"Vittorio Veneto" saw extensive service during the war. Early in the war, she participated in the Battle of Cape Spartivento in November 1940 and the Battle of Cape Matapan in March 1941. While damaged by torpedoes several times, including in the engagement off Cape Matapan and by the British submarine in December 1941, the ship escaped undamaged during the British raid on Taranto in November 1940. She spent 1941 and early 1942 attempting to attack British convoys to Malta, but crippling fuel shortages in the Italian fleet curtailed activity thereafter. "Vittorio Veneto" was among the Italian ships that were surrendered to the Allies in September 1943 after Italy withdrew from the war, and she spent the following three years under British control in Egypt. After the war, she was allocated as a war prize to Britain and subsequently broken up for scrap.
