SS Iberia, Liner

[miketr]

What do people think of this ship?  4.63 BP and $4.63 (its rough as I know I need to pay full cost for the guns / armor; and those are only for war time configuration)

A lot cheaper and more usefull than the fuelhogs Magnificent and Mercury. 

France would contemplate buying this design, but will ask to put in a Turbo electric propulsion.

[P3D]

I'd suggest to have longer range. Liners are supposed to steam at full speed all the way long. Although 4200nm is the distance between Rio and Seville.

Does anyone have TE drives?  If such and some turbines can be worked out we can talk a deal if you want.  Just want the design or would the Transatlantique Line want a ship or two built in Iberian yards?

I'd suggest to have longer range. Liners are supposed to steam at full speed all the way long. Although 4200nm is the distance between Rio and Seville.

What type of range, would you suggest as by dropping the speed to 18 knots her range increases by 50%.  I could punch the 21 knot range to 5,000 by dropping the misc displacement to 9500 tons.

France and the UNK has developed T E drive, especialy for the superliners.

[Walter]

What are you expecting along the way that requires this ship's 150mm guns to have 500 shells per barrel?

[Tanthalas]

Italia also has TE drive however we developed it for our BB program

[P3D]

5000nm@21 range would be better. That would be adequate to reach the Philippines after recoaling at Aden or Masqat.
I think even direct-drive turbines would work fine, as the ship would rarely go slow. Or mixed turbine-VTE (on a third shaft) if the designer are concerned with low speed coal consumption.

Hopefully nothing as I hope I wouldn't be so desperate as to use her as an AMC; I just put the number in.  In her civilian role she wouldn't be armed and as a troop ship would be under escort.

[Borys]

Ahoj!
I'm fairly sure that the Baltikum has TE drives.

Updated design... for a little more range and a few 100 less rounds of ammo.
