Utopia Planitia Fleet Yards

Type Orbital starship yard
Classification Construction-, maintenance- and repairing facility
Affiliation United Federation of Planets
Supervisor ASDB, Starfleet
Status Operational
Description Large shipyards of Starfleet in a geosynchronous orbit of the planet Mars, which is located exactly 16625 km above Utopia Planitia on the surface of Mars, the historical landing area of one of the first Mars probes and serves for the construction as well as the repair and maintenance of starships. The Utopia Planitia Fleet Yards therefore conists of a multitude of drydocks, space stations and other orbital facilities, for instance construction facilities of the San Francisco and Utopia Planitia type. Due to the large number of facilities, the yards have a remarkable capacity and, in contrast to the older yards in the orbit of Earth, are able to construct or repair more than one starship simultaneously. In the big space stations, but partially also in the drydocks themselves, there are coordination, planning and designing centers, because the Utopia Planitia Yards are jointly responsible not only for construcion, but also for design and pllanning of the infrastructure and systems of the starships in accordance with the project specifications. For instance, it is the task of the theoretical propulsion group to design the warp drive of the starships. In the last 50 years, the Utopia Planitia Yards, with support of the other facilities under direct authority of the Advanced Starhip Design Bureaus (ASDB) of Starfleet, were completely or jointly responsible for design and construction of more than a dozen starship classes, including the Excelsior class, the Galaxy class, the Nebula class, the Defiant class, the Intrepid class and a large number of mixed classes that became necessary because of the Dominion war, quickly produced by the exclusive use of already existing modules, for example the vessels of the Yeager, Centaur and Curry type. Furthermore, the Starfleet production plants of the yard are responsible for the series production of the shuttle types 6, 7, 9A and the Danube class runabout and the work bee. Additional facilities are located on the surface of the planet, including a department for research and development (R & D) of Starfleet equipment. Therefore we can rightly claim that the Utopia Planitia Fleet Yards which are now operational for many decades, belong to the largest construction facilities of this kind in the Federation.

   07/06 The ASDB submits the propulsion specification of the upcoming Galaxy class project to the Utopia Planitia Fleet Yards. The specs include a travel speed of warp 7 and a maximum speed of warp 9.3.
  July Official approval and beginning of the Galaxy project with simulations, designing and the prototype construction of single systems in the Utopia Planitia Fleet Yards and other ASDB facilities.
   12/24 The revised specs of the Galaxy class are submitted to the Utopia Planitia Fleet Yards. Due to the considerable reduce of the mass, improved materials and internal changes, the travel speed has been raised to warp 6, the maximum speed to warp 9.6.
2347 Beginning of the construction of the Galaxy class prototype in the Utopia Planitia Fleet Yards. Designing and simulations continue.
   06/03 The first two spaceframe parts of the USS Galaxy are gamma-welded during a short ceremony in the Utopia Planitia Fleet Yards.
   04/16 First tests of the complete system model of the Galaxy class in the Utopia Planitia Yards.
   04/18 The complete system model of the Galaxy class ist presented to Starfleet in the Utopia Planitia Fleet Yards.
   05/05 The Galaxy class prototype, the USS Galaxy, exists for the first time in an spaceworthy version and departs from the Utopia Planitia Yards for propulsion tests.
2357 The spaceworthy version of the USS Yamato departs from the Utopia Planitia Fleet Yards for propulsion tests.
The USS Galaxy is comissioned in the Utopia Planitia Fleet Yards.
2358 The spaceworthy version of the USS Enterprise-D departs from the Utopia Planitia Yards for a flight test program.
2361 The USS Yamato is comissioned in den Utopia Planitia Fleet Yards.
  10/04 The USS Enterprise-D is comissioned in the Utopia Planitia Fleet Yards.
2366 Official approval of the experimental Defiant project supervised by Admiral Batelle Toh of the ASDB and beginning of the prototype construction in the Utopia Planitia Fleet Yards under the supervision of Commander Benjamin Sisko.
2369 End of the basic construction of the experimental prototype USS Defiant in the Utopia Planitia Yards.
2370 The construction of the first starships of the Intrepid class is finished in the Utopia Planitia Fleet Yards.
The Defiant class prototype departs from the Utopia Planitia Yards to the Antares Fleet Yards near Antares IV for final tests and the comission.
2372 After the USS Defiant has proved itself against the Domion, limited series production of the Defiant class begins; 2 additional starships are constructed in the Utopia Planitia Yards.
2373-75 The extreme losses of starships Starfleet must take during the Dominion war, and the generally increased demand for war ships for the tactical fleets of the Federation require the construction of a large number of temporary vessels, that are exclusively based on components of established classes which already exist or can be constructed quickly, contain only the most necessary systems and crew facilities and have reinforced defensive systems. "Kit-bashed" starships of the Yeager, Curry and Centaur type are constructed in the Utopia Planitia Fleet Yards at this time and immediately deployed at the front. It is planned to deconstruct these starships, which haven't even received an official registry number very often,  after the end of the war, provided that they haven't been destroyed until then.
