The Nation;

[ img ] [ img ]

Sieran, or the Socialist Republic of Sieran, is a large, socially progressive nation and is the most northeasterly region of Eurasia. In history it is often known by its historical provincial name as Chukotka. It is bordered to the north by the East Siberian Sea and the Chikchi Sea, whilst to the east it is bordered by the Bering Sea. Sieran also shares land borders with the Sakha Republic, Magadan Oblast and Kamchatka Krai. The country consists of Chukchi Peninsula and some of the small islands that can be found in the Bering and Arctic seas. Due to its proximity to the Bering Strait, Sieran has long controlled this passage into the Arctic Ocean from the Pacific Ocean.

Sieran is a Social democracy with a Parliamentary system of government. Sieran has a state-level government and provincial governments in 8 provinces. Sieran is not a member of any economic and political unions though it is currently considering available options to do so.

Sieran, with a Social market economy and a large Welfare state, ranks as being in the top 5% of the world for happiest and most cultured citizens as well as lowest crime rates. Sieran is also ranked in the top 10% of the world for smartest and healthiest citizens. The national languages are Russian and English with a rich combination of other languages and cultures within its populated areas.

Sieran is often considered to be a regional power.

The Navy;

The Sieranian Republic Navy came about as a result of the acquisition of former Imperial Russian Navy vessels after the Revolution and the gaining of Sieran's independence in October of 1905. The vessels that formed the embryonic SRN were for the most part obsolescent vessels that had been lucky in surviving the slaughter of Tsushima. These vessels consisted of a single Protected Cruiser and three old Destroyers. Subsequent efforts saw the raising of a scuttled Pre-Dreadnought Battleship which was patched up and commissioned as the flagship of the new navy

The immediate years following saw little development in the SRN. Sieran had little funds available to spend on the ships and the Navy slipped further and further into a neglected state of disrepair. This all changed 1910 as Industry and the Economy began to recover and money started to become available to the Government.

By this time, the old Coastal Battleship had been retired into training operations and the Protected cruiser was far too old to survive a modern engagement. This left just the three Destroyers, of which only one was operational. A major building program was undertaken which saw these old vessels decommissioned and replaced by newer, modern fighting ships which had a heavy influence from British and German designs of the period.

It was decided early on that all initial construction work should be dedicated to the construction of a fleet of Destroyers and Light Cruisers that could protect the nations' rapidly expanding trade routes with foreign nations. The keels of the first heavy cruisers were lain in the early months of 1912.

The Navy now had a new doctrine which consisted on the idea of 'Aggressive Defense'; having a fleet capable of taking a fight to the enemy away from national waters. In order to establish this, a vast recruitment program was enacted and the initial steps were taken to build the first of the new dreadnoughts. Plans originally called for five such vessels but this was cut down to two due to budgetary constraints in 1914. In the same year in acknowledgement of the growing usefulness of Aviation, a merchantman was taken over by the Navy for conversion into an Aircraft Carrier.

By the start of the 1920s, Sieran could boast a strong Navy that compared favorably with many other similar-sized nations and even some of the older European powers. During this period of relative international ease, the Navy saw little in the way of development other than the gradual increase of its size and vessel types, allowing it to perform a greater variety of missions.

The 1930s saw tensions beginning to rise throughout the world as a new Arms Race began. Sieran, unable to fully compete was, for the most part neglected by the other world powers with the exception of the Empire of Japan who saw the potential of gaining access to needed resources through the nation. A second major naval expansion was begun in 1936 which saw the design of new vessels and large production orders for ships of all kinds.

By 1938, The Sieranian Republic Navy had a new class of Battleships being constructed as well as the construction of a new, larger Aircraft Carrier to replace the now obsolete and too slow original conversion.

Below I'll post the designs of vessels in the fleet as of 1938, though their may be multiple versions of ships to reflect class upgrades and modernization. Help with the springsharp stats as well as the images is welcome.

As I've long ago completed the design for the Markovich class Battleships (still under construction at the time I rp, 1938), I decided to go back and design the predecessor class of vessels.

The idea behind these ships was for them to replace older ex-imperial Russian navy vessels still in service with ships that could potentially compete with any enemies that might contest Sieran's vital maritime trade routes, the most potential enemy being the Empire of Japan.

Sieran itself only has a few highly-skilled designers but foreign aid was brought in to design these vessels, the United States in particular thanks to favorable relations between the two.

The ships main operational area would be the Bering Strait and North Pacific ocean so the ships have strengthened hulls to deal with ice conditions and an experimental clipper style bow.
The only innovative feature of these ships is their turbo-electric drives which provide better throttle response and power to weight ratio whilst occupying smaller space.

Anyway, here is the stats generated in Springsharp which I think are okay.

First thing that strikes me is that all the superfiring turrets are very close and turret b is very close to the superstructure

It looks suspiciously close to Midnightnova's Maryland...

I haven't seen that before but I've been basing this ones hull shape off of the New Mexico class without the casemate mountings and crossing it with Derfflinger-style upper works.

Been a while but here is an updated version of the Anadyr WIP showing some more work done. I spaced out the main guns a bit more and re-did the upper works as I didn't like the originals much. Still need to work out where I'm going to place the secondary guns and the ships boats.

The E I Class Submarine was the first home designed and built submarine to enter service with the SRN. The E I class is primarily intended to act as a scout and coastal defense vessel mostly within the Bering Sea with possible use in the North Pacific against IJN vessels (if war was to arise between the two nations which is possible as tensions are high).

This particular class is small and relatively lightly armed with two 21' forward torpedo tubes and a single aft tub firing between the twin screws. They have a diving depth of about 100ft and a max surface speed of about 14-16 knots. Not sure of the precise construction date yet but the craft are supposedly the predecessors to the later ocean-going C Class submarines which entered service in 1938.

The second image shows one of the later experimental schemes of the 40s worn by E I Class submarines when the Sieranian Republic Navy was experimenting with ways of concealing a submerged vessel from aerial detection.

Updated the thread title and the first post to include information about the nation and the history of its Navy as well as providing a map showing its location and geography and links to the external resources I have been writing.
