Wow, thats incredibly useful, thanks for posting. I had been mostly just finding ships of vaguely similar size to mine and upscaling/decreasing their power plants accordingly. Knowing for my submarines the actual numbers that I can use to get the appropriate propulsive machinery and the performance will be an incredibly cool. Thanks for finding such awesome information and being kind enough to post it in a manner that is easy to understand and highly informative.

This might be can be of some use. Though sorry it's kinda disorganized.

Thats incredibly useful too, I don't think its disorganized at all. Sure it has a long post, but the beginning section helped to clarify it, and the information it had was an interesting diversion. I had been working on a Steam group's USSR 1950 navy and was planning on making their submarines eventually, I can use the information you provided for the dimensions. Maybe once I'm done I can TG you the design so you can show any mistakes I made? Although that might take a while to get to, although the submarines will naturally be the most important part of their navy I am so bad at designing them I'll be going through the rest of the ship classes first. Thanks again for the informative post on the subject.

You're welcome. Glad to see it's useful.

Anyway i'm still continue to refine accuracy of those information i posted here..So there will be updates.

The Republic of Atapolis created its naval division in 2020, exactly 5 years after the foundation of the republic.
Akula submarine dominates the arsenal of the naval divison, as there are 5 units of Akula sub available for combat.

Aside from the typo, what surface ships does your navy operate? What other vessels other than nuclear submarines are in use?

remove spaniards

I feel like it isn't a good idea to have two elevators opposite each other like that. I feel like it would reduce your ability to carry out flight operations (such as landing) given that together they take up a good bit of space. Additionally they look so close that they would get in one anthers way.

You think so? I haven't really done any work on the hangar, as this is mostly for aesthetic purposes. Would shifting the elevator forward help, or should I consider widening the ship, perhaps?

As Spirit of Hope said, I would space out the elevators a little bit, think about it this way, if one elevator was to get hit by a cruise missile maybe, you run the risk of both elevators being put out of action.

Wouldn't a missile hit put the whole flight deck out of operation anyway?

Not necessarily, depends on the missile, where it hits and how good your damage control parties are.

I suggest you start by marking out where the landing and takeoff areas are going to be, as they're the absolute necessities for a carrier to function; once that's done, you can move on to add the elevators where there's room. Unless this carrier is STOVL, I don't see where the planes are going to land.

Honestly your entire rear end looks weird. Take a look at some real life carriers, often their rear end is as larger, if not larger than, their front. This is because taking off only really happens where you have either a catapult or a ramp, which means you get set up at a point and just go strait. Landin can be trickier, in part because the pilot can't judge well where he is landing, it in part requires someone to guid him down. So you want to make landing as easy as possible.

Additionally looking at carriers, I only see one that has elevators on both sides, most have two elevators on the same side as the tower, with the other side essentially just being a bunch of runway. Any "waste space" on the side without the towers is used to store aircraft before they might take off.

NSS Ripatoire

The extraordinary logistical costs of projecting power to lands thousands of kilometers away was a problem that could only be solved through millions of gallons of bunker fuel and hundreds of tanker ships.

However logisticians aptly paid attention to the claims of various nuclear physicists, who after some funding, built a functioning nuclear reactor in the 40s after the discovery of nuclear fission on 1938. The reactor did have design flaws, and the process in refining and processing nuclear fuel remained experimental, but the ground work was laid for a early nuclear reactor.

In order to compensate for the complexities of refining uranium, graphite and heavy water would be used to allow for the use of natural uranium. There was an additional advantage of this approach, as a last ditch effort in a criticality incident, sea water could be pumped into the core, which would poison the neutron-based chain reaction.

Still, designing such a large reactor still had issues. Despite a conservative approach to design which gave the reactor a power density below that of later reactors, the flow of coolant was less than efficient, reducing output further. The reactor provided the first steps to modern nuclear design.

The widespread deployment of the atomic bomb also meant that armor can no longer be relied upon as a defence, even in gunnery duels.

Already obsolete as the keel was laid down on 1952, the Ripatoire class continued to be budgeted for completion.

[New Vihenia]

Hmmm Still refining my Submarine sizing equations... This time i have filled some data points and equations for following type of subs :

-Transport submarine (yay Submarine LST)
-Tanker/Cargo Submarine (Container carrying submarine OR liquid payload such as oil)
-Single hull military submarine (SSK,SSP,SSN and SSBN)
-Double hull military submarine (SSK,SSP,SSN and SSBN)

Well basically provide more options and some "distinctions" For submarine types.

Here's the resulting curves as well as their respective empirical relationship.


Larger version-------------->HERE

Usage is basically the same as what i previously described Here

But to find submarine surface area, one may change the "Surface area constant" From 2.8 to 3. I found that factor of 2.8 somewhat provide under-estimate of modern submarine's surface area, especially with advent of pumpjet propulsor which will increase surface area due to addition of shroud.

And just that, aside from new empirical relationship :

Single Hull Military Submarine :
Sd=0,0649*Sa^1,4033

Double Hull Military Submarine :
Sd=0,0237*Sa^1,505

Military Transport Submarine :
Sd=0,0003*Sa^2-4,6206*Sa+26806

Submarine Transport/Tanker
Sd=64915ln(Sa) - 572273

Where :
Sa=Surface Area in square meter.
Sd=Surface Displacement in metric ton.

Hmm from above.. i make simple estimate of SSN-774 Virginia class's surfaced displacement, the result was 6178 or say 6200 metric ton. Hmm it's kinda unusual for US Submarine i see, because with submarged displacement of 7900 ton it will provide reserve of buoyancy of 27% Larger than Previous US Submarine, even larger than SSN-21 with RoB of 23%

She can tolerate more flooding than LA or Seawolf.

Thoughts are welcome. Would love to see though if anyone have better data sheet.

[Rich and Corporations]

it's a simple square-cube relationship?

[New Vihenia]

it's a simple square-cube relationship?

No. It's linear regression/curve fitting or whatever done by compiling data in excel, plot graph, press right mouse button then choose "add trendline" option.

The R squared value there is Coefficient of determination to see how well the data fit the equations.

Hmm not really tell the whole stuff maybe but i think it's adequate for now.

[Pharthan]

Sub nuclear plant sizing. Repost i think.
Ok. Let's start :3

Submarine Nuclear Power Plant Sizing.- Conceptual Stuff.
-Snip-

Nice.

Copying to text file. Good pics. Will likely include some of this in my "Reactor Design" article on NS Draftroom, since it's mostly Reactor Theory right now, and I'm not as good with the Machinery Room side of the house.
I'll make sure to quote you/the source.

Ensure to add other auxiliaries. A good 20-30% of the size of the reactor plant is just stuff to keep the reactor running, not propulsion at all.
Also, not sure if anyone's pointed this out: You never just have one boiler for a reactor. You have multiple coolant loops.

[Chebucto Provinces]

A few changes.

The Royal Chebucto Navy has a long and proud maritime tradition. Established as an independent offshoot of the Royal Navy in 1862, it has been conducting operations primarily in the North Atlantic ocean ever since.

As of 2014 the navy sits at 55 ships and 21,067 personnel. The bulk of the fleet is based out of Halifax Harbor, stationed at one of three fleet bases within the harbor. There are also two outposts at Sydney and Yarmouth which have a small permanent force and accept rotating deployments from Halifax. The bases in Halifax Harbor are Stadacona, Eastern Passage, and Bedford. In terms of manpower the RCN is the largest branch of the Chebucto armed forces.

The core of the fleet are two aircraft carriers of the Hall Class. Developed for the RCN in the 1970s in France, and first in service in 1981, the two ships are similar to a modified Clemenceau class, with a lengthened landing strip to enable operations from F/A-18 Hornets.
- HMCS William H. Hall (Commissioned 1981)
- HMCS Provo W.P. Wallis (Commissioned 1983)

The current backbone of the surface fleet are the Valley Class guided missile destroyers. Six ships are in service, having been built by Irving Shipyards in Halifax from 2000 through 2005. A planned major refit starting in 2018 will include a new combat system developed from the Aegis system.

- HMCS Annapolis (Commissioned 2003)
- HMCS Canso (Commissioned 2004)
- HMCS Chedabucto (Commissioned 2005)
- HMCS Cobequid (Commissioned 2006)
- HMCS Musquodoboit (Commissioned 2007)
- HMCS Shubenacadie (Commissioned 2008)

The Valley Class replaces two older classes of ships, the six ship Beach Class Frigates and the four ship Island Class Destroyers, which were all retired by 2011.

Additionally there are sixteen Corvettes of the Province Class which operate primarily in a coastal patrol role. The Province Class ships are capable of operating independently in the open ocean, close to shore, or as part of a task force in support of other ships. They are named for the sixteen provinces of Chebucto and were commissioned from 2004 to 2014. They are:

- HMCS Antigonish
- HMCS Colchester
- HMCS Cumberland
- HMCS Digby
- HMCS Guysborough
- HMCS Halifax
- HMCS Hants
- HMCS Inverness
- HMCS Kings
- HMCS Lunenburg
- HMCS Pictou
- HMCS Queen
- HMCS Richmond
- HMCS Shelburne
- HMCS Victoria
- HMCS Yarmouth

The Royal Chebucto Navy also operates seven submarines. All seven submarines are a variant of the TR-1700 class submarine, all built in Germany and entering service between 1994 and 2001.

In addition to combatant ships, the RCN maintains three large replenishment oilers in service. The Provider Class oilers have been in service sine the mid 1980s. They are due to be replaced starting in 2018 with the new Preserver Class oilers, of which three ships have been ordered. The RCN also operates four 45 tonne displacement tug boats, and three 250 tonne displacement tugboats. Three training and patrol vessels of the Bridge Class have been in service since 2005. A fleet of six mine countermeasure vessels are also maintained.

Amphibious capability is maintained through the use of one LPD, HMCS Jean-Louis Le Loutre which was acquired as a new build from Italy in 1998. Three Drumlin Class landing ships have been in service since 1980. The RCN maintains a cadet training schooner built as a copy of the original Bluenose fishing schooner as the HMCS Bluenose.

In terms of organization the RCN is divided into three major subdivisions: the Surface Fleet, Submarine Fleet, and Support Fleet. The Surface Fleet consists of both aircraft carriers, all Valley class destroyers, and all Province Class corvettes. The Submarine fleet consists of all submarines, and the non-combatant and amphibious warfare ships are part of the Support Fleet. All three fleets are headquartered at Stadacona. Both carriers are independent and based out of Eastern Passage, near their airwings at Shearwater Aerodrome. The Submarine fleet is based out of Stadacona, while the support fleet is based out of Bedford.

The Valley Class destroyers are grouped into a single Destroyer Squadron, which is based in Stadacona. Both Yarmouth and Sydney host temporary rotations of up to two Valley Class ships throughout the year.

The Province Class corvettes are grouped into two squadrons of eight ships, KS1 and KS2. KS1 is headquartered in Yarmouth, while KS2 is headquartered in Sydney.

Combat formations of the fleet consist primarily of Carrier Groups formed around one of the two carriers. These will usually consist of the carrier and its airwing, two Valley Class destroyers and one or two Province class corvettes. An oiler is often seconded to the group.

Standard weapons of the RCN include the Oto Melara 127/54 compact, Oto Melara 76mm Super Rapid, Denel 35mm DPG and various small arms. The RCN also employs the VL Mica and the SM-2 Standard Missile family.

[Padnak]

The Republic of Padnak is a large collection of islands spread over massive area and its primary defense concerns are territorial defense , anti smuggling (a major problem) and support of ground forces fighting against insurgents on many of the smaller islands.

If you guys could assess my navy and offer some pointers on how to improve it in its role that would be excellent

Cool.. Thanks a lot I'll make sure to add it. Guess it's those things like control rods drivers and other stuff like hmm water and oxygen distillating plant.

And yes..One can have multiple loops for a reactor .
