The CAPTAS-4 system comprises a UMS-4249 ultra-low-frequency active sonar with four ceramic rings, integrated into a towed variable-immersion body. [2] [3] Capable of diving up to 300 meters (980 ft), it covers a very large volume of water over an extremely long range. In addition to the UMS-4249 variable depth sonar, a towed multi-functional ...
AN/SQS-26 was a United States Navy surface ship, bow mounted, low frequency, active/passive sonar developed by the Naval Underwater Sound Laboratory [1] and built by General Electric and the EDO Corporation. At one point, it was installed on 87 [2] US Navy warships from the 1960s to the 1990s and may still be in use on ships transferred to ...
SURTASS LFA is a long-range, all-weather, sonar system with both passive and active components, operating in the low frequency (LF) band (100–500 hertz [Hz]). USNS Impeccable has the original LFA system, weighing 155 tonnes; the 64-tonne Compact LFA derivative was developed for the smaller Victorious class.
Bow-mounted spherical SONAR data gathering set with Low Frequency Active Interference Rejection, Dual Towed Array Processing, and Full Spectrum Processing: Los Angeles-class submarine, Ohio-class submarine: IBM: AN/BQQ-6: Hull-mounted, long-range passive SONAR system adopted from the AN/BQQ-5: Ohio-class submarine [103]
The S2087 is a Low Frequency Active Sonar (LFAS) and consists of both active and passive sonar arrays. Thales describes the system as "a towed-array that enables Type 23 frigates to hunt the latest submarines at considerable distances and locate them beyond the range at which they [submarines] can launch an attack".

AN/SLQ-32(V)2 – Initially the most common variant, the (V)2 expanded on the (V)1's capabilities with new receiving antennas for increased radio frequency coverage. It added the ability to detect high frequency targeting and fire-control radars, providing early warning against an imminent anti-ship missile attack. [4]
SURTASS passive and active low frequency sonar arrays USNS Impeccable (T-AGOS-23) is an Impeccable -class ocean surveillance ship acquired by the U.S. Navy in 2001 and assigned to Military Sealift Command 's Special Missions Program .
It provides the operator 180 degrees of selectable coverage via electronic switching of sonar stave arrays circling the towed body. The newest AN/SQQ-32(V)4 upgrade contracted in 2011 includes a high frequency wide band (HFWB) modification that greatly improves shallow-water minehunting capabilities in high clutter environments.
