Royal Navy 1902

IMO,

2T1x234 & 19kts = poor 1902 AC

=> 2T2x234 & 21kts are better

I used the historic Orlando-class as a template, so 1886 design versus my 1902 design.  I pondered making it larger but I want it to replace Powerful-class LPCs while being half the cost.

The type strikes me as not being up to a fight with other armored cruisers, but your sense of priorities may differ.

[Kaiser Kirk]

Compared to historical designs, it's in line. Plus the brits tended to go for fewer heavy guns.
Folks should remember that at this time the ability of the big guns to penetrate and explode was minimal, and they were widely seen as close-in finishers something like torpedoes.  The Oregon's performance and then the Russo-Japanese battles helped change that, as did advances in shell design. The expectation was the QF shell guns would turn the ship into a shell torn wreck, likely on fire, mobility killed by flooding and holes in the stack, smoke and flame making guns unworkable.  Then the big guns would finish off.

So..compared to my Marco Polos, she's more heavily armed. Compared to the Garibaldis, less.  But the Garibaldis are 50% bigger.

Historic Orlando class is not adapted to our sim (obsolet design).

2T2x... & 21kts are used by many fleets in our sim.

If you are hurting for BP as much as the armor plate tenders indicate, then this is a squandering of a pressious resource.

No, built stronger & better cruisers could be made on 4,5 or 6 HY.
That's just HY adjustment.

I wasn't really planning on building this specific class, I'm using it as my starting point.  I'm hurting for BP now but once my Formidable-class battleships are finished I'm probably going to be all set.  Relatively speaking of course

     a normal bow and a cruiser stern
   Block coefficient (normal/deep): 0.583 / 0.594
   Length to Beam Ratio: 10.09 : 1
   'Natural speed' for length: 21.31 kts
   Power going to wave formation at top speed: 30 %
   Trim (Max stability = 0, Max steadiness = 100): 50
   Bow angle (Positive = bow angles forward): 0.00 degrees
   Stern overhang: 0.00 ft / 0.00 m
   Freeboard (% = length of deck as a percentage of waterline length):
            Fore end,    Aft end
      - Forecastle:   20.00 %,  22.00 ft / 6.71 m,  22.00 ft / 6.71 m
      - Forward deck:   30.00 %,  14.00 ft / 4.27 m,  14.00 ft / 4.27 m
      - Aft deck:   35.00 %,  14.00 ft / 4.27 m,  14.00 ft / 4.27 m
      - Quarter deck:   15.00 %,  22.00 ft / 6.71 m,  22.00 ft / 6.71 m
      - Average freeboard:      16.80 ft / 5.12 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 88.5 %
      - Above water (accommodation/working, high = better): 91.4 %
   Waterplane Area: 14,708 Square feet or 1,366 Square metres
   Displacement factor (Displacement / loading): 136 %
   Structure weight / hull surface area: 65 lbs/sq ft or 319 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0.94
      - Longitudinal: 1.68
      - Overall: 1.00
   Caution: Poor stability - excessive risk of capsizing
   Hull space for machinery, storage, compartmentation is adequate
   Room for accommodation and workspaces is adequate
   Ship has slow, easy roll, a good, steady gun platform
   Excellent seaboat, comfortable, rides out heavy weather easily

I've noticed for some time that you designate space for short and long range wireless, whereas I expect to refit my ships with same.
Marconi managed a 66nm transmission in 1899, but no actual long range until 1902, and all those were with shore stations.
I wouldn't think the Royal Navy would be planning to incorporate a very very new technology that was still rapidly evolving until it
had a better feels for the space parameters needed, 1902-3ish.  And yes, I realize the latest vessels are lay down 1902, but..

We said 1900 was the cutoff date for wireless sets. A rather clean date that does not bend things to far.
