Modern drones fulfill these requirements to a great extent as timely and accurate information acquisition is very important for the success of all military projects. The machines are able to provide continuous surveillance and a complete and accurate picture of enemy resources in order to plan a successful combat.
Drones have also been used extensively for weather research and monitoring. There is a need to inform the concerned authorities especially the Navy in case of a dangerous weather. If there is a failure to forecast a bad weather, it results in great loss of transport, cargo, and precious human lives.
