The Pacinotti class consisted of two submarines launched in 1916 for the Royal Italian Navy (Regia Marina): Pacinotti and Guglielmotti. Both submarines served in World War I.[1][unreliable source?][2][unreliable source?] Gugliemotti was lost in a friendly fire incident with a British warship. Pacinotti spent the war defending Italian shipping around Italy. Following the war Pacinotti was discarded.

Construction and career
editThe Regia Marina (the Royal Italian Navy) placed an order for the two submarines in 1913 from the Società FIAT-San Giorgio, Muggiano, La Spezia while SM U-42 (later renamed Balilla) was being built.[3]
The Pacinotti launched on 13 March 1916 and the Gugliemotti launched on 4 June 1916.[2][unreliable source?][3][4] The Gugliemotti, while on its maiden voyage, was mistaken for a German U-boat by HMS Cyclamen northwest of Capraia on 10 March 1917 where it was sunk by both gunfire and ramming.[5][1][unreliable source?][2][unreliable source?] The Pacinotti operated in the Tyrrhenian Sea, defending trade routes, for a total of 13 missions between 24 March 1917 and 4 September 1917. It was then deployed to Sicily on 7 September 1917, undertaking anti-submarine patrols along with the 300 GRT Malamocco, which acted as bait for enemy submarines. The Pacinotti returned for maintenance at La Spezia on 20 December 1917, and was used for training from February 1919 to 4 June 1919 at La Maddalena. It was stricken from the list of active ships on 15 May 1921.[1][unreliable source?][2][unreliable source?][3]
