The word drone was first used for an unmanned aerial vehicle in 1946, but advances in drone technology in recent years have made the term much more common. During the interwar period, the development and testing of drones continued. In 1935, the British produced several drones for use as training objectives. It is believed that around this time the term “drone” began to be used, inspired by the name of one of these models, the DH 82B Queen Bee.
Radio-controlled drones were also manufactured in the United States and were used for target shooting practice and training. The first time the use of an unmanned aerial system was in 1849, when hot air balloons loaded with explosives began to be used in the war. The prevailing winds swept the balloons to the target area, where they fell and released the payload. Later, the Americans reverse-engineered this technology and developed their Pulsejet-powered unmanned aerial drones, such as the TD2D-1 Katydid and the Curtiss KD2C.
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without a pilot, crew, or human passengers on board. These unmanned military drones, called Ruston Proctor Aerial Target, used a radio guidance system developed by British engineer Archibald Low.
