Looking for some Help - what should Orange lay down in 1920?

[Logi]

Armoring the bow would preserve the speed of the vessel by keeping smaller caliber out. Aft of the citadel it only adds buoyancy protection, while being wasted weight against capital ship shells.

As, I see. I didn't know as there was no note. Makes sense.

Except that on ships which had unequal bow and stern armor, the bow armor was thinner (at least on Bismarck, I don't know if there were other ships).


Hard to believe but I think I actually managed to design a destroyer. However, I bet there is room for improvement and the range is a bit short. What do you think?

Btw, how much seaworthiness or freeboard does a DD need nowadays?

[Logi]

Why such an odd number? At 1600 light tons, it's just outside of 1500t DD tech.

[Sachmle]

That's a little on the low side, even for us "Who needs seakeeping on a DD"ers. I'd try trimming it forward to see if it helps with the seakeeping as well as the stability.

[Nobody]

Why such an odd number? At 1600 light tons, it's just outside of 1500t DD tech.

And why should I care about that? I'm just surprised I ended up with something more or less decent and besides, Orange has the 2000 t DD tech.

It's a DD, cheaper is better sometimes. I'd personally drop 1 5" and 1 3" and see if I can shave off the extra 100t.
I'd probably throw some torpedoes on it too.
Side note, USS Fletcher was nearly identical to this, but it was also 2.4m wider and 0.20m shallower.

[Nobody]

Yes, I'm sorry. That was to quick.
I should have said that the intension was to make a 1500 t+ DD in the first place. And that any tweaking should go into improving it not making it smaller.

Anyway, I always end up making it bigger with hardly any improvement at all. So while your advices are interesting, they are of not that much use unless you can show me them.

Btw, is there a limit for the trim?
I don't like having only a single medium- heavy AA gun, although I wouldn't know how to actually fit two on the ship.
I don't think I can make it wider without loosing speed. And I don't want to reduce the block coefficient below 0.4 something either.



So here are my three best approaches so far, escalating in size while not really getting anywhere:

1 -  NEDS - 7 guns on the centerline. Put the 3"s on the side. Orange should also have access to larger torpedoes.
2 - why I personally ignore what SS2 thinks about seakeeping, the midbreak should be ~2.5m, 1.5m deck height is only adequate for gnomes (as dwarves wielding axes need a bit more head space). Still, it is always a better idea to check OTL ships of similar size, and reference it. Also, try to keep trim below 0.60.
3 - your ship is kinda too deep, B:D ratio should be higher than 2.5:1.
4 - misc weight is too much
5 - 3mm armor on the mounts will be bent by the wind.

5 - 3mm armor on the mounts will be bent by the wind.

The US 5"/38 Mark 30 used on almost everything US made after 1940 had 0.125"/3mm shields.

1 -  NEDS - 7 guns on the centerline. Put the 3"s on the side.

Well, yea but I want to be able to use both in the broadside...

Orange should also have access to larger torpedoes.

No. Two ton 21" is the maximum. Also, I don't really need them do I? I mean, most torpedos ever since have been 21".

2 - why I personally ignore what SS2 thinks about seakeeping, the midbreak should be ~2.5m, 1.5m deck height is only adequate for gnomes (as dwarves wielding axes need a bit more head space). Still, it is always a better idea to check OTL ships of similar size, and reference it.

Well than there have to stairs of some sort. And I can neither increase the height before nor decrease it aft of the break without disturbing the the whole design.
Unfortunately I have no reference to OTL free board heights whatsoever.

Also, try to keep trim below 0.60.

You mean 60 right? That's really low.

3 - your ship is kinda too deep, B:D ratio should be higher than 2.5:1.

That might be true and I would love to see better solutions, but can't do much about that.

4 - misc weight is too much

I don't think so. Radio, Sonar, Fire control and Night Fighting equipment alone weight 100 tons. Plus Torpedos or mines and maybe a "radar". I think 100+ tons aren't really enough.

5 - 3mm armor on the mounts will be bent by the wind.

Well, I admit it's a cheat. Because 3 mm "other gunhouse" armor reduce overall weight compared to 0 mm. Anyway it's an average value and it's supposed to represent small shield walls & roof with a lot of air.

[TexanCowboy]

As I've argued before, destroyers of this era should not have radar. It's hindsightis maximus, useless on a destroyer because of the relative heights of destroyers and battleships, and not at all needed. Also, I think you could use the free radio; it's not like that destroyer is a lone wolf....saves you 25 tons there.

On 1- P3D is right. Not only is it gonna cause NEDS, but the 3'' guns are next to useless on the broadside. The odds are that you'll be engaging at 5'' ranges, and if it closes much beyond that, you use machine guns and torpedoes. The 3'' guns would probably be in use as AA, where the sides will give them a better FOF.

On 2- 50 is average. 60 is intermediante. 70 is pushing it. 98 is  :o. There's no reason that a 98 should be in use....and it's causing you to want to capsize, which is generally right; seakeeping is relative, but stability is usually fairly good on SS.

[P3D]

2 - why I personally ignore what SS2 thinks about seakeeping, the midbreak should be ~2.5m, 1.5m deck height is only adequate for gnomes (as dwarves wielding axes need a bit more head space). Still, it is always a better idea to check OTL ships of similar size, and reference it.

Well than there have to stairs of some sort. And I can neither increase the height before nor decrease it aft of the break without disturbing the the whole design.
Unfortunately I have no reference to OTL free board heights whatsoever.

Try drawings/plans on the wunderwaffe.ru site (should be listed in the links about ships thread), linedrawings on german-navy.de, plans at dreadnoughtproject, or the French ministry archives.

In a destroyer (under ~3000t), the weather deck is the only deck that runs all the length of the ship. The longitudinal framing beams runs right below it. Introducing a 'step' in this load bearing deck (and the frames) would ruin the structural strength, resulting in catastrophic failure very fast. Even the discontinuity of the midship break has such weakness - so the preference for flushdecked ships in several navies.

4 - misc weight is too much

I don't think so. Radio, Sonar, Fire control and Night Fighting equipment alone weight 100 tons. Plus Torpedos or mines and maybe a "radar". I think 100+ tons aren't really enough.[/quote]

Night fighting equipment should not really need any misc weight, sonars/hydrophones neither. My main issue with the hypothetical contemporary radar on everything larger than a patrol boat is the cost - they need highly educated people  to maintain, and just there's not that many available in 1920 that cannot find a much better-paying civilian job. Enough for capital ships, not for destroyers.

  The Destroyer is taking shape - a thought on the Fast AC idea:

- you can adapt calibres for 9.2" and 5"

The Seaboat is only low because she does 33 knots !! - Avge freeboard is a healthy 21'

Your fast ships do 29kts. So minimum speed for a small cruiser should be 31kts. And range is excessive, which cost you a lot. Cut it to half. Go for ~1.00 seakeeping, the ship can slow down in heavy weather.

End and upper belt unnecessary, main belt a bit too high. Armored deck could be shaved down a bit.
