Unmanned aerial vehicles - or UAVs - have become an integral part of modern warfare. Their use is so widespread that even non-governmental parties, including ISIS, with its seemingly inexhaustible disposal, fleet quadrocopters, there are whole parks of drones. Almost every army in the world has at its disposal one or another drones - starting from light, launched from the shoulder, UAVs for reconnaissance of the battlefield and ending with the infamous UAVs Predator (Predator) and Reaper (Reaper), or their analogues.
But only a few countries can boast of high-altitude drone with a long duration of flight. The beginning of the Russian flight tests of long-range UAVs Altius shows that Russia will soon join this elite club.
