Project history

Very similar to the ex-U42 ordered by the German Navy, but this class had 3 bow TT, the only Italian class of submarines so armed, excepted the 'CC' class laid down in 1943.

Modernizations

None.

Naval service

Guglielmotti, during her maiden voyage, was mistaken for a U-boat by the British sloop Cyclamen, NW of Capraia Is, and sunk by gunfire and ramming 10.3.1917. Although fast and rather good, her sister boat was stricken less than 3 years after the war ended, and the class was not repeated.
