Italian Submarines
Class "600"

by Cristiano D'Adamo


Controls

When the “600”were on the surface, they operated like any other boat demonstrating good seaworthiness. Maintaining the various ballast tanks full of air provided buoyancy.

 

Rudder

The rudder (semi-compensated) was controlled electrically from the control room, or manually for the aft torpedo room. Also, there was a wheel in the cunning tower in an enclosed wheelhouse. On the “600” the rudder had a total surface of 5.24 m2

The rudder controls ran from the aft torpedo room to the stern over the torpedo
tubes and externally to the pressure hull.

Diving Planes

As standard on most submarines, the “600” were equipped with two sets of diving planes. The forward planes were collapsible (folded upward) for surface navigation and were placed above the waterline; their total surface was 4.97 m2. The aft planes were fixed and placed below the waterline in line with the two propellers and their surface was 3.78 m2. The forward planes were used to control depth, while the aft ones were used to control the angle of the boat. The planes were controlled electrically from the control room, but could also be manually operated from the torpedo rooms.

Anchors

The “600” were equipped with a primary anchor, installed on the port side, and the chain was stored in a well located below the forward torpedo room.
