DIAT ramps up focus on semiconductor design, defence & space electronics, quantum tech in wake of Op Sindoor
Amidst an increased push for niche indigenous technologies in the backdrop of Operation Sindoor, Defence Institute of Advanced Technology (DIAT) has started a specialised programme — with another to be launched — in semiconductor design and defence and space electronics, said DIAT Vice Chancellor Dr BHVS Narayana Murthy on Thursday. He added that a futuristic quantum technology laboratory will also be launched. Dr Murthy was speaking at a curtain raiser event for the 14th Convocation Ceremony of DIAT which will be held on August 9. The convocation will be presided over by chairman of Defence Research and Development Organisation (DRDO) and secretary of Department of Defence Research and Development, Dr Samir V Kamat, who is also the chairman of the Governing Council of DIAT. DIAT, which is an autonomous organisation of the Department of Defence Research and Development, offers post graduate programmes — including MTech, MSc and PhD — that are tailored towards defence and security applications. Dr Murthy said, 'After the recent Operation Sindoor, a lot of thrust is being given by the government and the tri-services to the indigenous weapons systems and defence technologies. There is a lot of thrust on getting skilled human resources in this area. To that end we launched an advanced course in semiconductor chip design — an area which has seen a lot of government push and another one in Defence and Space Electronics — which will cater for advanced defence and space payload electronics research. To encourage more systems engineering concepts, we are introducing an industrial system engineering programme for working professionals which will be conducted in hybrid mode on weekends.' 'As part of the DRDO reforms, DIAT has been chosen as the main institute to offer MTech in Defence Technology programme for its new recruits. We are successfully conducting a course for the Ministry of Home Affairs to train Cyber Commandos for six months. The first batch completed its course and the second will soon join. The DIAT is also involved in niche and advanced research areas with key defence applications. One of them is free-space high data laser communication, in which we have successfully demonstrated proof of concept. Our quantum technology group is also involved in key research, particularly quantum communication, quantum sensing, quantum computing and quantum key distribution. A dedicated quantum research laboratory is set to be inaugurated,' Dr Murthy added. 'Our Electronics and Physics Departments are working on photonics based electronic warfare systems and radar sensor systems. Many technologies which are a result of indigenous research have been completed and inducted. Like we saw in Operation Sindoor like Akash, Brahmos and direct energy weapons. In the coming years, the projects that are in the final stages of development, will undergo user evaluation trials and will be inducted into the forces. And the industries including PSU will play a major role in the process,' he said. Answering questions on the success of homegrown guidance, tracking and sensing systems during Op Sindoor and ongoing work in these areas, Dr Murthy said, 'DIAT is conducting PG courses like aerospace, which covers guide missiles, UAV and air armaments. We have a course in radar and sensing technology.' Speaking about research futuristic technologies, he said, 'One is free-space high data laser communication. With space being a domain of warfare, we are giving a thrust to space payloads as part of the defence and space electronics programme. The quantum group is working on quantum sensors. There is ongoing research on photonics based radars which will make the systems compact and also give systems jamming immunity. We are also working on advanced material for aircrafts and missiles. Many recent conflicts globally have highlighted the use of drones not just for surveillance but actual combat. Swarm drones are also a key sector. Our teams are working on various aspects including the anti drone systems.'

INTELLIGENT TEXTILES, desert warfare systems and wargaming technologies are some of the key areas that have been identified by the Ministry of Defence (MoD) as part of the Deep Tech research under Technology Development Fund (TDF). A separate allocation of Rs 500 crores has been made for these advanced technology projects with defence applications, informed Minister of State for Defence Sanjay Seth in a written reply to MP Naveen Jindal in the Lok Sabha recently. Jindal had sought to know if the government had approved the new Deep Tech and Cutting-Edge policies under the Technology Development Fund (TDF) Scheme and if so, sought details of the projects along with their key features and objectives. Seth said in his reply, 'An additional grant or corpus of Rs 500 crore has been approved by the Defence Minister to cater for deep-tech and cutting edge projects as separate verticals under TDF. The process of the selection and identification of Deep Tech projects has been initiated. Currently, nine projects are launched under this initiative by TDF.' He added that nine industries are engaged in four projects sanctioned through DRDO Industry Academia Centres of Excellence (DIA-CoEs) under the grants in aid scheme of DRDO. Seth told the House that the projects cover research areas such as Intelligent Textile Technologies, Desert Warfare Technologies, War-gaming Technologies, Powder Metallurgy, High Power Microwave Sources and Devices, Advanced Ballistics, Photonic Technologies, Aerospace Systems and Materials, Micro and Nano Systems Science and Technology, Artificial Intelligence and Robotics, Quantum Technology, Naval Systems and Naval Technologies, High Power CW Laser Source, Additive Manufacturing, Advanced Materials and Processing, Advanced Nano Materials and Sensors based on Semiconductors. Intelligent Textiles are fabrics that can sense, react, or adapt to environmental conditions or user input. Desert Warfare systems are military equipment and mechanisms specifically designed for effective combat operations in hot, arid, and sandy desert environments. Wargaming Technologies and essentially simulation tools are softwares used to model military operations for training, planning, and strategic decision-making. Seth also provided a list of 55 institutes from 20 states in India that have undertaken a total of 302 projects in these areas. These include two institutes from Pune including Defence Institute of Advanced Technology (DIAT) and the College of Engineering, Pune (COEP).

Pralay and Akash Prime missiles: Why are they relevant for UPSC Exam
Take a look at the essential events, concepts, terms, quotes, or phenomena every day and brush up your knowledge. Here's your UPSC Current Affairs knowledge nugget for today on Pralay and Akash Prime missiles. (Relevance: Various missiles, air defence systems, fighter jets, and aircraft types are some of the important topics of defence technology that have been asked by UPSC in prelims. In 2018, a question was asked on Terminal High Altitude Area Defence (THAAD). In this context, understanding the unique weapons becomes crucial.) The Defence Research and Development Organisation (DRDO) conducted two consecutive successful tests of quasi-ballistic missile Pralay from Dr APJ Abdul Kalam island off the coast of Odisha on 28th and 29th July. Three Pune based facilities of the DRDO have played a key role in the development of the tactical weapons system. 1. The flight tests were carried out as a part of user evaluation trials to validate the maximum and minimum range capability of the missile system. 2. 'Pralay is an indigenously-developed solid propellant quasi-ballistic missile employing state-of-the-art guidance and navigation to ensure high precision. The missile is capable of carrying multiple types of warheads against various targets.' said the Ministry of Defence. 3. The first test of Pralay (which means widespread destruction) was conducted in December 2021. The missile is slated to be armed with a conventional warhead and will be inducted into the artillery of the Indian Army. 4. The system has been developed by Hyderabad-based DRDO facility Research Centre Imarat in collaboration with other facilities including three Pune based firms—Armament Research and Development Establishment (ARDE), High Energy Materials Research Laboratory (HEMRL) and Research & Development Establishment, Engineers (R&DE). 5. The ballistic missiles are a category of missiles that utilise projectile motion to deliver warheads. During their arched trajectories, the ballistic missiles are powered during their initial travel but later take a gravity driven path. 6. The quasi ballistic missiles are a class of missiles that have low trajectory and take the ballistic trajectory but can change course and make maneuvers during the flight if required. 1. The Akash Prime missile, which is the upgraded variant of the Akash weapon for the high-altitude region, was successfully tested in Ladakh on 16th July as destroying aerial high-speed unmanned targets with pinpoint accuracy. 2. The trials were done as part of the first Production Model firing trial and will further enable timely induction and enhance the Air Defence potential in high-altitude frontiers of the country, the Ministry of Defence said. 3. The initial version of the Akash missile has an operational range of 27 to 30 kilometers and a flight altitude of around 18 kilometers. The Akash Prime, which underwent its maiden flight test in September 2021 has the same range as that of the earlier version but has a crucial new addition of an indigenous active Radio Frequency (RF) seeker for improved accuracy to hit the aerial targets. 4. Other key enhancements in Akash Prime ensure more reliable performance under low-temperature environments at higher altitudes. These new additions have been made after receiving feedback from armed forces, for the deployment of the system to provide air defence cover for vital installations and sensitive areas in high-altitude regions. The weapon system is customised to operate in altitudes above 4,500 metres, the MoD has said. 5. Notably, the development of the Akash, a short to medium range surface to air missile, was started by the DRDO in the late 1980s as part of the Integrated Guided Missile Development Programme. The early systems trials, field trials and target neutralisation trials were conducted in the late 1990s and early 2000s. These were followed by the extensive user trials by the Indian Air Force and Indian Army. 6. Named after the original Sanskrit work for sky, Akash symbolised the deterrence in the air. It is primarily designed to provide air defence cover to the vulnerable areas and critical installations. 7. The Akash weapon system can simultaneously engage multiple targets in group mode or in autonomous mode. It has built-in Electronic Counter-Counter Measures (ECCM) features, which means that it has mechanisms on-board that can counter the electronic systems that deceive the detection systems. 1. Ballistic missiles use projectile motion to deliver warheads to a target. They are powered for a relatively brief time, after which they let the laws of physics take them to their target. These missiles are categorised based on range. Ballistic missiles can carry either nuclear or conventional warheads. Examples of ballistic missiles are Agni I, Agni II, Prithvi I, Prithvi II and Dhanush missiles. Source: UN Office of Disarmament Affairs (Note: This categorisation is not fixed.) 2. Cruise missiles are unmanned vehicles powered by jet engines that can be launched from ground, air, or sea platforms. Examples of cruise missiles are BrahMos,Tomahawk,Kalibr, AGM-86 ALCM and JASSM. 3. The cruise missiles fly at a low distance from the ground while the ballistic missiles follow a parabolic trajectory. Ballistic missiles are easier to track since they have a standard parabolic trajectory, as compared to cruise missiles which can fox air defence systems due to their manoeuvrability. (1) With reference to the Pralay missile, consider the following statements: 1. It is an indigenously developed solid propellant quasi-ballistic missile. 2. This missile is capable of carrying multiple types of warheads against various targets. 3. The first test of Pralay was conducted in 2024. How many of the statements given above are correct? (a) Only one (b) Only two (c) All three (d) None (2) Consider the following statements about the Akash Prime missile: 1.
