Torpedo Countermeasures . The US Naval Institute News is reporting that the Navy is developing a small torpedo to intercept Russian/Soviet designed torpedoes that are immune to normal acoustic torpedo countermeasures, because they follow the target's wake rather than passively homing on the ship's noise. Unfortunately the Russians use wake-following torpedoes that do not respond to the usual . FIELD OF THE INVENTION. The simplest of the several possible countermeasures to such a torpedo-slowing the target-is suggested by the fact that a ship's sound output increases rapidly with speed. An improved torpedo countermeasure system called the AN/SLQ-61 Lightweight Tow (LWT) Torpedo Defense Mission Module (TDMM) is lighter than the AN/SLQ-25 and has a different tow profile, making it more suited for small combatant warships operating in littoral environments. With the rise of the military submarine after this time, countermeasures were considered for use against them. CANTO® is effective against both active and passive sonar.

The ADC MK 5 is an acoustic torpedo countermeasure with advanced features which can be employed as a static or mobile device and uses Adaptive Countermeasure (ACM) technology. When they are being targeted by a torpedo, they deploy countermeasures that mimic the sounds of a submarine or the return of an active sonar bouncing off of a submarine. Historically speaking, torpedo countermeasures have been a tool used to buy time for a ship or submarine trying to escape an attack, but 21st-century naval technology is changing the way they are used. Our tried-and-tested TCM systems are suitable for any active torpedo defense application. Pakistan became the second country after Indonesia to employ the Zargana, which many experts call superior to its global competitors.
