Sister ship of Vittorio Veneto-class battleship. For its size, it had powerful artillery, reliable catapult plane capacity and good anti-torpedo protection, but it was poorly protected from air strikes.
Roma's 381mm gun has the highest penetration among all existing 15-inch gun in game (including the one on Richelieu). And the rotation speed of the turret is at 6°/sec.
HE and AP shells bear different characteristics (AP shell weighs 60 kg more), and the muzzle velocity is different as well.
She uses the same Damage Control Party as the one on Japanese battleship. It activates for 10 seconds only.

Let me get this right; the Littorio class guns had the longest range of ANY capital ship main battery weapons, and the Roma is going to have a pathetic 18 km shooting range?! If this is true, this ship will be "Roma" in name only.
But this "Roma" is actually a pretty fun ship to play with fast turning turrent and a good concealment. You can solve the range problem with your spotting Aircraft.
