests for strategic Defence systems like Battle Tanks, Communication vehicles, Radar systems and Airborne systems including Nuclear Electro Magnetic Pulse (NEMP) and High Altitude Electro Magnetic Pulse (HEMP) testing.

    It can be used to carry out system level EMC testing for many projects such as AKASH missile, LRSAM, Weapon Locating Radar and Battlefield Management System. The facility will also be open for use to other Indian Defence companies.
    The facility was set up at a cost of Rs. 30 crore (US$ 4.7 million).

    Apparently, @DRDO_India's LRDE is going to hire an executive jet being brought in by a private company to serve as a flying test bed for the Uttam AESA fighter radar. Structural modifications will be made to the executive jet, obviously.

    Uttam AESA Update:

    Ketan Gandhi: Sir any update on Project Uttam?

    M.V. Reddy: Project Uttam LRDE has completed the development part of it and only the aircraft integration
    part is left and that they are working out with ADA and once it is proved and then probably we
    will get orders. We are in the fray and it may take some more time for us to get the production
    quantity so the discussions are going on with, the DRDO is discussing with users so we are yet to
    finalize the quantity and all sort of a thing.

    Ketan Gandhi: Sir user trial is completed for Uttam or still under process?

    M.V. Reddy: Not completed in fully.

    Ketan Gandhi: So we are not sure whether it will be as soon as it is complete then only we will come to know
    that whether it is we are getting that order or not?

    M.V. Reddy: Yes I think, they are confident that it will be completed soon so we are hoping that this will be
    completed in next year so I think that is a model way we have followed.

    Ketan Gandhi: So after the initial quantity it might be if it is a stressful then we might see Project Uttam to be
    fitted in the Tejas?

    M.V. Reddy: Yes.

    Ketan Gandhi: Thank you.

    Arjun Mark-2 tank set to see light of day

    Design of Tejas’ next version almost done, indicates DRDO Chairman

    In an important move, the ‘Made in India’ Arjun Mark-2 tank project is set to see the light of the day.

    Chairman of the Defence Research and Development Organisation (DRDO) Dr S Christopher in an interview to The Tribune said, “We have had a meeting with the Vice-Chief of the Indian Army where it was agreed on accepting Mark-2. Modalities are being worked out”. Once done, the acceptance of necessity (AON) for 118 will be revived, he added.

    The AON is decided by the Defence Acquisition Council headed by the Defence Minister. A total of 93 modifications have been done on the first version of Arjun — 124 were inducted — in 2010-2011.

    On being asked if the Army was okay with the weight of the tank, the DRDO boss said: “The weight (the tank is almost 58 tonnes) has been accepted; that is a major change”. Most modern European tanks are of the same weight, and tank-transporters (specialised trucks) for Arjun are available.

    The DRDO has promised to set up a system to maintain the Arjun Mark-2 within India. It will be an annual maintenance contract with the Bharat Earth Movers Limited (BEML) as a possible agency, Dr Christopher said. On the trials, he said, “These have done 4,000 kms of run, the upgrades will be tested.”

    On artillery guns, Dr Christopher said the Advanced Towed Artillery Gun Systems (ATAGS), of which the Army has agreed to accept 40 pieces to start with, will get a more powerful engine to enable rapid movement. The guns designed by DRDO have been made by two private companies under the transfer of technology.

    The DRDO is keen to get a slice of the 1,580 towed guns the Army is looking to buy. “Both companies (Tata Power SED and Bharat Forge) are gearing up produce more. We need an order for 200-300 guns to tie up logistics,” he said.

    Talking about the next version of the Tejas, called ‘Mark1-A’, Dr Christopher said: “The design other than the AESA radar and the jammer pod is complete.”
    Hindustan Aeronautics Limited is looking to import the AESA radar even as DRDO made a radar that will be tested next month. The IAF is looking at 83 ‘Mark1-A’, with 59 improvements over the existing Tejas.


    The Indian Air Force has projected a need for 324 fighter jets over 15 years and has officially indicated that it needs the ‘Tejas Mark 2’ (medium combat aircraft). It will carry a more powerful engine and weigh almost 20 per cent heavier than Tejas.

    As far as the Uttam AESA is concerned, one prototype is currently being integrated with the business jet that I had mentioned some months ago. Flight trials by the end of the year are likely. A total of 3 SOPs will see airborne testing. 8 prototypes in all will be created.
