Starbase 24 is an Ournal/Spacedock class Starbase, although to the many people who work there, the base is affectionately referred to as  'The Bionic Mushroom'

Orbiting Frontera, an earthlike, class M planet on the Federation/Klingon Border which has a 24 hour rotation period, Starbase 24 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.

Decks detailed in red are restricted to Starbase 24 personnel only.

Command Level (45 decks)

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 Internal Transport System

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.

The Computer System

Starbase 24 utilises 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 24'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 24.

The computer cores are located in the Upper Utility Ring.
