SDN World 3 Ship Design Thread

[Fingolfin_Noldor]

It took quite a bit of effort, shedding here and there, while keeping with an average belt height of 18 ft, to arrive at a ship that burns at 28kt, while having a long cruise range at 10,000nm and at 14kts.

So...

Justinian, Byzantine Empire Battleship laid down 1926
Main Torpedoes
1 - 21.0" / 533 mm, 20.00 ft / 6.10 m torpedo - 1.327 t total
submerged side tube

You only have a single torpedo on the whole ship? No reloads?

Anyway as a comparative design the main battery and weight is basically the same as my Majestuoso class that in under construction right now (55,027 versus 55,030) but you get the extra belt and deck (as well as 2kts on the cruise speed) while mine has 2kts more top end.

Well, I have my doubts that torpedoes are useful in a fight, but I might be wrong.

I decided not to compromise too much on armor protection, and I wanted a reasonable cruise speed. Don't want my ships to spend an eternity crossing the Indian Ocean. My belt is reasonably high, and angled, with a good distance between the bulkheads to soak in the torpedoes.

[Ryan Thunder]

Wait--you actually did that on purpose?

Wait--you actually did that on purpose?

Just toying around with the torpedo resistance estimate, though I knew the thing was bloody inaccurate...

[Raesene]

Lascaris, you have your 20 secondary guns in 10 single mounts
You main belt is also angled into the ship, which is (from my understanding of "positive = in") the wrong direction.

[Ma Deuce]

You main belt is also angled into the ship, which is (from my understanding of "positive = in") the wrong direction.

Your understanding would appear to be incorrect: The positive angle = narrower toward bottom is almost universially accepted in my experience: BigGun uses that standard, as does the obliquity calculator for Nathan Okun's facehard programs, as described below in the program's definitions.

INCLINATION ANGLE OF PLATE IS AT RIGHT ANGLES TO DECK PLANE, IS ZERO FOR A PLATE STANDING VERTICALLY, AND IS POSITIVE WHEN PLATE TOP OVERHANGS BOTTOM SO THAT PLATE FACES DOWNWARD (Id)

So yeah, although admittedly I have not found out conclusively which standard Springsharp uses, in light of the above I'd be most surprised indeed if it went against the grain in using the opposite that almost everyone else does.

[CmdrWilkens]

Lascaris, you have your 20 secondary guns in 10 single mounts

I think we've all been using positive angle numbers.

Back to the ship itself

- Armoured deck - multiple decks:
For and Aft decks: 8,00" / 203 mm
Forecastle: 1,00" / 25 mm Quarter deck: 1,00" / 25 mm

- Conning towers: Forward 5,00" / 127 mm, Aft 2,00" / 51 mm

Both of those choices are probably asking for trouble. By going with "multiple decks" your actual resistance to plunging shellfire is reduced as separate decks offer less resistance than a single heavily armored deck. Also you conning tower is just begging to be blown away as even secondaries would be sufficient to penetrate and set it afire causing a severe reduction in your ability to handle the ship. Virtually everyone designing late 20s BB and BC ships right now is going with 14" + of armor (at least on the "Forward" portion) on the conning tower.

I stand corrected, then.

[Lascaris]

Lascaris, you have your 20 secondary guns in 10 single mounts
You main belt is also angled into the ship, which is (from my understanding of "positive = in") the wrong direction.

I think we've all been using positive angle numbers.

Back to the ship itself

- Armoured deck - multiple decks:
For and Aft decks: 8,00" / 203 mm
Forecastle: 1,00" / 25 mm Quarter deck: 1,00" / 25 mm

- Conning towers: Forward 5,00" / 127 mm, Aft 2,00" / 51 mm

Both of those choices are probably asking for trouble. By going with "multiple decks" your actual resistance to plunging shellfire is reduced as separate decks offer less resistance than a single heavily armored deck. Also you conning tower is just begging to be blown away as even secondaries would be sufficient to penetrate and set it afire causing a severe reduction in your ability to handle the ship. Virtually everyone designing late 20s BB and BC ships right now is going with 14" + of armor (at least on the "Forward" portion) on the conning tower.

For the first springsharp fails to differentiate at the slightest. So I just did not bother to change the setting in the program to single deck. It's not a choice in other words just not bothering with a not yet working feature. For the second yes and no. Most navies went for a heavily armored conning tower. On the other hand one can point to British practice as shown in King George V, Vanguard and the design for the Lions where the forward conning tower had armor varying from 3 (Vaguard) to 4.5 inches.

[Lascaris]

Lascaris, you have your 20 secondary guns in 10 single mounts
You main belt is also angled into the ship, which is (from my understanding of "positive = in") the wrong direction.

When cleaning up the ship I will make it up twin mounts and a single deck for the armor no fear. In the meantime as they were not quite affecting composite strength forgot the first and did not bother with the second. But thanks since I;d have forgotten it at all.

[Beowulf]

This existed with bigger guns, therefore mine works. And its what I wanted the Valiente to be in the beginning before I got any funny ideas from Raesene, anyway.

Valiente, Gran Colombia monitor laid down 1920
DESIGN FAILURE: Overall load weight too much for hull

Try increasing the displacement to 8000 tons standard. You can probably skip the aft conning tower. Also try making it a bit skinnier. You also don't need nearly as much freeboard, especially given that it's primarily to operate in the Caribbean.

I edited it because I noticed that the armour on the secondary guns was 630 mm thick.

Mind having another look at it for me?

I'm sure it'll be a great design for land bombardment.

[Thanas]

Lascaris, I'd advise you to have at least 12" in the turret side armor, but of course it is your choice.

[Norseman]

Lascaris, I'd advise you to have at least 12" in the turret side armor, but of course it is your choice.

I think Other Gunhouse is an average of sides and top armour, with the top presumably being somewhat thinner than the sides. At least that's how I see things with my designs, of which only the latest have 12" in turret armour.

[Raesene]

This existed with bigger guns and was never sunk in a storm, therefore mine works. And its what I wanted the Valiente to be in the beginning before I got any funny ideas from Raesene, anyway.

Did you check what this ship type was used for ? Naval gunfire support during invasions, it would have been battleship or even cruiser fodder just like your other monitors. 4'' armour will not protect you against heavy guns, and with just two heavy guns of your own your chance to hit a maneuvering target are close to zero.

It's 40 000 tons so you can license build it using your own docks and for a little bit of extra money we can have them built using Brazilian docks too.

Granted, it has 2 guns less, but in return it has:

- 2 inch more deck armor (7 inches) and a full armored deck including fore and quarter deck to prevent shells plunging through to the citadel. This gives it way more survivability than your class, which is susceptible to enemy gunfire a full 5000 yards earlier. In short, this protection is the same as on the mexican ships, yours is way inferior.
- better belt armor. You have 13.5", this has 16" - and a full two feet higher belt as well
- Also, you forgot the engines in your ships. "No fuel, internal combustion engines..." Eh?
- It is a better seaboat and a better gunnery platform
- better turret armor as well.
- you have no superfiring turrets, meaning that your fire forward is decreased by half. My ship does have superfiring turrets

Lascaris, I'd advise you to have at least 12" in the turret side armor, but of course it is your choice.

We've been at it before but which real life ship have 12in side armor for the turrets? For the Montana's for example it was 10in sides, 12in back and 9.15in top. Which works out to an average of less than 10in. For Iowa it was even less with sides 9.5in, back 12in and top 7.25.

My advice? I would recommend that you use a Brazilian export design such as this one:
.

I would caution Ryan against that design simply because it has no superfiring armament.

I would instead advise to license one of the prized German 40kt export ships, for example the latest iteration of my Österreich class:

Uhm Springsharp 2.1 doesn't really make superfiring armament an option, which is why it's not explicitly mentioned. Since I can't get Springsharp 3 to work on my computer I'm sticking to 2.1. Thus my designs do have superfiring turrets, it's just not mentioned in the 2.1 writeup.

That said this was just a quick modernisation of one of my earlier designs... I forgot that bloody springsharp suddenly removes all your engine checkboxes when you change anything Let me re-jiggle my designs.
