The last compartment aft, so at the stern, does not have any torpedo tubes. Instead the hydraulic helm system for controlling the rudder and fin, a manual emergency helmstand, a fire extinguishing system (it’s a custom-built system using chemical foam instead of water, because salty water is electro conductive), fresh water tanks as well as a specially noise reduced heating system, which is quite untypical for hunter-killers, are located in this compartment.

This vessel was equipped with a five bladed ship’s propeller. The more blades there are the less noise it causes.
