Ship project history: In 1939 there are begun studies of the project of small MTB on the basis of pleasure boat. First launches of MTS type (MTS is deciphered as Motoscafi di turismo, siluranti (tourist boat carrying torpedoes)) became development of suicide boats of MTM type. The project was developed by Baglietto. The sizes were increased for placing of two torpedoes and two crew members. MTS launches have passed successful trials in 1940, however because of insignificant endurance and low speed (with torpedoes speed felt to 23kts) and did not participate in operations.

In 1941 Baglietto developed the advanced project of small MTB of MTSM type (last M means modified) in which have tried to remove the basic lacks of previous model: low seaworthiness and low speed. The number of carried torpedoes was shrank to one. Some launches instead of a torpedo could carry up to three frogmen.

Launches of MTSMA type were a little increased, in comparison with MTSM type. The endurance was increased. 100 launches were ordered in 1943, a part of incomplete launches was captured by Germans in September, 1943.
