UNK Ships 1917 and Beyond

[ctwaterman]

Below is my take on HMS Hood for the UNK this is the version will most likely be laid down in 1917 there is a copy somewhere in the Old posts in this section but I modified it a bit when I was making up the new SS for my Files.

By all means critisize away she did end up larger then the 39.4K Tons that last estimate had her as but I added a bit of armor and a slight better secondaries as they were available.

I like. Seems like a bit of overkill on the AA guns however. When launched Hood only had 4 QF4" AA guns. In 1917 N-verse I don't think the threat from aircraft would be large to to point were this AA would be viewed as needed. I might try a smaller amount of AA but maybe with a few heavier guns, like 3 inch or 4 inch 50 cal. Some MG's might be nice to.

Nobody in my area accept realistically my French Ally has a huge amounts of Zepplins to worry about... I chose to go with a large amount of basically implaced heavy machine guns.   To be honest the range of these guns means they are revenge weapons they can effectively engage enemy attack aircraft after they have attacked.   To be honest a huge amount of light AAA in current tech is pretty much useless beyond 1000 Yards... ;)

I still think 20 is a bit much, but they are your ladies. Dress them how you will.

Im looking at trying to find a different AAA gun supprisingly I have good AAA tech and not so good AAA guns.  I might just put 4 3"/50 guns in HA mounts for Anti-Ballon work and get rid of most of 1" Half Pounder Guns.... of course as soon as 1920 rolls around and I get done talking to my Italian Allies they go right back on.....

That sort of thing make sense, its just with the 1917 laydown 20 HMG's (or BL, whatever they are) seems a bit overkill. After hearing about the rift war and the like, I would stuff some of them back on as well.

Woopsie.

*Restrains my Hood fanboyism*

She's much more like the 1941 version than the 1920 version of OTL HMS Hood; more AA, speed pulled back under 30 knots, thickened deck.

I see nothing wrong with her, except that she's, well, very big and expensive for what she is. 8x16" at 28 knots makes a deadly combatant, but it's shouldn't take 40kt to achieve.

(Is going to be spending all night trying to build an 8x16", 30-knotter that fits under the 35kt limit)

You can try but the problem is until you get the 1917 Engine Tech and the 40K HP Per Shaft you are not going over 30 Knots :)  With a laydown in 1917 that simply isnt possible.

[Ithekro]

Simple thing is that no one in Navalism seems to be as advanced as historical in all areas.  Probably because no one has the economic strength to keep up with the likes of Great Britain in early 20th century and certainly not the United States in the middle of the 20th century.

That and we've not had a real deceivive battleship on battleship action since 1900 that I can recall.

[ctwaterman]

The Closest we have come to BB on BB action was some of the recent New Swiss Old Battle Cruisers or Super Cruisers slugging it out with modern Battle Ships and that didnt turn out so well in the gun aspect of the fight.

Ok, Fixed the turret arrangements that Sam spotted and the AAA battery.

Not bad. You're only 3,189shp over the 1916 engine year limit.

[mentat]

has to be my favourite topic - i like the design - but think a bit light on the deck armour - esp. vs 14" and above

possible to slim down the Bunkerage (you need that much ? - and full load draft might be a problem?) or Firepower - make do with 15" or just 16 5.5s?

- anyway - whatever you do - can we have a picture  ;D

[Borys]

Ahoj!
Underarmoured. A Golden Twinkie waiting to happen, especially with those 12" barbettes.
And the deck is IMO a bit cramped with those ten per side secondaries.
I like the shell weight, more or less historical.
