OVERVIEW: The 53-56VA is a Soviet export, surface-launched, pattern-running heavyweight torpedo introduced in 1967 for torpedo boats and surface combatants. It uses a programmed zig-zag pattern to engage surface vessels without homing capability.

DETAILS: The designation “53-56VA” refers to a 53 cm diameter torpedo derived from the 1956 base model, with “VA” indicating a modified export variant for surface launch applications. The 53-56VA was a surface-launched counterpart to the submarine-launched 53-56V, modified with launch settings and propulsion start adaptations for use from deck-mounted torpedo tubes. It retained the pattern-running guidance system and was equipped with a contact fuze and a high-explosive warhead. The propulsion used a kerosene-fueled wet-heater engine, giving it short- to medium-range effectiveness in naval surface combat.

TYPE: Heavyweight pattern-running torpedo

FUNCTION: The 53-56VA runs straight for a preset distance after launch before executing a programmed search pattern to sweep for surface targets. Designed for launch from torpedo boats, it was intended to attack enemy surface combatants using contact detonation.
