Torpedo Launching System (SLT)

Torpedo Launching System – SLT is capable of fire at least 3 torpedoes model MK46 Mod 5 from one triple launchers installed in the two sides of the ships. The system is made up of the following units:

  • Helmsman Unit: monitor that informs to the helmsman about the necessary corrections of the course of the ship, for interception maneuvers as well as for attack of the selected target;
  • Course Indication Unit: Continuously monitor presents course of the ship and the angles of the launchers;
  • Torpedo Control Unit: responsible for the tube selection operation mode, torpedo programming and fi ring command based on a computer solution or determined by manual command;
  • Triple Launchers (port and starboard): two sets of three torpedoes launching tubes.

Helsman Unit

Informs the course error of the launched torpedo. It also has two luminous indicators that command the two phases: INTERCEPT and ATTACK.


Course Indication Unit

It has a dial that informs the ship’s true course as well as an adjustable scale where the required course can be read to enable positioning of the launchers.


Torpedo Control Unit

Provides the features for selection of the launching tube, programming of the parameters for the torpedo, selection of the operation mode and fi ring sequence. The torpedo fi ring commands can be initiated either in AUTOMATIC mode (under control of the ship’s fi re control system) or in MANUAL mode. Whichever fi ring equence that is in progress can be aborted by pressing a key.


Programmable parameters of the torpedo:

Search depth: 80S, 125S, 275, 500, 850 and 1400 feet
Gyro angle: 35°E, 70°E, 0°, 35°D and 70°D
