The spire is two kilometers in height. It may be either built entirely on a planet's surface, or the base can be built on a planet while the main body is built in a shipyard and docked later. Most spires are built with recycled frame and armor parts from Chiharu-class Flagships and are built to last, with an estimated lifespan of at least 100 years.
In the event of an emergency, the Spire is equipped with anti-gravity systems that allow it to detach from its base and rise into planetary orbit, where it can wait for the emergency to pass. If leaving a planet, the spire must be towed by starships to its position as it has no STL or FTL drive systems. The interior is compartmentalized with Forcefield-Nested Isolation Doors and is environmentally contained.
See Damage Rating (Version 3) for an explanation of the damage system.
Dominating the landscape, the spire is a vertical military base and industrial center in a way that is somewhat equivalent to a starbase. Spires are used as command centers for cities or even whole planets. The spire has a capacity of over 250,000 people. It is also compatible with the Ke-P3 Series Defense Towers and can serve as the center tower in a planetary shield network.
There are 500 above-ground levels of the tower (4 meters each).
The Spire's upper levels contain:
The Spire's middle levels are used for industrial purposes. They contain:
The spire's base section contains:
