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.
For example: the M-frigates only carry 16 surface-to-air missiles in the form of the outdated NATO Sea Sparrow (RIM-7). Onboard modern ships the Evolved Sea Sparrow (Block 2 in development) does the job, but those do not fit in the also outdated Mk48 VLS cells on board the M-frigates.
The development of the FIDO (Mk 24 mine) anti-submarine homing torpedo in 1943 (which could be dropped from aircraft) was a significant contributor to the rising number of German sub sinkings. Hedgehog, a 24-"barreled" anti-submarine mortar, mounted on the forecastle of the destroyer HMS Westcott , 28 November 1945.
This made available the required large space in the bow for the BQQ-2 (BQQ-5 as modernized from the late 1970s) sonar sphere, a new and powerful low-frequency detection sensor. Initially armed with Mark 37 torpedoes , by the late 1960s they carried the improved Mark 48 and the nuclear UUM-44 SUBROC short-range anti-submarine missile, replacing ...
The DUBV 43C towed array sonar of La Motte-Picquet.. A towed array sonar is a system of hydrophones towed behind a submarine or a surface ship on a cable. [1] Trailing the hydrophones behind the vessel, on a cable that can be kilometers long, keeps the array's sensors away from the ship's own noise sources, greatly improving its signal-to-noise ratio, and hence the effectiveness of detecting ...
A close-up view of an Alberich tile, illustrating patterns of multiple holes with different diameters. The technology of anechoic tiles was developed by the Kriegsmarine during the Second World War, codenamed Alberich after the invisible guardian dwarf of the Rhinegold treasure from Richard Wagner's Der Ring des Nibelungen music dramas.
