Torpedoes are armed with surface ships , submarines and naval aviation . In the USSR Navy, torpedoes are classified depending on the warhead charge — nuclear or conventional, by the type of power plant — combined-cycle (thermal), electric or reactive, and conventional or small-sized according to their mass and size characteristics.

Design History
The SET-40 torpedo was created at the NII-400 (now the Central Research Institute "Gidropribor") under the leadership of chief designer V. I. Senderikhin. A homing device with an active-passive acoustic system was developed under the guidance of chief designer Yu. B. Naumov.
In 1962, the SET-40 torpedo entered service with the USSR Navy and was successfully used by surface ships and submarines . [2]
Design
The SET-40 torpedo had a cigar-shaped shape divided into 4 main compartments:
- Instrument compartment
- Combat charging compartment;
- Battery compartment
- The tail part.
An acoustic active-passive homing system was installed in the instrument compartment.
In the combat loading compartment of the torpedo there was a non-contact acoustic fuse , an igniter and an explosive .
A silver-zinc rechargeable battery of type M3-2 was placed in the battery compartment.
In the rear part there was a power plant and mechanisms controlling the movement of the torpedo , a propeller and four feathers with vertical and horizontal rudders for controlling the torpedo in direction and depth. [one]
Principle of Operation
Before a torpedo shot, using the torpedo fire control device (PTS), the calculated parameters of the target's movement were introduced into it. After the torpedo exited the torpedo tube and launched the direct current electric motor, the torpedo developed a speed of 29 knots and rushed towards the target. During the movement, the electric torpedo did not leave a visible trace, which ensured the stealth of the attack. If for some reason a torpedo began to deviate from a given direction, then the heading device acted on an electro-hydraulic steering machine that controls vertical rudders and directed the torpedo at a given course . If the torpedo began to deviate from the set depth, then the changed pressure of the external water acted on the depth machine, which transmitted the corresponding force to the electro-hydraulic steering machine controlling the horizontal rudders and the torpedo returned to the set depth of travel. When a torpedo exits into the range of homing equipment , its active-passive sonar system carried out sonar target submarine and controlled the rudders, providing a torpedo exit to the target. As soon as a torpedo entered the zone of operation of a non-contact acoustic fuse, the fuse circuit was closed and the explosive ignited, causing an explosion in warhead charge and damage to the target.

Modifications
- SET-40 - the basic model of the torpedo adopted for service in 1962 .
- SET-40U is an advanced modification with an improved battery and the new Sapphire SSN. Adopted in 1966 .
