1920s Costal battleship design challenge.

Having been inspired by some of the design challenges I would like to set one.

The 1920s (WNT etc) are an interesting time, but instead of the big normally looked at powers why not look at the minor powers so my challenge is to build a costal battleships for a minor power anybody who isn't named in WNT+Germany+USSR will do.

The Rules.
- Build a costal battleship, a ships to defended your coast ? (mainly from surface ships or to provide NGFS)

- Must be built by or for a minor power (not named in WNT + Germany + USSR).

- Must be built (laid down) post WNT and pre Wall Street Crash. (doesn't have to be finished till 1930s as you are a cheapskate, but you cant fully rebuild it with 1930's tech)

- It should pretend to be under or close to 10,000t as a WNT power will not like you if you ruin the treaty, they will not build it for you over that or help you with equipment if it is to much of a threat (you should explain anything over 10,000t and you must persuaded the other voters its ok (Deutschland class is ok but limit your cheating to semi believable amounts ;) the more rubbish/less threatening it looks the more they will allow you to cheat).

- should use weapon's that you can buy or build (so keep to mostly real types as you don't have that big a development budget and buy from your nations friends or neutrals).

- The ship will be judged on the threats at the time (not can it survive Fritz X or should you have built type 21 instead)

- For maximum bonus points it should make use of free/cheap stuff from ships scraped by WNT (always thought it was a waste not to use some of the materials or weapons from them)

- Anybody can enter and the winner (after say 1 month) will be chosen by voting (As I fully accept I'm not the expert judge and I want to enter myself :lol:) by all who enter a ship (you cant vote for yourself ;) ).

JSB

PS will add my entry soon when I'm happy with it. and I hope its ok to set challenges :P .

Deutschland class is not an coastal battleship! to big.

look at Sweden and Sverige class, it's an Coastal defense ship. but it's to big to be one, so you can call it more like an mini battleship.

if you want a ship that can out-range most guns in 1920:
[ img ]

it's 9.2in guns has very long range, the only gun with create range is monitor equipped British 18in guns. the 9.2in shell that was suposed to be made by NAMO in Norway for the 9.2in gun's. had creater penetration against ships and bunkers with an almost howitzer flight pattern at the end of it's flight. what more do you need.

Just to get you interested my WIP (will add the back story latter).

You know you could do better ;) .

If it is a coastal battleship, there is a differance between coastel-defense ships and a battleships, its displacement should not be limited to 10,000 tons. For that, you`ll get a decent light cruiser, or a shitty heavy cruiser. If it is for a non WNT navy, nothing about said treaty should apply, and as such, there should be no restrictions upon the designs. Germany only had restrictions from the Versailles, which they were only too happy to break. If you do decide to go for 10,000 tons, you will get a ship that will be good at nothing.

The problem is that minor nations will probably need help (or all of it doing for them) to build a ship. the WNT powers (or Germany as well for different reasons) will not sell you anything over 10,000t thus the limit.( but they may sell you parts if they think or choose publicly to think that what you are building is under 10,000t ).

So although I would not be limited by a treaty I didn't sign very few nations will sell me stuff I need to make a ship over 10,000t so I might as well be limited.

Short info about my ship,
My ship came about when I was spring sharping and found I can get 3 13.5 twins in nelson type arrangement on a pocket BB size ship, my reason for them would be to fight the IJN or at least act as a risk fleet as the IJN cant afford to lose its BBs/BCs before fighting the USN/RN. I will write up properly and post.

Here is my entry. I havent found a nation or a name yet. I could think of Greece or Turkey as likely candidates. The ship is built in the US, and uses three of the five 12inch turrets of the decommisioned Delaware. The ship is laid down in 1925.

Hm... looks very interesting, I might get in on this... I have two versions of an "ideal" CDS, the first is your typical two two-gun turrets, one on each end.

Not as kosher of a design. Here I went all out according to my own design philosophy in regards to ships with the CDS mission. Number of barrels is more important than the caliber, but staying above heavy cruiser artillery is still paramount. I've said this many times, but for a ship who tries to get in between the battleship and cruiser bracket when it comes to what they're fighting, the 240 mm/9,45" is pretty much the best caliber if you don't want expenses to run up too much. She combined six of these guns with a, for a CDS-ish design, a very high speed of 26 knots, which will allow her to run away from most contemprary battleships at the time of building. She also has heavy armour, allowing her to take a relatively heavy punch.
The only downside to me is the short range, but considering these designs are for a small nation, it shouldn't be too much of a problem.

Hum, might post a few comments on what's been posted so far.

Heuhen: You're right, we frankly have no chance against you. :P ;)

Karle94: I personally think 12" is a bit overkill, but I can buy it with you backstory.
I would though suggest that you mount two 12" turrets aft and one fore. While this ship might have battleship guns, any fight against a battleship will result in your ship fleeing at high speed, and then it's good to have the majority of your artillery able to fire. Otherwise it will probably stay at long range against enemy targets(that should idealy be cruisers and below), to maximise her armour, so she'll probably be steaming slightly away from an approaching target, since they'll be able to deal a lot of pain to your uppenworks even if they can't penetrate the belt. It's broadside fire that's really the important thing.

JSB: I'd like to see a Springsharp report, or some other list of data. Everything I mentioned to Karle94 stands though. A CDS will be fleeing from anything with equal artillery(most of the time), and having none of the main guns availible for stern-firing is borderline suicidal. And guns of that caliber is really overkill(since you won't be fighting battleships with a CDS, however romantic the notion is). With a smaller caliber she'd be able to increase speed and/or armour.
Oh, and the gun you use as the secondary gun came into service 1936.

I am working on a design similar to the original one with only two 12 inch turrets, and four 6 inch turrets. It will have lower freeboard and shallower draft to increase stability. Overall length and width will stay the same.
