Naval ship design involves complex trade-offs between firepower, protection, and speed, as demonstrated by the H39 German battleship design in Ultimate Admiral: Dreadnoughts. The player must balance 18-inch main guns, armor thickness (reducing from 3.9 to 1.5 inches for belt armor), and displacement (80,000 tons) while managing weight constraints. Key decisions include selecting appropriate gun calibers (460mm main guns, 155mm secondary), tower configurations, and armor layering (18/9/4.5mm layers). The design prioritizes maximum firepower and protection over speed, accepting a slower 28-knot speed to achieve superior armor and gunnery capabilities.

H39 o Clock - Episode 31 - Legendary Good Guy Germany Great Game (5G) Campaign
Added:Hello, brother Ben here. Welcome back to the German campaign where America is proving a little bit more tricky than I was expecting.
They've absolutely hammered us with their superior numbers.
Especially in the cruiser department, they've got so many nasty cruisers.
Anyway, most of our fleet is currently being repaired, which isn't great.
But, um we do have one of the surviving Odins in Malta that has finished her repairs.
So, what I'm going to do is we're going to get a refit of these ships on the go, an emergency war refit.
Essentially.
To try and improve their performance.
Although, looking at it, there's not a there's not a ton ton to do, actually.
Um improved prop shaft Krupp three to Krupp five is a big help.
As you can see, they're five.
Uh we can get them diesel electric auxiliary engines.
Mainly cuz it has uh better better flood resistance.
Two-pounder one, we can go up to two-pounder three, which is A safer and B less pathetic.
And we can get semi-auto loading guns, which is a big help.
And we can upgrade the guns across the ship.
Uh do I have a different model?
No, I basically have these or these but with a different shade on them.
They look ridiculous at 52 calibers.
Um Right, problem with the 5-in guns is the bunny ears getting in the way.
When we swap them to non bunny ear versions.
Oh, something that people were asking me to do was change these to 88s.
It's being a more German caliber, we can do that easily enough. Not that it makes a huge difference to the ship, but we can do that.
Um Okay, we have a little bit of displacement remaining.
Now, what I found was a 10-in gun.
Yeah, there's no way we can armor against that.
The argument we would would be to reduce the amount of 4 and 1/2 belt.
Cuz 3.9 is keeping out like a 7-in gun at some ranges, but I mean, if they're within 12,000 m, that's pretty enough.
Yeah, I think we could go down to go down to 1.5.
I know it seems weird. Oh, you're having trouble losing your ships.
So, reducing the armor, but it is the whole idea is that it is all or nothing. So, I am actually going to embrace that, cuz we've just been taking too much damage from medium sized guns. We're going to take this down to 40 mm.
We do already have maximum bulkheads.
We need more more uh regular armor, I think.
Uh 250 200 Okay, 416 and 130.
Okay. Uh deck armor I'm just going all in on the last 45.
35 25 That's better.
Uh I think this is pretty much the most I can get. No, it's not.
We can go all the way up to 500 mm of uh armor on the turrets >> [snorts] >> 500 on the tower uh 420 bar bit Something like that.
Can I think of those 5-in guns and have them still fit now that I've changed taken off the money is Yes, I could.
Okay, that means extended range on the 5-in guns as well.
Okay, main change of those guns though cuz they're Oh, rate of fire is terrible.
0.90, I'm going to reduce their length.
I think we should be using 45s.
1.2 rounds a minute, that that's spot-on. That also gives me a bit of displacement back.
Uh no chance I can push speed, is there?
Ooh, actually there is.
We get them up to 32 knots if I trim something.
The obvious thing to trim is this, but I don't think I can get enough savings from that.
Uh Wait, fuel.
Don't fuel.
We don't need fuel.
Yeah, that that I think should be better. An emergency upgrade for the five survivors.
Save.
Now, uh several people in the comments have pointed out we should maybe have our own 18-in armed ship that is bigger and more powerful.
Uh I do agree with this.
Uh suspend to sus- delay some of those destroyer refits, would you?
No, that's not going to cut it.
Going to have to suspend something that's repairing for a million years.
Hessen.
390.
Hessen and Lothringen suspend for now.
Uh right.
Yeah, in terms of that medium guns, we're starting to get the Mark V stuff there. We're starting to get Mark Vs over here, too. I should kind of want to get the medium guns done first.
We have the Mark III 18s coming along in 3 months' time, so we do have the option to build a super battleship around the 18-in gun.
Uh but that won't be for a couple of months.
No, that's the last thing we need.
Uh That's a lot of money, but it might be worth it. We are very busy right now.
More cruisers.
Okay.
Yorck up to the plate.
All the surviving battleships need a star, of course.
This should hopefully just be a bit of cruiser deletion.
Yep, Vanguard, Scranton.
>> And half it.
Here we go.
Swapping out the Marblehead.
Who is swapping out for the Oklahoma?
Nobody wants to be the lead ship at the moment, it would seem.
Now they're starting to go the other way.
Just so many of these things the Americans have.
Right.
Okay.
We are getting there.
Um Okay, they're still not able to progress that one. We are not able to progress this one though, which is annoying. I've called for a battle.
Okay, yeah, we need to do that one.
Um Here we're getting on. Okay, we've got three operational Yorks.
Uh two in Santa Cruz.
Uh make a run for Gibraltar, please.
It might help a little bit.
Uh how's the army getting on?
Slow.
Slow is the answer to that.
Okay.
Um We still also have the one Wanderer Town, but she is uh the Hessian, she is still repairing.
But I can unsuspended that.
Get rid of this design.
Okay.
The convoy.
Let's go.
Oh, [ __ ] I did not mean to press that button.
[ __ ] me.
Why did I press that?
Never ever press auto resolve.
I hate auto resolve with a passion.
Tempted to disable the [ __ ] button.
>> [laughter] [snorts] >> Why did I press that?
I've I'm so I'm really tired today.
I'll I'll blame it on that. Really not feeling great. Um thanks to picking up a cold which yeah, when you have a severe ME, that's [snorts] not a fun time.
No no items to refit yet.
Oh, they all need a uh star, of course.
Uh Hessen is at a star.
Uh Yorick's up to three uh cuz I know she's been in and out of battle.
Same for Barton.
And Tippit's is on the second.
Hindenburg still don't have thing.
Prinz Heinrich you can earn a star for auto resolve being stupid.
Okay.
Okay, so their invasion of Gibraltar failed. I just pointed at the screen with my finger like you could see that.
>> [laughter] >> That is how tired I am.
Goodness me.
>> Well, this is an opportunity to take out another American cruiser.
Which they have infinity.
Stupid as an order somewhere.
There you are.
What's their armor like?
It's not that good.
Just not getting a good hit.
Got him.
Okay, small small scale, that's fine.
Doesn't need to be large scale battles all the time.
Uh, you're another star for you.
>> Uh [snorts] yeah, we're going to have another one ready next month for refitting.
Taking the central Balkans.
Something There we go, mark three 18s.
Okay, but our invasion here has failed. So, they have 400,000 victory points.
We have 2 million.
So, it's not the end of the world.
I get those two refitting.
Have one Grosser Kurfürst completed her refit, that is promising. We I can still have nine, 10, 11 capital ships.
>> [snorts] >> Do we have any others? One battleship there, there's a battlecruiser over there.
Yeah, they've got their six battleships over here by Sardinia still.
Hmm, I really want to take that Maldives back. But I know that if I launch a naval invasion, every American ship will descend upon me.
Um Do also have my four battlecruisers in Gibraltar.
All right, let's move uh things to Gibraltar.
That might also generate back the old the battles they're moving, but I'll try and blob up a little bit.
>> [sighs] >> In the meantime unless there's a tasty juicy research about to come up which there isn't, we need to get ships in the water to well, refill our losses effectively.
>> [snorts] >> And I think that means 18-in ships.
ships Now the modern battleship two and the super battleship can both do this role.
Super battleship two is too big, I would argue.
And modern battleship two is big enough.
Uh 27 base accuracy, 24 base accuracy.
We'll go with a a big big superstructure.
And let's look at these 18-in guns.
We have this model which I'm not as big a fan of.
And this one which is perfect but does not fit on that tower.
Ah, yes. I remember the problem with the uh the German ships now. They have a woeful selection of towers.
Just gold awful.
towers Yeah, I think we'll go with the modern two.
And I just use this.
Um >> [laughter] [snorts] >> I'm going to Actually, no. I'm not going to slim it down.
No, we're not going to slim it down.
Going to keep here chunky.
And 10 Yeah, wow, that's Yeah, no.
Yeah, the nice but button battle cruiser over there.
Maybe two needs build a more super hull, but Look Look at the size of that thing.
Look at it. It's huge, right? Absolutely enormous.
And you go, "Oh, I'll go get an 18-in gun for this enormous thing." Oh, at least this one fits.
Okay, there we go.
I need the ship longer though.
Look at Look at the displacement.
And then the secondary tower, you're like, "Oh, well, I'll get this one." 26 base accuracy.
Which is pretty much the best one.
Oh, yeah, look.
What the flip?
Need length.
So, we're talking about a 75,000 ton ship. No, talking about an 80,000 ton ship.
That one doesn't even fit. There we go.
To fit its vast towers.
And even then, it has section sectionality problems.
What the hell? I hate the German towers sometimes.
Let's go with a two.
Two and a four. They look a little bit more reasonable.
All right.
A little bit more reasonable.
Does still fit the guns.
Good.
And if I'm building a 80,000 ton ship, I want a lot of guns.
There we go. Okay, I probably probably could get slightly bigger towers then.
So that one fits.
But this one doesn't.
No, it does.
Okay, so we'll go with a three.
>> [snorts] >> Three and a five?
Does that fit?
Just.
Just.
On an 80 thousand ton hole.
Goodness gracious.
Uh okay.
Well, I've got getting somewhere.
Uh our highest gun mark is a 6-in.
Uh probably the one without the bunny ears, please.
Don't even know if that one's going to be able to fire properly, but we'll go for it anyway, and then pom-poms Well, these are going to be 88s by popular demand.
Um Okay, and a funnel.
I'm going to use that just cuz it's huge.
The thing about this ship is silly.
Uh 20 28 knots are actually slow.
I'd like them to go to get to 30.
Yeah, get down below is the better option still.
Give them these electrics, though.
>> [sighs and gasps] >> The best protection we can provide, apart from a triple bottom hull, is to make too heavy for what it does.
Might need to reduce those in a minute.
Sh pan of three, semi-automatic electro-hydro, what's my flash fire chance?
Zero.
Zero.
Really? Zero.
Go for FU shells then, even though they aren't cheap enough.
Uh Or actually no, I got to go stereo on these. This is more German choice.
Anyway, but these should be fairly long-ranged guns, one would hope.
Uh they've got excellent pen.
But the HE is probably a bit much.
[sighs] Base fuse, perfect.
Okay.
Um I mean, does this massive thing come with armor? It does. Well, that's a plus.
Yes.
Armor, um Yeah, we're going to go 1.5.
Deck armor, uh yeah, five five and a half, fine.
Superstructure.
Actually, the superstructure might want a little bit more armor.
Um Let's say someone was firing a 10-in at me.
Yeah, that's still a bit much, isn't it?
What about someone had like a six or a seven? Yeah, it's too it's too high.
Just reduce that.
Layers, yes.
I'll work out what they actually should be in a moment.
Turret armor, yes.
Obviously, I'm going to have to reduce this.
But it's good to know where where your kind of maximum armor is.
Uh to Okay, so 20-in main belt, I don't think is practical.
Although, that's what I really want.
Let's assume the enemy is using a 16-in gun.
Yeah, I think an 18-in main belt might be a little bit more reasonable.
Uh and turrets can have 20-in.
And the barbette can be 18.
And then the layers then, 18 / 2 is 9. And that's correct. 18 / 3 is So, this needs to be more like six.
And 18 / 4 is 4 and 1/2. So, the layers aren't all a million miles away.
Um this should just be down to like that.
Okay. Now, let's switch to millimeter mode to fine-tune everything.
So, 457 mm guns.
Yeah, yeah, we'll just make them 460 mm.
Uh we'll make these 155s, but we want them long.
And now they don't fit.
Yeah, this one. Maybe maybe I'll swap that one out for the smaller version.
No.
Next one up is the one I just had.
Yeah, swapping it out for the smaller one.
Cuz then it'll actually fit.
And save me some weight, which we was needing to do anyway.
Uh [sighs] should this level weight, but never mind.
Well, let's go 460, 40 40 140 40 40 40 Yeah.
Oh, yeah, that needs to be thicker. Um go 500.
500 150 460 Add 225.
150 100 60 45 35 120 40 and nothing is not really what we want. Let's go for 40.
Let's splinter proofing on them.
These need to be 88s.
Okay.
I think we're about in the right ballpark with these.
Except [snorts] that we are overweight.
And not by much though.
And I thought I can get away with just making it bigger. No.
Now, we need to lose 400 tons somewhere.
400 tons I think I could get out of many bulkheads. I'm not a huge fan of it. But I think it's the best option.
And I could make them slower [sighs] as well.
Yeah, we'll make them slower. It We We should be able to fix this later.
But for now, we'll just make them a little bit slower, 28 knots.
Lots of our fleet still only does 28 knots.
Uh but yeah, these things are enormous and very expensive.
Uh, but they should do the job. Now, the name the name I'm not sure about the name.
Right, in honor of the fallen we'll go call it a Von Richthofen.
Um, that is a that is a big ship.
A really big ship.
Um, how does she compare to Yamato?
Out of curiosity.
So, uh, Yamato.
Uh, Yamato when she was built do do do do do do do do displacement full load 72 73,000 tons depending on how you measure it. So, we're about 10,000 tons heavier than a Yamato.
We have three extra got big guns. We have uh, more secondary guns than they do. They had four triple six point ones. We have uh, 14.
>> [laughter] >> Uh, but they did have also have the six twin uh, five inches.
Um, and then yeah, we've got the 18 quad 88s.
Hm, our turrets aren't quite as heavily armored, but our belt is even more armored than the Yamato's. Yeah, that seems reasonable. What about an H class?
H class.
H class battleship proposals.
Uh do do do H39 Yeah, this is H39 territory, I think.
80,000 tons they used the 40.6 cm guns, apparently.
We are using 46 cm guns. Screw your.6.
Um Yeah. Okay.
Um sure. It's an H39, sort of.
It's big.
That's what it is.
Okay, save design.
I'm not going to be able to build a lot of those.
I'm not even sure I can build one of them right now. Oh, no, I can't. I can build one.
one single ship Uh there.
No, there. It's got more capacity.
>> [sighs] >> Uh that is going to take a long time to build.
So, that is probably not going to be available for this war, unfortunately.
Right. Um let's do this one.
Oh, and while I remember, uh do do do do do do dreadnoughts development Uh comments.
1.4 road map.
Confirmation button if player selects auto resolve.
Are you sure you want to auto resolve?
You sure about that?
Aha.
Right.
Pascagoula destroyer.
Get away from my transports.
Got him.
Suck.
Good.
Right. Now for the cruiser.
This is a AI design, I think.
AP, please.
>> Does that sub torpedo? Yes, she does.
Hard turn.
Yeah, throw some high explosive through her extended armor.
Please.
Come on.
More damage, please.
AP.
Which then misses.
That is hitting, it's just not doing very much.
Fine. Automatic.
Yeah, she did the torpedo washes off.
Got him.
>> Eventually.
>> Uh, good.
Good, good, good. Right, what's going on here?
Oh, Italy's trying to re- reappear. Yes, I suppose we are supporting uh Italian Italian regeneration.
Italian independence.
Anyway, I'm going to go in the turn and see what happened. Um, or not. I didn't even know I was at war with Italy.
Um.
What?
War and then Okay. Okay, right. Okay, so they declared war on Japan for some reason and then immediately peaced out. So, basically, they didn't declare war on us. Okay, fine.
Minnesota [snorts] versus Tirpitz.
Hm.
>> [clears throat] >> That's little battle is going to be the next episode. Thank you very much for watching and I'll see you again soon for some more Ultimate Admiral Dreadnoughts.
Bye for now.
