The thought for this challenge came from discussing first Dreadnoughts in JSB's new AU.

This is a difficult one to stick parameters on. Most of the early Dreadnoughts were 18,000 to 23,000 tons with up to 12" armour belts. 18 knots to 23 knots. Gun sizes ranged around the 11"-12". Could you have an early fast battleship (25 knots), but less speed than the early 26-27 knot battlecruisers? Should BC's be included to widen the scope of the Challenge?

There are a lot of good AU's in SB that might want to do a revision of their first Dreadnought class. Go to it!

Comments welcome!



For inspiration, the ship that started it all......

Hmm... Whats the year range for this challenge? For example, Denton's first dreadnoughts (which i need to update, however slightly) were laid down in 1911, with 27,000 tons and 14" guns. However, if the challenge dictates an earlier year range (and lower tonnage, smaller guns), then I suppose I could whip up a concept.

The heading does say 1905-10, up to 25,000 tons, 11-12" (nobody used bigger on their first dreadnought).

Alright, then, just checking.
Well, technically, the New York class BB (of which Denton's first dreadnoughts are based) have 14" guns and the New York and Texas were considered dreads... *fades out* :P
But, fair enough, I have an idea for a dreadnought of that time period.

For my entry I have gone with a fast battleship concept. 23,500 tons normal displacement, 634x86 feet, 10x12" 16x4", 45,000shp for 25 knots, 11" belt, 2" deck, 10" turret and conning tower armour.

My mate Jackie Fisher wanted less armour and more speed, so I had to fire him even earlier than in my other thread.

It is possible to fire all turrets to each broadside, but after the initial trials firing this would only be done in time of war. Trials found that the blast from the guns lifted the wooden deck covering and blew it over the side.

I think you could interpret it 2 ways,

1) A first dreadnought in the opening wave of 1906-1909, this would likely be small with 12" guns in mostly suboptimal layouts and 19-21 Kn speed, examples would be,
- HMS Dreadnought herself
- South Carolina
- Nassau class
- etc

2) the first dreadnought for some obscure (AU) Nation, this could easily be later (and a much better ships)
some examples of a first dreadnought, (getting more powerful as you go down ish)
- España class
- Dante Alighieri
- Tegetthoff-class
- Minas Geraes
- Courbet class
- Gangut-class
- ARA Rivadavia
- Almirante Latorre
- Reşadiye-class
- Fusō-class (technically first as BC/Semi don't count :lol: )

So is ether OK or should be have more specific rules ? (and do BC count , ie was Kongo the first for IJN she would have beaten many of the dreadnoughts on this list)

IMO your fast BB is just a little to big to be realistic not just money but dock availability will be hard to deal with. (looks like a 1910-14 export fast battleships so could be first but don't think for RN or 1906 personally)

Fuso? Try the Aki and its sister with 12x12" in lozenge arrangement.

OK I accept that the Kawachi class are really dreadnoughts even if badly designed with 2 types of 12" so cant range effectively (isn't that the whole point of having just 12" guns !), but don't think AKi counts as a dreadnought (12"/10"), so Fusō class are first with uniform battery (if you exclude BCs of the Kongo class, it was a bit of a stretch to show how far you could go ;) Almirante Latorre and Reşadiye-class will have to do instead)

Hell again!

I really wanted to collect a few more fictional Ottoman ships and post them as a complete AU, but what the hell... how about that one?

[ img ]

German built (obviously) as a reduced Kaiser with suitably shallow draught for Turkish waters and - most importantly - an early enough design to be delivered before the first world war starts (maybe even in time for the second Balkan War, which might change history quite a bit).

Overview: 22.000 tons normal, 24.000 tons full load, 22 knots, 8 - 305/50 guns (arranged as on SMS von der Tann), 12 - 150/50 guns, 18 - 88/45 guns, 4 - 450 torpedo tubes, Armour 300mm vertical/40+40mm horizontal/40mm torpedo bulkhead.

Greetings
GD
