[Sachmle]

Not to shabby...hell they're better than my first two classes.

[Korpen]

Here is the second class of BB for Peru

Inti-1903
Manco Capac-1906
Inti class ,Peru BB laid down 1903

Should they not have either engine year 1905 (more likley) or 1900 (there being no 1903 engine tech)?

Their armour scheme intrigues me; their belts are relatively thin, while their deck armour is among the thickest of any ship anywhere.
How come?

[Sachmle]

Looking at the tech list, which is from when Asavery was in charge and could therefore need changed, they first would probably have the 1895 VTE while the second set could have the 1900 turbines, or continue to use the VTE.

Also, shouldn't the 50cals be machine guns, not breech loading?

[Sachmle]

While nowhere near as good as your scratch builts, here's a drawing of Cuzco I made last night. Hope you like it.  :)


Drawing based on images by Wes Wilson

[Jefgte]

 :) :) :)

Nice drawing Sachmle but, I think that funnels are too fat. With slim funnels, the silhouette is better for that period (1900)

Thanks for the comments, I am going to made little modifs.


Jef  ;)

[Blooded]

Nice pic!

The .50s may be elephant guns?  :)

Jef  ;)

I can do slimmer stacks if you want, my main concern in doing it was that the 152mm's barely fit in the citidal, unless the 305mm's are too large, then the superstructure could be lengthened a little.

[P3D]

IMHO 3x340mm and TDS hardly fits into that 78' beam. The turret itself is 30' (assuming the guns cannot be elevated separately), TDS another 20-30', armor 2'. Moreover, the hull is relatively fine, and the machinery+magazine spaces fill up all the 'normal' length nicely, so they must be close to the ends.
And Engine Year should be 1909 not 1908.

[The Rock Doctor]

Yes, it'd be a tight fit. 

The secondary armament's on the light side, I think.  4 x 120 mm guns per side isn't a lot of defence against torpedo-boat attack.

[Borys]

Ahoj!
The most likely enemies are:
- Colombians
- Maoris
- Brandenburgers
- NeoSwiss
- Eorlingas

Are any of these likely to use massed torpedo boat attacks against the Peruvians?

Borys

[The Rock Doctor]

The Swiss, certainly.  GC has the numbers for it.  DKB doesn't have the strength.  Rohan and Maoria prefer heavy artillery.

[Borys]

Ahoj!
Thing is that the Neoswiss have no nearby base to bring those >1000 tonne ships to Peruvian shores.

So that would only leave the Colombians.
True, 4x4,7 ain't much.
8/12x3/4" better.
