The spreading out of radio waves is referred to as propagation and is used in which Navy equipment?

The process of radio wave propagation is essential for effective communication systems. In Navy operations, communication equipment utilizes radio waves to send and receive messages over various distances. Understanding radio wave propagation allows naval personnel to optimize communication links, ensuring reliable signal transmission even in challenging environments.

While detection, aircraft, and radar and navigation systems also utilize radio waves, their primary focus differs. Detection mainly involves identifying targets or signals, aircraft systems may use communication as one of several functionalities, and radar and navigation focus more on locating and tracking objects rather than just establishing communication. Thus, communication is the most appropriate category for the described phenomenon of radio wave propagation.
