This is my anachronistic 3rd Class Battleship Warrior

Yes, this is the anachronistic design of a ship that uses the displacement and dimensions of the original British ironclad, the Warrior. The length allows the ship to have a slightly higher speed than might otherwise be the case. I toyed with the idea of using 10in guns for the main armament, but settled for the 9.2in guns, instead. There are also 8-6in QF, 12-4in QF, and 8-6pdr QF guns. The armour basis is just 8in. This is the Springsharp report:
