Rafael Introduces Torbuster - 4th Generation Hard-Kill
Torpedo Countermeasure
|
Rafael Advanced Defense Systems
Ltd. unveiled a 4th generation torpedo decoy called Torbuster.
The new decoy combines both acoustic countermeasures and hard
kill, targeting enemy torpedos fired at a submarine. Rafael
introduced the development of a 4th generation decoy last autumn,
at the Subcon conference, but officially unveiled the product
at the Pacific 2008 exhibition in Sydney, Australia.
Torbuster is designed to protect submarines from attacks
by all types of acoustic homing torpedoes. Upon detection
of an incoming torpedo, the submarine launches a the decoy
from an external launcher. The decoy will propel itself to
a safe distance from the submarine and seduce the incoming
torpedo by transmitting acoustic signals using reactive acoustic
deception. This technique was first implemented with Rafael's
second generation decoy called Scutter,
which was optimized for operation in deep sea and littoral
water. Unlike earlier passive decoys, Torbuster actively engages
the torpedo as it closes in, activating an explosive warhead
when the target is at the closest proximity, inflicting sufficient
damage to the torpedo to neutralize it.
