Built as MS-11, the boat was launched on January 31, 1942, and completed and commissioned on April 29, 1942. It was deployed to North Africa on September 3, 1942, where it operated alongside MS-15. Their mission was to transport a squadron of Guastatori (combat engineers) of the San Marco Regiment from Marsa Matruk to a location near the port of Alexandria. They also conducted anti-submarine surveillance and naval ambush operations with other units. Following the Armistice of Italy on September 8, 1943, MS-11 became part of the 1st Motor Torpedo Squadron stationed in Leros. However, on September 26, 1943, it suffered severe damage from a German air attack. To prevent it from sinking, the crew intentionally ran the boat aground on the beach. After World War II, MS-11 underwent modernization and conversion into a motor gunboat equipped with six 20 mm positions and renamed as MV-611 (MV stands for Moto Vedetta, in english patrol boat). From 1958, it was deployed in Magdalena for cadet training until it was replaced by MS-444 in 1964. MV-611 was ultimately decommissioned on May 1, 1965.

Introduced in Update "Starfighters", the MV-611 is a motor gunboat armed with six 20 mm Breda guns. It is capable of inflicting significant damage to enemy coastal vessels. However, it should be noted that the MV-611 is vulnerable to enemy strikes due to its CRDA 60(t) hull, which is not particularly armoured. Nevertheless, the boat offers good speed and manoeuvrability. The best strategy for operating these boats is to flank the enemy and avoid head-on engagements.
