The Starbase Obsidian is an E class Starbase, currently seated between the Romulan and Cardassia Empires. Utilizing a 24 hour rotation period, Starbase Obsidian is able to maintain an Earth based time system. The base has a net height of 5.5 km, with a total height of 5.8km if the various anntennae are included in the measurements and measures 3.8km at its widest point. Split into nine segments according to functionality, the base has 1200 decks, with an average deck height of 4.5m. Allowing for the thickness of the deck itself, this results in a mean floor to ceiling height of 4.0m. Although the base is mainly geared up for oxygen breathing occupants, the life support systems are able to be reprogrammed where necessary to provide suitable environments for beings with different requirements.
Summary:
Base height: 5.5km
Width: 3.8 km
No of Decks: 1200
Deck Height: 4.5m (4m net height, 0.5 mean deck thickness)
Diurnal Period: 24 hours

The uppermost 45 decks of the structure, much like a Federation Starship, comprise the 'brains' of the Starbase. Command facilities such as Ops are located here, together with service meeting rooms, access to in-system and interstellar communications antennae and Commissary facilities for senior duty officers. Like all sections, the command Level also hosts a dedicated emergency medical ward primarily for triage prior to the transfer of a patient to the main hospital decks (if necessary).



The 6 Docking Rings are divided into two sections, the Upper Ring and the Lower Ring. As a whole it contains many facilities that make it reminiscent of a ground based Space port. From hotels, hospitality services and shopping malls, to Space Traffic Control, Civilian Customs, Immigration, and more are housed within the 150 decks of the Upper Docking Ring.
Upper Docking Ring

The Lower Space Dock is divided between civilian and military use. Starfleet shuttle bays, Fighter Docks and cargo storage space can all be found in the area of the Lower Ring.
Lower Docking Ring

The Upper Utility Ring is primarily devoted to serving the commercial and leisure needs of both the permanent and the itinerant residents of Starbase Obsidian. The Starbase computer core is also located in this section.
This Portion of the base remains empty.

The Station’s primary residential facility.

Across 150 decks the Research Ring of Starbase Obsidian is a virtually self contained scientific and medical research and treatment facility. Hospital and Veterinary clinics share bulkheads with forensic science laboratories, computer sciences, geosciences etc. All known disciplines are catered for in this remarkably well equipped scientific research centre.

Much of the Engineering section of the Starbase is restricted access due to the sensitive nature of the work done there. However, the Space Observation decks are open to all and contain a very good restaurant with spectacular views of space.

The travel core is the primary method of travel between the various modules of the Starbase. Travel within the individual modules is via a network of standard turbolifts.
The travel core consists of six high speed mag-lev tracks which extend the entire length of the starbase. There are 14 main stations spread between the population centres of the starbase.
Each Mag-Lev car has three levels and holds up to 30 persons per level. Entrance to the car is via any level.
Average travel time between the stations is 2-3 minutes. Total travel time from top to bottom is generally over 30 minutes although in emergency situations, deployment can be accelerated to under 5 minutes.
The timetable of each car is staggered and varies according to time of day, shift changes and starbase alert status.
The travel core is totally self contained and self pressurised. It contains airlock seals to isolate the various modules. In a critical damage alert all seals engage to protect the inegrity of the station.
A travel pass is required to access the travel core services. Itinerant visitors from non Starfleet or allied military vessels do not have access to the travel core.
Starbase Obsidian utilizes six mark 85 LCARS computer cores operating in tandem, providing superior capabilities for data compilation, research and data analysis. All of the cores are connected via a bio-neural network that can operate data transfer levels approaching 1000 teraquads of data per second. Specific details of the computer core design including technical specifications are classified.
The Starbase computer cores are among the most advanced in the federation, considering Starbase Obsidian's strategic location, the highest levels of data capability are not only necessary but essential, considering the vast amounts of data recovered from starship patrols and intelligence gathering operations needed for the defense of Starbase Obsidian.
The computer cores are located in the Upper Utility Ring.
