Research of the creation and development of unmanned aerial vehicles

Drones were created back in the USSR. Many believe that UAVs - unmanned aerial vehicles, otherwise known as drones, appeared only at the beginning of the 21st century. However, this is not the case: since the 60s of the last centuries, Soviet and American engineers have been building supersonic unmanned reconnaissance aircraft for the armies of their countries. In addition, drones are actively used for environmental purposes. They are called "eco-drones". They are no different from ordinary ones, the prefix is designed to emphasize their purely peaceful, scientific purpose.
