The VDS-100 is a low frequency, variable depth, active sonar system used on surface ships to detect, localize, and prosecute all types of submarines. It has been designed for small ships operating in shallow water against modern diesel electric submarine threats. The VDS-100 uses proven technology from L-3 Ocean Systems‘ HELRAS helicopter dipping sonar and is Elbit Systems’ Helicopter Long-Range Active Sonar (HELRAS) dipping sonar has successfully performed a sea acceptance test (SAT) with the Israeli Navy on board the Seagull unmanned surface vessel (USV).

al data. L3 says that the AQS-18A has 80% commonality with the Helicopter Long Range Active Sonar (HELRAS) DS-100, the main difference lying in the ‘wet end’ transducer systems. This commonality, says the company, enables navies with both large and small helicopters to combine the two sonar types in bistatic or multistatic op In a Sea Acceptance Test (SAT) performed by the Israeli Navy, a Helicopter Long-Range Active Sonar (HELRAS) dipping sonar was successfully converted for operation onboard the Seagull, Elbit Systems’ Unmanned Surface Vessel (USV).

The AQS-18 (V)-5 is a helicopter-borne dipping sonar system used for anti-submarine warfare. It employs long pulses and a high source level to provide long-range detection of underwater targets from a hovering helicopter. Digital signal processing and an adaptive processor sonar increase detection capabilities in shallow, reverberation-limited waters while eliminating false alarms.

The AQS-13 systems are all primarily active sonar transmitting in the upper end of the medium frequency sonar range. These systems offered the additional capabilities of voice communication, bathythermography and rudimentary passive sonar. Helicopter borne active sonar has significant advantages over other sensors and is especially effective in the inner zone where noise from In a trial performed by the Israeli Navy, a Helicopter Long-Range Active Sonar (HELRAS) dipping sonar was successfully converted for operation onboard the Seagull, Elbit Systems’ Unmanned Surface Vessel (USV). NATO forces deployed the Seagull USV during a Joint Anti-Submarine Warfare exercise with The Helicopter Long-Range Active Sonar (HELRAS) DS-100 has been demonstrated to be the highest-performance helicopter dipping sonar in the world.

Dipping Sonars a Key Tool in Hunting Submarines

The Helicopter Long-Range Active Sonar (HELRAS) DS-100 has been demonstrated to be the highest-performance helicopter dipping sonar in the world. The Eurocopter, later Airbus Helicopters AS565 Panther is the military version of the Eurocopter AS365 military version of the Dauphin medium-weight multi-purpose twin-engine helicopter. The Panther is used for a wide range of military roles, including combat assault, fire support, anti-submarine warfare, anti-surface warfare, search and rescue, and medical evacuation.

The long-range active scanning sonar employs a transducer lowered The DS-100 Helicopter Long-Range Active Sonar (HELRAS) was designed as helicopter-operated dipping sonar and modified with Elbit Systems for operation from USVs. As a ship your best option is to try to pick up that attack as soon as possible, evade the incoming fish, and counterattack with your helicopter or long range ASW weapon. Whether to go active or passive sonar is a good question, and I’m really not sure.

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.

Additionally, L3Harris also produces a Helicopter Long-Range Active Sonar (HELRAS) which provides operators with a significantly more capable, interoperable and versatile weapon system that reduces total operating costs by minimizing the time needed to execute an Anti-Submarine Warfare (ASW) mission.

Abstract Helicopter Long Range Active Sonar (HELRAS) is deployed from navy helicopters to detect subma-rines. Its worldwide use by NATO navies is expected to increase due to the increasing need to detect sub-marines at greater distances. The 1.33 to 1.43 kHz signals vary in spectrum and duration depending on the circumstances. HELRAS sonar may affect the The AN/AQS-18 developed from the AN/AQS-13 and is a helicopter-borne, long-range, active, dipping sonar.
