I think that the 5900t cruiser is the better of the studies....


;)

BPs of this ship are made by annual steel + steel from BB Cuzco scrapp + steel from Antofagasta & LaPaz bows scrapp.
Engines are comming from BBsAntofagasta & LaPaz
38600shp & 8 boilers - 1906 techno.

That give 12650t & 38600shp (max)

Flattery is appreciated, but I think the ship needs to be faster - at least up around 26-27 knots if it is to have any chance of catching its intended prey.

Now, she can work with other Peruvian 27kts cruisers
