The Utopia Planetia Fleetyards
The Utopia Planetia Fleetyards are on the planet Mars and the Galaxy Class Project was orchestrated from here. The Fleetyards themselves are 16,625 Kilometres above the surface of Mars although there is extensive Research and Development units on the planets surface
All Galaxy Class vessels were built at these shipyards and the yards are home to the Galaxy Class project itself.
The fleetyards offer full repair facilities as well as construction yards. Whilst Galaxy Class ships are regularly serviced or repaired at other Starfleet facilities, each must return to the Utopia Planetia shipyards at least once every seven years for overhaul and in order to allow for all vital systems to be checked.
So far as personnel are concerned, there are generally over five thousand personnel required to operate the fleetyards from research scientists to routine maintenance operatives.
As the fleetyards are so close to Earth, there is very little in the way of recreational facilities available other than the basics. Indeed, some starships are better fitted out than the fleetyards and the personnel particularly enjoy the refits as all that the ship offers entertainment wise is available around the clock, provided of course that the ongoing maintenance or repair works are not interfered with.
Personnel rotation is ongoing although most personnel expect to work at least a six monthly cycle.
