OVERVIEW: The SET-65M Enot-2 is a heavyweight, ship-launched, electrically propelled anti-submarine torpedo developed by the Soviet Union. It is an improved version of the SET-65 family, designed for enhanced underwater performance and guidance accuracy.

DETAILS: "SET" stands for "Samonavodyashchayasya Elektrotorpeda" (self-guided electric torpedo), and "65M" refers to a modernized version of the original 1965 design; "Enot-2" is the development name, while NATO designated it ET-80A[76]. The SET-65M was introduced in the early 1970s to replace aging models like the SET-53, featuring a more sophisticated active/passive acoustic homing system, greater operational depth, and higher reliability. It used a silver-zinc battery for propulsion and could be launched from 533 mm ship-mounted torpedo tubes. The system was part of a broader modernization push within the Soviet Navy to equip surface combatants with more capable ASW weapons.

TYPE: Heavyweight Anti-Submarine Guided Torpedo

FUNCTION: The SET-65M is deployed from 533 mm torpedo launchers aboard surface warships and uses its onboard active/passive sonar seeker to acquire and home in on submerged submarines. It is optimized for anti-submarine warfare in both deep and shallow water zones, especially under conditions of thermal layering or acoustic interference.
