Design
Construction and commissioning
F7 was laid down by FIAT-San Giorgio at La Spezia, Italy, on 1 July 1915. She was launched on 23 December 1916 and commissioned on 19 March 1917.[1][2][3][4]
Service history

F7 was assigned to operations in the Adriatic Campaign of World War I. Initially stationed at Brindisi, she was transferred to the northern Adriatic Sea in January 1918, where she operated alternately from Venice and Porto Corsini.[1][5]
On 12 February 1918, F7 sank the 245-gross register ton steamer Pelagosa — which was operating as an Austro-Hungarian Navy auxiliary warship and antisubmarine patrol vessel — near Grujica Island (known to the Italians as Guizza Rock). She also sank the passenger-cargo ship SS Euterpe near Pag on 11 August 1918.[1][5]
Off Point Mika on 29 August 1918, F7 fired a torpedo at a submarine and later at a steamer. In both cases, the torpedo malfunctioned and missed its target.[1][5]
F7 also undertook minefield reconnaissance missions in the waters of the Maknare Channel (known to the Italians as the Passo delle Sette Bocche). During one of these she attacked a steamer about 3 nautical miles (5.6 km; 3.5 mi) from Škarda, but malfunctions in F7′s torpedo-firing mechanism prevented her from hitting the ship.[1][5]
World War I ended in November 1918. After it ended, F7 served under the Venice naval command until April 1919. She then was stationed at Naples until 1923. In October 1925, she was transferred to the Submarine Division at Taranto. Throughout the postwar period, she participated in maneuvers, attack exercises, and torpedo-firing drills.[1][5]
F7 was decommissioned and stricken from the navy list on 1 February 1929. She subsequently was scrapped.[1][2][3][4][5]
