Sonobuoy

A sonobuoy -short for sonar-buoy- is a relatively small expendable sonar system that is dropped from military aircraft performing anti-submarine warfare. The buoys are ejected from aircraft in canisters and deploy upon water impact. An infatable surface float with a radio transmitter rises to the surface for communication with the aircraft, while hydrophone(s) sensors and stabilizing equipment descend below the surface to a depth that is variable depending on environmental conditions and the search pattern. The buoy relays acoustic information from its hydrophone(s) via radio frequency to operators onboard the aircraft.
