Built as the MS-31, this vessel was launched on June 18, 1942, and was swiftly completed and commissioned into the 2nd Squadron on June 24, 1942. It was promptly deployed to the Strait of Sicily, where it engaged in several operations against the British Navy. Among its notable endeavours was its involvement in the Battle of Mid-August (Operation Pedestal), as well as a successful ambush south of Ra’s Muşţafá where it sank a British ship. Following the Italian armistice in 1943, the vessel joined the Italian Co-Belligerent Navy and took part in special missions, including the renowned operation that involved rescuing British saboteurs in Fano, where it destroyed an enemy train. In 1957, the vessel underwent modernization, with the installation of a more powerful engine and the replacement of its two 20 mm Breda cannons with two 40 mm Bofors guns. It was subsequently renamed MS-473. During this period, the ship primarily engaged in training exercises and coastal control duties. On December 1, 1974, it was decommissioned in Taranto and subsequently transferred to Venice, where it is now on display at the Venice Nautical History Museum.

Introduced in Update "Starfighters", the MS-473 is equipped with two single Bofors 40 mm guns, which are highly effective against most naval and aerial targets. As additional armament, it carries 8 depth charges; although they prove to be somewhat impractical, in close encounters with a naval target, they can be used to inflict significant damage or destroy the enemy vessel outright. The manoeuvrability and speed of the ship are sufficient, allowing for evasion of enemy attacks. In terms of survivability, it is comparable to other ships of the CRDA 60(t) class.
