The National Aerospace Laboratories (NAL) revealed that it is making potent swadeshi (indigenous) Kamikaze drones, do-and-die unmanned aerial vehicles with home-built engines that can power them to fly up to 1,000 kilometres. The drone will be around 2.8 metres long with a wingspan of 3.5 metres, weigh about 120 kg and carry an explosive charge of 25 kilograms.
