The MAS.15 Italian Navy Torpedo-armed Motorboat

The limited basin of the Adriatic Sea favoured the operation of the light ships and various types of “microorganisms”. The Italian naval command at the end of 1914 already drew attention to the combat capabilities of motor torpedo boats. The design of such a unit was presented in November, 1914, by the Italian company Maccia Marchini. The cutter had a displacement of 7–8 tons, a length of 15 meters and was propelled by two engines, 200 HP each. It was supposed to reach a speed of 30 knots. The armament was two torpedoes dropped from both sides. However, the Italian Navy decided not to work with a small and not very well-known company.

The fate of the project proposed in February, 1915, by the Venetian company SVAN (Società Veneziana Automobili Nautiche – Venetian Society of Self-Propelled Sea Boats) was different. Torpedo boat designed by engineer Atillia Bisio was somewhat reminiscent of the design of the Maccia Marchini company. It had a similar displacement (7.8 tons) and a length of 15 meters. The drive consisted of four engines with a power of 100 HP each, working on two propeller shafts. The armament was limited to two 450 mm torpedoes and one 37 mm gun.
