of the war, Conte di Cavour was scrapped, and Giulio Cesare was surrendered to the Soviet Union. Renamed Novorossiysk, she was ultimately sunk in October 1955 by an old German mine left over from World War II. Her wreck was later salvaged in 1957 and broken up thereafter. Andrea Doria class Vice Admiral Giuseppe Valsecchi was responsible for the next battleship design, the Andrea Doria class. The class comprised two vessels—Andrea Doria and Duilio—and the design was based on the previous Conte di Cavour with minor modifications. These two ships were ordered in response to the French . As with the Conte di Cavours, the two Andrea Doria-class battleships were significantly modernized in the late 1930s along similar lines: the central turret was removed, the propulsion system was completely replaced with more efficient machinery, and the secondary battery was replaced with new turret-mounted guns. The two ships entered service in 1916, and were based in Taranto with the rest of the main fleet for the duration of World War I. Both ships were involved in the Corfu incident in 1923. The ships' modernization work was completed after Italy entered World War II. Duilio was damaged at the Battle of Taranto, while Andrea Doria was not hit. Both ships were present at the First Battle of Sirte, though only Andrea Doria engaged British forces. The two ships survived the war, and were the only battleships the Allies permitted Italy to retain after the conclusion of hostilities. They served in the Italian Navy for another decade until they were discarded in the mid-1950s. Francesco Caracciolo class The next Italian battleship design represented a major qualitative step forward. The design was prepared by Rear Admiral Edgardo Ferrati, and was intended to match the latest foreign battleships, such as the British . The new ships were to be armed with a main battery of eight guns and had a top speed of , much faster than any contemporary design. The Francesco Caracciolo class was ordered in 1914; the lead ship was laid down that year, and the other three vessels were laid down in 1915. After Italy entered World War I in May 1915, work slowed dramatically, as resources were diverted to more pressing needs. Work on the ships stopped completely by March 1916, and the three ships begun in 1915 were scrapped shortly after the end of the war. In 1919, the Italian
