Drone technology is advancing rapidly. Drones, also known as unmanned aerial vehicles (UAVs), have evolved from early target practice drones in the early 1900s. There are two main types - military drones like the MQ-9 Reaper used for surveillance and attacks, and commercial/recreational drones like the DJI Phantom for photography. Drones operate through a ground control system where officers can monitor and control a drone's flight path and weapons payload if applicable. New innovations continue to push the boundaries with experimental drones that can both fly and function as submarines.
