There were two periscopes. The forward one, used to attack, was produced by San Giorgio, while the aft one, used for exploration, was produced by the firm Galileo. Typical of Italian submarines, the periscope sleeves extended considerably from the cunning tower and were enclosed in a light metal structure quite visible from a distance. On the TRITONE the periscopes reflected the German style cunning tower and were completely recessed. Both the exploration and attack periscopes were accessed from the control room and their wells went down all the way to the keel.
