Counter-Drone Warfare After 2025 Technologies, Tactics and Battlefield Lessons for India

Counter-Drone Warfare After 2025 Technologies, Tactics and Battlefield Lessons for India

The proliferation of low-cost unmanned aerial vehicles (UAVs) has essentially transforming the character of contemporary conflict. Drones have added to already existing long list of instruments of combat. Due to all-round demands, the global counter-UAS market is only sky-rocketing upwards. India, having experienced the realities of drone warfare firsthand, is now accelerating a multi-layered counter-drone architecture. Based on recent conflicts, this document examines the emergent counter-drone technologies and provides suggestions for India’s strategic roadmap for building a resilient counter-UAS ecosystem.

The Evolving Drone Threat Landscape

The most unsettling feature of any warfare is its devastating cost-exchange ratio and drone warfare is no different. A $500 DIY drone can now destroy a multi-million-dollar aircraft on ground or assist/guide a devastating barrage of artillery fire on critical infrastructure on ground. Ships at are not safe too. In June 2025, Ukraine’s Operation Spiderweb, highlighted the same. Ukrainian officials stated the strikes damaged “one-third of Russia’s strategic cruise missile carriers,” with an estimated total value of US$7 billion, while the drones used cost just $2,000 each. This economic asymmetry is fundamentally unsustainable for sides relying on traditional air-defence systems. The global counter-UAS market is projected to grow from $4.48 billion in 2025 to $14.51 billion by 2030 while some project it to reach $20.31 billion by 2030. Presently the counter drone measures are limited by their ranges for eg the lasers for DEW. In other words, larger the area to be defended more will be the number of counter drone units required. This in turn increases the cost prohibitively. The implication is clear: nations must develop cost-effective counter-drone solutions or risk being financially bled dry by adversaries deploying cheap, expendable UAVs.

In September 2025, Ukraine reportedly became the first nation to deploy an autonomous drone swarm in combat — one capable of coordinating, adapting, and striking with minimal human input. Drone swarms with their inherent redundancy means that limited-ammunition counter-UAS platforms cannot neutralise the entire swarm before some drones penetrate defences. Future drone swarms, powered by artificial intelligence, will make autonomous decisions and adapt tactics in real time. This evolution demands counter-drone systems that can themselves operate without human tailbacks.

Perhaps the most vexing development in 2025 has been the mass adoption of fibre-optic controlled FPV drones. First deployed by Russian forces in early 2024, these drones communicate via hair-thin fibre-optic cables rather than radio signals, making them immune to electronic warfare jamming. Unlike RF-controlled drones, multiple fibre-optic drones can operate in close proximity without interfering with each other. Despite expectations that cable weight would limit range, operational ranges of 20 km are routine, with the longest reported flight at 41 km. NATO has formally acknowledged that “EW counter-UAS systems are ineffective against this type of drone”.

Counter-Drone Technologies After 2025

AI-driven drone detection represents the foundational layer of any modern counter-UAS architecture. Advanced algorithms combined with intelligent networks can identify UAVs and distinguish them from birds, weather phenomena, and other airborne clutter at speeds far exceeding human operators. Satellite-based monitoring, when fused with AI analytics, enables detection of UAVs in remote areas and at elevated altitudes where ground-based radars have limited coverage. India’s SAKSHAM system, exemplifies this approach. Operating on the secure Network, it provides AI-powered 3D visualisation, predictive analysis, and integrated soft/hard kill options across the Tactical Battlefield Space.

Laser-based directed energy weapons (DEWs) have transitioned to operational systems, and try to counter cheap drones without expensive missiles. Their appeal lies in near-zero cost per shot, virtually unlimited magazine depth, and precision that minimises collateral damage.

While lasers engage one target at a time, High-Power Microwave (HPM) weapons offer a unique capability: neutralising entire drone swarms simultaneously. HPM systems emit directed bursts of electromagnetic energy that disable onboard electronics — navigation sensors, communication links, and flight controllers — achieving a “soft kill” without physical debris. DRDO made HPM System is a truck-mounted microwave weapon operating in the S-band frequency range.

Electronic warfare remains the most widely deployed counter-drone technique, though its effectiveness is increasingly challenged by autonomous and fibre-optic drones. Modern jamming systems disrupt drone operations by blocking control signals, GNSS navigation, or deploying GPS spoofing to misdirect hostile UAVs. Russia’s electronic warfare adaptations in Ukraine offer important lessons.

An emerging frontier in counter-drone warfare involves cyber-based countermeasures — hacking into enemy drone command-and-control systems, intercepting communications for intelligence, or taking control of hostile UAVs. Use of available 5G network and Passive coherent locator radars would add to the situational awareness and early warning of an impending drone attack. GPS spoofing countermeasures can defeat hostile jamming attempts while allowing friendly UAVs to operate uninterrupted. AI-driven threat analysis detects anomalies in drone behaviour, identifying malicious hacking attempts before they materialise.

Kinetic interception remains essential, particularly against fibre-optic drones where electronic warfare is ineffective. These range from traditional anti-aircraft guns to novel low-cost interceptor drones. Proximity-triggered explosives designed for swarm-based autonomous operations against enemy loitering munitions. The Bhargavastra system, tested in May 2025, can launch 64 micro-missiles simultaneously, has radar detection at 10 km for medium-to-large UAVs and engagement range up to 2.5 km. Net-based systems: Russian troops built two-kilometre mesh net “tunnels” in early 2025 to physically entangle Ukrainian FPV drones on their final attack trajectory.

Lessons from Russia – Ukraine War

 The Russia-Ukraine conflict is history’s most intensive proving ground for drone warfare, generating unprecedented cycles of adaptation and counter-adaptation. Key lessons are Adaptation speed is decisive and as no single counter-drone system provides comprehensive protection so Layered defence is non-negotiable. Another aspect that has emerged is to evolve from centralized and expensive air defence systems to distributed, lower-echelon solutions where tactical-level electronic warfare and portable counter-drone systems became essential.

Lessons from Op Sindoor

Operation Sindoor, India’s military response following the Pahalgam terrorist attack, marked a turning point in Indian drone warfare doctrine. Pakistan fired waves of drones toward Indian positions, intended to saturate air defences and map Indian systems. Indian forces deployed a mix of hard-kill and soft-kill counter-drone systems. As Chief of Defence Staff Gen. Anil Chauhan stated, “none of them could actually inflict any damage” on Indian infrastructure. The IDDIS, developed by DRDO and manufactured by BEL, successfully destroyed several low-radar-cross-section drones during the conflict. Its dual soft-kill (RF jamming, GNSS jamming, GPS spoofing) and hard-kill (laser) approach proved effective in operational conditions.

India’s Counter-Drone Architecture and Roadmap

Drones are now viewed as essential elements of warfare rather than niche assets. India has notably intensified its focus on unmanned aerial vehicles (UAVs), not just in procurement but across training and doctrine. India has rapidly expanded its counter-drone ecosystem since 2025, with multiple systems now operationalised or in advanced testing.

IACCS of IAF along with the Akashteer system, (developed by BEL), will provide a unified air situation picture accessible to the lowest operational units. During the May 2025 conflict, this combination proved critical in neutralisation of enemy aircraft, drones, and unmanned combat aerial vehicles across a multi-layered air defence network. This integration framework is essential for India’s counter-drone strategy, ensuring that individual C-UAS systems do not operate in silos. India needs to develop a layered detection and cascading neutralisation grids for the VAs and VPs.

Policy and Doctrinal Shifts

Operation Sindoor has catalysed major policy and doctrinal changes like drone incentive programme announced to accelerate indigenous drone and counter-drone production.

“Eagle in the Arm” doctrine which aims to train every Indian soldier in drone operations by 2027, (treating UAVs as the “third arm” of infantry) is another doctrinal change being affected. Drone Framework by Ministry of Defence which is crafted to incentivise local production, mitigate risks of imported flight controllers (flagged for potential malware/backdoors), and streamline testing is yet another policy shift.

The Layered Defence Imperative

No single technology provides comprehensive protection. The unanimous lesson from Ukraine, Operation Sindoor, and global C-UAS research is that layered, integrated defence is the only effective approach. One of the important aspects to isolate rogue drones would be development of Military UTM (Unmanned Traffic Management) system at the earliest. India’s emerging architecture focuses on a Detection Layer which has AI-powered radars, RF sensors, EO/IR cameras, and acoustic detectors fused through SAKSHAM, IACCS and Akashteer networks. A Soft-Kill Layer which includes RF jamming, GNSS disruption, GPS spoofing, Hard-Kill Layer (Close Range) with Laser DEWs at 2–5 km range and a Hard-Kill Layer (Area Defence) with HPM systems for swarm neutralisation. Cyber take over is also important to prevent drones from reaching the intended target, needs a mention here. The Kinetic Layer will have Bhargavastra micro-missiles, legacy AD guns, counter-drone interceptor drones. All these layers will be unified for a command & control, situational awareness and automated threat response by IACCS and Akashteer.

Strategic Recommendations for India

Aim should be to have an Integrated Detection-to-Neutralisation Kill Chain. The sequence of actions in this should be multi-sensor detection (radar + acoustic + EO/IR + RF) followed by AI fusion & threat classification, Autonomous prioritisation, leading to a Soft-kill attempt, failing which should be a Directed energy engagement and a Kinetic fallback.

Post-engagement BDA and Launch-site geolocation are a must. These systems can be Unified under: Integrated Air Command and Control System and Akashteer.

Despite impressive progress, the counter-drone production ecosystem in India must scale proportionally to match the likely threat volumes. India’s current C-UAS architecture is heavily weighted toward RF-based electronic warfare, which is ineffective against fibre-optic controlled drones. Investment in kinetic micro-interceptors, HPM systems, and AI-enabled detection of fibre-optic drone launch sites must be prioritised. Achieving all-weather reliability requires either improving laser performance in adverse conditions or supplementing with weather-immune kinetic systems. India’s reliance on foreign systems for critical capabilities remains a vulnerability. The DRDO-led indigenisation programme must accelerate domestic alternatives. India has to develop autonomous decision-making systems capable of engaging hundreds of incoming drones simultaneously without human bottlenecks along with leveraging the private sector ecosystem for mass production at competitive costs. In another alternative to radio control, Ukrainians have begun attaching Starlink terminals to drones. This allows them to fly using satellite internet. Work should be done to fight against the satellite internet. Thought should be given to extend the “Eagle in the Arm” type doctrine to include counter-drone tactics at every level. Alongside jamming, Ukraine has also developed cheap interceptor drones built specially to destroy other craft mid-air. India could think on these lines too. Finally, engage with competitive foreign counter-drone innovations to cross-pollinate technologies and accelerate development.

 Conclusion

The post-2025 battlefield is without doubt afflicted by the cheap and increasingly autonomous drone. India’s experience in Operation Sindoor validated its indigenous counter-drone capabilities while exposing some gaps. The path forward requires a layered defence architecture integrating AI-powered detection, directed energy weapons (both laser and microwave), electronic warfare, kinetic interceptors, and robust command-and-control networks. India’s strategic advantage lies in its rapidly maturing defence-industrial base — public-private innovators and academia -industry research— combined with the operational experience gained in real combat. The nations that master counter-drone warfare at scale will hold the decisive advantage in the conflicts of tomorrow.
