The KALI (Kilo Ampere Linear Injector) 5000 is a linear electron accelerator being developed in India by the Defence Research Development Organization (DRDO) and the Bhabha Atomic Research Centre (BARC). It is not a laser weapon as commonly believed. It is designed to work in such a way that if an enemy missile is launched or any unknown fighter plane in Indian direction, it will quickly emit powerful pulses of Relativistic Electron Beams (REB) and destroy the target. Unlike laser beams, it does not bore a hole in the target but thoroughly damages the on-board electronic systems.
