OVERVIEW: The SUT Mod 0 is a heavyweight, submarine-launched, wire-guided torpedo developed by Germany for anti-submarine and anti-surface warfare. It is designed for use from 533 mm torpedo tubes and provides dual-role engagement capabilities in deep and littoral waters.

DETAILS: "SUT" stands for Surface and Underwater Target, reflecting its dual-purpose role. The SUT Mod 0 was developed by Atlas Elektronik in the late 1970s and entered service in 1981. It is based on the German DM2 family and features electric propulsion powered by a silver-zinc battery, a passive acoustic seeker, and wire guidance for mid-course control. The torpedo is 533 mm in diameter and designed to be launched from diesel-electric submarines. Its relatively long range and silent electric drive make it suitable for stealthy operations.

TYPE: Heavyweight Dual-Purpose Guided Torpedo

FUNCTION: Launched from 533 mm submarine tubes, the SUT Mod 0 uses wire guidance in the early and mid-course phase, switching to passive acoustic homing to strike enemy submarines or surface ships. It is intended for long-range, silent attacks in both blue water and coastal operational zones.
