The Italian: Folgore class was a pair of torpedo cruisers built for the Italian Italian: [[Regia Marina]] (Royal Navy) in the 1880s. The two ships - and - were designed by Benedetto Brin during a period of experimentation with the theories of the French: [[Jeune École]] in the 1880s. The vessels were armed with three 14inches torpedo tubes, and they had a top speed of 17kn. Both ships' careers were uneventful, and they spent most of their time in service conducting training exercises. Italian: Folgore was seriously damaged in a collision in 1889, and was thereafter reduced to reserve status, as the damage could not be completely repaired. She was eventually sold for scrapping in 1900, while Italian: Saetta served as a gunnery training ship from 1897 to 1908, when she too was dismantled.
Italian: Folgore and Italian: Saetta were designed by Benedetto Brin; Brin had previously designed several classes of very large ironclad battleships, including the and es, but by the 1880s, he had begun to embrace the ideas of the French: [[Jeune École]], which emphasized small, fast, torpedo-armed vessels that could damage or destroy the much larger battleships at a fraction of the cost. After the two Italian: Folgores, which were rated as Italian: torpediniere-avisos (torpedo-avisos), the eight ships of the were laid down, continuing Brin's ideas at the time.
The ships of the Italian: Folgore class were 56.7m (186feet) long overall and had a beam of 6.31m (20.7feet). Italian: Folgore displaced 364LT normally, while Italian: Saetta displaced 394LT. Italian: Folgore had an average draft of 2.15m (07.05feet), while Italian: Saetta sat slightly lower in the water as a result of her greater displacement, with a draft of 2.27m (07.45feet). Their hulls were constructed from steel and featured a pronounced ram bow. The ships had a crew of between 57 and 70 that varied in size over the course of their careers.
Her propulsion system consisted of a pair of horizontal double-expansion steam engines manufactured by Hawthorn Leslie and Co., each driving a single screw propeller. Steam for the engines was supplied by four coal-fired locomotive boilers that were trunked into a single funnel amidships. In 1892, Italian: Saetta was re-boilered with oil-fired models for experimentation purposes. Italian: Folgore could steam at a speed of 17kn from 2150ihp, while Italian: Saetta reached the same speed from 2130ihp. The ships had a coal storage capacity of 60MT.
The primary armament for the Italian: Folgore class was three 14inches torpedo tubes. They also carried a small gun armament for defense against torpedo boats, consisting of two 57mm 43-caliber (cal.) guns, two 47mm guns and four 37mm 25-cal. guns, all mounted singly. The ships carried no armor protection.

After entering service, both vessels were assigned to the main Italian fleet. They were primarily occupied with annual training exercises, along with occasional fleet reviews for monarchs, including one for the King of Italy, Umberto I in 1887 and German Emperor Wilhelm II in 1888. In 1889, Italian: Folgore was badly damaged in a collision with the protected cruiser and could not be repaired to her original condition. As a result, she spent most of the rest of her career in reserve.
For much of the 1890s, Italian: Saetta was frequently reduced to reserve, in part to reduce maintenance on the vessel. Italian: Folgore made a temporary return to active service in 1895, when she joined Italian: Saetta for the annual maneuvers. In 1897, she was withdrawn from front-line service and employed with the gunnery school; her gun armament was accordingly increased in 1902 to provide a variety of weapons for gunnery trainees to practice operating. In the meantime, Italian: Folgore was stricken from the naval register in 1900 and broken up for scrap. Italian: Saetta continued in her service with the gunnery school until 1908, when she too was broken up.
