Hello! Naval history fan here. I have been working on an Alternate Universe with a lot of points of departure, but most of them take place after 1900. So, I thought to put them in this thread. One of the greatest points of departure, however, is the formation of a continent in the middle of the Atlantic ocean known as Lavrunaria. Being my most alternate fleet out of all the alternate fleets I am creating, I thought to post this one here.
Synopsis of Important Departures
This is the most fictional of the navies in my Alternate History, provincially known as 'Frontlines'. There are a load of points of departure for it, which will be regaled at length, but the most important for the below fleet is that France fell to Fascism in 1934 and invaded the Netherlands and England in the late 1930s in an event known as the Fascist Crisis. Britain is severely weakened by the depression and is only able to resist the invasion because of fanatical resistance. After the French are pushed back to the continent, they begin to look seaward towards colonies in the Caribbean. The problem is the large nation in the middle of the Atlantic - the Confederation of Lavrunaria, which fancies itself an empire and has already taken over a good part of the Caribbean (including former French colonies) to shore up its oil reserves, as the Lavrunarian continent has little oil. For that reason, tensions build until the Franco-Lavrunarian War is declared in January 1943.
The Lavrunarians practically go at it alone, with very little assistance from any nation, besides their oil trading partners in South America and the Caribbean. Meanwhile, the French are joined by Fascist Italy and Fascist Spain. Thus, the enemies of Lavrunaria have a very significant fleet, since all three of these countries have entered into vigorous building programs with the collapse of the treaty system in the 1930s. The Washington Naval Treaty still took effect, albeit without the US, as well as the First London Naval Treaty, but the resurgence of France made the Second London Naval Treaty practically a moot point. This wasn't helped by the fact the Lavrunarians also rejected it.
(If you're wondering about Germany, they had a Civil War in the 1920s after a successful 1922 Munich Putsch. Eventually, the NSDAP were pushed out of Germany and a Centrist party known as the Blue Centrists took over the country, and still rule it at the time of the Franco-Lavrunarian War. The United States, meanwhile, joined WWI on the side of the Central Powers and was so soundly defeated that the government fell apart. Several nations then began to re-colonize the American continent, while some smaller states pop up there. More information will be revealed later.)
This is a work in progress. It is my first Alternate History Project. I will be updating it as I improve it. Thanks for any thoughts!
The Imperial Navy of the Confederation of Lavrunaria
Dye Ymperiskot Eskydredsforbunndahf Lavrunaria
Strategic Situation
My navy belongs to an Island Nation which is in fierce competition with France for dominance in the Atlantic ocean. Our opponents have a large, albeit non-homogeneous fleet of ships from several different nations, with varying abilities. However, all my opponents are on the European continent while I require imports of oil in order to continue the war. Furthermore, treaties with Britain, Italy and France have forced me to accept a lesser amount of ships than I would like, before their collapse in 1936.
Since my enemy has a large fleet of cruisers, destroyers, etc., my fleet has to be qualitatively superior to theirs. Furthermore, my fleet has been relatively small until around the First World War. This means I have no major capital ships from before 1914, and these capital ships will have to be modernized. The enemy fleets have a number of modernized vessels as well, but a significantly larger amount of new construction.
The Lavrunarian and British governments reached an agreement in 1931. This agreement had far-reaching consequences for the Lavrunarian navy. Controversially, the Lavrunarians were allowed to build two new capital ships before 1937. However, to allow this, the Lavrunarians had to accept a significant numerical inferiority in aircraft carriers and retain their numerical inferiority in cruisers and destroyers which they were forced to accept in 1922. The Lavrunarians were allowed to build 5 new aircraft carriers before 1937 and maintain a total fleet of 8 aircraft carriers. They were also forced to maintain a maximum of 280,000 tons of cruisers and 165,000 tons of destroyers, but with no limits on new construction. Auxiliaries, escort vessels and submarines are not affected by this agreement.
However, there is a six-year gap between the end of this agreement and the start of the war. This allows time for a reinforcement of the Lavrunarian fleet, but not for a significant amount of new capital ships.
The strategic goals of my fleet are as follows:
Capital Ships
Battlecruisers - Grohssezuumdoynmfeorseglhen
The closest Lavrunarian equivalent to the english word 'Battlecruiser is Grohssezuumdoynmfeorseglhen, which translates literally to 'large armored cruiser'. This word shows the direct lineage of the armored cruiser into the battlecruiser, at least for the Lavrunarian Navy.
Pre-Treaty Ships
The genesis of the Lavrunarian battlecruiser force were two classes of ships built towards the end of the First World War. The first class was almost entirely a foreign design - in fact, it was based off stolen plans for a German ship - while the second battlecruiser class was built with the extensive assistance of the British. The design for both these ship classes, however, were changed over time to make them unique to the Lavrunarian navy - the Patrik Vidar class was changed to lead heavy cruisers, while the Ubyrregnyr Aukusti class was changed into a commerce raider.

Treaty Ships
Because the Lavrunarians had voluntarily slashed their dreadnought fleet by turning six of their battleships into carriers in the 1920s, they were allowed limited new construction starting in 1929 of up to 90,000 tons of new capital ships before the end of the battleship holiday in 1932, despite the fact their battleship fleet had been decreased by nearly 160,000 tons. This contributed to the growing distrust of the treaty system in Lavrunaria and directly contributed to its rejection of the Second London Naval Treaty in 1937. In the event, the Lavrunarians searched for an extended period for suitable designs falling under the 35,000 ton limitation imposed by the Washington Naval Conference. Three ships were envisaged - two battlecruisers of 32,000 tons and a larger battlecruiser of 45,000 tons - as part of the 3-3 Naval Plan, which called for three new battlecruisers and three new battleships. The Lavrunarians were well aware this broached their allowed tonnage limits but did not plan for their third battleship and third battlecruiser to be complete until after 1937.

Post-Treaty Ships
Since it was obvious the Lavrunarians would not accept the Second London Naval Treaty, treaty-breaking ships were under consideration even in 1933. This work, inspired by British ships, resulted in the Ubyrregnyr Ferdinand Kaes class. Orginally, only one ship was to be completed, but the second ship - Ubyrregnyr Adolf Oskar - was also ordered in the 1935 Fiscal Year in order to complete the new naval plan, 5-4, which called for five new battleships and four new battlecruisers. Similarly to the Ubyrregnyr Aukusti class, these ships were primarily commerce raiders. With the completion of the Ferdinand Kaes class, the Lavrunarian Navy now had a set of four extremely heavy and long range raiders designed to act in concert and capable of tying down significant naval assets in their pursuit.

Ocean-Going Destroyers - Ookeanitraaleritel Jagtyhhryn
The Lavrunarians refer to large destroyers meant to operate with the main battle fleet as Ookeanitraaleritel Jagtyhhre - translating literally to 'Ocean-Going Destroyer'.
Grohssetypp Ships
The first Grohssetypp ships reflected the Lavrunarian’s interest in Japanese Destroyer Doctrine, which had massed destroyers performing night torpedo attacks upon enemy battle lines. However, because the Lavrunarians expected their heavy cruisers to be the main vessels of torpedo attack in fleet engagements, the destroyer was not seen as being the integral vessel for this purpose. For that reason, Lavrunarian destroyers were more balanced than their Japanese counterparts, retaining more effective anti-aircraft and anti-submarine defenses than comparable Japanese ships. That being said, the Lavrunarian and Japanese designs were extremely similar - the Lavrunarian Grohssetypp was equivalent to the Japanese Tokugata Special Type Destroyer.

The strategic goals of my fleet are as follows:
- Disrupt enemy supply lines. I will need a large amount of submarines and other raiding vessels to put a significant dent in imports to the enemy’s supply lines to force him to stop his war effort. The countries in question import a lot of oil not only from a resurgent Middle East which drive hard bargains, but also from the Caribbean and Far East; enough that, if that supply line can be cut, the war will be won.
- Protect friendly supply lines. I will need a large number of escort and ASW vessels to protect my supply lines from enemy submarines and raiding vessels. This is absolutely necessary for my continuance of the war.
- Spread enemy forces thin. I will need a few vessels to harass the enemy and draw their forces away from decisive points. This includes a sizable number of commerce raiders.
- Whittle down the enemy fleet before decisive engagements. I will need to destroy a portion of the enemy’s fleet before he engages me directly. This means I will need to have fleet carriers with aircraft that can destroy the enemy in harbor, as well as midget submarines. Furthermore, I will need scouting vessels to find the enemy fleet when it moves out of harbor.
- Harass enemy fleet on way to engagements. I will need fast vessels to harry the enemy before major engagements with torpedoes and gunfire. These vessels will also warn of the enemy’s approach.
- Defeat enemy fleet with superior vessels in decisive engagements. I will need superior capital ships to engage the enemy battle line directly after it has been whittled down by other forces.
