"DM2A4 Seehecht (export designation \"SeaHake mod 4\" ) is the latest heavyweight torpedo developed by Atlas Elektronik for the German Navy, as a further update of DM2 (Deutsches Modell 2) torpedo which was released in 1976. Being the successor of the DM2A3, it features an advanced electrical propulsion system and a fiber optic cable for torpedo guidance and communication, which, in conjunction with advanced signals processing and mission logic, makes the torpedo largely countermeasure resistant."@en .
