Improved Exeter

This 5 turreted Exeter Heavy Cruiser in fact a design that developed the Surrey class Heavy Cruiser. The design started as a 5 turreted York class but with reduced armour to maintain speed and able to carry this many turrets. There were two turret layouts, this one and another where the 3rd turret placed just behind the 2nd funnel, giving a ship somewhat Iron Duke class look.
