With some very dodgy advice *looks at Tanthalas and Sachmle =)*, I've decided to lay down run of 1 (at this stage anyway) BC, the HMS Hood, Pride of the UNK Fleet.
Thoughts?

Any Ship called Hood - gets my vote ;D
But - dare I say it - would prefer a bit more armour round the Magazines - esp. vs. 14" gunned opposition upwards
If size + cost are at a max. - maybe scope to shave off a bit freeboard/seaboat qlty ( I think is least critical parameter for Big Ship) or range ?
Whatever you decide to do - can we have a picture - PLEASE ;D :P
Yes, a picture please for the UNK Hood ...
Jef ;)
Ok ok, I'm sensing a theme here...Lemy get up to speed on my reports, and I'll get a picky done.
The Royal Navy currently has no Battlecruisers, and this is seen as a major deficiency. Its current plans are to lay down the Hood, along with several smaller, lighter BC's. The RN is planning to lay down no less than 4 (and up to 8 ) of these between 1917 and 1919.

interesting - what are the smaller BCs for - type of role and likely opposition
i'm thinking the opposition is getting bigger and just as fast - Mondedor etc
the Lion is reasonably priced - but it lacks ROAR ;) - in fact - more like a domestic pussy :( . ....
an alternative would be 3 Hoods with 14" armour mmmm yummy .....
Ahoj!
Mentat rises a good point - could a 4x2x15" HMS Hood carrry a 13" (or better) belt?
Then I'd call it a day and build four.

Quotecould a 4x2x15" HMS Hood carrry a 13" (or better) belt?
Considering that I have a 27 knot design that is like HMS Hood, but has thicker armor and is some 6000 tons lighter than Hooper's Hood, I would say that that is certainly possible.
Revised it a little, just some tweaks (Thanks Tan!). I can get better armor, but she's a battlecruiser, not a battleship. I Want to get it to 30 knots, but its just not possible with 16" guns. Going to try a 15" design...
If you want 30 knots, you really should go for 15"... or a bigger boat. :)

Cant do it with 15" guns either its the weight necessary on the ship, the SHP restrictions bite you off at about 29.5 even for asfolath without making massive cuts to say main gun numbers
i'm guessing 41k tons (full Hood size ;D) 8 x 15" and 30 knots and still decent armour (armour could be +1" for Mags) should be possible .... hope so ... this is a critical project ;)

well it kind of depends on who is building said BB... the reality like it or not is you cant build the OTL Hood on 35K SHP. so your looking at like 1920 before she can be layed down.
The final version Hooper posted is about the closest you can get (admitedly the 16" is a deviation but its still close)

I tried, I really did...but like Tan said, you just can't get 30knots out of 35k SHP per shaft. Need more power captain!!! It should be possible 1920...expect an engine upgrade =) To get those 30 knots (in 1917 with SS2), it has to be smaller, and throw any idea of "balanced design" out the window.

Never mind - and well done for trying :) - SS really penalises on Speed, 29.5 knots was Hood's final speed as an Old Lady - and I think the protection is more important anyway
Nice Destroyer btw - very handy - my only query is re Freeboard and Seaboat Qlty - would a bit higher freeboard be useful for North Atlantic - they seem to have the range to be Ocean going
also Q'deck is 3' lower than main deck - mmm - seems bit odd
Yeah, think of it as a flushed deck DD with a flared bow to try and deal with that North Atlantic Weather.
3' step on the quarterdeck. I can see reasons for that. For one, it creates room to work under the barrel of the aft gun.
Getting back to Hood
I have recent design I dug up for 'Fully Armoured BC" (like an Early Vanguard)or perhaps what Hood should have been ) - I guess a Fast BB in reality - 40 k tons 15" Belt but just 28 knots - interesting to compare
And I can't help wondering - with current limit of 140k shp - since 30 knots requires too much compromise on protection - the fully armoured ship is the better buy
- what does everyone think ;D

Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform
Good seaboat, rides out heavy weather easily
I really like this one - good competitor to Mondedor ...
Deck armour and Freeboard/Seaboat Qlty are prob. excessive - could trade off for a bit more speed - but I guess 29 knots is still barrier with less than 140k shp
Ahoj!
The 28kn version looks better to me than the faster versions. But the AD seems excessive or too much hindsightful. Also, I consider MB over 14" to be a waste.
I personally have a policy of cutting back "fire platform slightly" down to 70%, with the balance going into "stability".

She's a good companion to Montmedie and Mont Bruyere. That half kts top speed won't make a difference.
But, change the belt to something thinner, and use the weight to increase the hight of the main belt and to make the TB a tad heavier. 2" ain't to little.
The light secundaries could be seen as a flaw in an era of increasing DD size.
On cruise speed and range. France is building the newer ships to 16 kts cruise speed, and the ranges vary between 6000 and 9000 nm.
Yes - agree with those points
maybe - Belt 15 (Mags) 14 (Mach'y) Deck 5 (Mags) 4 Mach'y
increase TB and Sec's - 20 x 4.7" or 16 x 5.1" - should do it
I'd forgotten I had included Upper and End Belts - so it is very well protected, but maybe otherwise Stab'y would be bit higher
Range - this is general design study - I think is up to Individual needs - just need to tweak other bits if anybody needs more

AD?? Air Defense? Armored Deck?
I like your design Mentat, but I'd argue that the Hood isn't meant to make sense. She's meant to be the pride of the fleet, fast, overpriced...with some glaring flaws.
I think she made sense in real world at the time - as well as being so damned good looking (from most angles - perhaps not side profile)
- question is - what makes sense in nverse right now 1918 - nverse seems to have more armour + less speed - prob. courtesy of SS program
I will try to tweak the design a bit - get bit more speed - I like speed too ;D
Ahoj!
Sorry Hooper - yes, indeed, AD stands for Armoured Deck. MB = Main Belt, MG - Main Guns ...

so I was playing aorund with HMS Hood today, and I actualy got her to work mostly. so I thought this would be the best place to post it, I definetly wouldnt object to opinions (as always) oh and im contemplating a way to trim a little more weight (which would go right into the Misc. weight). what is everyones opinion of a KGV style lightly armored Super Structure?

Nice, but you forgot the 7" upper belt and I think she was laid down with 5" guns, not 4.7".

Actually, her secondary battery was 5.5".
it was more an atempt to make hood work in the nverse, im not the person playing the UNK at this point so its more like Mentats ship than an actual nverse ship.
