Which of the following statements is FALSE regarding the subsets of Undersea Warfare?

The statement that only passive sonar systems are used is inaccurate. In undersea warfare, both passive and active sonar systems play vital roles. Passive sonar involves listening for sounds made by submarines or other vessels without emitting any signals, making it stealthy and effective for detection. However, active sonar sends out sound waves and listens for their echoes to determine the location and characteristics of targets, which can provide more precise and timely information about underwater threats.

The nature of undersea warfare requires a combination of both active and passive systems to enhance situational awareness and ensure effective operational capabilities. Utilizing only passive systems would limit the effectiveness and responsiveness in various scenarios, demonstrating why this statement is considered false.
