The Unmanned Systems, either remotely operated or autonomous to different degrees, have already become a part of defence inventory and are fast becoming a significant part of the combat forces apart from being used for Intelligence, Surveillance and Reconnaissance (ISR). The Unmanned Aerial Vehicles (UAVs) with days of endurance and inter-continental ranges with strike capability are redefining war doctrines and operational tactics. The Naval and Ground Forces are going to be new dominions of Unmanned Systems which was till now dominated by UAVs.
