Sorry Weneto have misunderstood your post, Google translate sometimes playing tricks on me and these are approximate translations into French. To return to Di Giussano it was a great unit, but the lightness of its armor will be fatal, as everyone in his class also. I think they wanted to imitate the French ships which at the time formed part of the fastest ships, but at the expense of the shield, what you think.
Friendly Fred
Very good vid of the “Vittorio veneto” battleship showing in detail the armor and antiaircraft armament. According to the narrator the 381mm turrets could fire every 50 seconds and the guns had a range of 35 km.
As I wrote, it’s exactly these. Italy has a traditional foe the French Navy, and with restricted resources for ship building, it chosen to follow the same tactic, rely on high speed to avoid gunfire and close the distance while over-sized guns destroy quickly the French boats.
