On the night of 10–11 November, the British Mediterranean Fleet launched an air raid on the harbor in Taranto. Twenty-one Swordfish torpedo bombers launched from the aircraft carrier attacked the Italian fleet in two waves. The Italian base was defended by twenty-one 90 mm anti-aircraft guns and dozens of smaller 37 mm and 20 mm guns, along with twenty-seven barrage balloons. The defenders did not possess radar, however, and so were caught by surprise when the Swordfish arrived. The first wave struck at 20:35, followed by the second about an hour later. "Vittorio Veneto" was undamaged in the attack, but three other battleships were hit, two of which were severely damaged. The morning after the Taranto raid, "Vittorio Veneto" led the Italian fleet to Naples. There, she took over the role of fleet flagship, under the command of Admiral Inigo Campioni.
