Ship classes of the imperial navy


Ship classes of the Imperiale Marine

This catalogue gathers basic facts about imperial naval vessels and will be updated as new ships appear.

When Leonism made a breakthrough in nuclear fusion power technology in 2014, it became clear that the future of the navy would be ships run on fusion reactors and thus near limitless power and range. Naval Laser weaponry would also be much more feasible. However, as it takes a while to build ships, and Leonism has a sizeable fleet of pre-fusion technology warships, the Marine still mostly consists of ships run on fossil fuels (mainly gas-turbines) or nuclear fission reactors.

Corvettes

Small warships under 100 m, usually commanded by a lower ranking officer. They are mostly used for coastal patrols, escort duty, minelaying and flanking attacks. Specialist classes exist for anti-submarine warfare and special forces insertion.

Bremen class
Individual ships named in RP so far: Bremen, Sandhausen, Hastedt

Mainstay of the imperial fleet, possibly the most numerous warship class in Lazarus, with over a thousand built. Conventional design.

Length: 92 m
Width: 15 m
Displacement: 1500 t
Crew: 40
Power Plant: gas-powered turbine engine
Speed: 60 km/h cruise, 110 km/h sprint
Endurance: 2 weeks or 16800 km.
Armament:

  • 1x 155 mm AK155 artillery turret

  • 1x 66 mm FLK-66 rotary multipurpose cannon

  • 20 torpedoes

  • 2x MRM-6 missile launcher with 6 missiles each (can load anti-ship, anti-air or anti-tank missiles)

Combat range: 30 km (missiles up to 120 km)

Meteor class

A relatively new corvette design in catamaran hull form, it emphasizes speed over every other design characteristic. This makes the Meteor ideal for hit-and-run deployments of special forces or as a fast-attack craft. Its hull is built with a minimal radar signature in mind, giving it stealth characteristics. When it was designed in late 2014, naval fusion reactors of the required sizewere not yet available, but rumours persist that some ships were retrofitted with them later for an even greater performance.

Length: 74 m
Width: 19 m
Displacement: 1800 t
Crew: 36, can carry up to 30 additional soldiers for a few days
Power Plant: 2x high-performance gas-turbine (alleged variants with 300 MW fusion reactors)
Speed: 95 km/h cruise, 133 km/h sprint
Endurance: 1 week
Armament:

  • 2x 66 mm FLK-66 rotary multipurpose cannon

  • 2x MRM-16 multipurpose missile launchers

  • 24 torpedoes

  • 4 11 mm heavy machine guns

Combat range: 5 km (missiles up to 120 km)

Frigates

Mid-sized warships, typically between 100 and 150 m in length, designed for operating independently or as part of a screen protecting other ships, these are the backbone of the imperial navy and can often be found escorting merchant ships.

Protector class
Individual ships named in RP so far: Seehund

The standard multipurpose frigate with a focus on anti-surface warfare and coastal bombardment. Several hundred were built. It has a helipad with a single helicopter.

Length: 140 m
Width: 32 m
Displacement: 8000 t
Crew: 200, with additional quarters for up to 100 marines on some individual ships.
Power Plant: gas-powered turbine engine
Speed: 55 km/h cruise, 96 km/h short range sprint.
Endurance: 4 weeks or 31000 km
Armament:

  • 6x 270 mm "Nebelwerfer" rocket assisted artillery, built into two rotating turrets of 3 guns each.

  • 4x MRM-36 multipurpose missile laucher with 36 missiles each.

  • 6x 66m mm FLK-66 multipurpose rotary cannon.

  • 80 supercavitating torpedoes.

  • 2x "Illuminator" 5 MW point-defense Laser turrets.

Aircraft complement:

  • 1x H19 medium naval helicopter

Combat range: 90 km (missiles up to 120 km, the helicopter can fly for 400 km)

Skylancer class air defense frigate
Individual ships named in RP so far: Seeadler

A state of the art ship class only being built since 2018, with only a handful finished so far. Designed mainly for anti-air protection, the Skylancer is notorious for its oversized fusion-power reactor driving an entire battery of Laser weaponry. A single ship can easily defend against an entire squadron of enemy aircraft and their missiles. The point-defense heavy ship can also intercept missile and drone swarms with ease. In direct ship to ship combat, it lacks range to fight beyond the horizon, but any hostile vessel coming into Laser range is in trouble.

Length: 138 m
Width: 24 m
Displacement: 6200 t
Crew: 156
Power Plant: 900 MW "M900" nuclear fusion reactor
Speed: 89 km/h cruise, 132 km/h sprint
Endurance: Limited only by crew fatigue and supplies, as the fusion reactor needs only water as fuel. Typically stays no longer than 8 weeks at sea.
Armament:

  • 6x "Lichtbringer" 20 MW naval Laser cannon, arranged in three turrets of two lasers each

  • 52x "Illuminator" 5 MW point-defense laser

  • 4x UBA supercavitating underwater turret against submarines and torpedoes

  • 2x MRM-16 multi-purpose missile launchers with 16 missiles each

Combat range: Lasers about 15 km, missiles up to 120 km

Battleships

Battleships are the heaviest and most powerful warships, but are considered obsolete by many due to the superior strike range of carrier-based aircraft. Imperial naval doctrine begs to differ and fields mixed fleets, thinking battleships can still make a difference with adequate protection against aircraft.

Imperator class
Individual ships named in RP so far: Invictus

These behemoths match even carriers in size and are the most heavily armed ships in the imperial navy. Their signature main guns move the entire ship tens of meters to the opposite side if fired as a broadside. Very important for their survival is their secondary air defense and point defense armament protecting the ship against missiles and torpedoes. Due to their immense cost and limited role, only 14 ships of this class exist.

Length: 326 m
Width: 55 m
Displacement: 118000 t
Crew: 1612
Power Plant: 1200 MW nuclear fission reactor
Speed: 42 km/h cruise
Endurance: 1 year
Armament:

  • 16x 489 mm "Langerhans" rocket-assisted artillery guns, arranged in four rotating turrets of four guns each.

  • 10x 270 mm "Nebelwerfer" rocket assisted artillery guns, as separate single gun turrets.

  • 24x 66 mm FLK-66 multipurpose rotary cannon.

  • 38x "Illuminator" 5 MW point defense Laser turrets.

  • 10x MRM-36 multipurpose missile launchers with 36 missiles each.

  • 10x UBA supercavitating underwater guns for anti-submarine and anti-torpedo warfare.

Combat range: 120 km

Aircraft carriers

Aircraft carriers act as mobile bases, their main role is power projection. They are usually the largest military ships, due to the fact that they need a sizeable length to act as mobile runways. Usually lightly armed and relying on their screens and aircraft for self-defense. The Imperium uses aircraft carriers less extensively than other blue-water navies, as they still hold their battleships in high regard and land-based aircraft tend to have long ranges.

Dominator class

An older carrier class serving as escort carriers, these are at the lower end of the typical carrier size and carry a smaller fighter complement than full sized fleet carriers.

Lenght: 310 m
Width: 72 m
Displacement: 78000 t
Crew: 2217, with quarters for up to 1000 more
Power Plant: 2x 600 MW nuclear fission reactors
Speed: 55 km/h cruise, up to 80 km/h short range sprint
Endurance: 2 Months or 79200 km
Armament:

  • 5x 66 mm FLK-66 multipurpose rotary cannon

  • 4x "Illuminator" point defense Laser turrets

Aircraft Complement:

  • 36x R22T multirole fighters

  • 2x F71A STOL multirole transport aircraft

  • 2x H19 medium naval helicopter

Combat range: 5 km (FLK 66 cannon), strike range of the R22T aircraft is 1200 km

Support vessels

A variety of ships that serves different functions, all they have in common is that front-line combat is not what they are made for. These include tankers, logistics vessels, hospital ships, transports, freighters, and landing craft.

Goldesel class tanker

The Goldesel class is a fueler, designed only to support other vessels with fuel. With the advent of usable naval fusion reactors, the remaining days of this class are numbered. At the moment, only 5% of the fleet runs on fusion power, with the remaining 95% split between 30% fission and 65% fossil fuels. Thus, the Goldesel still performs an important function.

Length: 119 m
Width: 29 m
Displacement: 5700 t
Crew: 22
Power Plant: traditional diesel engine
Speed: 52 km/h cruise
Endurance: planned for four weeks, the fuel in its tanks would last for over a year on its own
Armament:

  • 1x 66 mm FLK-66 rotary multipurpose cannon

Combat range: 5 km
Fuel storage capability: 4200 t

Atlas class Fleet Support Ship

A mobile logistics hub, this ship can support an entire fleet with various supplies for weeks and also can serve as a resupply base for marine invasions. A hospital bay with 10 intensive-care beds is also on board, enabling a secondary function as hospital ship. It is only lightly armed, requiring protection from other ships to survive combat. It makes a nice big target otherwise.

Length: 265 m
Width: 63 m
Displacement: 45000 t
Crew: 987
Power Plant: 700 MW nuclear fission reactor
Speed: 48 km/h cruise, 76 km/h sprint
Endurance: 1 year, though its supplies are usually emptied much faster if accompanying a fleet
Armament:

  • 3x 66 mm FLK-66 multipurpose rotary cannon

  • 1x "Illuminator" point defense Laser turret

  • 2x MRM-6 multipurpose missile launcher, with 6 missiles each; can carry enough missiles for several thousand reloads (!)

Combat range: 5 km (up to 120 km for the missiles)
Supply cargo hold: Up to 25000 t in total
