VM - Navy

The Navy is naturally one of the biggest assets of the Laywenranian Defense Force. Service in the Navy is viewed as prestigeful and generally, the Navy becomes the largest part of the defence budget.
The main tasks are Recon, Patrol and Convoy Escort.

Equipment

Ships

The ships are divided into the following classes:

The English terms are not necessarily literal translations, but use the common classification of ships in the English speaking world.

Armament stated here as equipped at the end of the third Cataclysm, which generally features heavier AA-weaponry then at the outbreak of the Third Cataclysm. It is noteworthy, that nearly all modern Laywenranian ships were equipped with Diesel engines, the exceptions are the older battleships. Laywenranian design school usually placed a big emphasis on durability and stability over firepower. This approach leads also to strong underwater protection, which is a major design feature in Laywenranian ships even today, after the experience from the Second Cataclysm, where many ships were damaged by mines and torpedoes and rarely by gunfire.

Torpedo Boats

S-Klasse

Development of the S-class began immediately after The Second Cataclysm. The navy formulated the requirement for a cheap, small and fast motor torpedo boat, capable of attacking large enemy ships intruding in the Laywenranian archipelago. Multiple shipyards proposed designs, all of them mounting 2 torpedo tubes, being powered by petrol engines and achieving speeds in excess of 40 kn. Following lengthy trials, new requirements were formulated, requiring the use of diesel engines and the addition of at least one heavy machine gun. The decision to adopt diesel engines wasn't welcomed by all departments - the lower power density necessitated either a bigger ship or less speed - both options deemed unfavourable. Yet the construction department insisted on the adoption of Diesel engines on these ships mainly for three reasons: it gave a greater range due to better fuel economy of the diesel engines, the danger of fire was lower and - probably most importantly - they wanted to accumulate experience with diesel engines to adapt them for bigger ships. The MAKO SD150 diesel engine was specially developed for motor torpedo boats and developed 745 kW per engine, propelling the ships to a speed of 50 kn on a calm sea. Due to their limited size, they had only limited seagoing capabilities and had trouble in higher sea states. The ships were equipped with 2 radio sets - one medium wave for communications with shore installations and the headquarters and an FM set for communications with the ships of the flotilla at sea. Armament consisted out of two rear-firing torpedo tubes as well as a heavy 13 mm twin machine gun on a platform behind the bridge. 15 boats were built from 1927 to 1932. The apparent limitations of the design led to the development of a bigger successor. Despite these limitations, they were viewed as an important addition to the fleet in the early build-up years.

G-Klasse

The G-class was intended as a more seaworthy successor to the S-class boats. The displacement significantly increased, which enabled the ships to mount a heavier weaponry. They were generally viewed as a successful design. 28 of the boats were introduced into service from 1930 to 1935.

I-Klasse

The I-class of torpedo boats was intended to supplement the earlier G-class. While they had two torpedo tubes less, they proved to be more seaworthy and had an armoured bridge (15 mm of steel) to protect against small arms fire, especially from enemy planes. About 50 of them were built during the war.

Destroyers

Naluca-Klasse Torpedeur

Originally planned as escort ships, the final design was altered to a torpedo boat, reducing the number of depth charges for mounting a quad torpedo launcher mounted on the centre line of the ship. Two of the tree 80 mm guns were mounted in the rear of the ship in open mounts, while the third gun was mounted in front of the bridge, equipped with a shield to protect against the weather. They were originally intended to attack the enemy battle formation during night battles to wear them down, therefore possessing a low silhouette and good seakeeping ability, but ironically, later on, they were mostly used in the Laywenranian archipelago to escort convoys. During 1938, one of the 40 mm guns was landed, being replaced by two 25 mm/70 md. 31 guns. Some of the surviving ships landed the torpedo mount, its place being taken by either a single or a twin 40 mm mount. They later received FuMo Typ 32 radar sets which were available due to their replacement by more sophisticated radar systems on larger ships.

Livia-Klasse Torpedeur

The Livia-class was essentially a slightly enlarged Naluca-class. Displacement and dimensions increased due to the mounting of three 100 mm guns in lieu of the 80 mm guns of the Naluca. Otherwise, the design was essentially the same. During the war, the ships were used as escort vessels for convoys as well for the fleet.

Mary-Klasse Torpedeur

The Mary-class was intended to supplement the previous Naluca-class in the initially intended role as an escort ship. The guns were mounted in twin weather-and-splinterproof turrets, improving the work conditions for the crews in harsh conditions. The displacement was increased significantly to mount heavier weaponry and to increase the stability. The bridge, the engine room and magazine deck were armoured. A total number of 30 Mary-class ships was built, but only the T-12 Mary received a name, all other ships were only assigned a number.

Loredana-Klasse Kontertorpedeur

The ships of the Loredana-Class were obtained shortly after the independence and the Second Cataclysm. Beeing rather new ships at this time, they were thoroughly modernised in the 1930s. Originally equipped with the 120 mm/50 md. 20 in five single mounts and four 80 mm/40 md. 17 as anti-aircraft armament, they were modernised with 5 x 120 mm/50 md. 32 in two turrets and one single mount, landing the 80 mm guns and replacing them with four 40 mm/60 md. 28 in single mounts. In 1938 the single 120 mm gun was landed and replaced by three twin 25 mm/80 md. 31. The single 40 mm guns were later replaced by 40 mm/70 md. 35 guns in twin mounts and two additional 25 mm twins were placed in the bridge wings.

Sakura-Klasse Kontertorpedeur

The Mara-class served as a further evolution of the design of the Loredana-class. The Sakura initially had 5 single 120 mm guns but they were soon replaced with 4 twin mountings, the vacant place of the fifth gun behind the last funnel being taken up by a 40 mm mount.

Tali-Klasse Kontertorpedeur

The design work for this class started in 1931, intended to provide a larger type of destroyer, which could fill the perceived gap between the Marasti-class and the light cruisers. They ended up as the most powerful destroyers of the Third Cataclysm, almost rivalling older light cruisers in firepower. With their good stability and fire-control systems, they were widely regarded as a success.

Cruisers

Mariko-Klasse Spähkreuzer

The Mariko-class was the first indigenous cruiser built by Laywenranian shipyards. The design was based on contemporary foreign cruiser designs, but the equipment and armament were produced in Laywenrania. The magazine and machine space had 80 mm of armour and an armoured deck of 30 mm was introduced. The conning tower had an armour thickness of 100 mm. While they were originally intended as scouts for the fleet, they were made redundant in this role by shipborne aviation and the event of radar systems and its widespread introduction on ships. Therefore they faced an extensive modification and converted into AA cruisers: The main guns were replaced by 100 mm DP twin turrets, extensive light AAA was added, the old steam boilers and turbines were removed and replaced by Diesel engines and radar were added.

This class was the second type of larger ships built in Laywenrania. With a drastically increased displacement compared to the Mariko-class, this class was seen as proof of the capabilities of the Laywenranian shipyards. They were viewed as quite successful designs, with good seaworthiness and a powerful armament and sufficient armour. 70 mm belt armour, 90 mm magazine box protection, 30 mm turret protection, 25 mm deck protection.

Ainsley-Klasse Spähkreuzer

The Ainsley-class of light cruisers (still called scout cruisers by the navy, althoug their displacement almost reached the dimensions of earlier heavy cruisers) was a further development of the Morris-class of cruisers. They had enhanced armour (100 mm belt armour and 50 mm deck armour) and AA defence (an additional 100 mm twin and more 40 mm guns). They were quite sturdy and stable warships, providing essential scouting, escort and fleet assets.

Muireall-Klasse Spähkreuzer

The Muireall-class of cruisers was a result of continuing pressure in international shipbuilding. The armour was again strenghtened, an additional 150 mm gun was mounted, as well as an additional 100 mm gun. With a maximum belt thickness of 125 mm, 80 mm deck armour over the magazines, 115 mm of turret armour and an emphasis on compartmentalisation, the ships were sturdy and could take quite a punishment for ships of their size - the armour exceeded that of earlier heavier cruisers by quite a margin. Together with highly modern fire control systems and radar, they were useful additions to the fleet in wartime. Due to using the same engines despite the increased displacement the speed dropped slightly.

Alisa-Klasse Panzerkreuzer

The Alisa was developed as replacement for the Valentina-class. While retaining the same primary armament (although a newer model, the 200 mm/50 md. 30), they had a drastically enhanced AA suite and improved armour (120 mm main belt armour, 50 mm armoured deck, 100 mm turret armour, 150 mm conning tower armour). They were very good seaboats and steady gun platforms with excellent accommodation and work space, proofing quite popular with its crews. During the war, the 40 mm md. 28 twin mounts were replaced by quad 40 mm md. 36 mounts, four additional 40 mm twins were added and new FuMo Typ 157, FuMo Typ 44 and FuMo Typ 34 radars were fitted. Four of the 25 mm twins were replaced by 25 mm quad mounts.

Mayu-Klasse Panzerkreuzer

The Mayu was a result of the lack of new treaties and limitations in face of the brewing war. With a significantly increased displacement the ships switched to three triple turrets, added one additional 100 m twin in lieu of the elevated after turret and adopted stronger armour throughout the ship. As a result the class had a main belt of 160 mm, 100 mm armour over the magazines and 60 mm deck armour.

Aircraft carriers

Mihaela-Klasse Flugdeckkreuzer

The Mihaela was the first carrier to be commissioned for the Laywenranian navy. It was built in the aftermath of the second cataclysm. The ship was used for testing carrier aircraft, operations equipment, techniques and operational methods. She was built with three distinctive funnels and a bridge on the right side of the flight deck, but this was removed in 1924 after advice from pilots. The funnels were fixed in the horizontal position with their mouths angled slightly downwards. In 1927, 6 twin 13 mm machine guns were fitted. While delivering a very useful experience and insight in carrier operations, the ship was obsolete and limited by its size and was placed in reserve in 1936. She was later reactivated and served as a training vessel for carrier pilots.

Izalith-Klasse Flottenflugdeckträger

The Izalith was the second aircraft carrier to be completed for the Laywenranian Navy. She was based on the hull of a foreign battleship which was intended to be scrapped according to international treaties, but later sold to Laywenrania under the premise that she won't be completed as a battleship. She still featured an extensive armour for aircraft carriers of this time (155 mm belt armour, 100 mm torpedo bulge, 80 mm deck armour). In 1935, she faced an extensive modernisation to accommodate a longer flight deck for larger aircraft. The lower flight deck was eliminated in favour of two enclosed hangar decks that extended almost the full length of the ship, while the upper flight deck was extended to the bow, increasing its length to 252 m. The total aircraft capacity was increased to 91 planes. Her arrester gear was replaced by a hydraulic system with 9 wires. The hangar and fuel tanks received armour protection and the firefighting system was overhauled and significantly improved.

Yuria-Klasse Flottenflugdeckträger

The ships were the first large, purpose-built, completely indigenous aircraft carriers of the Laywenranian navy. Thanks to her slim, cruiser-type hull they were one of the fastest carriers in the world. The engine uptakes were trunked to the ship's starboard side amidships and exhausted just below flight deck level through two funnels curved downward. The flight deck was 220 metres long, 12 transverse arrestor wires were installed on it. They had a waterline belt with a thickness of 150 millimetres over the magazines, reducing to 100 mm over the machinery and fuel tanks. The deck had an armour thickness of 30 mm over the machinery and 60 mm over the magazines and fuel tanks.

Liviana-Klasse Begleitflugdeckträger

Both ships of the class were originally built as submarine support ships, but were designed to be converted to a light aircraft carrier as needed. Construction of both ships was soon stopped and they were finished as aircraft carriers. They had an arresting gear with six cables and two crash barriers for planes which missed the cables. During the war the light AA armament was improved with the addition of multiple 40 mm and 25 mm guns and in 1943 6 30-round AA rocket launchers were added which were intended to provide barrage fire.

Zinoviya-Klasse Flottenflugdeckträger

The ships were ordered in 1937 and based on the Yuria-class design. The requirement for the class was quite ambitious, requiring high speed, aircraft capacity no smaller than the Izalith, significant AA defences and superior protection. Based on hydrodynamic research, they received a bulbous bow and twin rudders. They were powered by twelve MAKO 8-cylinder diesel engines, an enhanced type of the ones used in the Yuria-class. The engine uptakes were trunked to the ships' starboard side amidships and exhausted just below flight deck level through two funnels that curved downward. The class was fitted with five 500-kilowatt diesel generators, all operating at 225 volts. The flight deck, which was equipped with ten transverse arrestor wires and three crash barricades, had a length of 245 meters and a maximum width of 30 metres. The ship had two hangars, which could be subdivided by fire curtains and were fitted with firefighting foam dispensers.
The armour consisted of 50 mm waterline belt armour, backed by 50 mm of steel in the lower portion. The magazines were protected by 170 mm of armour with a 140 mm deck above them. 55 mm of side armour and 65 mm of deck armour protected the machinery and the fuel storage tanks. Based on experiments, the Zinoviya incorporated a torpedo belt system, consisting of liquid filled compartments outside of the torpedo bulkheads (the outer one beeing a 38 mm thick plate, the inner one beeing a high tensile 25 mm thick plate). Outboard of this were two compartments intended to dissipate the force of the gases of the detonation, including the watertight compartments of the triple bottom. Two forward bow catapults were installed.

Amalia-class

The Amalia was a modified Zinoviya-design, which featured more extensive armour, an increased plane capacity and various detail improvements. A significant difference to previous carriers was the armoured flight deck, consisting out of 75 mm of steel, backed up by a high tensile 20 mm deck. Otherwise, the armour was similar to the Zinoviya-class. The bow was plated up to flight deck level, giving it a unique look among the Laywenranian carriers in service, while improving the airflow and the seakeeping. The three armoured elevators were capable of transporting 8 t in 13 seconds from the lowest deck to the flight deck. The flight deck was, like the previous class, coated with a latex mixture. This proofed advantageous, thanks to lower weight, lower costs and easier maintenance and damage control. The Amalia featured 14 arrestor wires compared to the 10 of the previous class while having the same amount of crash barriers.

Battleships/Battlecruisers

Liara-Class

The concept of the Liara-class was created in a time during which aircraft carriers were still a new and infant technology, while battleships were deemed as too expensive and limited in their uses due to their high value. Further limitations were placed on battleship construction due to international treaties and the limited budgets of the post-war period, favouring a smaller, cruiser-like ship. The second cataclysm highlighted the vulnerability of merchant shipping. While submarines proofed to be a deadly threat, their usage against guarded convoys was limited, as most submarine attacks were still carried out surfaced, relying on the low silhouette of the submarine to prevent detection. To engage these heavily guarded convoys, the need for a surface ship which could outgun enemy cruisers and outrun enemy battleships was anticipated. The final design for these specifications was the Liara-class. Owing to the intended usage, they had large fuel bunkers for a substantial range and rather comfortable accommodation for the crew. They proofed to be excellent seakeeping ships, riding out heavy weather easily. The Liara was the first Laywenranian ship to be equipped with radar in 1936, field testing the FuMo Typ 27

Swetlana-Class

Built as commerce raiders, improved variants of the Liara-class, with stronger armour and improved armament. The most significant difference was the third 280 mm turret super firing the frontal turret, replacing one of the twin 100 mm mounts, which was compensated by the addition of one additional twin mount on each side of the ship. The light AA armament shifted heavily towards less 25 mm guns in favour of more 40 mm guns.

Lana-Class

The Lana-class was the final evolution of the Liara-design, growing again substantially in displacement and dimensions. Due to the threat of old battleships and cruisers escorting convoys it was felt necessary to upgun the old design. The 320 mm gun of the Mahoro-class was chosen as armament, which was fabricated domestically. The armour thickness was again increased, putting the design, which was originally planned as "big cruiser", in the league of battleships. The growth of the design and the impending domination of aircraft carriers led to the cancellation of the ships of the class.

Mahoro-class

The battleships of the Mahoro-class were acquired by Laywenrania after the Second Cataclysm to quickly bolster the maritime defence. While already a few years old, the ships served for over 20 years before money for modernisation was allocated. The quite extensive modification saw the replacement of the steam boilers with diesel engines, the elevation of the main armament increased to 45°, improvement of the armour layout and the Anti-Air Artillery significantly bolstered. The ship had a belt armour of 360 mm, an armoured deck of 90 mm (later 140 mm) and extensive underwater protection, which was later improved by the addition of a torpedo bulge.

Aphrodite-Class

Similar to the Mahoro-Class, these ships were vastly modernised. The extent of the modernisation was far greater though since the larger hull and stronger armament was seen as a more promising investment. With a belt armour of 330 mm, a 155 mm thick deck, up to 400 mm of turret armour and 380 mm armour at the Conning tower, the ships were quite well armoured. They featured extensive underwater protection and were very good seaships.

Submarines

Delfin-Klasse

The Delfin-class were minelaying submarines of the saddle tank type; mines were carried in two stern galleries. These boats were considered successful and provided extensive minelaying service for the Laywenranian Navy during the Cataclysm. In total 20 of these submarines were built. They had a quick diving speed (about 30 seconds) and a reputation for laying well at sea, both at the surface and while diving.

  • Complement: 53

Orka-Klasse

The Orka-class was a medium-sized submarine intended primarily for coastal defence, although they were sea-going. They were based on foreign designs and served as a quite useful tool for Laywenranian shipyards to collect experience in the design and construction of submarines. A total of 35 submarines were built.

Hai-Klasse

The Hai-Klasse was a long-range submarine and the successor to the earlier 1'500 t type. The double hull was divided into seven compartments. With their high speed, good seakeeping and spacious accommodation, they were quite well regarded.

  • Complement: 65

 

Rochen-Klasse

The Rochen-class was probably the most advanced submarine during its time. With a large number of batteries and a snorkel to recharge while submerged, these submarines could stay underwater for far longer times than conventional submarines. The whole design was optimised for underwater operation, including the streamlined hull, the excellent diving times, power assisted torpedo reloading and very good crew accommodations. It was a very quiet submarine for its time and could spend about three days underwater at 5 kn before the batteries had to be recharged, which took about 4 hours. The submarines also featured a very sensitive passive sonar and a freezer for fresh foods.

Landing Ships 

Kyou-Klasse

The Kyou-class landing craft was the primary type of landing craft used by the Laywenranian Navy from late 1930 throughout the whole Third Cataclysm. It featured a bow ramp, which could be lowered to disembark troops and cargo upon landing upon a beach. Due to its hull design, it was decently seaworthy. The hull was constructed out of metal.
