 Both ships escorted convoys to North Africa in late 1941, including Operation M42, where "Andrea Doria" saw action at the inconclusive First Battle of Sirte on 17 December.Fuel shortages curtailed further activities in 1942 and 1943, and both ships were interned at Malta following Italy's surrender in September 1943.Italy was permitted to retain both battleships after the war, and they alternated as fleet flagship until the early 1950s, when they were removed from active service.
