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.

Lateral upgrade to ailing annihilation

Being the first person from the private sector to be appointed as chairperson of Securities and Exchange Board of India (SEBI) as part of the government’s lateral initiative, Madhabi Puri Buch also holds the honour of being the first woman to hold the top post as capital market regulator.

But the laurels that the former private sector banker enjoyed in her earlier stint with ICICI Bank, was marred with allegations that she and her husband were having a stake in offshore entities, which were used to artificially inflate shares of Adani group companies.

Terming the allegation as `character assassination, Buch clarified that all disclosures have already been furnished and the fund in question did not invest in any securities involving the Adani group.

When it rains, it pours. This allegation was subsequently followed by Congress Party allegation that Buch had received salary and post-retirement benefits from ICICI Bank after she quit the private sector bank.

In its clarification to the stock exchanges, ICICI Bank asserted that the payments made to Buch were purely retirement benefits after her exit from the bank and they were neither salary nor employee stock options.

Prior to these allegations, Buch tenure at SEBI was all about bringing in quick reforms on operational issues by changing the format of consultation paper to bring in larger responses digitally. Being data savvy, the rationale of her decisions were democratic based on big data analysis derived from the responses received to the consultation papers.

Further she bifurcated the duties of the SEBI staff between operations and enforcement, which were done by the same persons earlier. Having worked for the private sector in the capital market domain space, Buch had a better understanding of the subject compared to officers from the administrative service in the past that reflected even in her orders as a whole-time director at SEBI before becoming the chairperson. As a whole time director at SEBI, her orders on adjudication issues were more directional to the capital market space, according to experts in the compliance space. She was also quick to revamp the old provisions of the 90s at SEBI.

Being tech and data savvy, Buch enhanced regulatory surveillance and detection of market manipulation, insider trading and fraud while also emphasizing on strengthening corporate governance by introducing stricter rules for independent directors and enhancing disclosures for related-party transactions.

To put in perspective, the annual report of the capital market regulator in the just concluded financial year revealed that the number of investigations related to insider trading jumped to 175 in 2023-24 from 85 in the preceding year while probes related to front running jumped over three times to 83 from 24 in the preceding year.

Transparency in mutual funds by implementing measures to protect retail investors along with tightening norms for initial public offers, particularly in the SME platforms were some of her other positive initiatives including confirmation of denial of any market rumours within 24 hours for the top 100 listed companies which will be extended to top 250 companies from December 1. However increased transparency and compliance with tightening regulations led to increased operational costs for the market participants and hence faced resistance from certain quarters. Born in 1966, Buch completed her primary education in Mumbai and graduated with specialization in Mathematics from Delhi and later obtained a management degree from Indian Institute of Management, Ahmedabad. In between, she got engaged to Dhawal Buch, a director at a consumer goods multinational at the age of eighteen and got married at the age of 21.

Besides ICICI Bank, Buch also worked as a lecturer at a college in England, worked at Greater Pacific Capital in Singapore and ICICI Securities as its CEO. She also worked as executive director on several private sector companies and as a consultant for New Development Bank (Brics Bank).

What now remains to be seen, is whether Buch, who survived the 26/11 terror attack when she along with her husband, was attending a meeting at Taj, be able to overcome the current ordeal. Keeping fingers crossed for the times to come.
