Sonobuoys have become essential equipment in military and naval operations to conduct anti-submarine warfare and underwater acoustic research
A sonobuoy is a small, inflatable buoy - usually 13 cm (5 inches) wide and 90 cm (3 feet) long that is tossed/ejected from ships or aircraft conducting underwater acoustic research, hunting for fish and other sea life. It is used for many applications in the water. Sonobuoys are generally used as a temporary platform to conduct experiments, such as studying the behavior of sea animals underwater, searching through the ocean for clues to the ocean's topography, gathering data on how the waves move, and other details. They are also used in military applications such as sonar tracking, electronic warfare, acoustic telemetry, and anti-mine applications. The sonobuoy is primarily used as a research tool, not as a full-fledged defense tool. There are two main types of sonobuoys namely afloat and inflatable. The most popular type of buoy used by the military is the buoyancy buoyant sonobuoy, which works just like an inflatable boat and is ejected from an aircraft for testing in the w
