Reinhard's fleet lead by the flagship Brünhild 

Name: Brünhild (named after the Valkyrie Brynhilde, was originally supposed to be the first of an entire class of new flagships)
Origin: Legend of the Galactic Heroes
Type: Command Space Vessel, Prototype Battleship, Reinhard von Lohengramm's personal flagship
In use by:  Galactic Empire, New Galactic Empire
Dimensions: length: 1007m, width: 264m, height: 273m
Mass: Approximately at least 4 million tons
Powered by: Nuclear Fusion Reactors
Propulsion: Fusion Engines (using purified water as medium in space, and environmental air in the atmosphere)
Destructive Capacity: Town level w/ missiles and railguns, town level+ w/ auxillary beam cannons, city level with main cannons, island level with nukes
Durability: Town level, city level against beams (withstood the Whilhelmia's entire firepower), city level with shields
Material: Multiple layers of monocrysaline metal alloy and ceramic foam
Performance: Relativistic (faster than battleships, may be marginally FTL), MFTL (500c) beams, MFTL (about 3 million c) warp speed
Weaknesses: Electromagnetic fields only protect against charged particles and conductive materials. Gravity shields are only offering protection from a certain spot it's concentrated at. Both barriers are less effective at shorter ranges and almost useless against point-blank attacks. The ship's sensors and communications are susceptible to electromagnetic interference and jamming. There's a limit to the lenght of warp jumps and they cannot exit close to massive bodies like planets and stars.
Terrain: Air, Space, Water
Needed Prerequisite for Use: Having at least a skeleton crew trained to operate it (can be remote-controlled or steered by only a few people but then the ship isn't combat-ready)
Average Crew Count: 1171 men
Operational Timeframe: At least several months (radically decreases in case of intense/reckless combat operations)
Weaponry:

  • 25cm neutron beam cannons x 16 (mounted on the uper hull with great traverse and ability to focus every beam on one target)
  • 12cm railguns x 8
  • 6cm electron beam cannons x 8
  • Point-defense lasers x many
  • Missile Batteries x 4 (6-tube systems located on the underside of the hull)
  • Small Craft Hangars x 4 (capable of launching up to 36 Walküre fighters and various transport ships)

Weapons Range: Millions of kilometers (ships are regularly engaging each other from light-seconds away), sensors can reach to billions of kilometers
Special Forms: None
Notable features: Enduring and robust design, beam-reflective coating, verniers and nozzles allows the ship to turn around and change its vectors relatively fast, artificial gravity generators, hover/levitation, electromagnetic and gravitational shields, various sensors, FTL sensors, electronic warfare equipment, advanced command and control interfaces, warp travel by folding space-time, tank-beds and medical bays, shuttle and fighter bays, nukes, massive cargo capacity allowing to deploy mines,troops or carrying other equipment
