OVERVIEW: The 53-65 WH is a Soviet surface-launched, wake-homing heavyweight torpedo introduced in 1968. Designed for use against surface ships, it homes in on the wake trail left by a vessel rather than using acoustic or wire guidance.

DETAILS: The designation “53-65 WH” indicates a 53 cm diameter torpedo developed in the mid-1960s, with “65” referring to the model family and “WH” denoting Wake Homing. It was an early surface-launched version of the wake-homing concept, intended for limited deployment aboard Soviet surface combatants. The torpedo employed a thermal (kerosene-oxidizer) propulsion system, a high-explosive warhead, and a passive wake-homing seeker to track and impact the target ship’s wake. Its operational deployment was restricted due to limitations in targeting reliability and shipboard integration.

TYPE: Heavyweight wake-homing torpedo

FUNCTION: The 53-65 WH is launched toward a detected surface ship and uses a passive wake-homing sensor to detect and follow the turbulent water trail left by the ship. It detonates upon impact and was intended to strike the target near the stern for maximum damage.
