The UMGT-1ME torpedo is designed to destroy submerged and surfaced submarines. A hydroacoustic active/passive homing system guides the torpedo onto a manoeuvring target irrespective of the target’s noise level.

The homing system controls the torpedo’s course, depth, and roll parameters, provides its manoeuvring in two planes, and guides the torpedo to the proximity fuse activation area or directly onto the target. The torpedo's modular design facilitates its maintenance. A practice version is available for training purposes. The UMGT-1ME torpedo is designed for arming ASW aircraft and helicopters with internal suspension (in weapon bays).
