AN/AQS-13 dipping sonar deployed from an SH-3 Sea King. The AN/AQS-13 series was a helicopter dipping sonar system for the United States Navy.These systems were deployed as the primary inner zone anti-submarine warfare (ASW) sensor on aircraft carrier based helicopters for over five decades. [1]
HELRAS or the Helicopter Long Range Active Sonar is a naval helicopter undersea sensor, a dipping sonar (a form of towed array sonar), deployed by helicopters of many naval air forces around the world to detect submarines; it is a form of geophysical MASINT.
AN/AQS-13 dipping sonar deployed from an H-3 Sea King. Helicopters can be used for antisubmarine warfare by deploying fields of active-passive sonobuoys or can operate dipping sonar, such as the AQS-13. Fixed wing aircraft can also deploy sonobuoys and have greater endurance and capacity to deploy them.
Thomson Marconi Sonar or TMS was formed in 1996 by the merger of the sonar systems businesses of French defence electronics specialist Thomson-CSF and British company GEC-Marconi after the payment of a balance by the latter. [1] The new company was 50.1% owned by Thomson-CSF and 49.9% by GEC-Marconi. [2] Denis Ranque was appointed as its CEO ...

AN/AQS-13 Dipping sonar deployed from an H-3 Sea King, an aircraft used by numerous countries and produced in Italy, Japan, and the United Kingdom. Antisubmarine helicopters can carry a "dipping" sonar head at the end of a cable, which the helicopter can raise from or lower into the water.
Multibeam sonar is used to map the ocean floor A multibeam echosounder (MBES) is a type of sonar that is used to map the seabed. It emits acoustic waves in a fan shape beneath its transceiver. The time it takes for the sound waves to reflect off the seabed and return to the receiver is used to calculate the water depth.
A solution is the use of a 'dipping sonar', which in a way is nothing more than a small sonar attached to a long cable. By using this device the Parchim's sonar system was able to search the different water layers. The Parchims were also provided with capable anti-submarine warfare weapons.
