How long Littorio-class battleships might serve after 1945

If surviving Littorio-class battleships were returned intact to Italy, how long could they last in Cold War service?

Perhaps another thirty years with refits, but wartime damage and Allied restrictions would determine which hulls were available and worth sustaining.

An intact Littorio-class battleship might provide another thirty years of service if Italy funded refits. Mediterranean operations underpin that estimate, though the surviving ships would begin with different repair histories. Roma had been sunk by Fritz X, and another sister had suffered serious damage at Taranto before returning to service. Completing Impero would also require resources Italy lacked after the war and Allied acceptance considered unlikely in this scenario.
