Avalon Fleet Yards is the primary shipyard that services the Fourth Fleet. Located in the Grazer Sector within the trailing rimward section of the Alpha Quadrant, this base has long served as a production facility for starships of all kinds. While other starbases, such as Starbase Bravo provide support for the Fourth Fleet, this shipyard handles the most difficult and time-consuming refits that can't be accomplished at a standard starbase.
History
The Avalon System was first surveyed in the 2290s. It was immediately recognized as an important energy production site, as it was home to both substantial dilithium and deuterium reserves. Facilities were constructed on Avalon II and its largest moon, Avalon Prime, in the years that followed to obtain these valuable substances. In the 2350s, Starfleet decided to expand the facility into a fleet yard to expand production capabilities in the rimward region of Federation space. An Anchorage-class station was towed into position above Avalon II to coordinate the efforts of several dry dock facilities.
In the late 2360s, the facility was expanded significantly to bolster the fleet following Wolf 359. In the 2370s, it was an important facility for the fleet's Dominion War efforts because of its position far behind Federation lines. It was during the 2370s that it became the primary fleet yard for the Fourth Fleet, a role that it retains in the 25th century. By the late 2370s, the original Anchorage-class station was found to be too small for the volume of work faced by the fleet yards, so a new Probert-class spacedock was built there.
As of the 25th century, Avalon Fleet Yards is one of the largest starship production facilities in the Federation, and its importance has only increased following the destruction of Utopia Planitia in 2385.
Facilities
Avalon Fleet Yards is a massive installation with orbital and planet-side facilities. The yard's headquarters and the living quarters for many of its staff are located on Avalon II. The primary orbital facility is Brahms Station, a Probert-class spacedock orbiting between Avalon II and its largest moon, which has been mined extensively for dilithium and has nearly been hollowed out to provide additional space for fabrication and assembly facilities. There are dozens of dry docks around the spacedock and the moon. Additional orbital stations provide research and design, storage, and additional accommodations.
Avalon II Facilities
Avalon II is a Class-O pelagic world with 95% of its surface covered in oceans. Highly unusual for a life-supporting planet, the seas of this world are almost entirely composed of heavy water, that is to say water that contains deuterium rather than hydrogen. While toxic to most carbon-based biologies, it is an important source of fuel for anti-matter reactors, and so Avalon II was initially colonized as a refining station. Floating deuterium refineries bob on the waves around one of the planet's only land masses, which also plays host to the fleet yard's shore facilities. Additional research stations are spread around the planet, both on and under the ocean's surface. There are several dry docks built in shallow areas that allow for the construction and repair of smaller starships capable of planetary landings.
Sato City
Named for early explorer Hoshi Sato, Sato City has a permanent population of 20,000, with housing space for up to 20,000 more transient personnel. Small by Federation standards, this town has all of the comforts one would expect from a Federation colony. Most of the fleet yards' long-term staff live here and take shuttles or transporters into orbit. The landmass here is narrow and rocky, snaking and branching in a way that creates deep fjords between its many peninsulas. This means that most of the structures are narrow and tall, including most of the housing—mainly single-family townhouses. There are a few parks created in the larger flatter areas, and in recent decades floating platforms have been placed in the small coves to provide additional space. The fleet yard's administrative headquarters are in the center of Sato City, which is home to the admiral—though in practice, the admiral is in space more than they are on the ground.
Deuterium Refineries
The planet's deuterium refineries are largely automated. Clusters of these refineries are connected by flexible but tough piping to bunkers on the ocean's floor. It takes many months for the refineries to fill up each bunker, at which point tankers transfer the deuterium to orbital storage facilities. Smaller quantities of deuterium can also placed in cargo shuttles fitted out as tankers from small landing pads at each refinery, and this is often done when ships in orbit need a top-off.
Research Stations
There are multiple research stations on Avalon II, studying the planet's unique ecosphere, mineral deposits, and other areas of interest. The higher density of heavy water means that those on the ocean floor must be specially reinforced. These facilities are run by a mix of Starfleet Science offices and civilian Federation agencies.
Ocean Dry Docks
Made out of concrete reinforced with titanium, several hexagonal caisson structures were built in the shallows near to Sato City. These facilities provide stable, flat surfaces for maintaining and constructing starships capable of planetary landings. Capable of being sealed with forcefields, these large structures can also be used for general storage when necessary. Starfleet has considered creating facilities large enough to construct explorer-type starships, but the resource outlay required to do so would be significant, as the walls of the caissons need to be thicker and thicker as they get wider to compensate for the pressure of the water.
Orbital Facilities
In addition to planetary facilities, Avalon Fleet Yards has a substantial orbital presence, anchored by a new Probert-class station constructed in the 2380s, in addition to free-floating orbital dry docks and smaller subsidiary stations.
Brahms Station
The centerpiece of Avalon Fleet Yards is Brahms Station, a Probert-class spacedock built in the 2380s to replace the Anchorage-class station that had originally been located there. Named for Dr. Leah Brahms, Brahms Station is capable of producing and maintaining starships of all classes and is the primary orbital habitat for personnel who do not live on Avalon II. In practice, this station most often builds frigate and cruiser-sized starships, while larger explorers are built and maintained at dedicated dry docks. It is also where visiting starships in need of only minor maintenance are serviced, to keep the dry docks free for more intensive construction tasks. It is also the primary defensive facility for the Avalon System, using its own substantial arsenal as well as a network of defense platforms to keep the fleet yard safe. The station itself is commanded by a Starfleet commodore or fleet captain in charge of all of the orbital facilities, who reports to the admiral in command of the fleet yards.
Orbital Dry Docks
As with all Starfleet fleet yards, Avalon has many stand-alone dry dock facilities. These support frameworks provide a starship with power and life support while it is being constructed or repaired. They are generally used when a ship needs substantial work done, such as replacing its warp engines or other tasks which must be done with substantial clearance around the ship for maintenance vessels to manuever. Most of these facilities can only handle a single starship at a time, but the larger ones are sometimes used to service more than one smaller ship, especially when the work being conducted is not intensive.
Subsidiary Stations
In addition to Brahms Station, there are a number of smaller stations at Avalon that provide additional engineering support capabilities, storage, and research and development facilities, especially for projects that are too volatile to be conducted on the main station. Depending on their size, they are each commanded by a commander or captain who reports to the commodore on Brahms Station. As of 2401, this group of stations includes 3 Presidium-class facilities, 1 Jupiter-class facility, and the Yard's original Anchorage-class station.
Avalon Prime Facilities
Avalon Prime, formally Avalon IIB, is the largest of Avalon II's three moons, and the only one large enough to achieve a roughly spherical shape. This moon is home to dilithium deposits and was mined extensively throughout the 24th century to the point where these have largely been reduced to just traces. Much of the moon has been excavated and is now home to large scale power generators, fabricators, and storage facilities. Some of these storage bays are large enough to hold mothballed starships, even, and the planetoid now relies on powerful structural integrity field generators to remain intact. The majority of the equipment on Avalon Prime is automated, though there is substantial shuttle traffic in and out to move goods between the moon and the various starship construction projects around the system. Avalon Prime is just outside of transporter range from Brahms Station. These facilities are all controlled by a control center in a Regula-type station body on the moon's equator under the command of the yard's orbital commodore.
Organization
Avalon Fleet Yards is a major command, responsible to both Fourth Fleet Command and Starfleet Engineering. With a total crew of over 100,000, Avalon is under the command of a full Admiral, who is assisted by one commodore or fleet captain each for the shipyard's planetary, orbital, and mobile assets.
