What does the acronym DICASS stand for?

The acronym DICASS stands for Directional Command Active Sonobuoy System. This system is specifically designed for anti-submarine warfare (ASW) and plays a critical role in detecting submarine activity during naval operations. DICASS sonobuoys are deployed from aircraft or ships and use active sonar to transmit signals that can help locate and track submarines.

This equipment operates by sending out sound waves and analyzing the returning echoes, which allows naval forces to gain valuable information about submarine movements and positions. The directional aspect of the system enhances the precision of detection, making it an effective tool for maritime situational awareness and threat assessment.

In the context of the other options, they do not accurately represent the established nomenclature or intended function of the system related to sonar and anti-submarine applications.
