The Beam That Blinds the Drone

As cheap drones reshape the battlefield, India’s T-SHUL BEAM points to a future in which electronic warfare may matter as much as firepower The drone has definitively become the weapon of choice for the modern battlefield. Cheap, expendable and increasingly autonomous, unmanned aerial vehicles can now threaten troops, armour, airfields and critical infrastructure without requiring the attacker to risk a pilot. Their proliferation has created a corresponding demand for counter-drone systems that can respond quickly and at a cost proportionate to the threat. This is where beam-based anti-drone technology enters the picture. Broadly, such systems fall into two categories. Hard-kill systems use concentrated laser energy to physically damage or destroy a drone. Soft-kill systems, by contrast, use radio-frequency or electromagnetic energy to disrupt the electronic links that allow a drone to communicate, navigate and transmit information. Sophisticated Weaponry Hard-kill laser systems focus an intense beam of light on a vulnerable part of an incoming UAV - its carbon-fibre structure, control surfaces, battery or other critical components. The concentrated energy rapidly heats the target, potentially burning through its structure or disabling optical sensors and bringing the aircraft down. India’s DRDO has demonstrated a 30kW laser system, while Israel’s Rafael has developed the Lite Beam system. Soft-kill systems take a different route. Rather than physically destroying the aircraft, they interfere with the electronic architecture that keeps it airborne. Directional radio-frequency energy can disrupt command-and-control links, video feeds, telemetry and satellite-navigation signals such as GPS or other GNSS services. Depending on the drone and the nature of the disruption, the aircraft may be forced to land, return to its launch point or lose control. It is in this category that the T-SHUL BEAM system developed by Indian defence company IG Defence deserves attention. T-SHUL BEAM is a man-portable, directional counter-drone system designed for tactical deployment. Its multi-band radio-frequency architecture is intended to target several of the links on which unmanned aerial systems depend, including command-and-control, telemetry, video transmission and GNSS navigation. Its directional configuration allows an operator to concentrate electronic countermeasures on a particular aerial target rather than indiscriminately radiating energy across a large area. That matters on a battlefield where the warning time against a small UAV or first-person-view drone may be measured in seconds. The appeal of such a system is therefore not simply that it can counter a drone. It is that it can potentially bring counter-drone capability closer to the soldier and to the tactical edge. Large counter-UAS installations have their place, particularly around fixed and high-value assets. But forward units require systems that can move with them, be deployed rapidly and operate against small, low-cost unmanned platforms without imposing the logistical burden associated with conventional weapons. The T-SHUL BEAM’s significance also lies in its proposed integration with an artificial-intelligence-enabled battle-management architecture. IG Drones, the original equipment manufacturer, has stated that T-SHUL BEAM has been integrated with GRID, its indigenous AI-powered platform. The GRID architecture is intended to bring sensors, intelligence systems, unmanned platforms and command elements into a common operational framework. The attraction of such integration is obvious. Countering drones is increasingly less about a single weapon and more about the speed of the kill chain: detecting a threat, identifying it, deciding what response is appropriate and directing that response before the target disappears. An AI-enabled command architecture can potentially improve situational awareness, facilitate real-time threat detection and coordinate different systems operating simultaneously. This is particularly relevant as drone warfare evolves from isolated attacks towards increasingly complex and potentially swarming operations. A battlefield crowded with drones cannot be managed effectively if every sensor and weapon operates as a separate island. The advantage will increasingly belong to forces capable of turning disparate streams of information into a coherent picture and responding at machine speed. The T-SHUL BEAM’s reported demonstration at Pokhran represents another step in India’s attempt to build a domestic ecosystem spanning drones, counter-drones, artificial intelligence and electronic warfare. Counter-drone warfare is likely to be a recurring requirement rather than a niche capability. Importing every component of such an ecosystem would leave India vulnerable to supply-chain disruptions, technology restrictions and foreign-exchange pressures. Indigenous development, even when undertaken by relatively small private-sector companies, can broaden the country’s technological base and give the armed forces greater freedom to adapt systems to their operational requirements. Economics of the Contest Yet the real measure of any counter-drone system will ultimately be operational rather than promotional. Electronic warfare is inherently a contest between countermeasure and counter-countermeasure. Drone designers can alter frequencies, communications protocols, navigation methods and levels of autonomy. A system that is effective against one generation of drones may require modification against the next. The battlefield, in other words, will remain a technological arms race. The economics of the contest nevertheless favour directed-energy and electronic-warfare solutions. A conventional interceptor expends a missile or projectile against each target. A beam-based system can, subject to its power supply, engagement envelope and other operational constraints, engage targets without expending conventional ammunition. The marginal cost of an interception can consequently be dramatically lower. The beam also travels at effectively the speed of light, removing the flight time associated with kinetic interceptors. In densely populated areas or around sensitive infrastructure, bringing down a drone with a projectile can create its own hazards. Electronic disruption, when properly controlled, offers the possibility of neutralising the threat without sending an interceptor crashing back to earth. These advantages should not obscure the limitations. Soft-kill systems depend on the vulnerabilities of the target’s electronic architecture and may be less effective against increasingly autonomous drones that require fewer external communications. Weather, range, power availability, frequency management and the sophistication of an adversary's electronic countermeasures can all affect performance. No single technology is likely to provide a complete answer. The future of counter-drone warfare will therefore belong not to the beam alone but to layered defence combining. The emergence of systems such as T-SHUL BEAM suggests that India is beginning to build the technological pieces of that architecture at home.

Bharat’s Jetson Cities, Light-years Away from Nature

Jetson Cities

One thing is for certain: our Bharatiya cities, the big metros and towns, are fast becoming like the ‘Jetson’ cities. For those who are unaware of Jetson cities, these were first shown in the famous Hanna-Barbera cartoon series, the Jetsons, set in the 2100s, where cities are air-tight glass globules tethered to the ground, and the only way to get in and out are the flying cars. Yes, we, the city-dwellers, aspire to tall skyscrapers, spectacular bridges, world-class tunnels, swooshing metro trains, and we are building Jetson-like flying cars. A few HD drone images here and there, during the day and at night and around twilight, and we are content that our cities have become the cynosure of our own eyes. We want our cities to be brightly lit, with neon signs, laser shows, and large billboard videos. We would then fulfil our inner desire to have a city on par with Tokyo, New York, and Shanghai.


Our buildings, designed for the next 30 years, are well air-conditioned, shielding occupants from a soupy dust bowl of brown smog, soot, particulate matter, and fine dust. It is said that most new home buyers invest at least 10% of their property’s price in enhancing the interiors, soundproofing their homes, using air purifiers and conditioners, and disconnecting from the outside world for that much-needed solace. Indeed, large builders promote their projects as close to nature amidst tranquillity. However, there is always another builder eager to get one plot of land ahead of yours to enjoy that nature. To be truthful, access to nature now comes at a premium - even the skies.


Let’s assume the working-age population is occupied in the leisure of our Jetson cities, but how many of their young school and college-going kids have seen the long arm of the Milky Way galaxy from their cities? How many have witnessed a comet zooming by? How many know about endemic plants with medicinal properties? When did they last see a chirping house sparrow? How many know that the nearest sewage drain was once a freshwater stream? When did they last find their suburban beach prettier than the resort beaches of Maldives?


The intent to ask these questions is simple: Bharat is currently at a crossroads. Pundits are enthusiastic about a cultural renaissance on the horizon. Corporate leaders, on the other hand, want us to invest hundreds of hours each week to pay our dues to the growth of the national GDP. But no one asks, if a cultural renaissance is to occur, who will generate the new understandings and insights of nature that arise typically during such a period of human advancement? No one is actually asking, for whom are we building the nation if there is no time for children, or worse, if there is no time or intent to have children. In the process of growing rich, we are about to become old. By 2047, 65% of the population under the age of 35 will grow beyond 35 all at once, and we’d have an enormous population in advanced ages with a tapering young population, a graph that looks like a banyan tree. Unfortunately, that young population will have no access to the knowledge that nature has to offer, neither flora and fauna nor the seas and the skies.


Our urbane lifestyles need tempering. Such tempering can occur only if we ensure the revival of natural sciences during this period of cultural renaissance and nation-building. Let’s not rely solely on the educational system. With Indian Knowledge Systems, constructive changes are underway, and academic curricula are poised to improve for the greater good. However, true knowledge arises only when parents and grandparents introduce children to nature. Genuine understanding also develops from extracurricular activities in schools and colleges that encourage kids to observe, journal, and act on their discoveries. On the positive side, our country’s forest cover is increasing, as announced by the government. However, efforts must be made to ensure that every school or college, whether in Mumbai, Vijayawada, Gorakhpur, Ratlam, Thrissur, Bhuj, Faridabad, Imphal, Manali, Cuttack, or Ajmer, guarantees that their students are well aware of the endemic nature of their surroundings and are regularly observing and recording data on whatever interests them. Let kids observe rivers and understand the volume of water that flows through them. Let children learn about the decline of house sparrows in their cities and what steps should be taken to revive their populations. Let them study the bees in their nearby groves and recognise the vital role these bees play in nature.


Of course, you need to learn AI, robotics, fintech, the next generation of management courses, and all the engineering bells and whistles. However, we must not leave the next generation with inadequate comprehension and skills for understanding nature. We must ensure that nature conservation is not merely lip service or a tool for politicised green activists. This can be achieved if natural sciences are given the respect they deserve at the school, undergraduate, and postgraduate levels.


Indeed, I am a plebeian, and you might feel that you, too, could write a rant about the plight of our urban lives. Urban development and municipal experts have many solutions to propose, but few are willing to take action. However, that is not the issue I wish to highlight. I aim to illustrate a much larger concern—that Indian city dwellers are disoriented and devoid of nature, lacking a guiding star to lead them toward a brighter future. Our cities of Mumbai, Delhi, Bengaluru, Ahmedabad, Kolkata, and Chennai have taken on characteristics reminiscent of Jetson-like cities. We show little regard for the Nagar Devata, Gram Devata, and Van Devata, who have protected the cities, towns, and forests that once surrounded us. We wait for formal governance to clean up our beaches, rivers, and ponds without making sufficient efforts to prevent pollution in the first place.


For those striving to grasp spirituality not through the Puranas and Aadi-Granth but through new-age podcasts, I recommend watching Vinay Varanasi’s podcast on Bhagavan Vishnu’s Dashavatar. If it is clear that Bhagavan Vishnu does not tolerate disregard for Bhudevi or Mother Earth, why do we, the devotees of Bhagavan Vishnu, continue to pollute our Mother Earth—her air, soil, waters, and sounds? Or have we taken Elon Musk's words at face value, assuming our next destination is Mars after destroying Earth, only to ruin Mars later, even worse than its current clinically sterile state? If that is the case, then bear with me when I say this: these Jetson cities stand on precarious pillars of ego, victimhood, apathy, and consumerism, waiting to be toppled either by the true harbingers of order or by false prophets. Therefore, teach the next generations to observe nature, appreciate our coexistence with other species, and venerate the forces of nature. By doing so, we humans will be good, at least for the next thousand years. If not, prepare for a bleak future by the end of this century.
