OVERVIEW: The SET-65E Enot is a heavyweight, electric-powered, submarine-launched torpedo developed by the Soviet Union for export in anti-submarine warfare roles. It employs active/passive acoustic homing and is fired from standard 533 mm submarine tubes.

DETAILS: "SET" stands for "Samonavodyashchayasya Elektrotorpeda" (self-guided electric torpedo), "65" refers to the year of design inception, and "E" denotes the export variant. The SET-65E is the export version of the SET-65, adapted for submarine launch and improved over the previous SET-53 family with greater range, deeper operating depths, and a more advanced seeker. It uses a silver-zinc battery for electric propulsion and is capable of tracking underwater targets in both open-ocean and littoral conditions. The SET-65E maintained compatibility with 533 mm tubes and featured more sophisticated electronics for better counter-countermeasure resistance.

Under NATO designation ET-80A[67], the SET-65E offered Soviet allies a significant performance upgrade over earlier export torpedoes. It included reliability improvements, better hydrodynamics, and longer engagement capability while maintaining simplicity in logistics for export customers.

TYPE: Heavyweight Anti-Submarine Guided Torpedo

FUNCTION: The torpedo is launched from 533 mm submarine tubes and uses an active/passive sonar seeker to detect, track, and home in on enemy submarines. It is designed for medium-range ASW engagements, offering improved performance in both deep and coastal waters.
