| The bitter predecessor of the Iserlohn Fortress, ready to kill its young kin. |
Name: Geiersburg Fortress
Origin: Legend of the Galactic Heroes
Type: Space Fortress/Mobile Space Fortress (after refitted with thursters)
In use by: Galactic Empire, Lippstadt Alliance, New Galactic Empire
Diameter: 45 km
Mass: 40 trillion tons (according to in-series statements, but technically the hydrometal layer alone would be about 160 trillion tons)
Powered by: Nuclear Fusion Reactors
Propulsion: Initially none, later refitted with 12 giant nuclear fusion thursters (syncronised to the extend the lag time is less than 0.1 microseconds)
Destructive Capacity: City level with anti-ship beam cannons, continent level with Vulture's Claw, planetoid level by ramming into the target at full speed
Durability: At least island level+ (comparable to the Iserlohn Fortress)
Material: Hydro-metal armor
Performance: At least sub-relativistic (slower than battleships), beams travel at MFTL (500c) speed, MFTL (likely millions of c) warp travel speed
Weaknesses: Ships and other objects can harmlessly pass through the hydrometal layer it if they possess enough force/toughness but at sufficiently slow speed. The right application of a sufficiently powerful energy weapon can temporally destabilize the gravity generators, making it impossible for the floating weapons to surface. A broading party can infiltrate the fortress and take over its systems from within. Geiersburg Fortress has poor mobility and destroing the thursters at one side can redirect the fortress' frontal charge. Destroying the main power generator would result in the fortress exploding.
Terrain: Space
Needed Prerequisite for Use: Havving the neccessary crew to men the control room
Garrison: Likely more than a million soldiers
Hangar: Can hold up to 16,000 warships and unspecified number of starfighters
Operational Timeframe: Almost indefinite (the fortress is practically self-sufficient, capable of processing food, materials and even fuel)
Weaponry:
- Vulture's Claw
- at least hundreds of fixed or floating anti-ship beam cannon turrets
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: Robust structure protected by a 3km thick spherical layer of liquid metal, artificial gravity which also keeps the hydrometal layer in shape and manipulates its buoyancy to submerge/surface certain turrets or other floating parts, floating turrets that can "swim" in the hydrometal and appear at any portion of the fortress, can generate a powerful gravity well and project it afar, can focus its gravity into a makeshift shield to mitigate attacks, has a weapon system to unleash an extremely powerful x-ray laser strike, various including FTL sensors, forwarship docks in the northern/southern poles, fighter launch ports via extendable tubes in the equatorial trench, possible agricultural blocks and production plants to sustain the fortress' garrison almost indefinitely
Notable Attacks/Techniques:
- Vulture's Claw: Predecessor of the Thor's Hammer, this is an incredibly powerful x-ray laser beam cannon system designed to take out entire fleet formations. Described to have the wavelenght of 100 angströms and the output of 740 million megawatts but by calculations it's far more powerful as the weapon is a near-match for the Thor's Hammer. Similar to the Iserlohn Fortress' superweapon this can recharge rather quick, allowing to shoot multiple times before the enemy fleet would get close. Unlike Thor's Hammer, the Vulture's Claw seems to be a huge fixed cannon instead of a flexible system of floating projectors, most likely because Geiersberg's technology predates the Iserlohn Fortress by more than a century.
