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 ...
The AN/UQQ-2 Surveillance Towed Array Sensor System (SURTASS), colloquially referred to as the ship's "Tail", is a towed array sonar system of the United States Navy. SURTASS Twin-Line consists of either the long passive SURTASS array or the Twin-line array, consisting of two shorter passive arrays towed side by side.
The CAPTAS-4 is a towed array sonar developed by Thales Underwater Systems to equip first-rank surface combatants.Manufactured in Brest, France, it represents the high-end and most powerful system of the company's CAPTAS (Combined Active and Passive Towed Array Sonar) line of products [1] and equips several first-rank warships of the French Navy as well as those of various export customers.
The submarine hit the warship’s sonar – a piece of equipment being towed hundreds of metres behind it, which was fitted with sensitive hydrophones for listening under water.
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".

The first experimental array was a six-element test array laid at Eleuthera in the Bahamas in 1951, followed, after successful experiments with a target submarine, in 1952 by a fully-functional 1,000 ft (304.8 m), forty-hydrophone array. At that time the order for stations was increased from six to nine.
The Type 093B is a further upgraded version, equipped with a pump-jet propulsor and the ability to deploy a towed sonar array. It is expected to play more of a land-attack role with long-range ...
Sonar 2076 is a submarine sonar detection system designed by Thales for the Royal Navy. The system comprises an integrated suite of active and passive sonar systems including bow, fin, flank and towed arrays. [1] Known components include: Type 2077 Parian obstacle avoidance sonar; Type 2081 environmental monitor; Type 2094 oceanographic sonar
