What is uas and what is the difference between uav and uas

What is UAS?And what is the difference between UAV and UAS?

  • Unmanned Aerial Vehicle - A powered, aerial vehicle that does not carry a human operator, uses aerodynamic forces to provide vehicle lift, can fly autonomously or be piloted remotely, can be expendable or recoverable, and can carry a lethal or nonlethal payload. Ballistic or semiballistic vehicles, cruise missiles, and artillery projectiles are not considered unmanned aerial vehicles.

    • DOD Joint Publication 1-02

  • Unmanned Aerial System – A system comprised of one or more UAVs and the associated Ground Control Station for command, control, and communication and applicable payloads to perform various missions in either the civilian or military environment.


Mission objective

Mission Objective

“The complete mission objectives are for an unmanned, radio controllable aircraft to be launched and transition or continue to autonomous flight, navigate a specified course, use onboard payload sensors to locate and assess a series of man-made objects in a search area prior to returning to the launch point for landing.”
