Project history

First submarine boat of the Italian Navy, obviously experimental. Designed by Eng Inspector Giacinto Pullino, she was known also as Delfino-Pullino or Pullino for short. The dates of her construction are not certain. In official sources she was built between 1892 and 1895, but others say she was laid down in autumn 1889, launched in 1890 (or 1892) and completed 1892. First sea trials may have been made on 29 April 1892 and she may have been commissioned on 1 April 1895, but official sources say 1896 (no day). This uncertainty may be explained by Delfino's experimental construction. To the original electric motor (with 3 propellers, two of which had vertical axis, for diving and surfacing) a petrol motor was added during the rebuilding of 1902-04, for surface navigation; her turret was enlarged and 1-450mm TT replaced the 350mm TT.
