It will be interesting to see how it turns out. I would note from the SS report that your ship is only 30 feet wide, which might need a bit more to fit 12" turrets on.
Well if I put the bulges in correctly its 80 ft breadth at the waterline and 30ft at the widest deck because of the tumblehome.

Also the reason I left it at 1.08 is that I have no clue how to account strengthening of the hull other than pointless bow armor of 2in as its to be Ice breaker first, dreadnought second, as not every navy has the economics of colonies like Britain :twisted:

I think maybe you should try an overhead view of your ship and see if you can fit the armaments and other fittings on, in the space you have provided. Might be interesting.

Has a nice 'different' look to it that makes it feel like an early dreadnought and interesting. :mrgreen:

My only comment would be to maybe recolour the 12" mounts/guns ? I think the same as the superstructure would look nice and make them look less like they have been cut and pasted on.

It certainly does have a different look. I like the concept, shows a different thinking/concept to the rest of us boring people.

However, you can see from the overhead you have no working area between the main turrets and the ships side. You do need to have access to the front of the ship and the stern. You are also about 10 years or so ahead of your time with the quad 130's. The French went with quads for the Normandie class and those are the first quads I know of. You have done a cut/paste of a 1930's turret which does look a bit odd. If you have a look in the main Archive in Real Life, French and have a look at the French armoured cruisers. You will see in among those some armed with twin 6.4" which would be a great secondary armament for the time. You should also have a few 75mm anti-torpedo boat guns. You have done a good job, just some things are mis-matched for the time period.

Where the 130's are positioned, you are also going to require handling rooms underneath the turrets. About where I would normally expect boiler rooms to be (from your funnel placement).

So there is now have starboard, top, bow, just ahead of front boilers/cross secondaries, and midship/cross coal.

Laid down in 1905 under the paperwork of ice breakers to appease congress, the four Muscatatuck-class ice breakers (Muscatatuck, Dauntless, Aurora, and Glacier) were much more. Labeled an ice breaker, and capable of the part, they were a dreadnought in reality. Armed with six 12"/45 guns she was capable of outgunning most pre-dreadnoughts and armored cruisers, however during construction the eight 240mm/50 secondaries were canceled after the barbettes had already been affixed, to simplify the sixteen 120mm/55 tertiary placements, the deckmounts became four, two twin mounts adjoined atop the 240mm/50 barbettes resulting in a quad mount that behaved similar to a wide arc casemate.

Updated spring sharp to better reflect icebreaking, atleast it seems to have.

Looks really great, Muscatatuck! She's a unique take on the original challenge at it came out very well. That's some serious tumblehome! I like the icebreaker bow and the propeller at the bow as well as the stern.

I've been following this thread since it was created and have really loved the work people have produced. I've been inspired by many of the designs on the forum and I decided that I would finally bite the bullet and contribute.
So, without further adieu: the Maritime Union's first dreadnought, HMMS Argus of 1908.
[ img ]
Displacement - 23,000 tons
Length - 600 ft.
Beam - 88 ft. 7 in.
Draft - 28 ft. 5 in.
Installed Power - 32,000 shp
Propulsion - 2-shaft triple expansion engines
2-shaft turbines
21 or 28 coal-fired boilers
Speed - 21 kts.
Range - 6,500 nmi.
Complement - 50 officers
120 petty officers
1,000 enlisted men
Armament - 12x12 in. guns in 3 quadruple turrets
24x5.4 in. guns
6x1.9 in. guns
Armor - Belt: 12 in.
Turrets: 13 in.
Bridge: 12 in.
A short history of the ships:
When Great Britain launched the Dreadnought in 1906, the War Ministry of the Maritime Union immediately sought to catch up with their British rivals. The people of the MU realized they had been lulled into complacency by the cookie cutter designs of the pre dreadnoughts and wholeheartedly supported the new building program. It took two years before the Argus class was launched, but the citizens, government, and navy alike knew it was worth the wait. She was larger, better armed, and even more revolutionary than her British counterpart. Three ships of the class were launched while another new class of three was on the drawing board. The launch of His Maritime Majesty's Ship Argus ensured the MU's place as the preeminent sea power of the twentieth century as the British Empire declined.

I'd be tempted to plug the center turret and install more boilers, but then again I love speed:)

Overall, very Normandy like, also if you raise the stern turret, could you relocate the stern, maybe even some of the side casemates further inboard to get them out of the spray like the bow casemates, they just seem really wet?
Sounds like it can take hits well, I like it overall.

Thanks Muscatatuck. I think I will relocate some of the casmate guns further inboard. As for the speed aspect, I think I'll switch the propulsion from half and half triple expansion and turbines to all turbines. That should raise the max speed by a few knots. I'm also thinking about making the quarterdeck either flush with the main deck or close to it. That should make her a better seaboat and make firing the aft turret easier in heavy seas.
