Communication and radio

On the "Bragadin" the radio equipment consisted of a 3 kW short-wave radio set (utilizing tubes). The antenna consisted of a stay and cables running forward and aft almost the full length of the boat. The radio room was installed in the control room.

Hydrophones

There was a hydrophone system connected to transmitters mounted on the hull.

The Bragadin first war patrol, under the command of Bandino Bandini, began on June 24th
with the transport of 27 tons of war materiel for the Italian Air Force from Naples to Tobruk.

General announcing system

All "Bragadin" were equipped with an announcing system. Each compartment could communicate with a central station located in the control room via a speaker microphone system.

Alarm system

The "Bragadin" were equipped with a klaxon operated from the control room. Upon sounding the alarm, all hatches would be secured and the engineers would commence the diving procedures securing the diesel engines' intake and exhaust valves.

Telephone call system

The "Bragadin" were equipped with two buoys situated on deck and attached to a retrieval system. If necessary, the buoys could be released and floated to the surface, giving surface units a telephone connection to the submarine.
