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.

Knives out in legislature

Disha Salian

Mumbai: Death of celebrity manager Disha Salian in 2020 once again rocked the Maharashtra legislature on Thursday. While cabinet ministers Nitesh Rane and Shambhuraj Desai demanded that Shiv Sena (UBT) leader Aditya Thackeray be arrested in the case, BJP MLA Amit Satam in the assembly and another BJP member Chitra Wagh in the council demanded that the report of SIT to probe Salian’s death be made public.


Incidentally, amidst repeated disruptions in both the houses, some members from the treasury benches were seen speaking in favour of Aditya Thackeray, while Shiv Sena (UBT) members like Adv Anil Parab were seen supporting the BJP members’ demand that the report of the SIT probe be made public. In addition, there were allegations and counter allegations and personal accusations among members from the treasury and opposition benches which led to heated debate on occasions.


The opposition termed the attempts from the treasury benches to link Shiv Sena (UBT) leader Aditya Thackeray’s name in the case, as a ‘conspiracy’.


“I think this matter has gone to the court. We have no idea what he (Disha’s father) has said, but Aaditya Thackeray is a mature leader, a young leader. The Bharatiya Janata Party is conspiring to defame him by putting pressure on him. We don’t need to answer to this conspiracy. The court will answer,” Ambadas Danve said.


Earlier in the day, when the house gathered for the business, Minister of State for Home appraised the assembly of the status in this case. “SIT has been formed to probe in the case. Their report has not been received as yet. However, the government shall act according to directives from the court,” the minister told the house.


Another BJP minister Nitesh Rane, however, said that since Satish Salian has levelled allegations against an MVA minister, that leader be treated like a common person and that everybody should be treated equally before the law. Shiv Sena minister Shambhuraj Desai too supported the demand. “Since the allegations are grave, the person in question should be immediately arrested and the case be investigated,” he said.


Later, while speaking to media in the legislature premises, Rane asked Uddhav Thackeray to come clean on the issue. “If they say that we are politicizing the issue, Uddhav Thackeray should also tell the people why he had called, not just once but twice, to the then union minister Narayan Rane urging him to save his son?” Rane said.


He also accused the opposition of shying away from coming clean on the issue. “If they feel that we are not telling the truth, they should say so in the house. But they are shying away from doing so. Bhaskar Jadhav, who is always aggressive, was nowhere to be seen when this issue came up in the house. Sunil Prabhu too escaped the house under the pretext of a phone call. I challenge them to say that whatever I said on the issue is wrong,” Rane said.


He also said that Aditya Thackeray should resign on moral grounds till his name is cleared in the case.


BJP MLA Amit Satam demanded that the details of the SIT probe be made public so that the people would know if the probe is headed in right direction.


Interestingly, while the ruling parties were targeting the opposition in the case, senior BJP leader Sudhir Mungantiwar surprised all with his unexpected support to Thackerays. “I do not have any evidences in the case. But if her father has made any fresh allegations that needs to be investigated thoroughly. The assembly can discuss the issue at length tomorrow. In the meanwhile, members like Rane, who seem to have some evidences in the case should hand them over to the investigating agencies and help the probe,” he told the house.


Shiv Sena’s Sanjay Gaikwad and Sheetal Mhatre too toed the line and demanded that more and more evidences should come forth.


Similarly, when members of treasury benches were pushing for revealing the details of the probe till date to the public, Shiv Sena (UBT) member Anil Parab supported the demand. “Doing that shall conclusively prove the innocence of Aditya Thackeray,” he said.
