Service history
Folgore was built at the Regio Cantiere di Castellammare di Stabia. She was launched on 29 September 1886 and was completed on 16 February 1887. On 10 June, the annual fleet maneuvers began; Folgore was assigned to the "defending squadron", along with the ironclads,,, and, the protected cruiser, and several smaller vessels. The first half of the maneuvers tested the ability to attack and defend the Strait of Messina, and concluded in time for a fleet review by King Umberto I on the 21st. The second phase consisted of joint maneuvers with the Italian Army; Folgore and the torpedo cruiser were tasked with blockading Livorno. The exercises lasted until 30 July. The following year, she took part in the annual fleet maneuvers, along with five ironclads, a protected cruiser, the torpedo cruisers Tripoli,, and, and numerous smaller vessels. The maneuvers consisted of close-order drills and a simulated attack on and defense of La Spezia. Later that year, the ship was present during a naval review held for the German Kaiser Wilhelm II during a visit to Italy. The ship's career was cut short on 5 July 1889, when she collided with the protected cruiser while the two ships were steaming off Capri. Folgore was badly damaged, and she could not be restored to her original capabilities. She was accordingly :wikt:laid up|laid up. Folgore was briefly recommissioned to take part in the annual fleet maneuvers in 1894, along with her sister shipSaetta. After two months in service, both vessels returned to the reserve. As of 1895, she was located in La Spezia, along with Saetta. That year, unrest in the Ottoman Empire that killed hundreds of foreign nationals prompted several of the European great powers to send an international fleet to pressure the Ottomans into compensating the victims. In November, a small Italian squadron was sent to Smyrna to join the fleet in there; Folgore was mobilized as part of a larger force in Naples that consisted of the ironclads Francesco Morosini,, and, the protected cruiser, the torpedo cruiser, and five torpedo boats. This second squadron was stocked with coal and ammunition in the event that it would need to reinforce the squadron at Smryna. She remained in reserve until 12 April 1900, when the Regia Marina sold the ship for scrap. Folgore was thereafter broken up.
