Ship project history: 42 torpedo boats of Improved Spica class have been ordered in 1942 for compensation of heavy losses of escort ships at escorting of convoys to Africa with supply for Rommel corps and Italian army in Tripolitania. Ships of "improved" class differed from a prototype by more powerful machinery and lower endurance. Number of 100mm guns also was shrunk from three to two, but at the expense of usage of triple TTs the torpedo salvo was increased. Besides, they had significantly strengthened antiaircraft armament. Under the design it was supposed to install on each ship 14 AA MGs (1 twin 37mm/54, 2 twin and 8 single 20mm/65), however because of shortage of 37mm MGs new torpedo boats have not received these guns.
Owing to escalating of problems with supply only 16 ships from 42 ordered were laid down, and till September, 1943 only lead Ariete was commissioned, remaining 15 incomplete ships came into German hands.
Modernizations: None.
