SDN World 3 Ship Design Thread

[Agent Sorchus]

Your destroyer's range is horribly, horribly terrible- it would need to refuel constantly on the way from your east coast to west. And that first battlecruiser is waaay underarmored. Even the notoriously-unarmored Lexington design was to have 7" belt. British BCs typically had 9" and Germans even more.

Sticking with coal makes sense if your oil access is minor, but it does cost you in range per ton of fuel (also, coal grades can ruin performance; lower grade coal doesn't burn as well and you lose power; witness one reason for the fate of Cristobal Colon at Santiago de Cuba).

You are right about the battlecruiser' armor, but this specific ship is much lighter than the Lexingtons were. To fix this I dropped the range by a thousand nm and increased the belt to 6.5in main, leaving it still short of armor but not as critically.

The short range destroyer will remain as a Red sea only vessel and I created an heavier ship to supplement it.

As for oil versus coal I think I am going to have to change the Shakir class to coal. Hmm, maybe only the two that are under construction now.

Your large cruiser should have far better range. Otherwise it cannot do what you want it to do - which is to cruise.

Seriously, it has only 30% more range than the coastal defence battleships I am selling for export.

[Fingolfin_Noldor]

Seems that Spring Sharp 3b3 takes into serious consideration the bulkhead weight etc. and that tends to result in cramped machinery spaces...

[Lascaris]

Seems that Spring Sharp 3b3 takes into serious consideration the bulkhead weight etc. and that tends to result in cramped machinery spaces...

I have to admit I'm not up to date with 3b3 which I downloaded just a few hours ago. Thusly. From what I see there are pretty major differences in the fact that now additional bulkheads and strengthened bulkheads DO affect composite strength and furthermore that beam between bulkheads severely affects the length of armor needed as well as again composite strength.

But I'm at something of a loss on how these should realistically apply on designs. From a very quick reading it would seem to me battleships should be using the additional bulkheads and cruisers the strengthened bulkheads option, while from playing with the same designs on 3b3 and 3b2 it seems the beam between bulkheads assumed in the older release equals beam-20 feet.

So help...?

[Fingolfin_Noldor]

My understanding is that bulkheads help against torpedoes and shells that hit underwater if I recall vaguely, but it seems that these do factor in immensely so much so that my ship machinery spaces went from excellent to cramped as hell. And yes, the composite strength is immensely affected.

[Ma Deuce]

Sorchus, I think you need to totally reconsider your "destroyer" designs (which I would consider to be more of seagoing gunboats). For once thing, they're way too slow for destroyer duties (all real-life destroyers of this era were around 50% faster), and second you're wasting needless tonnage on armor. Aside from maybe some splinter protection over the magazines, armoring destroyers is essentially pointless given their size and role. You should also consider ditching those 6.5 inch guns in exchange for a larger number of smaller guns. Their weight and slow rate of fire is going to make them nearly useless against fast opponents unless they're in powered mounts, which they are not. Also remember that for light combatants that Springsharp allows you to take your composite strength all the way down to 0.5.

In other news, here is the rough draft of my fleet OOB. I haven't finished springsharping the smaller ships, so it could still change. In-service or building Capital ships are almost certainly in final config, though ones yet to be laid down could still change.

[Agent Sorchus]

Your large cruiser should have far better range. Otherwise it cannot do what you want it to do - which is to cruise.

Seriously, it has only 30% more range than the coastal defence battleships I am selling for export.

Minimal change to an oil burning rig allowed me to up the cruising range to +5500nm which should be enough to travel from Cameroon to Somalia with out refueling.

Sorchus, I think you need to totally reconsider your "destroyer" designs (which I would consider to be more of seagoing gunboats). For once thing, they're way too slow for destroyer duties (all real-life destroyers of this era were around 50% faster), and second you're wasting needless tonnage on armor. Aside from maybe some splinter protection over the magazines, armoring destroyers is essentially pointless given their size and role. You should also consider ditching those 6.5 inch guns in exchange for a larger number of smaller guns. Their weight and slow rate of fire is going to make them nearly useless against fast opponents unless they're in powered mounts, which they are not. Also remember that for light combatants that Springsharp allows you to take your composite strength all the way down to 0.5.

I think I shall leave the Hooda alone as more of a destroyer escort. The other design took a major redesign with your advice in mind. As a result it is a whole 2 tons lighter, a whole lot faster and carries an additional 4in gun.

Purely for the lulz....

My 300 m Deathcube trumps your LOLnaught.

Lascaris, all your designs have insufficient armor. Your armor belt is only 12-14 feet, at the very minimum it should be 15-18. Your gunhouse side armor is only 5-8 inches, it should be at least 12. Furthermore, your deck is not armored fully, which means that shells should have a nice time slipping under the main belt and detonating inside. Probably be better if you have at least 2 inch armor there.

[Norade]

How large should a main armor belt be? Also how much does the height of the free board effect that? Right now I have my main belts on my newly redone 1904 Dreadnought at 11" thick and 6m wide, that goes 3m above and 3m below the waterline, then upper belt covers the rest of the free board with 2.5" of armor. Though now that I think of this some minor tweaks to my designs are going to be needed to make armor coverage work.

[Thanas]

Well, Skimmer told me that 15 feet was the bare minimum and that I should think about having at least 18-20feet as well as a 25-30 feet torpedo bulkhead to protect the ships properly. Or at least that is what I remember and have used in all my designs ever since.

[Norade]

Then my first Dreadnoughts are good, and I'll recheck the rest of my fleet in short order.

9-12 18" guns with 16-18" armor belt under 50ktonnes? I'm already struggling to have 9 16"/50 guns with a 15" 560ft long, 18 ft high armor belt, and a 8" deck armor, along with a 21" face, 16" side and barbette for turret armor. Thanas, are you kidding or what?

[Thanas]

I'll post the ship as soon as my budget is finalized. However, I can say right now that the design is feasible and has been shown to several players already - however as you are not an export partner, you did not get to see it until my orbat is finished.

Of course...if you want to buy a ship or two....

To be honest though, I have been fudging with the ship announcements IC due to issues of state secrecy. *And of course there is the small matter of some players not having shown their ship designs at all*

Eh? How is that possible? The Yamato is pretty much the baseline platform for such a vessel. How much weight savings can you possibly get of the order of 15000 tonnes?

[Thanas]

Like I said, if other people would start posting their designs, I will post mine. At the latest I will do it when I post my budget (which is currently undergoing revision due to further arms orders).

I think given my past designs posted in here, you should believe me when I say something is or is not possible. Also, the Yamato had a much higher top speed and higher range, as well as much, much heavier gun armor.

Also, suffice to say that Steve has seen the Springsharp reports of all my designs.

[Norseman]

I have posted all of my designs and linked to them in the OoB thread if you're interested.

[Steve]

I've been informing Fin via IM that I'd okayed your designs.

[Fingolfin_Noldor]

Quick question, what's the maximum armor thickness possible for the face of the turrets in this era?
