September 2/19: Denmark The State Department also approved a FMS to Denmark for nine AN/AQS-22 Airborne Low Frequency Sonar (ALFS) systems and six hundred AN/SSQ-36/53/62 Sonobuoys with support for an estimated cost of $200 million. The AN/AQS-22 ALFS dipping sonar and sonobuoy processing system is the primary anti-submarine warfare sensor of US Navy’s MH-60R multi-mission helicopter. It provides mission-critical capabilities, including submarine detection, tracking, localization, classification, acoustic intercept, underwater communication and environmental data collection. The AQS-22 dipping sonar features 4-time greater area coverage than current systems, active or passive sonar modes, active or passive sonobuoys, enhanced shallow water capability, generate high power waveforms and many other advanced characteristics.
