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.

India’s Dilemma: The Specter of a Three-and-a-Half-Front War

In the first of a two-part series, we examine India’s growing security challenges, both internal and external, and the strategic steps needed to navigate these complexities

The world is a powder keg. Unrest in Iran, Iraq, Israel, Syria, and across the Middle East coincides with the protracted war between Russia and Ukraine. These crises ripple across borders, leaving no country untouched. For India, the stakes are particularly high. In Asia, tensions with Bangladesh and Pakistan, coupled with an unresolved standoff with China, exacerbate an already precarious security environment. Adding fuel to the fire, domestic challenges further intensify the risks, raising the alarming possibility of what strategists dub a “three-and-a-half-front war.”

India’s geographical location offers both an advantage and a disadvantage. Strategically positioned as a hub for global logistics, the country is critical to ensuring regional stability. Yet, its proximity to two longstanding adversaries—China and Pakistan—complicates matters. Bangladesh, with its shifting allegiances, has added a new dimension to this calculus. The volatile domestic situation, marked by communal and political unrest, completes the trifecta, with internal challenges forming the “half front” in this ominous scenario.

Indo-China relations have long tested India’s diplomatic mettle. For decades, China has pursued a strategy to keep India on edge, using a mix of psychological and military provocations. Rooted in its desire to avenge the ‘Century of Humiliation,’ China’s worldview is deeply shaped by a need to dominate its regional neighbours.

India’s rapid ascent on the global stage poses a direct challenge to China’s ambitions of regional and global supremacy. Beijing views New Delhi’s rising stature with unease, particularly its growing influence in the Indo-Pacific, its robust infrastructure along contested borders and its leadership in multilateral forums like the Quadrilateral Dialogue (QUAD). The refusal to join initiatives like the Belt and Road Initiative (BRI) and the Regional Comprehensive Economic Partnership (RCEP) has further strained ties.

The 2020 Galwan Valley clash, a tragic flashpoint in Indo-China relations, epitomized China’s aggressive designs. Beijing’s displeasure with India’s border infrastructure development and its closer ties with Western allies has only fuelled its belligerence. Militarily, China holds the upper hand, leveraging its advanced arsenal against India’s aging defence systems. This disparity emboldens Beijing to test India’s resolve repeatedly, creating a perpetual state of tension.

Beyond its direct provocations, China’s deepening ties with South Asia complicate India’s security calculus. Bangladesh, once a trusted ally, now edges closer to Beijing. Economic investments through the Belt and Road Initiative, strategic military partnerships, and increased political engagement hint at a significant shift in Dhaka’s priorities. While India continues to invest in its ties with Bangladesh, the growing influence of China in the region presents challenges that are impossible to ignore.

Since Partition in 1947, India and Pakistan have shared an acrimonious relationship. Pakistan’s grievances, from the creation of Bangladesh to its inability to annex Kashmir, have defined its hostile posture toward India. While India’s economic growth and diplomatic successes have widened the gulf, Pakistan continues to rely on asymmetric warfare through state-sponsored terrorism.

India has responded firmly with cross-LoC strikes and diplomatic efforts like pushing Pakistan onto the FATF grey list. However, Islamabad’s deepening ties with Beijing, including advanced weapon supplies, have strengthened its military, forging a troubling China-Pakistan nexus. This partnership, with potential strategic collaboration in Siachen and Ladakh, poses a serious challenge to India, raising concerns of a coordinated assault from both adversaries.

Bangladesh, once a close ally, now emerges as a wildcard in India’s security landscape. While the two countries share historical ties rooted in India’s role during Bangladesh’s liberation, recent developments suggest a drift. Dhaka’s growing economic partnership with Beijing and its reluctance to fully endorse India’s regional leadership underscore this shift.

China’s significant investments in Bangladesh’s infrastructure, ranging from ports to power plants, mirror its strategy in other South Asian countries. For India, this growing influence represents not just an economic challenge but a strategic one. The possibility of Bangladesh aligning with China in regional disputes adds another layer to India’s external threats.

The Domestic ‘Half Front’

India’s security challenges are compounded by internal issues like communal tensions, political polarization, and insurgencies in Kashmir and the Northeast, which strain resources and create exploitable vulnerabilities. Kashmir remains a flashpoint, with unrest offering Pakistan opportunities to stoke proxies, while Northeast insurgencies require constant vigilance. To counter the threat of a coordinated three-front assault, India must recalibrate its security policy with investments in defence modernization, strong alliances, and diplomatic finesse.

Modernizing the armed forces, with a focus on indigenization and reducing dependence on foreign suppliers, is imperative. Simultaneously, India must strengthen its regional partnerships, leveraging platforms like the QUAD and the Indian Ocean Rim Association to counterbalance China’s influence. Engaging with Bangladesh to rebuild trust and counter Beijing’s narrative will be equally crucial.

A united and resilient nation is less susceptible to external manipulation, ensuring that the ‘half front’ does not become a full-blown crisis. The challenges are formidable, but so too is India’s resolve.
