The drone has become the defining weapon of contemporary conflict — cheap, expendable and, increasingly, autonomous. When drones arrive not one at a time but in coordinated swarms of dozens or hundreds, traditional air defence built around expensive interceptors simply cannot keep pace. Defeating a ten-thousand-rupee drone with a ten-lakh-rupee missile is a losing economic exchange.
Counter-drone, or counter-UAS, technology is the urgent response. It spans a layered kill chain: detection through radar, radio-frequency scanning, acoustic and electro-optical sensors; identification using AI that distinguishes a hostile swarm from a flock of birds; and neutralisation via jamming, spoofing, directed energy, or hard-kill interceptors.
The hardest problem is the swarm itself. Autonomous swarms adapt, disperse and reconverge, sharing intelligence between units. Countering them demands AI that can track many targets at once, predict swarm behaviour, and orchestrate a proportionate response in real time — exactly the fusion of AI, autonomy and edge computing at the heart of the Bengaluru colloquium.
India's exposure is acute along its borders and around critical infrastructure, airports and strategic installations. A thriving cluster of Bengaluru startups is now building indigenous detection radars, RF sensors and soft-kill systems, reducing reliance on imported solutions.
At the BDTS Bengaluru Strategic Colloquium on 3 September 2026, counter-UAS will be a live theme — connecting the engineers building anti-swarm AI with the armed-forces users who need it and the procurement pathways that can field it fast. For founders in this space, few rooms in India offer a more direct route from prototype to deployment.
