Deadly UAVs of Modern Warfare

Like the extermination of dinosaurs that dwell at the early years of the planet some 160 million years ago in the late Triassic to the end of the Cretaceous period, technology seem to follow the same natural pattern, leaving the old to start something new. 

History has it that it started as early as 1916 in what was known as A.M. Low’s aerial target. Unmanned Aerial Vehicles (UAVs), Remotely Piloted Vehicles (RPVs), drones or the present Unmanned Combat Air Vehicle (UCAV) evolved through the years and its existence has now come to threaten the phase out of fielded combat/fighter aircraft for its place in the National Defense inventory. Way back in the 1950’s during the cold war, drones, with the shape of small aircraft is loaded/ towed after a mother ship where it is left in the sky, loaded with remotely operated cameras, they could loiter in high altitude and take photographs of the target before being retrieved. Its evolution over the years with the development of computers and miniaturized electronic components has gone a fast pace eversince. Now they could perform multi-tasks including the equipage of weapons that could hit its target from a distance.
