This ship is just an exercise for me. In reality it makes more sense to acquire the Poseidon and put this design on the shelf until the resources for it are available. This should be the last change to the design. Changed the turrets to follow Swamphen advise. From a coastal battleship it has turned into a fast light battleship. Faster than anything the Peruvians have and the older Iberian designs, their main advantages are the 14" guns and their speed. Thanks to all for your inputs and guidance.

The remaining concern I would have is the range: 3,000 miles at 10 knots is VERY short-legged, you're probably looking at 6-700 miles at full speed.

Thanks again. Changed to 8950 miles, the maximum before putting too much stress on the hull. Should be the last one change, seriously.

If she is really for coastal defense, then she doesn't need very long legs. Just enough to get from port to port and yet make a reasonable patrol when needed. The ships that will be the eyes of this ship would be the patrol boats, torpedo boats, sub chasers, destroyers, or even a cruiser or two.

I'm assuming Columbia only has up to type 2 slips and docks. This would mean the ship would have to be less than 555 feet long so that it can be serviced locally, rather than having to send it to Atlantis or elsewhere ever time you need some work done on her, or you need to clean the hull a bit.

It started as a coastal and turned into a pocket battleship. I'm happy with this final design. Faster than anything close by and armed with main guns that measure up to the Peruvian, Chilenian and older Iberian designs. Thanks to all for your help in guiding me along. In reality it doesn't make sense to build if the Atlanteans sell the Poseidon to Colombia but is a nice design to keep on the shelf if resources are available.

I was looking around. Poseidon is 625 feet long, so if you want to work on it domestically, you'll need a Type 3 drydock.

You'll probably want the twin 4.5s to be superfiring (a Bs-Xs secondary arrangement over A-Y mains), but otherwise looks pretty decent. Agree Poseidon might be a better deal, though.

Never underestimate the ambition of a banana republic. ^_^

Colombia has 2 Type 2 drydocks, so it would need to expand 1 of them. That could be done by devoting 2 of it's factories to the work for a year, or both Type 2s could be upgraded in a single year if that's all the factories did.

Peru was lucky it didn't have to do this, since Huascar fits (barely) into a Type 2 drydock.

I think is being taken care of already. Check the second quarter for Colombia in 1932.

Speaking of Huascar, wonder if the Chileans will give her the same rousing welcome they gave Lima...

That will depend greatly on how busy the Chileans are when Huascar arrives. And also what ships are avalible when she finally does arrive near South American waters. How knows. Chile might provide an escort to prevent piracy....Harlock is looking for a new ship to replace the Arcadia after all.

To be fair, the museum Huascar is considered a tomb for Admiral Miguel Grau. (honestly she's suppose to be being used as a submarine tender right now, but I'll overlook that considering what she is and what she is in our time).
