24/03/14

submarine boat being set up in the Arsenale of Spezia is given the name Delfino and an eight man's weapons table is established (a commanding vessel lieutenant, a torpedoing non-commissioned officer, a torpedo-boat sub-chief, two torpedo-boat torpedo boats, two electrician torpedo boats and a chosen sailor ).

The unit, which will be of an experimental type, will however be among the first submarines to be equipped with a periscope and a gyroscopic compass and also capable of launching torpedoes both stationary and in motion, arousing great interest in international naval environments.

On the same date, the Dauphin was registered as part of the state ship.
