this is correct version. ~0`

Just a few questions regarding the armament - H-58 would suggest to me it's a German warship, the layout looks like a German warship, so I'm just going under the guess it's a German warship, whiffed into a progression of post-WW2 construction, so here's a few thoughts I have on the armaments...


Armament:
9 - 18.11" / 460 mm 45.0 cal guns - 2,995.22lbs / 1,358.61kg shells, 120 per gun
Breech loading guns in turret on barbette mounts, 1937 Model
3 x 3-gun mounts on centreline ends, majority forward
1 raised mount - superfiring

Triple mount 46cm guns - interesting modified layout, like a Super Scharnhorst. Though, the length isn't quite German - they tended to use more than 45 caliber length barrels, and could get away with it - Krupp Steel is notorious for its strength.


6 - 5.91" / 150 mm 54.0 cal guns - 110.78lbs / 50.25kg shells, 150 per gun
Breech loading guns in turret on barbette mounts, 1937 Model
6 x 3-gun mounts on sides, forward deck aft

54 calibers? 55 was typical secondary mounts on Capitals, though if you're going for broke, look up the triple mounts on the K-Class, which were 60-65 calibers in length. I think you mistook the number though, as I can't see the other four triple mounts on the image.


14 - 5.12" / 130 mm 60.0 cal guns - 73.41lbs / 33.30kg shells, 150 per gun
Dual purpose guns in turret on barbette mounts, 1937 Model
7 x Twin mounts on side ends, majority forward
7 raised mounts

130mm? Not quite - The German DP gun design late-war was 12.8cm/128mm bore, and in tests was found to be quite an effective weapon - so much so many refits were considered to replace weapons with the 128mm gun, including Gneisenau.


12 - 1.57" / 40.0 mm 70.0 cal guns - 2.18lbs / 0.99kg shells, 150 per gun
Anti-air guns in deck mounts, 1937 Model
6 x Twin mounts on sides, evenly spread
6 raised mounts

40mm was only tested on the Prinz Eugen, in single mounts. From this, they developed an improved version of the 37mm gun which had good performance and a better feed system.


56 - 0.79" / 20.0 mm 45.0 cal guns - 0.24lbs / 0.11kg shells, 150 per gun
Machine guns in deck mounts, 1937 Model
14 x Quad mounts on centreline, evenly spread
14 raised mounts

IIRC, the standard 20mm gun used in the German Kriegsmarine was longer barrelled in truth - around 60 calibers in length.

Not being on the attack, just looking at the general armament and making my observations in all regards.

For comparison, what WW Germany is building instead of the historical H class ships (of any design) are these: http://wesworld.jk-clan.de/thread.php?si…75723#post75723

Interesting choice of a 45cm main gun. I see you've got the K-Class 15/60's on there, and the ubiquitous 10.5cm guns. I question the three-triple layout, considering it didn't really take firm hold in Germany, who only used it for their 28cm gun turrets - All the heavier turrets designed were twin mounts, and most of the design studies for Plan Z tended to lean around twin mounts - though Triple and Quads were explored in conservational studies where firepower was wanted but space was a premium.

Here in WW, the German trend has been towards triples ever since the Leipzig class CLs brought it in in 1928. Since then, all the heavy turrets (15cm, 21cm, 28cm, 38cm, and 45cm) have been triples, as were the planned but never built 35cm turrets (that have since re-surfaced on the BCs for Argentina and Brazil that are being built in German yards).
