CONTRALTO-S®
Anti-torpedo countermeasures system for submarines
The CONTRALTO-S® system – a new-generation solution – provides submarines with effective protection against all light- and heavyweight torpedoes, as validated by sea trials. It is a system fully integrated in the combat management system (CMS) that proposes an evasive maneuver to the carrier and triggers the launch of CANTO® munitions.CANTO® is a wide-spectrum jammer installed on French submarines. It has been designed to satisfy the need to decoy and jam torpedoes fitted with acoustic heads, and to do so throughout the frequency spectrum and irrespective of the mode used by the torpedo’s sonar (passive or active). Its role is to deflect the threat while cloaking the submarine to allow it to take evasive action.
