The debate over the usage of military drones is largely an ethical one. Many people claim that drones can be seen as an invasive force, that collateral damage is pretty common with armed drones, and that by simplifying warfare, people would lose track of the consequences of war. However, it is difficult to argue the solid result that drones produce. There is a relatively low maintenance cost and the loss of human life is greatly reduced when soldiers don’t have to make a trek into dangerous territory in person. As long as drones continue to provide these services, there will be a use for them and a new country is joining the fold.
Development of military drones is supposed to reduce the risks of soldiers as well as provide more effective renaissance in otherwise inaccessible spaces. The main purpose of the new United 40 is for long endurance reconnaissance and surveillance sorties, with the small possibility of being weaponized in the future. At its completion, the current plan is for the United 40 to perform near instantaneous real time battle surveillance, but ideally it would be able to perform humanitarian tasks as well.
The United Arab Emirates is the latest country to enter the field of military minded drone aircraft. The most unique quality of the new United 40 is a fuselage shaped like a serpent. It’s planned to have an empty weight of 1150 pounds with a maximum take-off weight of around 3300 lbs. The lightness of the drone comes along with an extra-long endurance comes largely from the build. It has a pair of glider-like, high aspect ratio wings.
