In military aviation, what does UAV stand for?

UAV stands for Unmanned Aerial Vehicle, which accurately describes a type of aircraft that operates without a human pilot onboard. This technology allows for remote operation or autonomous flight capabilities, making UAVs essential in various military applications, such as reconnaissance, surveillance, and tactical support. They can gather intelligence without risking human lives and can be deployed in environments that may be too dangerous or difficult for manned aircraft. The use of UAVs has significantly transformed modern warfare by increasing operational efficiency and reducing the risks associated with manned missions.

The other options do not correctly define UAV; for example, "Universal Airborne Vessel" suggests a broad and less precise term, while "Underwater Aerial Vehicle" and "Unified Aircraft Vision" diverge from the established terminology and concepts associated with unmanned aerial systems.
