Service

Both boats were built by CRDA in its Trieste shipyard. The submarines had initially been ordered in 1931, but were acquired by the Italians when Portugal cancelled the order. Both boats were launched in 1935, and they saw action in the Spanish Civil War and the Second World War. ''Glauco'' was badly damaged by the British destroyer HMS ''Wishart'''' ''and scuttled by her own crew on 27 June 1941, west of Gibraltar; ''Otaria'' was surrendered to the Allies in 1943 and used for training until it was sent to the junkyard in 1948.
