Napoli B
In the course of naval cooperation between Italy and the U.S.S.R., ship projects were prepared under Soviet orders. Among them was a battlecruiser with a standard displacement of 22,000 tons. It was supposed to have a speed of 35–37 knots, nine 250 mm guns in three turrets, and a 220 mm main armor belt.
