To replace her aging and obsolete "battleships" Chile would like to purchase a coastal defense battleship.  Emphasis on armor and firepower.  Prefer fewer larger guns.  Size range: 5,-8,000 tons.  Chile would like to purchase two or three, depending on cost.

I have two designs. The first is already in IRN service, the second is being considered for IRN service. The 1900 design isn't so much an improvement as a different design philosophy, it trades range for increased armor and armament.

To replace her aging and obsolete "battleships" Chile would like to purchase a coastal defense battleship.  Emphasis on armor and firepower.  Prefer fewer larger guns.  Size range: 5,-8,000 tons.  Chile would like to purchase two or three, depending on cost.
Most of my "Kongo II" designs should be appropriate.

And since you specifically request armor and firepower:

Fore River shipyard would also submit it's design from the Congo competition, if the desire were for a smaller vessel:

What kind of range do the Chileans need? I'm going to revise my coastal battleship designs as they likely have too much range.

probably 3 to 4 thousand miles.  Enough to cruise the Chilean coast.  Its an inherently defensive vessel but with sufficient collier support it could possibly strike the Brazilian coast.  Most certainly the Argentinean coast.  Another thing I'd like to know is can those offering designs also build the vessels?  I know that some now have building obligations for other nations, I just want to be sure that if one of these designs is chosen it can be laid down in the beginning of 1901.

Here are my three minimalist designs. The 10 inch guns is actually comparable to the 11 inch gun both in real and as they are being used in game, so the smaller ships are by no means underarmed.

Another thing I'd like to know is can those offering designs also build the vessels?  I know that some now have building obligations for other nations, I just want to be sure that if one of these designs is chosen it can be laid down in the beginning of 1901.
As long as you don't want a dozed or so it's not a problem. I wouldn't be taking part if I didn't want to get the contract, or I wouldn't call them 'German export'.
