regained both torpedoes and MS classification. Finally in 1954 they were redesignated one last time, gaining hull numbers MS 471 to 475 and MS 481 to 484. The vessels were at the orders of the COMOS (Comando Siluranti) together with the more numerous ex-American PT boats. At this time the two surviving series 1 CRDAs were upgraded to series 2 specifications, gaining the rear 450 mm torpedo launchers. In 1956 a reconstruction plan was drawn up: seven of the remaining boats were to be transformed into flexible units able to serve as gunboat, torpedo boat or fast mine layer. As a result of budget constraints and plans for equivalent modern, all-metal boats, only four of the motosiluranti were converted by the Baglietto shipyards—MS 472, MS 473, MS 474 and MS 481, the others being decommissioned. Extensive changes were made to the superstructure and hull, including removal of the 533 mm torpedo installations; new radio equipment and a radar were installed. The armament included a Bofors 40 mm gun fore, a second Bofors aft, and twin 450 mm torpedo launchers or naval mines aft. The four converted boats re-entered service between 1959 and 1961, grouped into the 42nd motor torpedo boat flotilla. Two were finally decommissioned in the mid 1970s, the other two at the beginning of the following decade. Nowadays two of the boats are preserved: MS 472 is a monument in Ravenna, while MS 473 is on display in the Ship's Pavilion of the Museo Storico Navale in Venice.
