Otaria was one of five Glauco-class submarines built for the Regia Marina (Royal Italian Navy) during the early 1900s. The boat served in World War I and ceased service in 1918.

Construction and career

Otaria was laid down on 10 May 1905 at the Regio Arsenale at Venice, launched on 25 March 1908 and completed on 1 July 1908.[1] She was employed as a training ship in the Tyrrhenian Sea.[2]

After an intensive training,[2] in August 1914 the submarine was assigned to the 4th submarines squadron based in Venice[3] and put under the command of Lieutenant Emanuele Ponzio.[4] At the start of the First World War for Italy the ship was re-assigned to the 1st submarines squadron based in the Adriatic Sea and was employed as a defensive unit in the Gulf of Venice.[2]

In June 1916 Otaria was deployed in Taranto, forming a separate unit combined with the twin submarine Glauco[5] and later on January 1917 he was transferred again in Venice and assigned to the 2nd submarines squadron.[6]

In December of the same year the submarine was transferred in Porto Corsini and later in 1918 disarmed and demolished.[5]

Throughout the war, the Otaria had carried out a total of 46 defensive missions.[2][5]
