Catholic Class Super Dreadnought (SDN+)
Picture of Catholic Class (http://img254.echo.cx/my.php?image=experimentalbattleshipmkii0nd.png)


History: Long ago, the last of Stevid’s capital battleships was dismantled. The renowned Akira Class Battleship/Dreadnought was the pride of the Stevid nation and navy. It was built when Stevid first entered the OMP and proved itself to be in the early years of the OMP to be a formidable ship. It was also designed to be as quick and as powerful as the Doujin class dreadnought. The most sought after and most powerful battleship of it’s time. Feared across the world many nations decided to build their own battleships and dreadnoughts to “combat” the Doujin designs.
A long time has passed since those days, the Doujin isn’t what it once was and many of the Super Dreadnoughts dwarf the Doujin Class and the Akira looked at of place and obsolete. A new battleship had to be developed. Stevid BAE Systems got to work on the experimental Domination Class designs. Domination was still only a battleship and not much more powerful than the Akira Class but it was the only thing they had. To make things worse, nearing the completion of the prototype, Guffingford and many other nations decided that now was the time to bring out their brand-new Super Dreadnoughts and line them with powerful armour. Obviously this left Stevid at an enormous disadvantage. Stevid now had one of least powerful navies in the world despite the re-design and re-organisation of the whole navy. It was a monstrous turn around and RN Stevid needed something, huge, powerful, and quick and something to be feared. Stevid BAE Systems got to work on their own version of the Super Dreadnought Class. It has taken a long time and numerous delays but the prototype has been completed and the specs have been released. But the blue prints, and essential stats required to actually build the ship are under lock and key and fiercely protected by the best security forces in the whole of Stevid.

This Super Dreadnought is not for sale until it has been successfully integrated into The Stevid Royal Navy. However, power and money does corrupt everyone. We are only human… In time the Stevid Government will put this ship on sale and the basic plans may be sold at high expense other nation’s shipyards so they can begin their own construction and be sold separately.

Looks good but the displacement is way off. You should have over 1.5 million tons.

Yeah, the displacement is closer to that of a Yamato-class battleship than a SD. Not only is the displacement off, but the beam needs to be at least 100 m wider. I'd also recommend at least 5 m deeper draught.

The armament is also very limited for a SD. The 30 inch gun is a bit too heavy, slower-firing than guns of slightly smaller calibre, and after approximately 24 inches, range and accuracy decrease. Many of the newer round of SDs use 30 inch guns primarily for "political" purposes (in other words, as an intimidation measure).

The number of VLS cells is also weak in comparison to other SDs. The Doujin has over 2,000 VLS tubes while the Vigilant has roughly 384 VLS cells. You may want to use VLS cells that are capable of firing more than one type of missile. The secondary armament also *must* improve. You need something like 6 inchers or 8 inchers to deal with close-in threats.

The propellers would be seriously overworked, and it is doubtful the ship could safely do three knots, never mind thirty.

Thank you for your contributions people and in perticular to yours Sarzonia. I completly forgot to add seconadry armament.

As for my VLS tubes I will shove some more on, but 4 are designed to throw nuclear missiles at a target,it is pretty deadly.

I am afraid it has been slightly rushed, this. I've had a good load of exams and other stuff to do.

None of you said anything about the armour which i'm glad of. I'm no good with armour and it took me ages to find all that stuff out and so i'm glad there's nothing wrong with it.

A couple of things and then this will be quite good -

1) More guns. Four 25" guns is the lightest armament I've seen on a dreadnaught, and this is almost as long as a Doujin (which mounts 20x 30" guns).

2) More VLS cells. For something so lightly armed in guns, it doesnt have an imrpessive number of VLS cells either.

3) I highly doubt that your jamming systems are 97% effective.

Otherwise quite good. Maybe add more planes, or reduce the overall size.

WOW!!! Praise for my naval work coming from Praetonia!! The nation with one of, if not the most, powerful navies in the NS world...

Thank you, i'll take heed of your advise, however there is a slight contradiction. Sarzonia said that 30" guns were too big for me so I took them off.

so..

1)I'll put the 30"ers back on an put a few more (but not lots more on). And i'm working on the seconardy cannon armament which should be finshed by Sunday (If I find the time).

2)I'm struggling with that and i'm sorting it out, i'm currently snooping around looking at different types of missiles that can be launched vis VLS.

3)97% was the percentage when it was tested. I don't know how effective they'll be against an opposing nation's ECM/ECCM stuff. A guess would be ranging between 67% and 82%.... Just a guess.

Thanks again.

Sorry, I didn't mean bigger guns I meant more guns. 25" is fine, but 4 is not. I should have specified.

Well anything can, provided the VLS cell is big enough. Unless you want to use solely RL weaponary I s'pose.

I don't know an awful lot about ECM, but I claim about a 95% success rate for my entire anti-missile defence initiative, which includes countermeasures, decoys, CIWS guns, arsenal ships full of SAMs and all this guided by supercomputers that compile all the sensor information from an entire fleet located inside superdreadnaughts, so meh.

Thanks again.
You're welcome.

Not your fault at all old boy, just a misunderstanding on my part. Thanks for the rest of the info though.

But remember that I forgot to put the seconadry cannon armament so that'll be put on sooner of later.

Well anything can, provided the VLS cell is big enough. Unless you want to use solely RL weaponary I s'pose.

I use RL.. RL is good but i've got my own missiles as well. (Check my SDN's missile armament), make newer ones looks like the next step.

Thanks again.

I like the overall design and stuff, but I agree with everyone else. Also, while looking at your image, I noticed that your layout is severly flawed. Currently, you have a turret at the very stern of you ship. That baby's gonna have her bow out of the water, in fact, she'll sink tail first. You might want to add some length to the stern to balance it out 'fore she keels over and dies on ya.

BUMP

Yeah I see your point, it is a bit too far back.

I can see all the flaws and I intend to sort most of them out today, the seconadary armament in perticular.

Thank you any way.

BUMP

Armament changes have made and the picture has been modified.

This is a nice looking vessel, we need a ship to support our Iowa class battleships, and so eagerly await the announcement of the cost of this ship.

Neuvo Rica, If your gonna one of these things then you might as well scrap the Iowa Class.

We will anounce the Estimate cost of this Super Dreadnought in the very near future. You will be TG'd on any developments upon the cost since you are interested.

BUMP

Price TAG now added.
Anyone interested then please place an order and/or construction rights.

(Rights may cost extra in terms of mass production).

I hope your sailors have a good health insurance 'cause this ain't healthy:

OOC: How do u guys design your ships? You use a program or sgo by knowledge?

I may not know what all the numbers mean, but the picture is nice.

(Gives it his Stamp of Sexiness Approval(TM) )

credonia, i go out there, find papers, documents, reports, read up on a lot of stuff, spend quite a few days working out basic requirements and needs, then start compiling it into a workable design from freehand drawings to rough-draft descriptions. When it nears completion I use Paint to draw it, itself a time-consuming operation, then I save the final draft of the description and hope I never have to use the damned things...

so i do them by my own knowledge, although I imagine there has to be a programme out there should you want it... i just prefer the old-fashioned method...

and to you stevid, since i don't want to hijack your thread and such, i know you say you're using six shafts for propulsion, however, the English reads as if your six reactors are connected to a single shaft, unless in my exhaustion I'm simply not reading that properly. outside of that, not commenting on the picture (for which the aft seems out of balance to me, but that's just my two cents), everything else appears to be coming together... although i would like to comment on the primary gun systems, if i understand you correctly you're using six quintuple turrets for a total of thirty guns?

my only real... not a problem as i imagine it's certainly technically feasible, would be that a lucky shell to land and knock out that one turret could do... significant damage... heaven knows how awful it would be should someone manage to make it down to the magazines for those guns. admittedly, the SD i've been many weeks in the planning uses quadruple turrets, and i've caught a lot of flak telling me to reduce them to triple turrets for similar reasons, plus the always popular rate of fire and distance arguments. so i'd just like to point that out if you're not already aware of it... if you are, my apologies and just continue on... if nothing else, you've spurred me to keep working on my bloody SD...

Well the issue with quadruple turrets is that;
1) It means that if a turret is hit you loose more guns
2) the wider turret is going to cut down on internal space, and limit both the weight of the turret armor (the turret is already massive to begin with but adding a 4th gun you add 25% more weight which is most likely going to come out of the turret armor, as the barbette will actually have to be reinforced to handle the strain and again... more weight with higher vulnerability)
3) Most people are unaware of this but theres a reason battleships fire in a staggered fashion and not all at once in a true combat action. The reason is air disturbance; the bigger the round or the higher the velocity means that if you fire all your barrels ona turret at once the inner pair will be forced together (into one anothers or way of course which can have bad effects for any friendly ship in the area) and the outer pair of rounds will be sent wide which kills accuracy. IF you still want to fire a constant broadside the only method ive seen was used ona british cruiser (class I dont happen to remember) which mounted its middle of three guns almost a meter farther back then its side guns allowing for a broadside to be made with no staggering or delay... but of course that was a 6" gun not a 25" so im guessing a subsequent method would require 2 or more (im guessing 3 to 4 honestly) meters to prevent such an effect from the larger rounds.

EDIT: quintuple turrets will have the same problems except increased... however... with 5 turrets youd be able to set back two guns with no interferance... which I suppose is a benefit, I still think more turrets or less guns would be the best use of space, after all the guns are good but youll get a much better cost benefit and range to effect ratio from heavy or super-heavy anti-shipping missiles than most guns.

To The Island of Rose: Thank you. I didn't know my art was that good.

To Azazia: I comend people who point out something that's wrong with some things, It shows they're full of good will. The reactor thing powering one shaft, is a typing error and I haven't got round to changing it. You mentioned the stern being mis-shaped, well that bloody stern is causing me so much trouble that i've just left it. From now on people have gota use their imagination.

Azazia and Mekgui: About those turrets and their barrells. Thanks for pointing that out and i'll take a closer look at them.

To Credonia: That Sharppoint thingy is alright. Thanks for bringing that to everyones attention.

We would like to purchase 5 of these ships, as part of the massive modernisation (and move away from soviets weaponry) that our navy is undergoing. We would like to purchase 5 Catholic class super dreadnaughts for £775 Billion.

Neuvo Rica.

I'm gonna TAG this, pending my own design based somewhat off of this, and the comments that are here.

Neuvo Rica.

Mass production has already begun and so your order has been confirmed Neuvo Rica.

The Super Dreadnoughts will arrive to you soon. Thank you for purchasing.

OOC: Good design man....when are you going to declassify the classified stuff?

OH MY GOD!!!

Is this thread still around?? I thought it had died ages ago...whoa, doesn't time fly?

The SDN is already intergrated into the Navy and so this thread has VERY, VERY little meaning now. But the classified stuff will not be disclosed untill the ships reach the near ends of their lifes. But thanks for the.....rather late complement.

Jeezz still can't believe this thing is still around.....

OOC: I see. I liked the ship, so I was considering of having some to form my (unfounded) SD fleet.

Stevid would be nore than willing to help found your own SDN fleet of ships. Help with designs, weaponary so forth using the Catholic Class.

OOC: Contact by TG if you want and we'll take it from there
