Peru Fleet in Navalism

[Jefgte]

As I wrote, I am also in Navalism Forum.
This forum is an alternate history about a new map of the world.
I have in charge Peru Fleet. Peru is a medium power with a potential to built 8000t of ship by year.
We can built personnal Never Were warships & buy update techno, year after year.
I have begin to built in 1897 & we are today in mid 1912.
About History, it smell powder between Iberia & Turkish...

All Guys use SpringSharp for Warships studies, easy to use & fast enough to built a fleet.

Well, I am going to present some Jef's studies about the Peru fleet.

Peru, near Gran Colombian, is a medium-small industrial country.
she could built in 15 years 6 battleships, 6 cruisers, some torpedo boats & guns ships.

I have imagined the 1st div of Battleships with 6 Torpedo Boats & 2 Gun Boats in Chimbote Bay in 1901.

2 x Battleships:
1897-1899-10400tl-12000tfl-2T2x305+12x152+8x76.2-18kts
Cuzco
Lima

6 x Torpedo Boats:
1897-1898-250tl-313tfl-3x76.2+2TLTx457-21kts
Mancora
Punta Sal
Tacna
Paracas
Ilo
Huacho

2 x Gun Boats:
1897-150tl-175tfl-1x76.2+2x50.8-12.8kts
Serena
Moropa







(This is not a Pearl Harbour photo...) 


The Gun Boats Serena & Moropa are at the entrance of the bay

Hi Jef,

great job  but i think, your fleet need some cruisers.

A very interesting design, indeed, my friend!

What makes me guessing a little ... has there beed a predecessor with diagonal turret arrangement, and four turbines/shafts; or do I read the springsharp listing wrongly-?
And - please do give the reasons for mirroring the forward superstructure completely to the aft - redundancy?

In any case, I am eager for the outer lines, too!

(Frage: gabs Vorläufer mit diagonal versetzten Türmen und 4 Tu auf 4 Wellen, oder worauf bezieht sich die Tabelle;
Gründe für die Komplettspiegelung der Aufbauten vorne <=> achtern? Bitte Außenansichten!)

Ciao,
Harold

[Jefgte]

There is a mistake in that SS 

All 34cm turrets are in centerline position
-----------
2 blocks of superstructures (bridges) with 2 command positions symetrical for better chance in action.
Disposition of the turrets
AY
AQY
APQY
APQXY

I adopt that styl for the Peruvian Navy.
I like very much the position of the PQ turrets with the turbines under the guns & the 2 blocks of superstructures.

AC Shinchi Roca -1913 - 8000t - 3T2x23cm-AQY had also that look...

Built a fleet with the classic ABXY, BX superfiring is not original.

Salut Jean-Francois!
Never mind - springsharp is not the holy grail.
But -as I mentioned before- could we see the outlines of your design? And, if you don't mind, would you accept some critics on it?
Ciao,
Harold

[Jefgte]

I accept all critics & suggests from the Master in conception & calculation.

Like all warships built for Peru, Waskhar use "fresh water bulkhead" to refresh magazines.
That's necessary for tropical climat.
