Krait Defence System

SEA delivers a flexible, scalable, modular and small footprint Anti-Submarine Warfare solution with Krait Defence System.

Krait Defence System comprises a family of detection solutions and countermeasures. These use common software that integrates SEA’s proven decoy and torpedo launcher systems with the miniaturised KraitArray, a thin line towed array sonar system.
