I've been fiddling around with my proposed refit for the Dristigheten II Class Battlecruisers starting in 1934, this refit has a full 130mm DP outfit as it's main secondary armament as a replacement for the 8-5.9inch guns in 4 turrets. The shells for the main guns are also upgraded to heavier 825kg ones.

Don't you mean "partial reconstruction" at 50% cost, not a refit at 25% cost?

The Bulging, new engines, extra armour, new turret machinery, new secondary armament all denote this.

Quite similar to the reconstruction of RN Cristoforto Columbo overall. Just not quite as capable.

I did mean a partial reconstruction

Any comments?

She got fat, right? ;o)

Seriously, have you tried to actually decrease her size? Of course this would make sense only if you can use the tonnaged freed this way.

For my South Africa I managed to improve speed, armor and armament but she lost about 1,500ts of weight (see encyclopedia section).

However, our designs are quite different and I´m not sure if something similar is possible for your BCs.

It don't work, without bulges I can't pour nearly enough armour onto the hull.

Well she is a battlecruiser, not a battleship. So throwing that much armor on her, while wise, might not be what would be needed.

IIRC a battlecruiser is a capital ship that traded armor for speed compared to a battleship. Well, from this point of view South Africa is the BC and Dristigheten a battleship because South Africa will be faster than her Nordmarkian comrad.... :o)

That depends: that was the British definition of a BC. The German definition was more like a ship that trades gun power for speed vs a battleship.

Yeah, but Nordmarks BC has a much heavier broadside than her South African cousin.... hehehe

For a 1914 BC she has good speed (equal to the Kongo of that time). Her belt armor is a bit thin, but not too much. I'm assuming her deck was vastly increased. Of course, reducing armor for speed and firepower in considered normal by British standards, even if she's not sacrificing as much armor as say the original BCs or Glorious.

Actually the true British battlecruiser traded gun power for speed.

Splendid Cats vs. Iron Dukes
Hood vs. large QE designs with 8x18" guns
G3 vs. N3
Vanguard vs. Lion

Of course, Vanguard was a "fully-armoured battlecruiser"

You probably don't need all that armour. Fitting 10 duple 130mm mounts and the light AA will give you problems. I tried with Columbo but gave up and went back to 8 mounts because there was no way 10 would fit.

With a proposed reconstruction of Caracciolo in 1935 I wondered what would happen with using all the 5000tons allowed. Ended up with massively too much armour.

Removing the bulges and reducing armour to the levels already set by the Gota Lejon class rebuild, she just isn't strong enough. Any ideas?

Bulges, completely new TDS and more power to maintain speed. Armour is more or less as good as you can get it.

I think your BCs simply don´t offer the potential some other rebuilds did. It´s probably not possible to get an entirely satisfactoring "new" fast capital ship based on those hull.

To me it seems as if your battlelines speed is about 27kn. So why bother increasing their speed at all?

I´d probably give up the term BC and high speeds and just use the saved weight from a newer 27kn-machinery to put some thicker plates on them, combined with a modern secondary/AAA equipement.

Not sure if this is worth considering for you.

TDS added, speed actually increased, bow slightly rebuilt, misc weight increased, and we well balanced ship.

Doesn´t look too bad to me. Her armor is still relatively weak - not sure how many of those lately-build super-ACs or mini-BCs are around in your projected combat zones. Some of those new small capital ships feature guns that can pose a real threat to your ships vitals.

The number of 37mm and 20mm guns seems excessive. There´s probably a small chance for further weight savings. Especially the 37mm guns have quite a heavy shield for such a small gun.

Historically most shields used for guns in deck mounts were there to protect the crew from blast and spray. Splinter proof shields would have made the mounts to heavy - in case of light fast-firing guns it would render the installation useless as you can´t follow planes closing in any more.

Have you considered cutting away her conning tower to save even more weight?

Her range also is excessive. There might be another chance to save some weight which can than be distributed elsewhere.

This is very true, but I can't really afford to replace these ships with new builds, though it is possible.

Those sheilds are rather heavy. The number of AA guns is influenced by the capability of these ships to operate in the baltic.

The range is out of Nordmarks wanting to run fast mentality, and is the best way of reducing the displacement of the ship.

If your fleet speed is 27 knots you might as well leave the newer ships at 27 knots unless you need that extra knot for something.

Also maybe you should set your cruising speed for a lot faster is you intend your ships to run at higher speeds. Be interesting to see a ship with its cruising speed the same as her max speed, and see what range she gets after that.
