I'd go with a La Argentina type cruiser as well. I thought about a pocket CA myself but it seemed a waste of material for little real firepower.

Myself I've discarded at least twenty cruiser designs, to get the right ship is not easy. Do you go for firepower, armour or speed? Getting the balance right can be hard.

Armour is all that really ensures the survival of your ships in battle. I always try to add a little more than I really need, especially on the decks.

Another try and this is was it comes out. I'm building around 32 knots + as the standard for the fleet so I start by that and play around it. Turn out into another 7000 ton cruiser. Damn it! :-)

Judging by the remaining strength, you can either shrink the ship a bit or lengthen the main belt enough to cover the magazines (probably a wise thing to do).

Argentina offers this design. It may be bigger than you desire but it packs a good punch and with a thick armoured hide too.

I noticed that after I posted it and with only six more feet the magazines were covered. Also increased the number of 88mm to 6 on the side without a noticible difference in weight and hull strength.

Shorten the ship a little bit to drop the tonnage.

Typically we try for a Cross-sectional of 1.00 or an Overall of 1.00 to get the most out of our cruisers and battleships in SS2. Brazil is know for keeping their cross-sectional at around 1.05 for extra strength.

[Hoo-Clone Mode ON] ?!?!?!?!

SWAMPHY!!!!!


;o) However, I agree with you and I guess RA would have too.


perdedor - you probably should decide first what you think Peru really needs and THEN design your ship(s) accordingly. Just playing around with SS won´t help you much.

This is just long term planning because eventually the light cruisers will need to be replaced later in the decade. I'm just using the knowledge of the combined site to try to build the replacements. But in reality you hit it right in the spot. I'm just playing wiht SS. :-)
