The Interactive Defense and Attack System for Submarines would allow submerged submarines to engage threats from the air, naval vessels and coastal targets.
The Turkish company Roketsan will be responsible for development, qualification and series production of the IDAS warhead and support testing of its control actuation system.
Roketsan will also participate in system-level design activities and share in the series production of the CAS.
"IDAS provides new self-defense and asymmetric warfare capabilities." Diehl Defense said. "The submarine can launch the multi-role missile from a torpedo tube under water by means of a launching container. Aided by an innovative fiber-optic data link, the operator in the submarine is capable of controlling the missile during the entire flight offering the opportunity of target change, correction of the target impact point or mission abort.
"The system can also be refitted into existing submarines with minor effort."
The IDAS consortium aims to test a verified product by next year for firings from a submerged submarine.
The agreement was signed late last week at the IDEF International Defense Industry Fair in Istanbul.
