The development of unmanned aerial systems, or drones was initially for military purposes. As these aerial systems did not require an onboard pilot, they were seen as a useful weapon on the battlefield. Not only does a drone decrease the mortality rate of the soldiers, it also provides the military a chance to spy on the enemy in a discrete manner.Drones have become an important component of national defense for the following reasons.· A drone is an unmanned vehicle, that is, it does not require any one to be on it to be controlled. This is possible because it can be controlled using a remote control. Though it is mandatory that it is still controlled by a trained pilot, it does not require the pilot to go with it.
· The US military has been using drones to search for terrorists in Afghanistan and have proved how useful they are for conducting covert military operations.· Drones can be used for various purposes such as searching for hidden terrorists, gunning the terrorists down in their own areas and searching for the hidden landmines using hyperspectral imaging sensors.· Keeping an eye on the air space of the country.· Keeping a check on the borders of the country without threatening the lives of the most precious soldiers.The use of the US Army’s Global Hawk in the combat field of Afghanistan has already made news. This has triggered a race between countries to own and develop this technology as soon as possible. Countries like UK and China and India are already way ahead in the research and development of drones for their respective defense forces.The use of drones even by the army is not only for combat and espionage purposes. This technology is largely being developed for the times when a crisis hits the nation. The military is trying to use drones in areas that have suffered fire or earthquake where the military and air force is called in to rescue people. This is the humanitarian aspect of the use of drones. Drones are sent in difficult to reach places to search for survivors. When the images from a drone shows the presence of any survivor, special teams are sent in to carry out rescue operation. This has saved many lives and is sure to save a number of lives in future too.
The countries that are trying to be the controlling factors in the world need to have this technology soon. UK has started by bringing together all of its top engineers to develop homemade UAVs and there were news about the flight of their first UAV named Taranis.The use of UAVs cannot replace the fighter jets or the satellites, however, they can be used for surveillance missions that can’t be performed by fighter jets as they are too big and therefore can be spotted quite easily by radar. Drones are definitely one of the “must haves” for any good army in the future.
