Assuming I were inclined to fight the ship, I'd stand off at a distance where I can penetrate your deck armor and you can't reciprocate.

Assuming I weren't inclined to fight the ship, I'd just mosey on by.  Even my semi-dreadnoughts are speedy in comparison.

Can't comment on the music, as I don't do Youtube.

The thing is I think firanji should have at lest one round ship for tradition may be a transport or some sort of carrier later on

On the music it's the theme to the magic round about

Round ships are cool, but you should be more modest with them if you build them. The advantage of a round ship is that is allows for maximum displacement on minimum draft. If too deep the wave resistance makes the form far too cost-inefficient. So if you want a round battleship aim for about ¼ the size, with a single turret at the centre, sort of a classic flying saucer.

As for the refit/rebuild of the original ships; I would recommend a minimal refit were the addition of fire control and perhaps a switch to oil as the only major changes. The Justice-class is still quite fast and there is nothing wrong with their protection (however a more extensive armour scheme would have been nice, but the thick deck compensates somewhat).

21,5kts, is still a decent speed, it is faster them most Dutch, Swiss and DKB 2nd line capital ships, and her big guns can still do harm to most of the cruisers (from light to battle) in the pacific.

oil fired actual range 9050nm

Miscellaneous weights: 300 tons
25t big radio*
25t flagstuff*
250t firecon

*+best guess for what was fitted

and here be the cost
   bp      $
   13.151   13151   13.151

Refurbishment      2.6302
remove bunkerage   -250   -0.125
add fire con 0.25   250   0.25
costs   0.25      2.7552

so any errors glaring mistakes and the like?

P3D

Don't have the negative "remove bunkerage" item, make it zero (cost of 1.25BP/$2.88).

Otherwise fine. You might want to change from coal-firing to oil (how much the range would be with the same bunkerage of oil), but your range is still OK - and you might have fuel availability issues.

after losseing 250 t the range with oil fireing is 9050 nm
it was just above the Miscellaneous weights breakdown
