Done by the superb McPherson, this design takes the I class and removes a turret as well as the torpedoes increasing the armour whilst retaining the speed. The I's could only ever do a 6-gun broadside unless on some very very limited firing arcs and the ahead fire so beloved by Fisher was again, only 6 guns at certain angles. Here you've got 6-guns on a decent platform with better armour and a far tidier layout.
