This time about rebuilds...and for a very particular case.

I have an old AC, 7000 tons displacement (light). I plan to strip all weapons from it, armor it as much as I can, cut some of it's machinery away, and use it as a target ship.

Well, I planned to until I saw the costs. With all the armor I plan to put on her, and with armor tonnage/1000 BP and $ costs... it will be as expensive as a whole new ship of her size...

I found a reference to that old dutch PDs rebuilt as target ship... and I read about concrete being used as armor on it...but I don't know how effective it will be, how much it will cost...etc etc etc, you get where I am heading to
So the question is...first...
-when you rebuild a ship the BP and $ cost of armor is taking the whole armor tonnage in account and dividing it by 1000?. Or by doing (new armor-previous armor)/1000

-what's the deal with concrete as armor?. How do I sim it?. How much it costs?...

thanks in advance :) again :D

This is the key section...

QuoteDistribution of weights at normal displacement:
   Armament: 226 tons, 2.7 %
   Armour: 1,920 tons, 23.1 %
      - Belts: 1,199 tons, 14.4 %
      - Torpedo bulkhead: 0 tons, 0.0 %
      - Armament: 396 tons, 4.8 %
      - Armour Deck: 254 tons, 3.0 %
      - Conning Tower: 71 tons, 0.9 %
   Machinery: 2,758 tons, 33.2 %
   Hull, fittings & equipment: 2,072 tons, 24.9 %
   Fuel, ammunition & stores: 1,312 tons, 15.8 %
   Miscellaneous weights: 30 tons, 0.4 %

So do a new SS with the changes.  Then to get the cost note the change in armor weight; that is your new armor for the target ship. 

You pay BP cost = (tonnage/1000); $ cost is equal to BP cost.

Note the change to your machinery and other weights as you remove the engines, etc you can scrap those to recover 15%.  I would suggest you keep the guns as coast defense mounts.

Plus there is the 20% cost in money only (no BP) for the Refurbishment.

Yep, that I already did. But I don't know if it's the (tonnage after reconstruction-tonnage prior to reconstruction)/1000 or (tonnage of armor, period)/1000.

The guns I'm keeping, indeed.

Part of the operation is a massive increase in deck armor. So, it's reconstruction (25% in $, 10% BP aswell).

And I'm still interested in the part about using concrete as armor as the dutch did...may make the costs less bad. But I don't know the costs of putting concrete as armor, or how to sim it...

You pay the difference between the new and old armor amounts.

Before the changes the armor weighed 1,920 tons or 1.92 BP / $.  If you increased the armor to 3,500 tons then you would pay 3,500 (new) - 1,920 (old) = 1,580 / 1000 = 1.58 plus the reconstruction cost.

got it, thanks mike :)


Now there's just one question left...anyone can tell me about the concrete armor?

Which one? Garibaldi and Pueyrredon are Greek, San Martin and Belgrano are scrap? They were the only 7,000t cruisers in La Marina. Or did you get Pueyrredon back from Greece?
