In cooperation with the ThyssenKrupp Marine Systems shipyard and other industrial partners, Diehl Defence is developing a multi-role capable guided missile providing self-defence capabilities for submerged submarines under the project name IDAS (Interactive Defence & Attack System for Submarines). It is designed to counter threats from the air, naval vessels as well as coastal targets. It can be launched from a torpedo tube engaging targets autonomously by means of an autopilot and infrared seeker. Simultaneously, a fiber-optic link allows data exchange between the missile and the submarine enabling the submarine crew to intervene at any time.
