Silent, cheap & deadly: Why lasers are a gamechanger in air defence - where India stands

Silent, cheap & deadly: Why lasers are a gamechanger in air defence - where India stands Laser weapons, once confined to science fiction, are becoming reality in modern warfare. Militaries worldwide are investing in directed-energy systems capable of disabling drones, missiles and even aircraft with pinpoint precision. Lasers offer near-instant engagement and—so long as power is available—no risk of running out of ammunition. Directed energy weapons (DEWs) could transform air defence, where speed and accuracy matter most. For India, pursuing laser weapons is not just about keeping pace with global trends but about building a self-reliant, comprehensive defence ecosystem.India is developing DEWs in response to a growing regional threat from drones and ballistic missiles. Pakistan has increasingly used drones for surveillance and attacks, while China continues to expand its missile arsenal. Conventional air-defence systems such as missiles and guns remain effective, but they are costly and limited in endurance. Lasers, by contrast, promise a sustainable way to neutralise swarms of drones or incoming projectiles at a fraction of the per-shot cost, making them an attractive addition to India’s layered air-defence architecture.The Defence Research and Development Organisation (DRDO) has begun work on indigenous laser weapons under Project Sudarshan Chakra, aiming to integrate high-energy lasers into India’s air-defence network alongside systems such as Akash and upcoming VSHORAD platforms.
