A total of 27 boats were built by three shipbuilding companies, with the letter after the boat number indicating the manufacturer. There were small variations between manufacturers, mainly in the steam turbines used, and whether they had one or two funnels. The eight boats of the T-group, designated 74 T – 81 T, were built by Stabilimento Tecnico Triestino, located at Triest. The sixteen boats of the F-group, 82 F – 97 F, were built by Ganz-Danubius at their shipyards at Fiume and Porto Re.

The class was considered to be a successful design, and all boats saw extensive active service during World War I, undertaking a range of tasks, including escort duties, shore bombardments, and minesweeping. All survived, although several were damaged by naval mines and collisions. One was torpedoed and badly damaged by a French submarine, and two sank an Italian submarine. All the boats were transferred to the Allies and scrapped at the end of the war, except for four that were allocated to the navy of the newly created Kingdom of Serbs, Croats and Slovenes.

The Novara class was a class of three scout cruisers built for the Austro-Hungarian Navy. Named for the Battle of Novara, the class comprised SMS Saida, SMS Helgoland, and SMS Novara. Construction started on the ships shortly before World War I; Saida and Helgoland were both laid down in 1911, Novara followed in 1912. Two of the three warships were built in the Ganz-Danubius shipyard in Fiume; Saida was built in the Cantiere Navale Triestino shipyard in Monfalcone. The Novara-class ships hold the distinction for being the last cruisers constructed by the Austro-Hungarian Navy.
SMS Admiral Spaun was a scout cruiser built for the Austro-Hungarian Navy. Named for Admiral and Marinekommandant Hermann von Spaun, Admiral Spaun was constructed shortly before World War I. Laid down at the Pola Navy Yard in May 1908, the cruiser was launched in October 1909. Admiral Spaun was commissioned into the Navy just over a year later, in November 1910. The first ship of the Austro-Hungarian Navy to be constructed with steam turbines, her design later influenced the construction of the Novara-class cruisers.
SMS Tátra was the lead ship of her class of six destroyers built for the kaiserliche und königliche Kriegsmarine shortly before the First World War. Completed in 1913, she helped to sink an Italian destroyer during the action off Vieste in May 1915 after Italy declared war on Austria-Hungary. Two months later the ship participated in an unsuccessful attempt to recapture a small island in the Central Adriatic Sea from the Italians. In November and early December Tátra was one of the ships conducting raids off the Albanian coast to interdict the supply lines between Italy and Albania. During the early stages of the 1st Battle of Durazzo in late December, the ship was tasked to tow her one of her sister ships that had been crippled by a mine. She was forced to abandon her sister when the Austro-Hungarians were spotted by a strong force of Allied ships and had to evade their pursuit. Tátra participated in several unsuccessful raids on the Otranto Barrage in 1917. She was transferred to Italy in 1920 in accordance with the peace treaties ending the war and renamed Fasana. The Regia Marina used her for spare parts; she was discarded in 1923 and subsequently scrapped.
