53-65K torpedo

Also known as
  • 53-65
  • 53-65K
  • Type 53-65K
  • 53/65K
  • Izdeliye 243

The 53-65K is a Soviet 533 mm wake-homing anti-ship torpedo from the Type 53-65 family. It replaced the peroxide-fueled family propulsion with a kerosene-oxygen turbine, carried a roughly 307 kg high-explosive warhead, and appears in documented torpedo fits for Soviet and Russian submarines including Delta III, Kilo, Akula, and Victor III classes.

Variants

Type 53-65 designations separate the original peroxide-fueled Soviet anti-ship torpedo family from the safer kerosene-oxygen 53-65K branch and later export or refurbished versions.

Wake-Homing Design Context

The 53-65K is best read as an anti-surface torpedo rather than a general undersea weapon. Its wake-homing seeker follows the disturbance left by a ship, and the kerosene-oxygen power plant separated it from the peroxide-fueled Type 53-65 and 53-65M line.

FeatureSourced context
Target setWeaponsystems.net identifies the family as intended for surface vessels, with the 53-65K using active acoustic wake homing.
Fuel choiceThe 53-65K branch used kerosene-oxygen propulsion, trading some range against the peroxide-fueled family members for a safer handling path.
Catalog roleRussianShips armament lists show the torpedo in 533 mm submarine tube fits, while the absence of direct conflict-use evidence keeps this record relationship-only.
Timeline

53-65K torpedo Key Events

  1. Type 53-65 enters service

    NavWeaps and Weaponsystems.net list 1965 for the original Type 53-65 family member, establishing the baseline Soviet wake-homing anti-surface torpedo line.

    Sources: Type 53-65 - Weaponsystems.net, Russian Torpedoes after World War II - NavWeaps

  2. 53-65K and 53-65M appear

    Both NavWeaps and Weaponsystems.net list 1969 for the 53-65K and 53-65M variants; the 53-65K branch used kerosene-oxygen propulsion rather than the family's peroxide fuel path.

  3. 53-65KE export variant introduced

    Weaponsystems.net identifies the 53-65KE as the export version of the 53-65K and places its introduction in 1984.

The class introduced a MIRV-capable Soviet SSBN design, remained visible in Russian Pacific Fleet strategic exercises into the 2010s, and ended regular SSBN service when K-44 Ryazan was withdrawn after the other Project 667BDR boats had already left service.
