Cruceros Protegido

[The Rock Doctor]

Cesar Class
The Cesar class are just stretched, faster updates of the Saint Thomas class, optimized for escort of the Arquero class armored cruisers.  As the type is also entirely suitable for screening other, slower capital ships, additional units have been ordered.

Zulia and onward feature second generation fire control.
