The MAS 569 was one of the final 4th Series of the MAS Tipo "500". Compared to those of the 3rd Series, it had some minor changes such as the adoption of the manoeuvre rudder on the bridge, the increase of the ammunition supply for the Breda 20 mm/65 autocannon and the addition of support for the Breda 6.5 mm machine gun. MAS 569 participated in the Italian Black Sea Flotilla from August 1942 and arrived on 30 July 1942 in Yalta. In the same year, she was damaged by enemy bombardment. After 1942, she entered service with the German Navy only to be later delivered to the Romanian Navy on 28 August 1943, her fate was to sink somewhere in the Black Sea in August 1944.

Introduced as a premium along with the initial Italian naval tree in Update "Starfighters", the MAS 569 has incredible speed in both Arcade and Realistic and manoeuvrability which allows it to quickly reach enemy targets and launch torpedoes or depth charges. The armament is composed of a single 20 mm cannon and a single 6.5 mm machine gun: the 20 mm can cause quite a bit of damage to enemy boats, however the 6.5 mm has a small magazine and fires too quickly, so it is always worth going out at the right times with the 20 mm to destroy enemy ships with the torpedoes, depth charges, and the 20 mm.
