Today, the number of different drones has increased, each one having a specific use. For example the reaper: sleek, fast, and deadly. It’s used to go somewhere, take out a target, and return. Its capability for longer flight time is limited. Another is the global hawk: used only for surveillance, its name lives up to its meaning. It can survey up to 40,000 square miles in a day. Lastly, the predator: the #1 drone that is the perfect hunter-gather UAV. It has been used for the mission to track and kill Al-Queda’s, Abu Yahya al-Libi. It carries hellfire missiles that pack a punch. You, the reader are probably being watched by one of these.
The U.S puts millions of dollars into their drone budget for the highest up-to-date technology to add on to the superpower of the skies. Last year, Iran's armed forces shot down a US spy plane that violated Iranian airspace along its eastern border. RQ-170, the drone shot down, had high technology ranging into the billions of dollars. The Iranians have probably copied the technology for their own.
UAV’s have come a long way from the original: camera attached to a glider. Today’s unarmed drones are sold privately around the world for people to experience the thrill of flying around an area behind a TV and a controller.
