DSIT Solutions Ltd. (DSIT) – one of the world’s pioneers in underwater defense and security solutions based on advanced sonar and acoustics technologies for naval missions – recently launched its SwordFish^™ Towed Array Sonar (TAS) system. Towed by the vessel, the SwordFish^™ complements DSIT’s BlackFish^™ HMS (Hull Mounted Sonar) system for use at various sea depths and for different mission types. When used close to the shoreline as a standalone solution, all DSIT’s sonar systems can be operated via one onshore control station.

DSIT’s Fish^™ anti-submarine warfare (ASW) family is capable of underwater target search, detection, tracking and classification in passive, active and parallel modes. Each sonar system includes machine learning technologies for automation algorithms, reducing operator workload and required expertise.

Designed to operate with the medium frequency of both the BlackFish^™ HMS and Bow Mounted Sonar (BMS) in littoral and deep-water ASW operations, the low-frequency SwordFish TAS is the latest solution to join the family. The SwordFish TAS system is connected to the vessel’s stern via a light winch, the cable length of which is determined according to the mission type and requirements. The lightweight TAS system, with its low deck signature, is suitable for Frigates, Corvettes, OPVs of various sizes, and even small vessels such as Fast Patrol Crafts (FPC).

“We identified the operational need to locate and track submarines at various depths and in different mission environments, including when using small vessels for either offshore or green waters missions,” says Hanan Marom, VP Business Development & Marketing of DSIT.

Among the other defensive solutions DSIT manufactures are the SeaShield^™ Underwater Coastal Surveillance System, a long-range underwater passive and active detection system warning against underwater and above water targets including submarines, semi-submersible vehicles and surface ships; AquaShield^™, an advanced Diver Detection Sonar (DDS) system; and PointShield^™, a portable and/or stationary PDDS for medium-range ship or asset protection.
