IDAS (missile)

From Wikipedia, the free encyclopedia

IDAS (Interactive Defence and Attack System for Submarines) is a short-range missile currently being developed for the new Type 212 submarine class of the German Navy.

IDAS (based on the IRIS-T air-to-air missile) is primarily targeted against air threats, such as ASW helicopters, but also against small or medium-sized surface vessels or coastal targets. It is currently being developed by Diehl BGT Defence and HDW, which is a part of Thyssen-Krupp Marine Systems (TKMS), to be fired from Type 212's torpedo tubes. IDAS will be fibre-optic guided and officially has a range of approx. 20 km. Four missiles will fit in one torpedo tube, stored in a revolver magazine. First deliveries of IDAS for the German Navy are scheduled from 2009 on and operational service is planed from 2014 on.^[1]

The IDAS system is also the world's first missile which gives submarines the capability to engage air threats, and the first tube-launched missile that does not emerge in a capsule, but is fired directly from the torpedo tubes.
